Better public transport systems are key for greener cities

A 2022 report by The Eco Experts shows that the transport industry accounts for 20% of global carbon dioxide (CO2) emissions. This is roughly 8.43 billion metric tonnes (9.29 U.S. tons) of greenhouse gas (GHG) emissions each year. These emissions come from burning fossil fuels to power cars and other vehicles, trains, airplanes and ships. All these emissions make it the world’s second most polluting industry after fossil fuels.
