1-Significant efforts to reduce greenhouse gases around the world
For several years, significant efforts have been made to promote renewable energies. It has been arduous and time-consuming to implement commitments of the Kyoto Protocol and the Conferences of the Parties (COP) United Nations Framework Convention on Climate Change. Almost 20 years were needed to develop concerted action on this issue among the world’s major countries. 1
The Paris Agreement of 2015 (COP21) is historic because it engages 195 countries to reduce emissions of greenhouse gases and to stabilize climate warming due to human activities to less than 2 ° C by 2100. The main means used is the gradual elimination of fossil fuels, the main source of air pollution. It is estimated that global emissions of greenhouse gases (GHG) has reached nearly 49 billion tons of equivalent of CO2 in 2010 (latest data from IPCC ), increasing by 80% between 1970 and 2010.
The 2016 conference in Marrakech  reinforced the commitments of 2015 accelerating the adoption of the modalities by two years. The next conference will be held in Poland in 2018 and will provide an opportunity for several countries, such as Canada, Germany, Mexico and possibly the United States, to present their strategic plan.

Any global agreement cannot be held without the participation of all the major economic blocs lsuch as United States, China or Europe. The United States backing down could have a detrimental effect on other countries for reasons of competitiveness: the cost of producing fossil fuels is still lower than other types of renewable energies. The difference of costs can be regarded as unequal competition. In short, for this reason, the … Lire la suite
