A REVIEW OF GLOBAL CO2 EMISSIONS AND TOTAL ENERGY CONSUMPTION

Abstract

Carbon Dioxide (CO2) emissions from fuel combustion are among the leading causes of human-induced climate change and global warming today, drawing researchers’ and international organisations’ attention. CO2 emissions vary widely across the world. Countries with high emissions are setting goals and working toward reducing their environmental impact by switching to renewable energy sources. This article reviews the CO2 emissions levels emphasising the top five contributors and the changes in the sources of their total energy consumption from 2008 to 2018. It also presents the countries’ objectives to achieve carbon neutrality or to reduce their carbon emissions.
