Ten key short-term sectoral benchmarks to limit warming to 1.5℃

摘要

This article identifies and quantifies the 10 most important benchmarks for climate action to be taken by 2020-2025 to keep the window open for a 1.5 degrees C-consistent GHG emission pathway. We conducted a comprehensive review of existing emissions scenarios, scanned all sectors and the respective necessary transitions, and distilled the most important short-term benchmarks for action in line with the long-term perspective of the required global low-carbon transition. Owing to the limited carbon budget, combined with the inertia of existing systems, global energy economic models find only limited pathways to stay on track for a 1.5 degrees C world consistent with the long-term temperature goal of the Paris Agreement.
