CO2 emis­sions ris­ing again af­ter 3-year hia­tus

Oman Daily Observer - - FRONT PAGE -

LONDON: Driven by China’s greater use of coal, global emis­sions of car­bon diox­ide from burn­ing fos­sil fu­els are pro­jected to rise again in 2017 af­ter a three year hia­tus.

The alarm­ing pro­jec­tion for 2017 was re­vealed in a new re­port by the Global Car­bon Project and pub­lished si­mul­ta­ne­ously in the jour­nals Na­ture Cli­mate Change, Earth Sys­tem Sci­ence Data Dis­cus­sions and En­vi­ron­men­tal Re­search Let­ters.

Global emis­sions from all hu­man ac­tiv­i­ties will reach 41 bil­lion tonnes in 2017, fol­low­ing a pro­jected two per cent rise in burn­ing fos­sil fu­els, ac­cord­ing to the re­port.

The fig­ures point to China as the main cause of the re­newed growth in fos­sil emis­sions — with a pro­jected growth of 3.5 per cent.

CO2 emis­sions are ex­pected to de­cline by 0.4 per cent in the US and 0.2 per cent in the EU, smaller de­clines than dur­ing the pre­vi­ous decade, the re­port said.

In­creases in coal use in China and the US are ex­pected this year, re­vers­ing their de­creases since 2013, it added.

“It is prob­a­bly too early to say that emis­sions are on the rise again, but our es­ti­mate for 2016 and 2017 clearly does not show any sign of peak and de­cline as needed to sta­bilise the cli­mate,” said study co-au­thor Pierre Friedling­stein, Pro­fes­sor at Univer­sity of Ex­eter in Bri­tain.

It was pre­vi­ously hoped that emis­sions might soon reach their peak af­ter three sta­ble years, so the new pro­jec­tion for 2017 is an un­wel­come mes­sage for pol­icy mak­ers and del­e­gates at the UN Cli­mate Change Con­fer­ence (COP 23) in Bonn, tak­ing place this week.
