Climate Action Tracker briefing: No change to warming as fossil fuel endgame

A briefing by the NewClimate Institute reporting that global warming projections have not improved since 2021, with current government 2030 targets projected to lead to 2.5°C of warming by the end of the century.

• Current government 2030 targets are projected to result in 2.5°C of warming by the end of the century, which is 0.1°C higher than the previous year's estimate. This increase is attributed to weak existing targets rather than changes in new Nationally Determined Contribution (NDC) updates.
• Warming projections under different scenarios remain high: the "Pledges and targets" scenario (binding net zero targets) estimates 2.1°C by the end of the century, the "Optimistic scenario" (including all announced targets) estimates 1.8°C, and the "Policies and action" scenario estimates 2.7°C.
• The NewClimate Institute argues that COP28 must commit to a full phase-out of fossil fuels, rejecting 'abated' fossil fuels, carbon capture and storage (CCS), co-firing ammonia with coal, e-fuels, and hydrogen boilers as ineffective or inefficient 'false solutions'.
• To keep the 1.5°C goal viable, the briefing states that emissions must peak before 2025, renewables must triple and energy efficiency must double by 2030, and fossil fuel production and use must be reduced by 40% by 2030.
• The Climate Action Tracker outlines six essential criteria for government 2035 NDCs, which are due by February 2025: substantial domestic emission cuts, alignment with net-zero pathways (overachieving 2030 targets), absolute economy-wide targets, scaled-up climate finance, a focus on domestic reductions over carbon markets/trees, and the implementation of new policies.
