CO2 emissions and fuel consumption standards for heavy-duty vehicles in the European Union
Heavy-duty vehicles in the European Union so far have not been subject to carbon dioxide emissions or fuel-consumption standards, making Europe the largest market without mandatory limits for such vehicles. However, the European Commission is preparing a regulatory proposal that would set mandatory CO2 limits for the heavy-duty vehicle (HDV) categories with the highest share of emissions. This paper summarizes key findings and policy recommendations from recent ICCT research related to HDV CO2 standards in the European Union, including technology baseline and cost-effective CO2 reduction potential for long-haul tractor-trailers, the highest-emitting vehicle category.
