Abstract: The global warming potential (GWP) and global temperature potential (GTP) are two common metrics to calculate the CO2 equivalence of greenhouse gases. If the country’s emissions of greenhouse gases are calculated with GTP instead of GWP, the shares of 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 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 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.
