On the occasion, UN Secretary-General Antonio Guterres has issued a message. He said, "The transport sector is responsible for approximately one quarter of all greenhouse gas emissions. 91 percent of the energy used in motorized transport on land, sea and air is derived from fossil fuels.

This makes the sector one of the most difficult to decarbonize." He said " I am convinced humanity is up to the challenge of breaking our addiction to climate-killing fossil fuels, and creating resilient, efficient and low-carbon transportation systems grounded in innovative renewable energy sources."

From electric and solar-powered vehicles, to renewable aviation fuel sources, to massive investments in green public transportation systems, to measures like carbon pricing and subsidies for low-carbon fuels we can steer our societies towards a cleaner and more sustainable path for people and planet.
