United States of America The USA intends to reduce net GHG emissions by 26–28 per cent from 2005 by 2025, including LULUCF. The target covers all IPCC sectors and seven greenhouse gases.
The modelling groups largely agree on the impact of the USA’s INDC on its emissions.
Figure A1.13: GHG emissions of the United States of America under the 2020 pledge, INDC and current policy trajectory case The official studies are: UNFCCC inventories for historic data, 6th National Communication for current policy projections (UNFCCC National Reports, 2015). For INDC: INDC submission (UNFCCC, 2015). The analysis in this report uses the ‘with measures’ scenario from the 6th National Communication. The US indicates that its current trajectory is better represented by the ‘with additional measures’ scenario. The national studies are: Belenky (2015) and Hausker et al. (2015). Current policies only from Belenky (2015). 2030 INDC estimate only from Hausker et al. (2015)
