Chinas 2025 National Energy Efficiency Promotion Week (June 23 to 29) and the National Low-Carbon Day (June 25) highlight the nations dedication to energy efficiency and low-emission development.At the heart of Chinas low-carbon strategy lie natural environments –-- forests, grasslands and wetlands –-- that function as large carbon banks.In 2022, the National Forestry and Grassland Administration launched 18 pilot cities and counties for forestry carbon sinks, along with 21 state-owned forest carbon-sink demonstration sites, creating pathways for high-quality carbon-sink development.A 2024 survey reveals that Chinas forests and meadows absorb over 1.2 billion tonnes of carbon dioxide comparable per year, ranking greatest in the world.Complementing natures capture power, mega-projects like the west-to-east power transmission assistance shift energy from renewables-rich areas to require centers, enhancing overall energy effectiveness while cutting emissions.This picture feature profiles Chinas presentation practices and innovative mechanisms for environmental carbon sinks, showing how policy-driven carbon-sink evaluation and trading are creating deep combination between environment defense and low-carbon development.(Cover: Wind turbines and the coastal shelterbelt forest in Weihai City, Shandong Province, east China, August 7, 2024./ VCG)
