IPCC Report: Mitigation of Climate Change

In News: The Intergovernmental Panel on Climate Change (IPCC) has released a report, “Mitigation of Climate Change” based on the findings of Working Group III as a contribution to the IPCC’s Sixth Assessment Report (AR6).

 System transformations to limit global warming:

• Global GHG emissions are projected to peak between 2020 and at the latest before 2025 in global modelled pathways that limit warming to 1.5°C C with no or limited overshoot, and those that limit warming to 2°C.
• Without a strengthening of policies beyond those that are implemented by the end of 2020 global warming of about 3.2°C by 2100 will be reached.
• All global modelled pathways involve rapid and deep and, in most cases, immediate GHG emission reductions in all sectors.
  • Modelled mitigation strategies to achieve these reductions include transitioning from fossil fuels without carbon capture and storage (CCS) to very low- or zero-carbon energy sources, such as renewables or fossil fuels with CCS, demand side measures and improving efficiency, reducing non-CO2 emissions, and deploying carbon dioxide removal (CDR) methods to counterbalance residual GHG emissions.
• Urban areas can create opportunities to increase resource efficiency and significantly reduce GHG emissions.
• Demand-side options and low-GHG emissions technologies can reduce transport sector emissions in developed countries and limit emissions growth in developing countries.
• The deployment of carbon dioxide removal (CDR) to counterbalance hard-to-abate residual emissions is unavoidable if net zero CO2 or GHG emissions are to be achieved.
• The global economic benefit of limiting warming to 2°C is reported to exceed the cost of mitigation in most of the assessed literature.

Linkages between mitigation, adaptation, and sustainable development:

• There is a strong link between sustainable development, vulnerability and climate risks.
• Limited economic, social and institutional resources often result in high vulnerability and low adaptive capacity, especially in developing countries.
• The Sustainable Development Goals (SDGs) adopted under the UN 2030 Agenda for Sustainable Development can be used as a basis for evaluating climate action in the context of sustainable development.
