Dear Mr Middleton,

Thank you for your mail. We would like to provide our responses on your observations made at the end of your mail :

Replacement of Franchised Bus
All franchised bus companies required to operate their franchised bus services with buses under the age of 18, and have been replacing their serving buses accordingly.  This arrangement has taken account of the maintenance, operational and financial capability of the bus operators.

Franchised bus companies have to submit annually to the Transport Department (TD) their Forward Planning Programmes for the next five years, including programmes for purchasing new buses and retirement of old buses.  It is estimated that about 2,300 serving franchised buses of which about 700 belong to CTB, including all pre-Euro and Euro I and some Euro II buses, will retire by 2015.

Given that it would take time for all the Euro II and III buses will be replaced, the Government is looking into various cost-effective options to improve roadside emissions, such as retrofitting diesel particulate filters (to reduce particulate emissions) on Euro II and III buses and to commit a trial on retrofit of Selective Catalytic Reduction devices to reduce the emissions of Euro II and III buses to the emission level of Euro IV buses.  Further, in order to promote wider use of environment friendly buses, the Government has added a requirement in all franchises with the bus companies that when setting specifications for acquisition of new buses, they are required, as far as practicable, to adopt the latest commercially available and proven technologies to reduce exhaust and noise emissions.

Return on Average Net Fixed Assets (ANFA)
For franchised bus operation in Hong Kong, the 9.7% rate of return on ANFA is not a “mandatory” nor “guaranteed” rate of return that the bus operators could enjoy, but is only the triggering point for sharing of return between bus operators and passengers.  If the bus operator achieves a return on ANFA above 9.7%, half of the excess over 9.7% will be shared with passengers by providing fare concession or stabilising bus fare.  On the other hand, if the return of the bus operator falls below 9.7%, the shortfall cannot be offset against the fare concession/fare stabilisation obligation.

Disposal / scrapping of buses
The profits on disposal of buses if any, are included as part of the bus operators’ return.  Moreover, the purchase and disposal of buses, as well as the overall bus fleet size, are monitored by TD in various ways.  The franchised bus operators could not sell buses at artificially low book values and then buy back refurbished buses at prevailing market rates.
Please rest assured that the Government will continue to work with the franchised bus companies to implement appropriate measures with a view to further reducing roadside air pollution.

Excess Rents Hong Kong Style: Citybus

As some of you know I am a bit of greenie and get pretty angried up about air pollution. HK’s air pollution is due to two things: regional air pollution, largely from Guangdong that Hong Kong can arguably do little about (the biodome idea was shot down) and roadside pollution principally caused by buses and trucks about which it could do a lot more. There is a great paper here from 2009 that outlines what HK could do about its air pollution, bus regulation is the best “bang for the buck” thing that HK could do with a 6.3 cost to benefit ratio. Paper here.

As buses are regulated utilities I thought I’d look into the financials of these businesses and the documents governing their concessions to see just what was causing them to be so slow to turn over their bus fleet – maybe fares are too low, or perhaps they face exceedingly high costs of some kind, leaving them limited extra cash to invest in newer, cleaner buses. Crazier things have happened though HK’s other utilities like Power Assets Holdings (formerly Hongkong Electric), CLP and Transport International Holdings (listed entity holding the Kowloon bus franchise) have pretty standard returns on equity that would not look out of place in most jurisdictions though Transport International seemed to be earning some fairly ridiculous returns from 98-03 and again in 04-05.

Well, as you can see here for the bus franchises owned by New World – Citybus in particular – that is most certainly not the case (numbers extracted from here). Citybus’ headline ROA numbers is way higher than their 9.7% mandated level and if you look into their depreciation accounting it is much higher.

You see, when you look at the concession agreement for Citybus (Transport Department link here) a few things jump out. Firstly, the depreciation of the buses is 15 years straight line to $1 – so the buses can be readily written down zero or close to it, which is funny because they are almost there – the bus fleet is about 12.5 years old now on average meaning there are a number of assets older than 15 years that are held at $1. Cute, though under ROA type regulation there is no free lunch: if you haven’t got any assets you aren’t entitled to any returns. That does not seem to be the case here – if you take their depreciation at face value Citybus is earning some major excess rents and the Transport Commissioner should explain why New World gets special treatment.

What is a much better representation of Citybus’ returns is when you ignore depreciation and look at cash capital expenditures net of proceeds from disposals. Net cash capex for these business is pretty close to zero – $4.5mm Hong Kong which is absurd when a new Euro V bus costs $3-4mm Hong Kong. So the cash return on book assets they making is close to 30-40% which is the sort of return you expect on a high risk mining venture, not a regulated utility in Hong Kong.

What is more, these disposals are a source of no doubt significant excess rents for New World. Here is how I would take advantage of the Transport Commissioner being asleep at the switch:

1) Get an ROA way above requirement due to aggressive depreciation accounting that is unassailable because its in the terms of your concession and thus protected by contract. Watch the Transport Commissioner do nothing. (we know this is happening from these accounts)

2) Sell older buses at artificially low book values as your regulated fares don’t take account of this in calculating your asset returns. Use proceeds to fund the bare basement capital expenditure you do. Net result: almost no cash capital expenditures.

3) When the concession comes up, buy back refurbished buses at prevailing market rates to ensure you have an asset base on which to earn fares. Claim that you are making a big investment when bidding for the concession.

4) At every available opportunity cry poor about oil prices.

Net-net: 20-30% cash returns for 10 years on government utility type risk.

What can I say? I’m clearly in the wrong game. The bigger question is why isn’t anyone doing anything about this, and why does Transport International not get to play at this game? Its numbers look pretty aggressive too (depreciation at ~900mm HKD, versus capex that looks lower) but Citybus is taking it to another level.

Anti-Hype in Lithium-ion Batteries Foretells Doom for Electric Cars | Alternative Energy Stocks

Anti-Hype in Lithium-ion Batteries Foretells Doom for Electric Cars

John Petersen

Despite billions of dollars in private investments and public subsidies,
lithium-ion battery technology has progressed at a snails pace for years
and battery developers have recently started to emphasize the importance of
baby steps. For the first time in memory, anti-hype is becoming a dominant
theme in stories about lithium-ion batteries.

Examples from this month include:
.An interview with Wards Auto where the business manager of the DOE’s
Kentucky-Argonne Battery Manufacturing Research and Development Center
explained that it takes about ten years to put a battery innovation into
production and all of today’s EVs are powered by technologies that were
developed at least a decade ago.
.An article from National Defense which predicts that lithium-ion battery
research will soon hit a brick wall because batteries can only be as small
and lightweight as their materials allow and immutable laws of physics and
chemistry limit the number of electrons that can be stored in a given mass
of battery material.
.An article in Nature that discussed ways nanotechnology can improve
battery performance by increasing surface area, but took pains to explain
that nano-materials must be produced in carefully controlled environments
and the high cost of manufacturing nano-materials usually outweighs the
benefits derived from using them.
.An article in Design News that focused on the harsh reality that battery
development is hard, slow work because batteries require a wide variety of
costly materials to work together as a system; there are limitless ways
that things can go wrong; and throwing loads of money at research can’t
make progress happen overnight.
.An article in Waste Management World that explains the complex technical
and economic challenges that must be overcome before lithium-ion battery
recycling can progress beyond a few pilot plants and become a
cost-effective industrial reality, as opposed to a hopium-laced talking
point.
.An article in the MIT Technology Review that reads like a premature
obituary as it discusses the triumphs and tragedies at A123 Systems (AONE)
and their ongoing search for strategic alternatives.

My personal favorite is a strategy memo from the National Alliance for
Advanced Technology Batteries that focuses on the problems at A123 Systems
and the failures of Ener1 and International Battery. It’s classic spin
control that ultimately blames the debacle on government policy. Since the
irony is so rich, I’ll annotate the last three paragraphs by highlighting
text that I find particularly entertaining in bold type and adding some
observations [in brackets].

“If criticism intensifies, which is likely, it will be important to
communicate an important point: Government funding of new energy
technologies is meant to support those technologies, not the companies that
develop them [or the investors who bought the hype that’s part and parcel
of government support]. The failures of Ener1 and International Battery,
and the troubles of A123 Systems, are business failures, not technology
failures. Companies come and go. Corporate assets get bought, sold and
reorganized [while investors lose their shirts]. None of that should matter
to taxpayers. What should matter is whether the technologies that A123 and
Ener1 owned at the time they received their grants has been advanced and
pushed closer to commercialization [while politicians promised
cost-effective products]. Indications in both cases are that they have been
[but unsubsidized demand hasn’t materialized].

If the FOA-26 program can be criticized for anything it is that the program
focused on funding immediate deployment of advanced automotive battery
technology rather than its longer term development. Many pointed that out
at the time [and we were lambasted as neo-luddites]. The [entirely
predictable] problems at A123 Systems and the failures of Ener1 and
International Battery are powerful testimony to the fact that the market
for that technology in 2009 was critically immature [just like the
underlying technology]. A better use of the funds would clearly have been
investing them in the development of new, next-generation battery
technologies that could facilitate the development of a market for advanced
automotive batteries in the future rather than cater to one that did not
fully exist.

In fairness to the Department of Energy, the emphasis on immediate
deployment and “getting shovels in the ground” was a political directive
motivated by a critical economic crisis, not a considered policy decision.
As a consequence, DOE funding of advanced battery technology over the past
three years has not been as efficient as it might have been. But that is
not to say that it has been a failure. Steady progress on increasing energy
density, decreasing battery cost and improving battery system management
continues to be made [at a snail’s pace]. The market we hoped for in 2009
is not here yet and some of the original players in the market may not make
it to the finish. But that market is substantially closer than it was three
years ago, and by that fact the success or failure of the FOA-26 program is
more properly judged.”

The core message of this new anti-hype campaign is clear. The promised
improvements in lithium-ion battery technology have not materialized and
they’re not likely to evolve from existing technology and architecture. We
may see a doubling of energy density over the next decade, but the six- to
seven-fold gains that Energy Secretary Chu has called for are not possible
with current technology. The dream of quantum leaps in performance
accompanied by precipitous cost reductions is not in the cards, or for that
matter on the horizon. Breathless promises of cost-effective electric cars
that will clear the air and deliver us from the tyranny of oil dictators
are snake oil cures that will enrich the hucksters for a time, but end in
tar, feathers and a ride out of town on a rail.

Battery mythology developed for the sole purpose of supporting electric car
mythology. Battery developers tried mightily and failed. Now battery
developers are seeking shelter from the backlash that inevitably comes back
to haunt companies and industries that promise more than they can deliver.
The next dominoes are companies like Tesla Motors (TSLA) that can’t
possibly build cost-effective electric vehicles without better and cheaper
batteries. Tesla may survive for a time by making toys for the
ideologically committed and mathematically challenged rich, but the
congenital birth defect that’s doomed every generation of electric cars to
the scrap heap remains.

The electric car industry can’t survive without a thriving and profitable
battery industry that can make products that meet or exceed expectations.
The battery industry is on record saying they can’t meet the ambitious
goals they embraced in the recent past. Things might change in my lifetime,
but the change is not going to happen in the next decade. Meanwhile the
real auto industry is digging into its toolbox and rapidly implementing
technologies that weren’t cost-effective in another economic era but are
today.

Three die as electric taxi explodes

Concerns are raised about possible fatal design flaw in green vehicles after deadly collision in Shenzhen
Choi Chi-yuk
May 28, 2012

A fatal road accident in Shenzhen at the weekend has raised concerns about the safety of electric cars developed on the mainland amid an ongoing central government push for them to be more widely used.

At about 3am on Saturday, a speeding sports car rear-ended a BYD E6 electric taxi, causing the cab to catch fire, killing the driver and two passengers, according to The Southern Metropolis News.

Police said the driver of the sports car had been drinking. He fled the scene with three young women in the car, but turned himself in yesterday.

One witness, another taxi driver, said: “The sports car must have been driving at between 150 and 200km/h when it passed me. I was driving at more than 90km/h.” He added that he saw the BYD taxi in flames on the roadside a few minutes later.

Numerous calls to BYD for comment went unanswered yesterday.

The electric taxi and its occupants were incinerated, the report said.

A member of the rescue team said that, based on the wreckage, it was possible that an explosion occurred in the electric car.

The accident raised concerns, largely online, over the safety of electric cars, the report added.

Lo Kok-keung, an engineer with the Department of Mechanical Engineering at Hong Kong Polytechnic University, said that a fully charged lithium battery could explode in a serious crash.

“The crash could result in a short circuit, which, in turn, could make the battery hot and eventually explode within a matter of seconds,” Lo said. “This is the major hidden danger of electric cars that doesn’t exist in vehicles that consume petrol.”

With support from the central government, BYD has poured billions of yuan into developing its electric vehicles, offering tens of thousands of yuan in rebates for buyers. The Shenzhen government has also spared no effort in building new charging stations.

Shares in the Hong Kong-listed carmaker soared in 2009 upon word of the environmentally friendly push, and after the high-profile backing of US billionaire Warren Buffett. But the stock plunged last year on poor sales.

About 300 BYD E6 taxis and 200 buses, all of which run solely on electricity, are operating on the streets of Shenzhen.

Lo suggested that makers of electric cars install circuit breakers on each battery, to help avoid future explosions in accidents. “The safety of electric vehicles could certainly be raised significantly by doing so,” he said.

In a move to become China’s electric vehicle capital, Shenzhen in March set a goal to replace more than 50 per cent of the city’s internal combustion engine buses with electric or hybrid models by 2015.

Shenzhen mayor Xu Qin said during the current National People’s Congress in Beijing that within three years the city would ban all vehicles that failed to meet the country’s advanced emission standards. Xu said 3,000 electric or hybrid vehicles were put into use in Shenzhen last year, and 2,000 were planned for this year.

In Shenzhen, every electric bus put on the road has received a one million yuan (HK$1.22 million) subsidy since 2010, half from the central government and half from Shenzhen’s. Subsidies for hybrid buses were increased from 300,000 to 600,000 yuan last year.

Hydrogen Fuelling Station (May 2012) – the future of vehicular transport is hydrogen – whose emissions are —— water

Meanwhile backward Hong Kong plays with electric buses that need to be charged every 10 kms and cannot go up hills with the aircon on.
Air Products’ hydrogen fuelling station in Freiburg, where the vehicles stopped to refuel on route to Monte Carlo.
Air Products’ Hydrogen Fuelling Station Helps Fuel Cell Cars Drive from Oslo to Monte Carlo

The Zero Emissions Resource Organisation (ZERO) based in Oslo, Norway has driven two Hyundai iX35 fuel cell electric vehicles (FCEV) from Oslo to Monte Carlo, using only existing hydrogen filling stations for refuelling. On the vehicle’s journey from Gaustad in Oslo to Monte Carlo, they stopped at fuelling stations in Denmark, Germany and France including Air Products new Freiburg hydrogen fuelling station.

Referring to the solar hydrogen station in Freiburg, Marius Bornstein, technical adviser on hydrogen at ZERO said, “When the cars go on pure solar energy, it is hardly possible to imagine a more environmentally friendly way to travel.”

“One of the challenges sometimes leveled at the commercial introduction of fuel cell technology is limited infrastructure,” commented Diana Raine, business manager of Hydrogen Energy Solutions. “However this trip is a great way of showing the significant hydrogen infrastructure advancements being made across Europe.”

The Hyundai iX35 was chosen for its range, being able to cover 500 km on a tank of hydrogen. In what could be a record setting distance the vehicles covered 2,260 km in the five days en-route to Monte Carlo with no support vehicles or mobile refuellers.

“This has never been done before, and why did we do it? To show that it is possible to drive emission free from Oslo and throughout Europe,” Marius Bornstein added.

Air Products’ Hydrogen Station Dedicated and Fueling Flint MTA Fuel Cell Bus

The Air Products hydrogen fueling station in Flint, Michigan was officially dedicated and is filling the Flint Mass Transportation Authority’s (MTA) hydrogen fuel cell powered bus now in service for riders, as the Flint MTA officially opened its alternative fuel facility today. Air Products, theleader in hydrogen fueling technology, constructed and completed the fueling station and infrastructure as part of MTA’s alternative fuels test program.

“We have had successful involvement and taken a leadership position in hydrogen fueling for mass transit. We congratulate Flint’s MTA for seeking this zero emission form of transportation and participating in the increasing trend in the evolution of mass transit that we see nationally,”said Bob Kelly, business development manager for Hydrogen Energy Systems at Air Products. Kelly also noted this Flint hydrogen fueling station is not the company’s first in the state as it has, and continues, to provide hydrogen fueling and infrastructure for several of the automobile companies in Michigan.

At the site, Air Products is supplying its hydrogen compression, storage and dispensing technology to fuel the bus with hydrogen produced from a PEM (proton exchange membrane) electrolyzer provided by Proton OnSite. Details on Air Products’ portfolio of hydrogen fueling station technologies are provided at www.airproducts.com/h2energy.

Air Products has a proven global record of providing reliable fueling systems in working with themass transit industry. Some of this work includes: a mobile hydrogen fueling system for fuel cell powered buses on the Alameda-Contra Costa Transit District bus system in the San Francisco Bay Area in California (2011, 2010); commissioning a fueling station in London to fuel a fleet of five hydrogen buses as part of the Transport for London Project (2010), and the same station will fuel the first fleet of London hydrogen taxis planned for 2012; and fueling a fleet of more than 50 hydrogen fuel cell shuttle-bus vehicles that transported athletes and government officials at the Asian Games and Asian Para Games in Guangzhou City, China (2010). The China project was similar to Air Products filling hydrogen buses at a fueling station in the Beijing Hydrogen Park during the 2008 Beijing Olympic Games, which marked the first demonstration project for new-energy vehicles in China.

Cops run into trouble with electric bikes

HK Standard

Staff reporter

Monday, May 21, 2012

The police plan to use electric vehicles for patrols has run into trouble with the frequent breakdown of 12 imported electric motorcycles.

Three of them spent almost as much time in the repair shop as on the road.

Police spent HK$1.2 million on the 12 electric motorcycles between 2008 and 2009.

They were under maintenance for 143 days each year on average. This means they function normally for around seven months a year.

Three worked for less than six months a year while one, imported in April 2008, was on the road less than five months a year.

Police said most of the maintenance work was related to battery issues, reported Sing Tao Daily, sister newspaper of The Standard.

Meanwhile, the government has introduced 21 electric cars costing HK$9.5 million to various departments, part of Chief Executive Donald Tsang Yam-kuen’s green policy initiative to improve air quality in the city.

However, it was found that these electric cars travel only an average of 936 kilometers per month, much less than other government vehicles.

One of the electric cars belonging to the Water Supplies Department travels only 393km per month on average and is idle 11 days a month.

The department said it realizes the vehicle is underused and has vowed to strengthen battery recharging devices to enhance its operation.

Green Power scientific research and conservation division head Cheng Luk-ki said the government has to explain to the public why the electric vehicles are not fully utilized.

The government could be using them merely for exhibition and promotional purposes, he said.

In his 2009 policy address, Tsang promoted the use of electric vehicles.

The Environment Bureau has been working with a number of electric vehicle manufacturers to boost use of the vehicles.

Tsang said he expects Hong Kong to rank second in Asia behind Japan in the use of electric vehicles.

Hong Kong’s KMB electric buses to hit the road next year

Clear the Air says: the obvious choice is to use hybrid buses that can run all day and need no charging stations ! better still hydrogen fuel cell buses – (Dream On !)

http://asiancorrespondent.com/81408/hong-kongs-kmb-electric-buses-to-hit-the-road-next-year/

Out with the old, in with the new.

As Hong Kong makes a fond farewell to its beloved vintage buses, new ones offer a hint of the future are fitting symbols of transition in a city well-known for transport efficiency.

Kowloon Motor Bus recently submitted a proposal to the Transport Department that would pave way for the first commercial operation of electric buses in the city. The new route 5M, afive-kilometer stretch between Ping Shek bus terminal in Kwun Tong, Eastern Kowloon and Eastern Road, near the old Kai Tak airport in Kowloon City, utilizes single-deck electric buses. Along its route are two charging stations which allows these buses to operate without disruption. Single-journey fare is pegged at about HK$3 (US$0.38).

Although these zero emission buses are more desirable to run at Hong Kong’s polluted roadsides, they are more expensive to procure than their diesel counterparts. Yet, KMB is gracious enough to keep fares in line with other similar routes on conventional double-decker buses.

The bus was developed by a Zhejiang, China-based coach maker, in cooperation with German bus manufacturer Neoplan. After a full charge, it can run up to 10 kilometers and sustain a continuous supply of air conditioning for up to an hour. This is better than another prototype developed by a joint venture between Volvo and Shanghai Automotive Industry Corporation, which can support uninterrupted operation for only 3.5 kilometers.

While the adoption of electric buses isn’t as quickly as we hoped, this development still helps the objective of reducing air pollution, and enable Hong Kong to join early adopters such as Canada, Spain and Japan.

Public short-changed by government’s decision to extend three bus franchises

SCMP

Clear the Air says: there are more than 6,000 franchised registered buses in Hong Kong. The franchise holders pay no import or first registration tax and pay no tax on diesel fuel.

Existing franchise agreements already state that any replacement buses must be of the Best Available Current Technology (which means Euro V diesel, hybrid electric, hydrogen fuel cell or electric vehicle ) and that buses must be retired after a certain age so the replacement of only 700 buses  is minimalist and too much in favour of the franchise holders.

However the Government has a magic wand that remains locked in Donald Tsang’s home safe for fear of perhaps annoying Sun Hung Kai (owners of KMB) or  his brother Tsang Yam Pui who is a director of Citybus and New World First Bus – with the magic wand the Government could mandate ‘Clean Air Zones’ for Nathan Road, Causeway Bay and Central main arteries.

Only Euro 5 , hybrid electric and electric buses would be allowed to enter a ‘Clean Air Zone’.  The franchise owners would thereby have to comply and spit the dummy.

A sensible Government would have large bus termini outside of these areas connecting at no additional charge to electric or hybrid shuttles that ply the ‘Clean Air Zones’, instead of having nose to tail buses aka Mobile Painted Advertising Billboards, plying and congesting the main arteries 90% empty for 80% of the day.  Then of course there are the old commercial diesel trucks and the lack of any Emissions Control Area for shipping which contributes 31% of particulates and ¼ of the  NOx and SO2 in our air.

Sadly sense is lacking in the current administration and roadside pollution has increased markedly during their tenure – they seem not to care and are seemingly too busy jetting off to cleaner shores or hitching rides on a tobacco tycoon’s yacht or abusing the public purse with extravagance .

CY Leung is being handed a bag of  bones to resolve.

May 02, 2012
It comes as no surprise that the public is unimpressed by the government’s decision to extend the franchise for three bus companies. Under the deal, New World First Bus, Citybus and Long Win have been given the right to operate for another 10 years. In return they have pledged more service commitments and fare concessions on some routes.

The public can be excused for questioning whether this is the best deal the government could get. The concessions appear to be substantial at first glance. These include replacing 700 polluting vehicles by 2016. There will be more inter-change discounts and reduced fares for different sections.

These are certainly welcome changes. But they do not go far enough. For instance, the fare concessions will only benefit some 8,000 passengers, out of millions carried by the fleet every day. The move to take polluting buses off the road appears to be a cosmetic gesture, since many vehicles, according to activists, are due to retire by 2018 anyway. The deal falls short of public expectations.

The government could have pushed the companies to do more when negotiating the franchise renewal. It is disappointing that issues like buses running behind schedules, overlapped routes and the perception of the fare adjustments mechanism being unfair have not been resolved. Now that the franchise has been renewed, pushing for more would be difficult. Passengers will have to live with the service in the next 10 years. The opportunity to tackle the problems has been missed.

Renewing franchises of passenger service companies and utilities can only be justified for as long as the operator is committed to providing a good service. The termination of the franchise for China Motor Bus and Yau Ma Tei ferry in 1998 is a case in point. There is no evidence to suggest that the three bus companies do not deserve renewal. But franchises give companies the exclusive right to operate and make money. It is only fair that they strive to do more to satisfy public needs.

Establish low-emission zones in city

As David Akers-Jones points out, there are ways the government could facilitate the removal of dirty old buses from our roads (“Get rid of filthy buses with loans”, April 30).

The suggestion of bridging loans to allow the bus companies to retire these clunkers a few years early would be a simple, low-cost solution. But the often cited figure of buses accounting for up to 40 per cent of roadside pollution is slightly erroneous as they actually only account for 6 per cent of respirable suspended particulates across Hong Kong.

The higher figure was a Transport Department estimate of the possible contribution to roadside pollution in busy commuting corridors at peak times – essentially the worst-case scenario of the most number of buses on the road when the pavements are full of people going to work.

If the department actually wanted to reduce roadside pollution there is an even cheaper or near-zero cost solution to reduce the effect of dirty buses.

Simply make these busy commuter roads and congested tunnels low-emissions zones at peak times. Not only would this ensure bus firms use the latest Euro engine vehicles, where the most benefit can be derived, it would also stop old commercial diesel vehicles clogging up and polluting these roads during the rush hour.

People still misusing recycle bins

In the report, “Give us more bins to boost recycling” (May 2), you say that “once a recycling bin is contaminated with non-recyclable rubbish, it effectively becomes a conventional bin that will end up in a landfill site”.

But why does it become contaminated?

A few years ago, I had recycle bins installed in my village.

To this day, whenever I take my paper, plastic and metal out, the bins are either filled with ordinary rubbish or the wrong items are in the wrong bins.

On a recent trip, the paper bin was filled with styrofoam lunch boxes with half-eaten food spilling out. I can’t decide whether people are lazy, ignorant or just wilfully obtuse.

The bins are clearly labelled and colour coded; you’d think people would have figured out how they work by now.

Follow fine example set by Shenzhen

Clear the Air says: the actual way forward is to use hybrid electric buses as used in London. These have the power to climb hills and use a small Euro V engine to charge the batteries as the bus runs as well as

charging whenever the brakes are applied.

SCMP – Follow fine example set by Shenzhen 30 April 2012

Hong Kong should take full advantage of the scheme in Shenzhen, where more than 50 per cent of the city’s combustion-engine buses are to be replaced with electric or hybrid ones by 2015.

One way in which the Hong Kong government can ensure that air pollution levels go down is by reducing pollutants emitted by cars or public transport operators.

The administration could follow the example set by Shenzhen and massively cut emissions of carbon dioxide.

At least with electric buses we would have zero emissions of PM2.5 [health-threatening fine suspended particulates].

Air pollution has adversely affected the quality of life of citizens and the economy.

It poses a grave threat to public health.

For all our sakes, it is time to take action and adopt a scheme similar to the one in Shenzhen.
