The United States, the European Union, Japan, and the BRIC countries (Brazil, Russia, India, and China) are the main emitters of GHGs. Figure 1-3 shows the distribution of GHG emissions by country or region contributing more than 2% of global emissions. Canada, with just 1.59% of global emissions, is included in the “Rest of the world” category.
