CO 2 (carbon dioxide) emissions from fossil fuels, the leading cause of global warming, reached an unprecedented record in 2018 in seven years, further moving the world away from the Paris Agreement.
According to an annual scientific report published Wednesday (5) on the sidelines of the 24th United Nations Conference on Climate Change in Poland, CO 2 related to industry and coal burning, oil and gas will increase by 2.7% over 2017, after a 1.6% rise last year, after nearly three years
Only in 2011 and at the end of the financial crisis 2008, the data was worse, Glen Peters, climate scientist at the Cicero Research Center in Oslo, and one of the authors of the study, published in the Open Access magazine Earth Science Science Data, told the AFP.
"The growth of the economy and energy surpbades climate policies," said the researcher. "We are far from the trajectory that would allow us to remain in a temperature rise of 1.5 ° C to 2 ° C," goals of the Paris Accord, according to Peters.
"The sharp increase this year is mainly due to the emissions boom in China (+ 4.7%), the largest issuer in the world."
"Rhetoric is growing, but not ambition, whose efforts have nevertheless contributed to the good results of previous years, according to the 13th Annual Report of the Global Carbon Project on 80 scientists
The United States , the second polluting country, recorded an increase of 2.5% in 2018. For researchers, this does not necessarily reflect the Trump government anticlima policy, but rather an extreme winter and summer, which have increased the use
On the other hand, European emissions decreased (-0.7%), despite national disparities.
In addition to coal, which remains the enemy. one, the consumption of natural gas has increased by 2% a year in the world and 2017, and 8.4% in China, which fight against air pollution.
Regarding oil, it was estimated that a ceiling had been reached in terms of consumption. However, the number of vehicles increases by 4% each year, with a negligible percentage for electric vehicles. Fuel consumption for commercial aviation has climbed 27% in 10 years.
"While there has been remarkable progress in clean energy and electric vehicles, they are not high enough to stop the progression of fossil fuels," Peters said.
In total, fossil fuel emissions of CO 2 are expected to reach a record level of 37.1 Gt in 2018, concentrating 3/4 of greenhouse gases and 5 of Gt linked to deforestation.
With these data, it remains to be seen how the world will be able to stop emissions quickly before starting to reduce them. And if the world wants to remain at a temperature rise of 1.5 ° C compared to the pre-industrial era, it will reduce emissions by 45% by 2030 compared to 2010.
" This is not yet the case, "said Corinne Le Queré from the University of East Anglia in England.
According to climate scientist Kevin Anderson of the University of Manchester, this is a long-awaited emission cap, although it is not a return to the high levels of the 2000s. Open their eyes. "
" With a collective illusion, partial satisfaction and lies, emissions will continue to increase, "he warned.
