Emis­sions rules for air­craft pro­posed

The Pak Banker - - BUSINESS -

A UN panel on Mon­day pro­posed long-sought green­house gas emis­sions stan­dards for air­lin­ers and cargo planes, draw­ing praise from the White House and crit­i­cism from en­vi­ron­men­tal­ists who said they would be too weak to ac­tu­ally slow global warm­ing.

The In­ter­na­tional Civil Avi­a­tion Or­gan­i­sa­tion said the agree­ment reached by the agency's en­vi­ron­men­tal panel re­quires that new air­craft de­signs meet the stan­dards be­gin­ning in 2020, and that de­signs al­ready in pro­duc­tion com­ply by 2023. There is also a cut­off date of 2028 for the man­u­fac­ture of planes that don't com­ply with the stan­dards. The stan­dard must still be adopted by the agency's 36-na­tion gov­ern­ing coun­cil, but sub­stan­tive changes aren't ex­pected.

The stan­dards would be the first ever to im­pose bind­ing en­ergy ef­fi­ciency and car­bon diox­ide re­duc­tion tar­gets for the avi­a­tion sec­tor. When fully im­ple­mented, the stan­dards are ex­pected to re­duce car­bon emis­sions by more than 650 mil­lion tonnes be­tween 2020 and 2040, equiv­a­lent to re­mov­ing over 140 mil­lion cars from the road for a year, ac­cord­ing to the White House.

The stan­dards would re­quire an av­er­age four per cent re­duc­tion in fuel con­sump­tion dur­ing the cruise phase of flight start­ing in 2028 when com­pared with planes de­liv­ered in 2015. How­ever, planes burn the most fuel dur­ing take­offs and land­ings, while cruis­ing at high al­ti­tudes is al­ready the most fuel-ef­fi­cient pe­riod.

The agree­ment is the first of two im­por­tant op­por­tu­ni­ties this year to re­duce car­bon emis­sions from avi­a­tion. The se­cond op­por­tu­nity will come later this year when ICAO tries to reach an agree­ment on a "mar­ket-based ap­proach" that would use eco­nomic in­cen­tives to fur­ther re­duce avi­a­tion car­bon emis­sions. "To­day's agree­ment is an im­por­tant sig­nal that the in­ter­na­tional com­mu­nity is well-po­si­tioned to rise to the chal­lenge of im­ple­ment­ing a global mar­ket- based ap­proach to re­duce avi­a­tion emis­sions," the White House said in a state­ment.
