Shares Differences of Greenhouse Gas Emissions Calculated with GTP and GWP for Major Countries

The global warming potential （GWP） and global temperature potential （GTP） are two common metrics to calculate the CO2 equivalent of greenhouse gases （GHGs）. If the country＇s GHG emissions are calculated with GTP instead of GWP, the shares of the EU, USA, Japan, Canada and South Africa rise in the pe...

Description
Summary:The global warming potential （GWP） and global temperature potential （GTP） are two common metrics to calculate the CO2 equivalent of greenhouse gases （GHGs）. If the country＇s GHG emissions are calculated with GTP instead of GWP, the shares of the EU, USA, Japan, Canada and South Africa rise in the period 1990-2005, and those of Brazil, Australia, China, India, Mexico and Russia decrease. From 2015 to 2030, the projected shares of the EU, USA, Japan and China will increase, but those of Russia, Canada, Australia, India, Mexico and Brazil will decrease. The reduced shares of Brazil and Australia and increased share of the EU might be one of the important reasons that Brazil and Australia suggested to adopt GTP instead of GWP as early as possible, but the EU opposed it.
