Waste disposal charge will cost a typical Hong Kong family HK$51 a month

Environment minister reveals range of fees intended to meet target of a 40 per cent reduction in household waste by 2022

Hong Kong’s households will have to shell out around HK$33 to HK$51 a month to dispose of their rubbish when a long-awaited quantity-based charging scheme designed to change behaviour and reduce waste comes into force in two years.

Environment minister Wong Kam-sing said on Monday that charges for municipal solid waste – rubbish generated from homes, offices, factories and restaurants, a third of which comes from kitchens – would be imposed on all sectors in one go for the sake of fairness and in line with the “polluter pays” principle.

“Quantity-based waste charging aims to create financial incentives to drive behavioural changes in waste generation,” Wong said. “The biggest aim is to reduce overall waste disposal, not to increase government revenues.”

Residential buildings, village houses and street-level shops that use government refuse collection services will be required to buy one of nine types of rubbish bags of varying size, priced at an average 11 cents per litre. The charge will be 30 cents for the smallest, 3-litre bag, while the biggest 100-litre bag will cost HK$11.

A three-person household opting for the standard 15-litre bag – roughly the same size as a supermarket plastic bag – will pay about HK$1.70 a time, running a tab of about HK$51 per month. It will cost HK$1.10,or HK$33 per month, for 10-litre bags.

Oversized items that cannot fit into any of the nine designated bags must be tagged with a label that costs HK$11 for disposal.

Sold in packs of 10, the bags will be available at 4,000 sales points, including convenience stores, post offices, petrol stations and special vending machines.

Commercial and industrial buildings using private collection services will pay a landfill “gate fee”, based on the weight of the rubbish they produce. The tip fees will be set between HK$365 and HK$395 per tonne.

Details of the charging scheme were revealed by the Environmental Protection Department on Monday after years of public engagement. A bill will be tabled at the Legislative Council before the summer and, following its passage, the public will be given 12 to 18 months to prepare for the charging scheme. Full implementation is expected in the second half of 2019.

The average Hongkonger throws out about 1.39kg of household waste per day. A target was set in 2014 to slash that figure by 40 per cent by 2022. Wong said the city’s municipal solid waste had increased by over 80 per cent over the past 30 years, far outpacing the population growth of 34 per cent.

He said the government would step up enforcement at refuse collection stations and bin sites. Legislation could also empower public officers to carry out enforcement and spot checks within common areas of private residential estates.

Fixed penalties for non-compliance have been set at HK$1,500.

Wong said the charges – which will be in place for three years – were “acceptable” and in line with practices in Taipei City and Seoul, both of which have seen significant waste reduction since levies were introduced.

World Green Organisation policy advocacy manager Angus Wong Chun-yin welcomed the scheme but said the departments involved would need to be clearer about how to divide labour and monitor and carry out enforcement in estates. “It still seems a bit clumsy,” he said.

Greeners Action executive director Angus Ho Hon-wai said the charging scheme’s impact would be greater if rates were set higher.

“At this rate, I believe it will be difficult for the government to meet the 2022 waste targets,” he said.

“But as a starting point, we can acquiesce.”

He said the government also needed to consider how property management companies of commercial buildings will divide tip fee costs equitably among tenants.

“What if I produce very little waste, why should I help pay for others? This is something they will need to think about.”

David Suzuki, climate science’s caustic Dr Doom, rips into consumerism, hails China’s green tech

Japanese-Canadian geneticist offers gloomy prognosis of looming catastrophe, and rubbishes the idea that humanity can innovate its way out of its problems

http://www.scmp.com/print/lifestyle/article/2079813/david-suzuki-climate-sciences-caustic-dr-doom-rips-consumerism-hails

David Suzuki is a force of nature. The Canadian geneticist turned celebrity champion of the environment is operating on severe jet lag, two hours’ sleep and an ever-heightening world-weariness. But he fires off epithets, facts and acerbic quips with a vigour that’s as implausible as the ageless glow of his skin.

“Humans value growth; that’s like cancer cells,” Suzuki, 80, says. We’re overpopulated and live in a finite world but are deluding ourselves that the opposite is true, he says.

“We’re an invasive species,” he adds, forecasting that a Spanish-flu-like epidemic might cut back swelling populations in the near future.

The developing world is a target of his ire for its booming populations, a position he admits is controversial. “We don’t talk about how these populations are growing too fast because we’re told it’s racist to say that.”

Touching down in Hong Kong to deliver a rallying speech at City University that kicks off its inaugural lecture series on sustainability, Suzuki does not mince words on stage nor during interviews, in which he refuses to suffer optimists.

He has a reputation as a fearsome figurehead of Canada’s environmentalists, having, on occasion, responded to detractors in expletives, and proved a slightly scary interviewee. At times, he emanates a grandfatherly warmth; at others, a wry impatience that veers on the grouchy.

“Yeah, humans are just so smart, we’re just so, so smart,” he says, rolling his eyes at the suggestion that humanity might save itself through its own inventiveness. This quality, though marvellous in some respects, is what enabled us to develop in ways that are unsustainable.

“We have the internet, that’ll fix things,” he says sarcastically. He finds effusive optimism of this sort not only deeply distasteful, but also dangerous, as it vindicates inaction in the face of creeping adversity.

That man-made solutions to climate change’s increasingly disastrous impact, by way of geoengineering, or conquering new planets as recently proposed by Tesla entrepreneur Elon Musk, might be just around the corner, are beliefs he calls delusional. The answer lies not in new inventions, but in scaling back big time and pushing for others to do the same.

The solution to our problems goes far beyond paltry gestures such as switching to energy-efficient light bulbs, he says, but doesn’t offer any specific suggestions besides a total overhaul of the status quo, and mobilising society to campaign for its rights to clean resources.

“Since I arrived in Hong Kong people keep saying ‘free the market, you gotta free the market’,” Suzuki says, waving his arms flamboyantly. “The market” is a human construct, he adds. It’s not a preternatural force that’s beyond the control of humans – it can be tamed.

Needless to say, Suzuki is no proponent of deregulated capitalism, nor is he hopeful about the future prospects of mankind within the current framework of the global economy. “Corporations don’t give a s*** about us,” he says.

He argues that what’s happened is that we imbue “the market” with an almost transcendental power while relegating the natural world to a position of servitude. This sanctions our plundering of the Earth with ever greater and prospectively more dangerous ingenuity.

On China, he has a nuanced take: “I vowed never to go back because of the air pollution. Now China has invested in green technology because it’s had to – the pollution is killing people. It’s becoming a world leader in green tech.”

On recently elected US President Donald Trump he is far more critical: “We’ve moved from a biocentric point of view to an anthropocentric one. It’s all about me, me, me – and Trump is the cultural expression of that,” he says.

We once respected nature and bowed to its demands. Now we expect it to do our bidding and plunder its resources with an absurd expectation that they are infinite and a grandiose sense of entitlement.

“There’s no limit to what we want,” he says. “You walk down the street and see people in jeans that companies have ripped for them. I think that’s disgusting.”

Suzuki, a Vancouverite and third-generation Japanese-Canadian, rose to prominence as a TV presenter and environmental activist during and after the decades he spent as a research scientist.

His family suffered internment during the second world war, and, in its aftermath, were forced to relocate to the east of the Rocky Mountains after the government sold off their dry-cleaning business.

Suzuki attributes to his parents’ need to scrimp and save his own distaste for the materialist values that flourished after the war.

“My parents taught me not to run after money,” he says.

The fledging scientist earned his PhD in biology from the University of Chicago, and later became professor of a genetics department at the University of British Columbia, specialising in fruit flies.

He went on to host several documentaries, radio and TV shows, among them the internationally popular science programme The Nature of Things, which cemented his place as a household name.

“When I started doing those shows, Canadians were scientifically illiterate,” he recalls. “I had hoped that by helping disseminate information people would get better about making the right decisions.

“I’ve had to alter that belief – now we have the internet and access to so much information, we just read the stuff we want to believe.”

In the late 1970s, during the shooting of The Nature of Things, he interviewed the indigenous people of the Haida Gwaii archipelago on the north coast of British Columbia about protests they were holding against the cutting down of their forest.

These encounters proved life-changing for Suzuki, who has since campaigned tirelessly for the rights of indigenous cultures and has been adopted into one tribe.

“I’ve been welcomed into the eagle tribe – I’m an eagle,” he says. His adoptive tribe sees men and animals as one and the same, an idea Suzuki says is supported by recent research showing that humans and animals share many chromosomes.

He believes they are among the only societies who live sustainably, within their means and with respect for the natural world. He says science now backs many of their conceptions of man’s place in the world as part of an interconnected matrix.

With 55 books under his belt, a foundation in his name, and environmental campaign work spanning decades, Suzuki admits he’s exhausted, angry and prone to moments of despondency.

He has been a particularly active force when it comes to debunking climate deniers and the industry lobby groups that support them. “Companies that put their own profit over the survival of the planet – that’s evil.”

The past year has been a particularly bad one for his ilk. Deadline upon deadline set by climatologists and transnational alliances to offset climate change’s increasingly palpable impact have been flouted.

And what has emerged is an increasingly polarised world, unverifiable information chaos and a climate change denier at the helm of the world’s most powerful nation.

Suzuki remembers the evening of last year’s US elections. A party with his wife and friends in Massachusetts had disbanded early when the results became apparent. “I left that night worried that some of my friends might kill themselves,” he says.

A few weeks later he would find himself reading a particularly dismal report from an environmentalist’s research project that forecast climatological doom in our near future owing to methane being released from the Arctic as the permafrost thaws.

“I couldn’t move for a week after I read that,” he says. “My grandchildren have a very uncertain future.”

A family man with five children – three from his first marriage – he admits that for a proponent of population control his ecological footprint isn’t the most admirable.

“You have one kid, and you think, this is great, let’s have another,” he says. “And grandchildren are even better.”

His daughter, Severn, is like her father. At the age of 12, she travelled to Rio to give a speech at the summit and has since followed in her father’s footsteps by becoming a prominent environmental activist. When Suzuki needs to escape he retreats to the Haida Gwaii reservation, where Severn now lives with her husband and two sons.

“My grandchildren keep me from despair,” he says. “My grandchildren are what keep me fighting. Because we’ve got to keep fighting, otherwise – what’s the point?”

Lung disease costs the United Kingdom £11bn every year – report

https://uk.news.yahoo.com/lung-disease-costs-united-kingdom-11bn-every-report-015300294.html

New figures show lung disease is costing the UK more than £11bn every year, prompting criticism the NHS and governments are not doing enough to tackle one of the country’s biggest killers.

A report by the British Lung Foundation (BLF) says, despite such a large healthcare bill for respiratory conditions, there has been little change in mortality rates over the last 10 years.

The Foundation says 115,000 people die from lung disease every year – one person every five minutes.

More than 12 million people are living with a lung condition in the UK.

It also claims the UK has the highest mortality rates for children with asthma in Europe.

According to the BLF, of the £11.1bn that lung disease costs every year, £9.9bn is spent by the NHS.

A further £1.2bn is lost in the wider economy through things like days off work.

There are calls for the governments and NHS in both England and Scotland to create special taskforces for lung health, and produce new five-year strategies for tackling lung disease.

Dr Nicholas Hopkinson, Medical Adviser for the British Lung Foundation, told Sky News air pollution is a major part of the problem.

He said: “In this country, the estimate from the Royal College of Physicians is that there are about 40,000 excess deaths per year caused by air pollution and one of the things in parallel with a respiratory task-force would be a new Clean Air Act.

“We need for the Government to be setting strong binding targets and actions to reduce this air quality problem.”

At the Hospice of St Francis in Hertfordshire, a group of patients with pulmonary fibrosis take part in a fortnightly exercise group.

Their condition will get worse. Some will take years to deteriorate and others will worsen more quickly.

One of the patients, Peter Bryce, runs the Pulmonary Fibrosis Trust. He told Sky News groups like his offer vital support.

“Coming here is like joining a family. The people understand the nature of this illness and it’s easy to relate to them and share experiences and support each other. It’s brilliant,” he said.

The Hospice only receives 20% of its funding from the NHS – but it is this sort of support group campaigners want to see more of to help those with lung conditions.

The Department of Health insists it is doing more to tackle lung conditions.

A DoH spokesperson told Sky News: “It is plainly wrong to suggest that tackling lung disease is not a priority – government research funding has risen to over £25 million, our policies have helped reduce smoking rates to a record low and Public Health England has extended its successful ‘Be Clear on Cancer’ campaign to raise awareness of the symptoms.”

Hong Kong can create its own smog, researchers say

Scientists from Hong Kong and Macau found one day in which pollutants were formed when dirty air was not blowing from the north

Smoggy days are often blamed on regional pollution and weather, but at least one recent scientific study has shown that the city can, under the right conditions, “form its own smog”.

The study by Hong Kong and Macau air scientists argued that a rapid build-up of particulate matter in the air – a key component of smog – was possible even in the absence of northerly winds that can transport pollutants from afar.

The evidence boiled down to at least one particular sunny September day in Hong Kong in which a “land-sea breeze” pattern formed along with weak winds far below average speeds.

The scientists observed a rapid rise of photochemical activity during mid-afternoon, in which ozone and nitrogen dioxide skyrocketed along with increasing sunshine.

“It is clear that there was a rapid increase in particulate matter (PM) concentration on this day when we were not really affected by external meteorological conditions. It’s not easy to argue in this case that winds were blowing PM to Hong Kong from the region ,” said co-author Professor Chan Chak-keung, dean of City University’s school of energy and environment.

The culprits, he said, were most likely local sources such as vehicles or industrial emissions, which contain nitrogen oxides and volatile organic compounds. The latter pollutant is also found in products such as organic solvents, paints and printer inks.

Chan’s team investigated “episodes” – days with high PM concentrations – in one-month periods in each of the four seasons from 2011 to 2012 at the University of Science and Technology’s air quality research supersite.

Other episodes across the seasons were also observed with high local photochemical activity, but those days also came under the influence of transported air from the north, making it less clear what was actually local or regional.

The paper was published in scientific journal Atmospheric Chemistry and Physics in November.

“Of course, regional sources play a role but [this research] shows that under the right conditions, PM can build up and Hong Kong can form its own photochemical smog.”

Photochemical smog is created when nitrogen oxides react with volatile organic compounds in the air under sunlight. It leads to the formation of ozone. This hazardous pollutant facilitates the formation of the tiny particles, small enough to be inhaled deep into the lungs and even into the bloodstream.

The particulate matter in the air lowers visibility, turning the sky smoggy and gives it a lurid orange tint at dusk.

The Environmental Protection Department usually points to meteorological influences such as northeast monsoons when the air quality health index hits “very high” health risk levels.

During a bout of high pollution last Thursday, it said: “Hong Kong is being affected by an airstream with higher background pollutant concentrations. The light wind hinders effective dispersion of air pollutants.”

It added that the formation of ozone and fine particulates during the daytime resulted in high pollution in the region.

Chan said most smoggy days were doubtless a result of regional factors or pollution. But he said the study’s findings warranted more research on how PM was formed and pinpointing its sources.

India reported 1.1 million deaths due to air pollution in 2015, says a global study

http://economictimes.indiatimes.com/news/environment/pollution/india-reported-1-1-million-deaths-due-to-air-pollution-in-2015-says-a-global-study/printarticle/57145119.cms

The government here may be in denial mode on linking premature deaths to air pollution, but a new study on global air pollution by the US-based institutes claims that the India’s worsening air pollution caused some 1.1 million premature deaths in 2015 and the country now “rivals China for among the highest air pollution health burdens in the world.”

The special report on ‘global exposure to air pollution and its disease burden’, released on Tuesday, noted that the number of premature deaths in China caused by dangerous fine particulate matter, known as PM2.5, has stabilised in recent years but has risen sharply in India.

It also said that both the countries together were responsible for over half of the total global attributable deaths while India had registered an alarming increase of nearly 50% in premature deaths from particulate matter between 1990 and 2015.

Besides data analysis on air pollution, the report also carries an interactive website on the issue highlighting that 92% of the world’s population lives in the areas with unhealthy air.

“We are seeing increasing air pollution problems worldwide, and this new report and website details why that air pollution is a major contributor to early death,” said Dan Greenbaum, President of the Health Effects Institute (HEI), the global research institute that designed and implemented the study.

He said, “The trends we report show that we have seen progress in some parts of the world – but serious challenges remain.”

The State of Global Air 2017 is the first of a new series of annual reports and accompanying interactive website, designed and implemented by the Health Effects Institute in cooperation with the Institute of Health Metrics and Evaluation (IHME) at the University of Washington and the University of British Columbia.

The IHME is an independent population health research center that publishes the annual Global Burden of Diseases — a systematic scientific effort to quantify the magnitude of health loss from all major diseases, injuries, and risk factors in populations across the world. Its results are published every year in The Lancet medical journal.

“Although there are many parts of the world where air pollution has grown worse, there has also been improvement in the US and Europe. The US Clean Air Act and actions by the European Commission have made substantial progress in reducing people exposed to PM pollution since 1990,” said a statement issued by the HEI.

Referring to the study, it said, “The US has experienced a reduction of about 27% in average annual population exposures to fine particulate matter with smaller declines in Europe. Yet some 88,000 Americans and 258,000 Europeans still face increased risks of dying early due to PM levels today”.

The report noted that the highest concentrations of combustion-related fine particulate matter were in South and Southeast Asia, China and Central and Western Sub-Saharan Africa in 2015 where household solid fuel use, coal-fired power plants, transportation, and open burning of agricultural and other wastes were among the most important contributors to outdoor air pollution.

“The Global Burden of Disease leads a growing worldwide consensus – among the WHO, World Bank, International Energy Agency and others – that air pollution poses a major global public health challenges,” said Bob O’Keefe, Vice President of HEI and Chair of Clean Air Asia.

He said, “Nowhere is that risk more evident than in the rapidly growing economies of Asia.”

The study finds that increasing exposure and a growing and aging population have meant that India now rivals China for among the highest air pollution health burdens in the world, with both countries facing some 1.1 million early deaths from air pollution in 2015.

It said the long-term exposure to fine particulate matter — the most significant element of air pollution — contributed to 4.2 million premature deaths and to a loss of 103 million healthy years of life in 2015, making air pollution the 5th highest cause of death among all health risks, including smoking, diet, and high blood pressure.

India has, however, always been sceptical of such reports. Though the government here did never deny the negative impact of air pollution on human healths, it preferred not to speak about numbers.

Even recently during Budget session of the Parliament, the government had on February 6 said that there was no conclusive data to link deaths exclusively with air pollution. It, however, admitted that the air pollution could be one of the triggering factors for respiratory ailments and diseases.

“There is no conclusive data available in the country to establish direct co-relationship of death exclusively with air pollution. Health effects of air pollution are synergistic manifestation of factors which include food habits, occupational habits, socio-economic status, medical history, immunity, heredity etc. of the individuals,” said the country’s environment minister Anil Madhav Dave.

Dave, in his written response to a Parliament question in Rajya Sabha, had said, “Air pollution could be one of the triggering factors for respiratory associated ailments and diseases.”

Tube ‘higher than driving’ for air pollution, study finds

Travelling on the Underground exposes commuters to more than eight times as much air pollution as those who drive to work, a university study has found.

Monitors worn by commuters found those who travelled on the Tube were exposed to 68mg of harmful pollutant PM10, whereas car drivers had 8.2mg.

The University of Surrey study found when train windows were open, commuters were exposed to more pollutants.

Drivers were not as exposed because cars filter the pollutants out.

But although drivers are not exposed to as many pollutants, the types given out by cars are more harmful than the ones found on the Underground.

‘Environmental injustice’

The study found PM levels were highest on trains on the Victoria and Northern lines, because they all had their windows open, heightening the effect of pollutants when going through tunnels.

The study did not include people who commute on foot or cycle.

The study also found:

• Passengers on the District Line in trains with closed windows were exposed to far lower concentrations of PM than those travelling on trains with open windows on the same line
• Bus commuters were exposed to an average of 38mg of PM10, roughly half as much as Tube passengers but five times as much as cars
• The morning commute has more pollutants than the afternoon and evening journeys
• Although car drivers were the least exposed, they caused the most pollutants.

Dr Prashant Kumar, who led the study, said: “We found that there is definitely an element of environmental injustice among those commuting in London, with those who create the most pollution having the least exposure to it.

“The relatively new airtight trains with closed windows showed a significant difference to the levels of particles people are exposed to over time, suggesting that operators should consider this aspect during any upgrade of Underground trains, along with the ways to improve ventilation in underground tunnels.”

Drop in roadside air pollutants in Hong Kong thanks to government measures

I refer to Natalie Siu Hoi-tung’s letter on pollution in Hong Kong (“Air pollution impact can’t be ignored [1]”, January 27).

We can’t agree more that air pollution must not be ignored. The government has been taking action to improve air quality.

Locally, we have capped the emissions of power plants via statutory technical memorandums (TM) since 2008 and have been progressively tightening the caps. Since 2014, we have implemented an incentive-cum-regulatory scheme to progressively phase out 82,000 pre-Euro IV diesel commercial vehicles by the end of 2019.

We have also deployed remote sensors to strengthen emission control for petrol and liquefied petroleum gas vehicles.

In July 2015, Hong Kong became the first Asian city to mandate ocean-going vessels at berth to switch to low-sulphur fuel. A new regulation was introduced in June 2015 requiring newly imported non-road mobile machinery to comply with statutory emission standards.

Regionally, we have been collaborating with the mainland authorities to reduce emissions in the whole Pearl River Delta region. Emission reduction targets have been set for key air pollutants for 2015 and 2020.

Joint efforts have been made in various scientific studies/programmes, for example, the Guangdong-Hong Kong-Macau Joint Regional PM2.5 Study, which will help provide a scientific base in formulating policies to alleviate regional air pollution.

The above measures have borne fruit. From 2012 to 2016, our roadside and ambient air pollutants have dropped by up to 30 per cent and 21 per cent, respectively, while the ambient level of ozone has seen a slight decline of 3 per cent. However, amid the improvement trends, there are still episodes of high pollution when pollutants are transported from the delta region under unfavourable meteorological conditions. Hence, we have to continue our efforts to improve air quality.

We will continue to review the emission caps under the TM for power plants and we are preparing to tighten the emission standards for newly registered vehicles to Euro VI.

We will collaborate with the mainland authorities to set up a domestic emission control area in the Pearl River Delta waters in 2019, such that all vessels in the area will have to use low-sulphur fuel. Furthermore, we have embarked on a review of the air quality objectives (AQOs) to identify new practicable air quality improvement measures and assess the scope of tightening the AQOs made possible by their implementation. The review will be completed next year.

Climate Science Denier Myron Ebell Explains How the Trump Team Will Gut the EPA, Abandon the Paris Agreement

https://www.desmogblog.com/2017/01/31/myron-ebell-epa-transition-how-trump-gut-epa-abandon-paris-agreement

As senators get set to vote Wednesday on the confirmation of President Donald Trump’s nominee to run the EPA, the man who was charged with leading the Environmental Protection Agency’s transition team gave some clues as to how it might be run.

Myron Ebell is one of the country’s most prominent climate science deniers, is the Director of Energy and Environment at the Competitive Enterprise Institute (CEI), and until inauguration day was leading the EPA transition team at the behest of the then president-elect.

At a press event in London on Monday, attended and covered by DeSmog UK’s Mat Hope, Ebell admitted that he had never actually spoken to Trump, and that he was recruited to the transition team by New Jersey Governor Chris Christie.

What did Ebell’s transition team actually do?

“We did produce an action plan and an advisory document,” he said, but refused to discuss the contents of the “confidential” document. Coincidentally, in December, the CEI released a set of policy proposals called “Free to Prosper: A Pro-growth agenda for the 155th Congress,” which included a 26-page chapter on energy and the environment, though there is no way of knowing for sure if there is any overlap between the CEI proposal and Ebell’s action plan.

Although Ebell is no longer involved with the administration in any way, he made bold predictions and spoke confidently about how the Trump team would work to dismantle the EPA and pull out of the Paris Agreement, while finding plenty of time to bash the “climate industrial complex” and deny the consensus of climate scientists.

“The people of America have rejected the ‘expertariat’ about one thing after another including climate policy… climate scientists are in this for the glamour and the fame.”

“If we’re going to have some warming it should have started… it has been vastly exaggerated.”

Ebell indicated that Trump’s trust in Steve Bannon, the controversial former manager of Breitbart News who is now one of Trump’s closest advisors, was proof enough that Trump’s administration would take a torch to international climate action.

When pressed by reporters on the Paris Agreement, who brought up the fact that Secretary of State nominee Rex Tillerson said in his confirmation hearing that “it’s important that the U.S. maintains its seat at the table,” Ebell seemed confident that Tillerson wouldn’t get his way. “If Rex Tillerson disagrees with the president — who will win that? The president was elected and Rex Tillerson was appointed. I’d say the president was odds on to win.”

He also said that even if the U.S. wasn’t able to ditch the Paris Agreement immediately, the “cleanest” way to abandon the deal would be to “withdraw from the framework convention” entirely. Ebell was referring to the United Nations Framework Convention on Climate Change (UNFCCC), the body that holds the annual climate conferences and serves as the overarching body under which all international climate diplomacy is conducted.

Speaking specifically about the EPA, Ebell suggested that after Pruitt is confirmed, the agency will make a priority of stripping “harmful” air and water pollution regulations, and that the web of climate-related rules and actions would be systematically dismantled. Of the Climate Action Plan in particular, Ebell said, “There are numerous grounds that it should be undone and I hope that it will be undone.”

Ebell did not mention, however, that the EPA’s climate regulations stem from a 2007 Supreme Court ruling that held that greenhouse gases are air pollutants that should be covered by the Clean Air Act.

Ebell was speaking as a man no longer serving in the administration, as he resigned when Trump took office and presumably wasn’t asked to stay on board to lead the “beachhead” teams that are now lining the agency up for Pruitt’s likely arrival.

Some are speculating that Ebell’s move away is a sign that the Trump team is shifting away from the extreme climate deniers of the far right, and replacing them with personnel, like Tillerson, who at least publicly acknowledge the existence of manmade climate change. Regardless, it will be critical to track the early actions of the EPA after Pruitt presumably takes the helm, to see how they align with proposals that CEI put forth in December. For his part, Ebell is back at the fossil fuel industry–funded CEI full time.

The surprising link between air pollution and Alzheimer’s disease

http://www.latimes.com/science/sciencenow/la-sci-sn-air-pollution-alzheimers-20170131-story.html

With environmental regulations expected to come under heavy fire from the Trump administration, new research offers powerful evidence of a link between air pollution and dementia risk.

For older women, breathing air that is heavily polluted by vehicle exhaust and other sources of fine particulates nearly doubles the likelihood of developing dementia, finds a study published Tuesday. And the cognitive effects of air pollution are dramatically more pronounced in women who carry a genetic variant, known as APOE-e4, which puts them at higher risk for developing Alzheimer’s disease.

In a nationwide study that tracked the cognitive health of women between the ages of 65 and 79 for 10 years, those who had the APOE-e4 variant were nearly three times more likely to develop dementia if they were exposed to high levels of air pollution than APOE-e4 carriers who were not.

Among carriers of that gene, older women exposed to heavy air pollution were close to four times likelier than those who breathed mostly clean air to develop “global cognitive decline” — a measurable loss of memory and reasoning skills short of dementia.

While scientists have long tallied the health costs of air pollution in asthma, lung disease and cardiovascular disease, the impact of air pollutants on brain health has only begun to come to light. This study gleans new insights into how, and how powerfully, a key component of urban smog scrambles the aging brain.

Published Tuesday in the journal Translational Psychiatry, the research looks at a large population of American women, at lab mice, and at brain tissue in petri dishes to establish a link between serious cognitive decline and the very fine particles of pollution emitted by motor vehicles, power plants and the burning of biomass products such as wood.

All three of these biomedical research methods suggest that exposure to high levels of fine air pollutants increases both dementia’s classic behavioral signs of disorientation and memory loss as well as its less obvious hallmarks. These include amyloid beta protein clumps in the brain and the die-off of cells in the brain’s hippocampus, a key center for memory formation.

Using air pollution standards set by the U.S. Environmental Protection Agency, researchers found significant differences on all those measures between those who breathed clean air and those exposed to pollution levels deemed unsafe.

In lab mice, breathing air collected over the 10 Freeway in Los Angeles led to brain concentrations of amyloid protein that were more dense and more likely to form dangerous clumps than breathing air that satisfied EPA standards before 2012. When lab mice were bred with a strong predisposition to develop dementia and its hallmarks, the brain differences between pollution-breathing animals and those that breathed clean air were starker.

In 2011, a study in the journal Lancet found that those who lived close to densely trafficked roads were at a far higher risk of stroke and dementia than those who lived farther away. A year later, a team led by Alzheimer’s disease researcher Dr. Samuel Gandy at Mt. Sinai in New York first established that air pollutants induced inflammation, cell death and the buildup of amyloid protein in the brains of mice.

The new study extends those findings.

Authored by geriatric and environmental health specialists at USC, the new study estimates that before the EPA set new air pollution standards in 2012, some 21% of new cases of dementia and of accelerated cognitive decline could likely have been attributed to air pollution.

There is potential legal significance to the researchers’ finding that women (and mice) who carried a genetic predisposition to developing Alzheimer’s disease were far more sensitive to air pollution’s effects. In devising pollution standards, the EPA is currently required to consider their health impact on “vulnerable populations.” The agency is also required to use its regulatory authority to take steps to protect those populations.

Air pollution has been declining steadily since the EPA promulgated new standards in 2012. But Dr. Jiu-Chiuan Chen, an environmental health specialist at USC’s Keck School of Medicine and the study’s senior author, said it’s not clear that even current standards are safe for aging brains, or for brains that are genetically vulnerable to Alzheimer’s.

The Trump administration has signaled it will look to scrap or substantially rewrite Obama administration regulations that tightened emissions from power plants and established tougher fuel efficiency standards for cars in an effort to curb climate change and reduce air pollution.

“If people in the current administration are trying to reduce the cost of treating diseases, including dementia, then they should know that relaxing the Clean Air Act regulations will do the opposite,” Chen said.

Waste management problems are getting worse in Hong Kong

Rarely has an organisation performed as miserably, every year, as the Environmental Protection Department in its waste management programme.

Its failure was highlighted in reports by the Audit Commission and the Legislative Council’s Public Accounts Committee last year. Predictably, the department’s latest waste management report, for 2015, is no different.

Its two major targets have moved in the wrong direction five years in a row – the amount of waste per person disposed daily increased, while the waste recovery rate decreased. From 2014 to 2015, waste disposed went up (from 1.35 to 1.39kg), while waste recovered went down (from 36.5 to 35.4 per cent). That’s the worst performance in a decade.

In the Environment Bureau’s waste-management blueprint issued in 2013, the objective for the amount of waste per person disposed daily was set at 1kg by 2017 and 0.8kg by 2022. The recovery rate was to be 55 per cent by 2022.

Secretary for the Environment Wong Kam-sing has talked up the blueprint for the past two years. But at a January 17 press conference, he was mum about waste management performance, except for an 8 per cent decrease in food waste, which is just 30 per cent of total domestic waste.

I have long argued that the blueprint’s waste disposal and recovery targets are unattainable.

Wong and his department seem incapable of grasping the simple equation governing waste management: waste disposed is equal to waste generated less waste recovered.

Imposing a waste-charging scheme cannot lower significantly the amount of waste disposed, unless there’s a commensurate increase in the amount of waste recovered.

And the waste recovery rate cannot increase much without waste separation at source.

Wong cited the success of South Korea and Taipei in reducing waste disposed by imposing waste charging. He omitted the crucial factor in their success: waste separation at source is required by law.

Waste-recovery companies in Hong Kong have to sell paper, plastic and metal to the mainland at market prices, which cannot be controlled by the Environment Bureau.

This means the current 36 per cent waste recovery rate cannot realistically increase to 55 per cent, which is the rate achieved by countries that successfully manage their waste.

At its 36 per cent waste recovery rate, Hong Kong needs to reduce waste generation by 40 per cent from the current level to achieve the 0.8kg average amount of waste per person disposed daily by 2022. In their dreams.
