The report looks at ways to reduce greenhouse gas emissions globally to prevent irreversible climate damage. To meet the goals set in the Paris Agreement, all countries and industries need to take action. By 2080, global emissions must reach zero to limit temperature rise to 2°C (or by 2065 for 1.5°C). The transition to a low-carbon economy can happen alongside economic growth with minimal costs. Combining climate and air policies can also improve air quality worldwide, benefiting health and sustainable development goals. Uncertainties remain about future technologies like Carbon Capture and Sequestration, which could impact emission reduction pathways.
