The Greenpeace report that compared ten automakers evaluated decarbonisation, including phasing out engines that burn planet-warming fuels in favour of electric vehicles. Also, minimising emissions in the carbon supply chain and reusing or developing greener technology for car batteries.
Ada Kong, the senior project manager of the auto industry campaign at Greenpeace East Asia, said that Toyota is stubborn in holding onto internal combustion engines. The Japanese car giant is also "most vocal in such advocacy, domestically and abroad", he added in his statement.
Toyota declined to comment ahead of the emission report being published. But it had said in September that it would invest 13.2 billion dollars for electric and hybrid cars by 2030.
While General Motors scored the least condemning rating with C-grade, Volkswagen and Renault scored D-grade. All the other firms such as Ford, Honda and Hyundai-KIA rated F plus or minus.
Though many carmakers like Toyota are confident that hybrid technology is an effective alternative to internal combustion engines, the real-world emission reduction and fuel economy of hybrid vehicles are not as good as expected, the report further says. It also adds that none of the ten auto firms had revealed plans to phase out internal combustion engines before 2035, making the set 1.5 degrees Celcius limit for global warming- 2015 Paris Agreement- impossible.
