Evaluation of the compliance of manufacturer groups in India with fiscal year 2017–2018 fuel consumption standards and their readiness to meet more stringent requirements

Summarizes the implications of the current mass-based CO2 targets in the EU and outlines three alternatives: do away with the utility parameter altogether; use vehicle footprint instead of mass; keep the mass utility parameter, but reduce its impact on manufacturers’ CO2 targets.

An overview of CO2 emissions reduction, fuel and technology trends, and market share of new passenger cars in the European Union.


Reviews evidence on the environmental risks of growing lignocellulosic energy crops for biofuel production and policy ideas to address them.

Reviews recent research regarding greenhouse gas emissions from the manufacturing of lithium-ion batteries for electric vehicles. We analyze this research in the overall context of life-cycle emissions of electric cars as compared to conventional internal combustion vehicles in Europe. Finally, we discuss the primary drivers of battery manufacturing emissions and how these emissions could be further mitigated in the future.
