The Mayor's measures include plans to ensure that by 2020 the vast majority of vehicles in the capital's centre during the working day emit low or zero emissions.
He has also suggested plans to introduce an Ultra Low Emissions Zone in central London.

The London Mayor Boris Johnson has said stories that he is planning to be Prime Minister should be "knocked on the head".
During an argument with the London Assembly Chair Jennette Arnold, he laughed off a suggestion that he was "being prime ministerial".
The Mayor said the level of dangerous particulates in the air has been reduced by 15% because of action on encouraging clean vehicles, walking and cycling. He also said he has introduced a plan to bring in an Ultra Low Emission Zone for vehicles in London by 2020.

When Boris Johnson was re-elected mayor ten months ago, he promised to dedicate himself to London and to Londoners. But today he's being accused of shirking that duty by devolving his power to his staff. There are complaints that he's not taking his job seriously. Simon Harris reports.
London mayor Boris Johnson is at the centre of a new row about whether he works hard enough. Opposition politicians on the London Assembly have accused him of abdicating responsibility for important decisions.
The mayor has changed the rules to give unelected officials a greater say at City Hall. He has to approve any decision which involves spending above £50,000 but the threshold is now being raised to £125,000. Labour's Len Duvall said: "Boris's attention seems to be increasingly elsewhere."
Boris Johnson has previously come under fire from his critics for accepting a £250,000 a year contract to write a weekly column for the Daily Telegraph. The mayor was speaking at a property conference on the French Riviera this lunchtime and was unavailable for comment.
