More and quicker action is still necessary, but the global energy system seems to be changing course. This is confirmed by the new edition of the "Statistical Review of World Energy" by British Petroleum. The report slightly modifies the data published a few months ago by the International Energy Agency (IEA) but essentially confirms the main point: in 2015, CO2 emissions remained the same as in 2014. This is a new trend compared to the steady increase in emissions that took place over the past decade. According to the report, 2 main factors have contributed to this: on the one hand, the decrease in consumption due to the slowdown on the world economy; on the other hand, the important developments in energy efficiency and in renewable energy sources. Within this context, China has played a significant role having recorded a decrease in emissions for the first time in 20 years.
