Construction And Application Of Carbon Palma Ratio

The grim situation of global warming requires all countries to accelerate the emissions reduction process under the equity principle,therefore it is of great significance to study the equality of carbon emissions.This paper attempts to measure carbon emissions equity through the construction and application of Carbon Palma Ratio at individual level.The main research contents include:(1)Propose the definition and methodology of Carbon Palma Ratio.(2)Calculate the Carbon Palma Ratios of various countries including China and analyze their gaps in emissions equity.(3)Calculate global Carbon Palma Ratio and analyze the degree of inequality among individuals.(4)Consider the sensitivity of Carbon Palma Ratio to specific parameters.Results indicate that:(1)China's Carbon Palma Ratio in 2014 is 2.02,showing obvious inequality.Therefore,precise policies should be formulated to guide the emissions reduction activities by different groups.(2)Although Annex I countries' degree of equity is better than that of Non-Annex I countries,based on their higher total emissions,it is necessary for them to recognize historical responsibility and implement systemic emissions reductions.The current Carbon Palma Ratios of developing countries are relatively high,thus positive actions should be taken to promote the improved distribution of domestic income and carbon emissions.(3)Global Carbon Palma Ratio is as high as 7.98 in 2014,which exceeds the ratio of any country.Therefore,when territorial restrictions are broken down and equity is redefined,global carbon emissions situation is even worse.(4)The sensitivity analysis finds that Carbon Palma Ratio is not sensitive to income fitting function,while it is sensitive to emissions-income elasticity.Although Greenhouse Gases Palma Ratio is lower than Carbon Palma Ratio,it is still above 4.
