To serve the purpose data regarding two of the main sectors of the economy namely: production and logistics along with other control variables is used from IPCC. The study is conducted for top 65 countries of the world from 1970 to 2016. The countries are categorized from most to least in the list of CO2 emissions on the basis of data extracted from World Bank Indicators. This study has estimated two models each of production and logistics taking instance of two energy resources with other independent variables like population density, trade openness and industry value added. The findings of the first model of logistics show that CO2 emissions fall by 2.2% with renewable energy resources. The results of the second model reveal that CO2 emissions tend to increase with fossil fuel energy consumption. Similarly, in case of production, the first model indicates the inverted U shaped graph reflecting the initial increase in CO2 emissions with renewable energy consumption and fall in it eventually in the long run. The impact of other independent variables is subject to the careful implementation as in case of logistics, with renewable energy consumption practices the industry value added shows a substantial 91% decrease in CO2 emissions, although population density a marginal increase of 1% and trade openness shows a decrease in CO2 emissions by almost 90%, while with continuation of fossil fuel energy consumption practices although the CO2 emissions decrease but the impact is very little. Taking instance of production sector the impact with both renewable and fossil fuel energy consumption is little but it would be wise enough for the governments of the countries to adopt renewable energy consumption practices for a longer more prosperous environmental preservation.en-USThesis
