Worldwide fuel usage in road transportation will double by 2050 without new emissions standards, according to a new study. The report, authored by the International Energy Agency, says that affordable technology to reduce emissions already exists but that policies still need to be enacted to encourage business and consumers toward more efficient fuel-usage behaviors. The IEA recommends “fuel taxes, CO2-based vehicle taxes, fuel-economy standards and better product labeling.” Rich European and Asian nations rate highest on the IEA’s fuel-economy readiness index, while the United States receives what’s basically an “average” rating. Saudi Arabia and Venezuela, two oil-producing nations, rate worst in the index.
