Action Tracker - Climate Action Tracker - Methodology for 1.5ºC compatible sectoral

These adjustments are made to better represent the call in the Paris Agreement for developed countries to take the lead in reducing emissions, the challenges related to stranded assets in 1.5°C compatible transitions (particularly in the developing world), and the current geopolitical context in the aftermath of the fossil gas price crisis. [...] We then take the average of the two most ambitious studies which pass the filter to represent the bottom-up perspective from the literature. [...] In the case of the EU and the US, this increase in ambition is likely due to the faster gas phase-out found in the 2023 benchmarking report (although the 2020 report did not explicitly consider fossil gas benchmarks, and so this cannot be confirmed entirely). [...] The energy use and emissions components of buildings are separated and calculated at the component level, factoring in floor area or population (depending on whether the intensity is per m² or per capita) and the emissions factors of the energy sources. [...] Therefore, we use the IAMs and the IEA targets to set the upper end of the range and extend the lower bound based on the bottom-up model; however, we do not extend it as low as the most ambitious bottom-up results.
