Greenhouse gas (GHG) emissions

Key findings• Overall, greenhouse gas (GHG) emissions are still growing worldwide, with CO 2 predominant and the main driver of the overall trend.Since 1990, energy-related carbon dioxide (CO 2 ) emissions have grown more slowly in OECD countries than they have worldwide.Today OECD countries account for less than half of world GHG emissions, but still emit far more CO 2 per capita; 10 tonnes per person compared with with 4 tonnes per person in most other regions.Many OECD countries have decoupled their carbon dioxide (CO 2 ) emissions from GDP growth, though decoupling remains weak, and in many countries emissions have continued to rise.• Sulphur oxide (SO x ) and nitrogen oxide (NO x ) emissions have decreased significantly since 1990 for the OECD as a whole (-69% and -36% respectively).Almost all OECD
