The report discusses the future of alternative fuels and new vehicles up to 2030. Gasoline and diesel will still be the main fuels, but efforts are being made to reduce harmful emissions, especially CO2. Hybrid technology and new combustion systems are being developed to improve fuel efficiency and lower emissions. By 2030, alternative fuels could make up 10-30% of transport fuels, with biofuels like ethanol growing rapidly. Synthetic fuels show promise for reducing emissions. Energy savings will be crucial for reducing CO2 in the short term.
