The United States of America produces one quarter of the world's carbon dioxide emissions.
In this three-part series, Laura Trevelyan, the BBC's United Nations correspondent in New York, finds out how the US could retreat from its role as the biggest polluter on the planet.
Programme 1: The Addiction to Oil
Listen to the programme
Laura Trevelyan visits the New York Motor Show to report on moves among the big three US car makers to kick the oil habit and 'green' their industry.
Author of Lives Per Gallon, Terry Tamminen, who is also green advisor to California Governor Arnold Schwarzenegger, and Bob Semple of The New York Times talk about how vested interests killed off electric cars in California.
Laura considers viable alternative technologies and predicates a mobile but "carbon limited" future.
