CO2 emissions need to reach net zero by 2050 to limit global warming to 1.5°C
Climate change, driven by natural and human factors like fossil fuel use, agriculture, and deforestation, is altering global weather patterns and causing disruptions to water resources, ecosystems, and crop yields. Increasing concentrations of greenhouse gases, such as carbon dioxide and methane, trap solar radiation, leading to global warming, especially in oceans. Scientific evidence indicates a higher risk of significant environmental changes if global temperatures rise beyond 2°C above pre-industrial levels. Since 1992, most countries have been part of the United Nations Framework Convention on Climate Change, a treaty providing a framework for international cooperation for combating climate change. This was followed by the adoption of the Kyoto Protocol in 1997 which commits its developed country Parties to internationally binding emission reduction targets, and the Paris Agreement in 2015 which sets out an international action plan to limit global temperature rise to well below 2°C above pre-industrial levels. Achieving these targets requires systemic changes in global emission patterns. The energy sector can contribute through demand-side interventions, energy efficiency, flexible systems, and renewable energy sources to help mitigate climate impacts and limit temperature rise.
