The UN Environment Programme's "Closing Window: Climate Crisis Calls for Rapid Transformation of Societies" report highlights the urgent need for action to address the emissions gap and limit global warming to 1.5°C. The report emphasizes that emissions must be reduced by 45% by 2030 and reach net-zero by 2050 to avoid catastrophic consequences. The report also notes that current policies and commitments are not sufficient to meet these targets and calls for transformative changes in energy, transport, and land use systems. The report concludes that urgent and ambitious action is needed to ensure a sustainable future for all.
