I. Introduction
Dealing with the environment and climate change is a common challenge and severe issue faced by countries around the world, and reasonable control of carbon emissions is of great significance for addressing current environmental issues such as climate change. The issue of carbon reduction has always been a concern for all sectors. China is a populous, productive, energy consuming, and emission prone country. In 2020, China's total carbon emissions exceeded 10 billion tons, accounting for about 28% of the world's total. The average annual growth rate of carbon emissions in the past five years is about 1.25%. The carbon dioxide emissions per unit of GDP in China are about 0.75kg/USD, which is about three times that of the United States and four times that of Germany. Chinese cities account for nearly 80% of carbon emissions, with terminal industries such as industry, construction, and transportation being the main sources of urban carbon emissions. Deeply studying the calculation methods, changes, and driving factors of carbon emissions from different cities and industries in China's economic development, as well as the driving factors of carbon emission growth, has important theoretical and practical significance for the country to clarify the carbon emission reduction responsibilities and obligations of each industry, and to formulate targeted emission reduction policies for each industry. This article provides a method for calculating urban carbon emissions, which provides energy consumption based carbon emission calculation and prediction methods for different industries under the goal of achieving “carbon neutrality”. It has extremely important economic and social benefits.
