Group 1 - The conference on "International Zero Carbon Cities and Villages and Zero Carbon Building" was held in Beijing, focusing on urban renewal, energy-saving mechanisms, policy support, and financial empowerment in the context of carbon neutrality [1] - Roxana Slavcheva from WRI highlighted that building energy efficiency is one of the most cost-effective strategies for emission reduction, with a potential 83% reduction in global building sector carbon emissions by 2050 if best practices are widely adopted [1] - Despite progress in Europe, globally less than 1% of existing buildings can achieve zero carbon emissions, facing challenges such as high initial costs and low perceived investment returns [1] Group 2 - The building industry is urged to invest in energy efficiency and renewable energy to meet the International Energy Agency's net-zero carbon goals, while also promoting low-carbon concrete and other alternative products [2] - WRI's research indicates that by adopting existing low-carbon technologies, Chinese cities could reduce nearly 48% of carbon emissions by 2030, with almost half of this potential coming from the building sector [2] - The transition to low-carbon buildings requires collaboration between public and private sectors to innovate financial tools, reduce investment risks, and support the widespread implementation of low-carbon technologies [2] Group 3 - WRI emphasizes that building energy efficiency is a key focus area, and integrating green low-carbon strategies into urbanization is crucial for achieving China's dual carbon goals and enhancing urban climate resilience [3]
