Confusion remains about concepts like carbon neutrality, climate neutrality, full decarbonisation, and net zero carbon or net zero greenhouse gas emissions. Here we clarify these concepts.

This briefing note outlines suggested time frames for reaching zero global CO2 and total greenhouse gas emissions for ‘below 2°C’ and ‘below 1.5°C by 2100’.

Small island states and the least developed countries have called for warming to be brought back to below 1.5° by 2100. The 1.5°C warming limit is now under review for consideration next year by the UNFCCC.

This report analysis how the 2°C goal has affected global climate ambition and makes the case for increasing this goal to 1.5°C due to the projected increased severity of climate impacts and the required ambition to counter the speed of climate change.
