Climate change is currently the biggest environmental challenge facing sustainable development in human society, and it is an inherent requirement for achieving sustainable development by actively addressing climate change. Under the increasingly strict constraints of climate governance, developed countries such as the United States, European Union countries, and Japan have responded and actively formulated low-carbon development goals and policy measures that are in line with their national conditions. These policies mainly involve various fields such as low-carbon technology, energy conservation and emission reduction, and circular development, with clear policy guidance. In this paper, the evolution of policies on marine carbon sink and carbon trading in China is summarized, providing support for better understanding the background of formulating relevant international and domestic policies.

Effective short-term prediction of regional voltage load is of great significance to the implementation of energy saving and emission reduction policies in China. Accurate prediction of real-time demand voltage can reduce power waste and carbon emissions, make outstanding contributions to delaying global climate warming, and is conducive to global environmental protection and sustainable development. On the short-term load forecasting of power system, a variant model of RNN-LSTM is tested in this paper. It effectively solves the problem of gradient explosion and disappearance caused by large amount of data input in classical RNN. On the basis of this model, optimization experiments are carried out under different super parameters to achieve better prediction results. The experimental results show that the accuracy of test set reaches 99.8%, which proves that the method proposed in this paper has certain reference value. [ABSTRACT FROM AUTHOR]
