UK, China experts come together to battle Beijing's smog

Researchers at the University of Birmingham have underlined the urgent need for Chinese megacities to identify sources that contribute to the lingering air pollution.

With a total investment of £2.6 million ($3.2 million), researchers from China and the UK launched a project last year to address air pollution sources in Beijing.

The project was led by seven UK universities, along with the Chinese Academy of Sciences and Tsinghua University.
