According to reports, how to accurately measure and analyze the spatial and temporal characteristics of carbon emissions in different regions, reveal its potential driving force, become the future clear carbon emission reduction targets, scientific development of emission reduction planning of the fundamental premise and the primary task.

Based on the nighttime light images, the researchers constructed a set of remote sensing assessment methods for China"s municipal energy carbon emissions and studied the temporal and spatial changes and the mechanism of energy carbon emissions in China in 19 years. The study found that China"s total carbon dioxide emissions continued to grow, the regional, provincial and municipal growth rates vary, the degree of spatial aggregation more and more obvious, the basic formation of "the eastern coastal city of high agglomeration, the western less developed cities low" The

At the same time, the per capita carbon emission intensity is basically "east" northeast> western> central ", unit GDP carbon intensity is presented as" northeast and west higher "" lower east and central. " For cities such as the western and northeastern regions that focus on energy and heavy industry, their emission reduction strategies should focus on energy structure optimization and energy efficiency. For the eastern and central and other technology, labor-intensive and light industry-oriented industries, the emission reduction strategy should focus on industrial restructuring and transformation and upgrading.
