IPCC Unsummarized

The briefing contends that the IPCC's mitigation pathways are skewed by economic assumptions in integrated assessment models (IAMs) and political pressures during the Summary for Policymakers (SPM) negotiation process. It argues that avoiding a 1.5°C overshoot is imperative to prevent irreversible harm and that the most feasible, cost-effective path is a rapid phaseout of fossil fuels combined with scaling renewables and reducing energy demand. The document warns that reliance on CCS, BECCS, and DACCS is a dangerous gamble, as these technologies are unproven at scale, costly, and may prolong fossil fuel use while threatening food security and biodiversity.

• The IPCC's Working Group III report contains a disconnect where the Summary for Policymakers (SPM) downplays warnings about the risks of temperature overshoot and over-relies on unproven technologies, despite the full report's scientific consensus on the need for a rapid fossil fuel phaseout.
• The use of high discount rates in IAMs biases mitigation scenarios toward delayed action and a greater reliance on future carbon dioxide removal rather than immediate fossil fuel phaseout.
• The negotiation process for the Summary for Policymakers was highly politicized, with fossil-fuel producing countries pushing for the inclusion of 'unabated' fossil fuels to prioritize carbon capture and storage (CCS) and delay the phaseout of fossil fuel infrastructure.
• Scaling up wind and solar energy is identified as the fastest and cheapest route to reducing emissions, with nearly 8 Gt of annual CO2 emissions avoidable at a cost of $50 per ton or less.
• Carbon capture and storage (CCS) is characterized as a high-cost technology that is unproven at scale and may actually increase the use of fossil fuels by allowing them to be used longer.
• Direct Air Capture with Carbon Capture and Storage (DACCS) is highly resource-intensive; removing 10 gigatons of CO2 per year could require up to 100 exajoules of energy, equivalent to current total global electricity production.
• Bioenergy with Carbon Capture and Storage (BECCS) poses significant risks to biodiversity, food security, and the rights of Indigenous Peoples, and may result in a 'negative carbon sink' due to land-use changes.
• Avoiding a 1.5°C overshoot is critical because exceeding this threshold leads to irreversible impacts on ecosystems and human rights, and increases the risk of triggering climate tipping points.
• Effective mitigation must be grounded in climate justice and a just transition, as the current climate crisis is rooted in unsustainable production and consumption patterns and political economic institutions that lock in resource-intensive development.
