The supply chains in the country are advancing in green management and climate action, but upstream emissions remain a challenge, according to two reports released on Thursday.
Released by the Institute of Public and Environmental Affairs (IPE), the 2026 green supply chain CITI index and corporate climate action CATI index assessed 800 companies.
Leading companies are improving environmental disclosure, encouraging suppliers to measure emissions and set targets, and promoting low-carbon technologies and renewable energy. Nearly 40 percent have begun exploring emission reductions in logistics, warehousing and packaging.
The CATI study showed that 90 percent of companies disclosed Scope 1 and Scope 2 emissions, from direct operations and purchased energy, respectively. Nearly 70 percent disclosed Scope 3 emissions across the value chain, including suppliers, transport and product use. Among 360 companies reporting Scope 1 and Scope 2 emissions for four consecutive years, total emissions peaked in 2023 and have since declined.
About half of global supply-chain leaders disclosed renewable-energy data. During the study period, they consumed more than 600 million megawatt-hours, corresponding to an estimated reduction of 335 million metric tons of greenhouse gas emissions. In addition, 3,328 suppliers disclosed Scope 1 and Scope 2 emissions through the Blue Map platform, while 995 reported renewable energy use totaling 4.15 million megawatt-hours.
The report noted that China's sulfur dioxide emissions fell from 25 million metric tons in 2006 to 2.22 million metric tons in 2024, while the share of land affected by acid rain dropped from 32.6 percent in 2006 to 2 percent in 2025.
However, decarbonization remains difficult. Among 81 companies reporting Scope 3 emissions from purchased goods and services for four consecutive years, emissions in 2025 were about 23 percent higher than in 2022. The report called for better raw-material data and wider use of product carbon-footprint information.
