Agree­ment to cut short-lived cli­mate pol­lu­tants

Down to Earth - - THE FORTNIGHT -

A RARE note of har­mony res­onated at the Cli­mate Sum­mit in New York when part­ner coun­tries of the Cli­mate and Clean Air Coali­tion (CCAC) agreed to an ac­tion plan to deal with green­house gases that are more pow­er­ful than car­bon diox­ide (CO ) at trap­ping heat. Th­ese gases, also known as short-lived cli­mate pol­lu­tants (SLCPs), have al­ways es­caped at­ten­tion in cli­mate ne­go­ti­a­tions due to the over­whelm­ing lev­els of CO . The five mea­sures ap­proved by CCAC in­clude re­duc­ing meth­ane emis­sions by the oil and gas sec­tor, cut­ting SLCP emis­sions from mu­nic­i­pal solid waste that ac­count for 11 per cent of global meth­ane emis­sions and iden­ti­fy­ing ways to cur­tail black car­bon and par­tic­u­late mat­ter emis­sions from freight ac­tiv­i­ties across the world. The trans­port sec­tor con­trib­utes to about 22 per cent of global green­house emis­sions. Heavy-duty ve­hi­cles used in freight trans­porta­tion have a sub­stan­tial im­pact on cli­mate and air qual­ity.
