THE London Assembly has warned Boris Johnson that his plans for improving air quality is “missing key data” to make them effective. Important information has not been included, it is pointed out

MEMBERS of the London Assembly have warned Boris Johnson that his plans for improving air quality is "missing key data" and needs more work to make them effective.

Important information showing the effectiveness, timescale and how his Draft Strategy is to be paid for has not been included, the Assembly's environment committee points out.

The next draft outline must include health benefits, costs, timescales which recognise urgency, projections for concentrations of pollution and what would happen without such a plan, the committee insisted.

"It is essential the Mayor gets his strategy right," said environment chair Murad Qureshi. "Poor air quality can contribute to serious ill-health and premature deaths.

"Our suggestions will improve air quality, reduce the harm done by air pollution and give the strategy some credibility."

The response to the Environment committee's own air quality report

published in May is being considered for formal agreement on Friday (Dec 4).
