In the context of dual carbon, IPE leveraged its long-standing experience of environmental data analysis, as well as IT and mapping technologies, and refocused its efforts in 2021 to building carbon data infrastructure and developing digital carbon management and carbon reduction solutions. In particular, IPE upgraded the low carbon map to the Blue Map for Carbon, which showcases climate and energy data at the global, provincial, municipal and corporate levels. IPE also cooperated with China Academy of Environmental Sciences to develop China's provincial and city-level carbon neutrality index and conducted the first annual evaluations.
