Low-carbon big data In the field of low-carbon sustainable development, different stakeholders have common but different demands. For the government (including local government), sufficient and valid data (such as carbon emission of local corporation) is the basis of policy-making process, especially in the case of making scientific goal of carbon emission and related strategy. For corporations, they need to know their own emissions and the level of their industry in order to reduce the emission at the lowest cost and set a scientific goal.
