The UK has been a world leader in setting carbon targets and curbing CO2 emissions, and it has been at the cutting edge of climate diplomacy. It has benefited, attracting low carbon investment and global prestige. Its policies have been copied across the world. In contrast, the US has had high CO2 emissions and low interest in climate diplomacy.
However, over the past four years the balance has shifted. The Obama administration has introduced policy to restrain emissions at home, and climate is now a diplomatic priority.
This infographic compares UK and US attitudes and commitments to climate leadership and how this has changed over time.
