At the COP28 climate summit, 118 countries, including Australia, pledged to triple the world’s renewable energy capacity by 2030. This ambitious goal, led by the European Union, the United States, and the UAE, aims to phase out CO2-emitting fossil fuels from the global energy system by 2050. The pledge is part of a comprehensive strategy to decarbonize the energy sector, which contributes to about three-quarters of global greenhouse gas emissions. Despite challenges, this initiative represents a significant commitment to transitioning towards clean energy sources like solar and wind power. The plan includes phasing down unabated coal power and doubling the global rate of energy efficiency by 2030. Countries like Australia have already made significant strides in renewable energy, with plans to achieve 82% renewables by 2030.
