Here we assess how emissions from short-lived non-CO₂ species like methane, hydrofluorocarbons, black-carbon, and sulphates influence CO₂ budgets.

The Structured Expert Dialogue (SED) has reviewed the adequacy of the agreed Long Term Goal of holding warming below 2°C. It has now released a technical summary - showing 2°C limit is too warm for many vulnerable systems and regions, and a 1.5°C limit would be significantly safer.

This article contains an analysis of integrated energy–economy–environment scenarios that keep warming to below 1.5 °C by 2100.

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’.
