A number of countries, including India, also signed the pledge.
But Toyota and the world’s second biggest car maker Volkswagen, as well as the United States, China and Germany, declined to sign up.
Toyota told Reuters that where the energy and charging infrastructure, economics and customer readiness exist, “we are ready to accelerate and help support with appropriate zero-emission vehicles.”
“However, in many areas of the world such as Asia, Africa, Middle East an environment suitable for promoting full zero emission transport has not yet been established,” a spokesperson said.
“We think it will take more time to make progress – thus, it is difficult for us to commit to the joint statement at this stage.”
According to a study published by the Munich Mobility Show in April, there are huge global disparities in electric vehicle ownership.
Sales are soaring in the European Union, China and the US, but cumulative electric car registrations during 2020 in South America, with a population of more than 420 million, remain below 18,000.
And registrations in Africa, home to 1.2 billion people, were exclusively in South Africa and totaled just 1,509 cars in 2020.
Volkswagen also said the tempo of electric vehicle adoption would “vary from region to region” as chief executive Herbert Diess dismissed the zero-emission pledge at the COP conference earlier this week.
“It could still make sense to use synthetic fuel cars in Latin America in 2035,” Diess said.
