A new survey in Hong Kong has found that one in five residents is considering leaving because of the city’s poor air quality.
The survey, by the Civic Exchange think tank, has again raised fears over Hong Kong’s competitiveness.
It found that over a million residents have thought of leaving, including 500,000 who are “seriously considering or already planning to move”.
They include top earners and highly educated workers, raising questions over Hong Kong’s ability to attract and retain top talent.
Air pollution in parts of Hong Kong last year reached its highest level since records began.
