According to an article of Nsikan Akpan in pbs, only two countries are meeting their obligations regarding the CO2 emissions. Several scientists state that global warming is in our doorstep and that the years from 2015 until today, 2019, are the warmest in human history.
The top-ten global emitters of CO2 according to a study of European Commission in 2017 are from the greatest to the lowest: China, USA, EU, India, Russia, Japan, S.Korea, Iran, Saudi Arabia and Canada. All of them are responsible for the 70% of the total world’s CO2 emissions.
The conclusion is that rapid measures are needed, from all these nations, in order to meet their commitments concerning the climate change. Renewable energy seems a very attractive solution. Hence, investments need to be focused on these alternative sources of energy.
