Air Pollution in the capital can lead to premature deaths of thousands of Londoners each year
You may never have thought that something as simple as the walk to school could affect your child's health - but the route they choose to take may actually be having a serious impact on their well being.
The Supreme Court has begun hearing a landmark case over claims the government is failing to meet EU pollution targets.
Martin Stew's been to see how taking a quiet route home could be a lifesaver.
A Supreme court ruling could mean the Government has to speed up its plans to deal with air pollution, just days after London was blanketed in smog.
The Government has been fighting legal action for four years over its failure to meet EU nitrogen dioxide levels.
High levels of air pollution are to hit central London today.
The warm weather is pulling hot air in from France, bringing dense smog with it.
Older people and those with asthma or lung problems are being urged to take extra care.
A report has been produced showing not enough is being done to meet carbon emission targets in London.
The London Assembly Environment Committee has produced a 'report card' and gives Mayor Boris Johnson a score of four out of ten.
Performance in the retrofitting of homes was one of the lowest, with a score of 3 out of 10.
The report recommends that more is done on local and low-carbon energy, especially solar, and on helping businesses to cut their energy bills.
"Frankly, the committee is disappointed with the progress being made on carbon reduction targets. The Mayor is missing targets on emissions from homes, decentralised energy generation and retrofitting workplaces, by big margins. The Mayor must try harder at these subjects, get more out of the government and give more help to boroughs. Transport emissions are fairly close to their 2015 target - but we urge Transport for London (TfL) - the capital's biggest energy consumer - to take proactive action and negotiate more vigorously for low-carbon energy. TfL could also generate more of its own electricity."
