Regional Carbon Emissions Reduction Allocation Based On Shared Responsibility Between Producers And Consumers

Climate change has begun to threaten the survival of humanity. In order to address climate change, academics and stakeholders put forward many kinds of carbon emissions allocation plan from different perspective. In order to cope with the severe situation of domestic reduction, this article will give a regional carbon emissions reduction allocation scheme based on shared responsibility between producers and consumers.Using the LMDI decomposition method and input-output method, carbon emission factors is analyzed and carbon embodied in consumption is calculated, taking Tianjin and Beijing as example. Then carbon emissions scenario analysis is carried out to explore the regional reduction potential, taking Tianjin as example.It is found that carbon embodied in consumption should is greater than the carbon emissions from production in Tianjin and Beijing. CO2 emission from production in Tianjin is 105.48 million tons, and carbon embodied in consumption is 115.5 million tons of carbon, 9.5% higher than the total production emissions. Production emission is 176.05 million tons in Beijing, and carbon embodied in consumption is 218.93 million tons, 24.4% higher than the production emissions. There is a huge carbon leakage between two regions and others.Based on the above analysis, producer-based responsibility is substituted by shared responsibility between producers and consumers as the basis for calculating each region's carbon emission responsibility and a dynamic regional carbon emissions reduction allocation model. The responsibilities are so different under different principles, which also give us the idea to peg the allocation coefficient to benefit each region gets from trade.This work will provide guidance for regional carbon emissions reduction responsibility allocation in China.
