The UN Environment Programme's Emissions Gap Report 2024 emphasizes the urgent need for countries to enhance their climate commitments as they prepare to submit updated Nationally Determined Contributions (NDCs). To meet the Paris Agreement’s goals, global greenhouse gas emissions must be cut by 42% by 2030 and 57% by 2035. The report highlights the critical role of G20 nations, which account for 77% of emissions, in leading these efforts. Technological advancements in renewable energy present significant opportunities for emissions reductions. However, substantial support for developing countries and a redesign of international financial structures are essential for effective climate action.

G20 Nations Called to Lead Climate Action Efforts

As countries prepare to submit their updated Nationally Determined Contributions (NDCs), a new report from the UN Environment Programme (UNEP) highlights the urgent need for increased climate ambitions to meet the Paris Agreement’s goals. The Emissions Gap Report 2024 warns that unless global greenhouse gas emissions are cut by 42% by 2030 and 57% by 2035, the world could face a catastrophic temperature rise of up to 3.1°C, with severe consequences for ecosystems and economies.

The report emphasizes that even if current climate pledges are met, global temperatures could still increase by 2.6-2.8°C. This reality underscores the critical need for enhanced commitments, particularly from G20 nations, which account for 77% of global emissions. G20 members are urged to lead the charge, as their current policies remain insufficient to meet climate goals.

Technological Advancements Present Opportunities for Emission Reductions

UN Secretary-General António Guterres warned of the direct link between rising emissions and the increasing frequency of climate disasters, stating, "Record emissions mean record sea temperatures supercharging monster hurricanes." He emphasized the importance of closing the ambition, implementation, and finance gaps in climate action.

The report highlights significant opportunities to align climate mitigation efforts with immediate development needs and Sustainable Development Goals. Technological advancements in wind and solar energy are lowering costs and expanding market access, potentially facilitating faster emissions reductions. An updated assessment shows that existing technologies could provide sufficient emission reduction potential at costs below $200 per ton of carbon dioxide equivalent (tCO2e).
