FOREWORD

IRENA'sWorldEnergyTransitionsOutlookpresentsacomprehensiveandcost-effectivepathwaytolimitglobalaveragesurfacetemperatureriseto1.5°Cabovepre-industriallevelsby2050.Toachievethis,itisnecessarytodecarboniseallsectorsoftheeconomybyaroundmid-century.However,therearecurrentlysectorsthatarehardtodecarbonise-namelyheavy-dutytrucks,shipping,aviation,ironandsteel,andchemicalsandpetrochemicals.Thesesectorsalonerepresentaquarteroftheworld'senergyconsumptionandafifthoftotalCO2emissions.Thisislikelytoincreaseinthecomingdecadesiftheycontinuetorelyonfossilfuels.

Renewablescanplayacentralroleindecarbonisingthesehard-to-abatesectors,andsolutionsareincreasinglyavailabletoday;yetdespitepromisingprogressandincreasedattentionfrompolicymakers,noneofthehard-to-abatesectorsisontracktoreachnet-zeroemissionsbymid-century.

Theaccelerationofdecarbonisationinthesehard-to-abatesectorsrequiresdecisiveactionfromgovernmentsandtheprivatesector,withfar-reachingimplicationsfornationalandinternationalpolicy,technologyandinfrastructureplanning,globalcommoditymarkets,internationalsupplychains,andbusinessmodels.TheG7canplayaninfluentialroleinspearheadingdecarbonisationeffortsbyadoptingthe11recommendationspresentedinthisreport.TheGroupcanalsoworkalongsidenon-G7countriesbysharingbestpractices,removingtradebarriers,andestablishingcommonstandardsanddefinitionsforlow-carboncommodities.
