Comparison of Annual GHG Reduction Rates from 2020-2030 Based on Submitted or Reported Climate Commitments (2020 Pledges and INDCs) for Canada, EU, Japan and US

The document outlines the data sources and assumptions used to calculate annual GHG reduction rates for Canada, the EU-28, Japan, and the US between 2020 and 2030. It specifies that estimates are provided both with and without the land use, land-use change, and forestry (LULUCF) sector to ensure comparability. The calculations rely on historical emissions data from national inventory reports submitted to the UNFCCC and specific target percentages for 2020 and 2030 (or 2025/2050 for the US) relative to various base years.

• The analysis provides two sets of decarbonization rate estimates for the 2020-2030 period: one that excludes and one that includes the land use, land-use change, and forestry (LULUCF) sector, because the treatment of this sector varies across the four analyzed entities.
• The 2020 GHG reduction targets used for the estimates are a 17% reduction from 2005 levels for Canada and the United States, a 20% reduction from 1990 levels for the EU-28, and a 3.8% reduction from 2005 levels for Japan.
• The 2030 GHG reduction targets used for the estimates are a 30% reduction from 2005 levels for Canada, a 40% reduction from 1990 levels for the EU-28, and a 26% reduction from 2013 levels for Japan.
• For the United States, the 2030 emissions levels are interpolated based on a 2025 target of a 27% reduction from 2005 levels and a 2050 target of an 80% reduction from 2005 levels.
