Below 2°C or 1.5°C depends on rapid action from all countries

Climate Action Tracker - Policy Brief

Published: 04/06/2014

The UNFCCC Bonn session in June 2014 is aimed at increasing emission reduction actions in the pre-2020 period, as well as substantially improving mitigation ambition for the post 2020 period in the new climate agreement to be concluded next year. In this update, the Climate Action Tracker re-evaluates the required level of global and regional levels of ambition for 2020, 2025 and 2030 to limit warming to below 2°C or 1.5°C, based on a new analysis of the IPCC AR5 emissions database.

Limiting warming below 2°C with a high chance of success means that total GHG emissions would need to be zero between 2060 and 2080, and likely negative thereafter. CO2 emissions from fossil fuel combustion and industry would need to be zero between as early as 2045 and not later than 2065, and be negative thereafter.

The update also looks at past and current global decarbonisation trends and related to that at recent policy developments in the USA, which have announced to reduce emissions from the electricity sector.
