Oil major BP said carbon dioxide from emissions from energy consumption rose by 0.1% last year in its smallest advance since 2009.
The company said it was caused by lower coal use and sluggish growth, in its annual energy review.
Last year’s rise, which slowed from 0/5% in 2014, took global CO2 emissions from energy use to around 33.508billion tonnes.
Chief executive Bob Dudley, said:”Last year saw a flattening of carbon emissions from energy consumption. That’s come about from slowing demand growth and a shift away from coal to natural gas and renewables in the energy mix.
“But it is only a very small step in the right direction given the scale of the challenge (to reduce emissions).”
In 2015, gloabl primary energy consumption rose by 1% , below a 1.1% rise in 2014 and the 10-year annual average of 1.9%, the review showed.
Coal consumption fell by 1.8% versus a 10-year annual average of 2.1% growth.
Coal’s share of global primary energy consumption fell to 29.2 percent, taking its lowest share since 2005.
Emissions growth was below average in every region except Europe and Eurasia, BP said.
Eurostat, the Statistical Office of the European Union, estimated last month that the EU’s CO2 emissions from energy use in 2015 increased by 0.7 percent.
