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."

Campaign group, Clean Air in London claims pollution is causing all of the top four male death categoriesRead the full story ›
In London and across Europe, air pollution is killing more than ten times the number of people dying from road traffic accidents.
The known health effects of air pollution have rocketed in recent years with the World Health Organisation classifying outdoor air pollution as carcinogenic to humans in October 2013 as it did smoking in February 1985.
At its simplest, in public health terms, 'invisible' air pollution is where smoking was thirty years ago in terms of the scale and certainty of the risks and the lack of public understanding of them.
The huge variation in death rates for different death categories across boroughs may raise serious questions about inequalities and the competence and culpability of London authorities.
Health campaigners are urging the government to do more to tackle air pollution in the capital as new figures show it is a factor in thousands of deaths.
Clean Air London claims that air pollution is killing more then ten times the number of people who die from road traffic accidents.
Every year thousands of peoples' deaths in London are linked to pollution. Since 2008 the city's Low Emission Zone has been enforced to try to help make our air cleaner. Now, scientists from two universities claim that during the first three years of the scheme pollution levels didn't fall.
