Boris Johnson has yet to show how he will keep his promise to make London the greenest city in the world after his first 100 days as Mayor of London, Friends of the Earth said today.

Despite promising to make London a world leader in tackling climate change, and cut the capital's carbon dioxide emissions by 60 per cent by 2025, Mr Johnson has not come forward with a programme for achieving this.

More alarmingly, although he has made encouraging progress in some areas, the new Mayor is adopting or considering a number of policies that are likely to increase London's carbon footprint. These include:

Scrapping plans to introduce a climate change-related congestion charge and re-opening the public consultation on the C-charge zone's western extension;

Endorsing a 50 per cent increase in flights from London city airport and considering the scope for a new airport in the Thames Estuary;

Support for an extra river crossing downstream from Tower Bridge to ease traffic congestion - - which could lead to a rise in the number of vehicles on London's roads if this was a road crossing.

Friends of the Earth's London campaigns coordinator, Jenny Bates, said:

"After 100 days Boris Johnson has yet to show how he will keep his promise to make London the world's greenest capital.

"He has made progress in some areas - but this has been undermined by transport policies that will lead to more traffic, more flights and more climate-changing carbon dioxide emissions.

"There is still time to act. In his next 100 days Boris Johnson must show that the Conservative party is serious about the environment and set out how to make London a world leader in developing a low-carbon, green future."

Friends of the Earth is calling on Boris Johnson to:

Ensure that his first Budget prioritises action on climate change;

Set out a clear set strategy for delivering his pledge to cut the capital's carbon dioxide emissions by 60 per cent by 2025 (based on 1990 levels)

Oppose the expansion of air travel - from increased flights, airport expansion on new airports - across London and push for alternatives such as improved fast rail links;

Reject plans for any new road bridges across the Thames - and develop policies to cut traffic such as better public transport and cycling facilities.
