Response Between CO₂ Emissions And Economic Development

Since the establishment of the Intergovernmental Panel on Climate Change（IPCC）,CO₂ emission has been hotly debated.How to deal with the continued growth of global CO₂ is a serious challenge for all parties.Based on the data of population,economy,and CO₂ emissions of 177 countries from 1995 to 2015,this paper has gone through three steps of analysis.First,this paper compares the CO₂ emissions of countries（regions）with different income levels from the temporal and spatial scale.Then,this paper uses statistics and econometrics methods to explore the cooperative response between CO₂ emissions and economics,and further determine the stage of CO₂ emissions in different income countries.Finally,from the perspective of equality,this paper measures CO₂ inequality and income inequality,and the response relationship between them are determined.Understanding the CO₂ emissions of different income level countries is important for the formulation of emission reduction policies.It also laid the foundation for the promotion of a global low-carbon economy.The specific conclusions of this study are as follows:（1）There are obvious differences in CO₂ emissions of different income level countries（regions）.High-income region（HI）have successfully controlled the CO₂emission,but the total emission and per capita emission still very high,so it’s still have to bear the major CO₂ emission reduction pressures.The upper medium income（LMI）and lower medium income regions（UMI）have become a major source of CO₂emissions,which is the backbone of future CO₂ reduction efforts.Compared with other income level regions,CO₂ emissions from low-income region（LI）contribute little to the world,but their future CO₂ emission growth potential cannot be ignored.From the perspective of industrial CO₂ emissions,the proportion of CO₂ emissions in different industrial sectors varies greatly,and there are similarities and differences between different income levels.（2）There are obvious geographical distributions and spatial classification differences in CO₂ emissions and their increments.East Asia and North America are the world’s major CO₂ sources.Africa contributes very little to global CO₂ emissions.Asia and Latin America are important growth poles for CO₂,total CO₂ emissions and per capita CO₂ emissions show positive growth.The CO₂ emission reduction work in Europe has remarkable results,the total CO₂,per capita CO₂ and Unit GDP CO₂（CO₂intensity）showed significant negative growth.From the spatial classification,we can find that different income countries are in different classification states,and the classification types are closely related to the income level.（3）The Carbon Kuznets Curve（CKC）hypothesis was confirmed,and different income level countries have different CO₂ emission stages.With the increase of income level,the country’s CO₂ emission stage is more idealized.From the perspective of equality,CO₂ emissions and income are developing in a more equitable direction,and inter-regional inequality contributes significantly to overall inequality.There is a positive relationship between CO₂ inequality and income inequality,and as the income level increases,the positive relationship becomes stronger.
