The United Nations Environment Programme has launched a new report titled "Emissions Gap Report 2026: The Point of Return," warning of the need for urgent action to reduce greenhouse gas emissions. The report indicates that the world needs to reduce emissions by 18% by 2030, and 45% by 2035, to ensure global temperature rise is limited to between 1.7 and 1.8 degrees Celsius, paving the way for a return to the 1.5-degree Celsius goal by the end of the century.
Temperature Projections and Available Pathways
According to the data provided, the continuation of current policies could lead to a temperature rise of 2.8 degrees Celsius during this century. If nationally determined contributions are fully implemented, this rise could decrease to 2.6 degrees Celsius. However, the most optimistic scenario, which relies on achieving climate neutrality goals, remains capped at 2.1 degrees Celsius, confirming the urgent need to enhance international efforts to avoid dangerous climate repercussions such as floods, heatwaves, and forest fires.
The Role of Renewable Energy and Energy Transition
The report highlights successes achieved in the renewable energy sector, where electricity generation capacity from renewable sources grew at a rate three times higher than expected, and solar photovoltaics increased sevenfold. To achieve the required climate path, energy efficiency must be doubled and clean energy expanded globally, with a necessity to sharply reduce reliance on fossil fuels, including lowering the share of coal, oil, and gas in the total global energy mix.
Decarbonization Challenges and International Commitments
The optimal scenario requires the removal and storage of approximately 320 gigatons of carbon dioxide from the atmosphere during this century. Energy transition plans also require reducing methane emissions by 25% by 2035. The report emphasizes that countries have the opportunity and capacity to accelerate climate action through strong economic policies such as carbon taxes and emissions trading systems, which have proven effective in reducing emissions in multiple sectors around the world.
