This briefing paper analyses the available information in the 2014 UNEP Emissions Gap Report 2014 (‘EGR’) and the IPCC AR5 to produce recommended benchmark emission levels for 2020, 2025 and 2030.

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.
