IPCC: world will miss 1.5°C without transforming food system


 Reacting to the publication of the Intergovernmental Panel on Climate Change (IPCC) report on the mitigation of climate change…, experts from IPES-Food called for fundamental reform of food systems to avoid catastrophic levels of global warming. The IPCC report, agreed by governments and scientists, finds that:

  • We are nowhere near on track to achieve the Paris Agreement targets of keeping global warming below 2°C, and ideally 1.5°C. 
  • Investment levels are insufficient to stay Paris aligned and investment gaps are widest for the agriculture, forest and land sector and for developing countries. Investment levels must increase by 3 to 6 times current levels to limit warming to below 2°C. 
  • Agriculture and land use* account for nearly a quarter of GHG emissions and keep rising. Transforming farming and livestock can reduce emissions and draw down carbon.
  • Demand-side mitigation efforts across all sectors – including lifestyle changes, reduction of food waste, and shift to sustainable diets [e.g., increase consumption of plant-based foods and decrease excess meat consumption] – can result in a 40-70% reduction in greenhouse gas emissions by 2050; and can improve health and wellbeing. 
  • For emissions that are extremely hard or impossible to reduce, removing carbon dioxide from the atmosphere and storing it is required. But there are limits to how possible this is and entails risks for ecosystems, livelihoods and health.

*“Land use practices such as agroforestry, intercropping, organic inputs, cover crops, and rotational grazing can provide mitigation and support adaptation to climate change via food security, livelihoods, biodiversity, and health co-benefits.” (IPCC, 2022)

“The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.”
