The outspoken politician announced shortly before Christmas that he intended to reduce emissions substantially in London over the coming years.
Livingstone's proclamation came in his 'Statement of Intent - first review of the London Plan', setting out the terms of his policies due to be reviewed.
He said: 'Many existing policies are unlikely to change, however I am determined to bring forward radical changes to policy to combat climate change.
'If the world does not take rapid and sustained action to reduce greenhouse gas emissions we will leave a potential catastrophe for our children and grandchildren.'
Livingstone's announcement comes after a report by left-leaning think tank the Institute for Public Policy Research claimed that Britain would meet its commitments to reduce greenhouse gas emissions, but France, Greece and Germany would fail.
