Carbon labelling is a way of mitigating climate change，reducing greenhouse gas emissions and promoting low-carbon emissions technologies. The greenhouse gas emissions （carbon footprint） emitted during the whole life cycle of production，consumption and disposal of goods are informed on the product label with a quantitative index to the consumers. This report provides a detailed overview of the development of global carbon label with its history and current situation，gives an outlook of carbon labelling in China，and summarizes the impacts of carbon labelling on China’s economy and society.
