This briefing paper analyzes 2018 electric vehicle uptake in the United States and the policy factors that are driving it. The paper catalogues forty-three unique city, state, and utility electric vehicle promotion actions and their implementation across the 50 most populous U.S. metropolitan areas in 2018.

Market projections for electric vehicle growth in India are ambitious but uncertain. In addition, the passenger car CO2 standards enforced in India are amongst the most lenient, and the super-credit multipliers available for electric vehicles are more generous compared to global practices.

This briefing paper discusses key terms related to gas in the context of energy policy and climate change mitigation goals in the European Union. It also proposes a method of categorizing gas sources based on their GHG emissions intensity and illustrates how these categories can be used to refer to gas from different sources.

In January 2019, China launched a new action plan to address air pollution by cleaning up diesel-powered on-road vehicles, off-road equipment, and ships. This plan is one part of the larger, three-year National Plan of Blue-Sky Defense, and it places stricter requirements on air pollution-prone areas.

Spain is one of the strongest hybrid electric vehicle (HEV) markets in Europe in terms of total sales volumes and relative European market shares. This paper reviews how programs, regulations, and incentives at the national, regional, and local level have shaped the HEV market in the country.

This working paper compares the market and technological characteristics of electric cars in China and the United States, based on 2015 and 2017 data. The study finds that in both Chinese and U.S. markets a handful of cities accounted for the majority of electric car sales.

This paper examines the potential of two innovative technologies—wind-assist and hull air lubrication—to help reduce emissions from new and existing ships.

For this paper, the CO2 emissions levels of two versions of the Volkswagen Golf, one diesel (Golf TDI) and one gasoline (Golf TSI), were compared both in laboratory tests and in on-road measurements under real-world driving conditions.

For this study, a C-segment passenger vehicle, equipped with a gasoline direct injection engine and compliant with the Euro 6c standard, was tested on the chassis dynamometer over the regulatory NEDC and WLTC cycles, and over two RDE-like cycles. The tests were performed at different ambient conditions and with both cold and warm engines.

Remote sensing is potentially the best option for fleet emissions monitoring, the development of an emissions factor, the identification of individual high- or low-emitting vehicles, and the screening for groups of high-emitting vehicles for market surveillance.
