A transparent assessment of the current new passenger vehicle market in South Africa in terms of CO2 emissions, and provides an evaluation of the benefits of adopting fuel economy and CO2 emission standards in those vehicles.
Summarizes the potential in Europe of presently available efficiency technologies to produce fuel savings that greatly exceed the upfront costs of technology and maintenance, and evaluates emerging advanced efficiency technologies that offer even more substantial fuel savings and short payback periods over the long term.
Compares the fuel efficiency of 20 airlines operating nonstop flights between the mainland United States and East Asia and Oceania and extends the previous transatlantic fuel efficiency methodology to the transpacific market.
Analyzes results of emissions tests on 32 Euro 6 diesel passenger cars from 10 different manufacturers. Results show some automakers meeting diesel NOx emissions standards under more realistic driving conditions, while others lag badly.
Inspection and maintenance (I/M) programs are key to identifying high-emitting vehicles and mitigating their impact on air quality and climate. This paper assesses best practices for I/M programs targeting heavy-duty vehicles and makes recommendations on how to improve HDV I/M programs in the future.
Analyzes the implications of a growing natural gas vehicle fleet on the emission benefits of the U.S. HDV “Phase 2” greenhouse gas rulemaking, synthesizing data on upstream emissions, vehicle emissions, and efficiency technology.
Surveys actions being taken by state and local governments and public utilities to facilitate electric vehicle deployment in the 25 largest U.S. metro areas. Presents city-specific analysis of consumer benefits and links between policies aimed at promoting EVs and market uptake.
Discusses the use of computer simulation to certify whole-vehicle efficiency of HDVs, and compares tools used to quantify HDV CO2 emissions in the US (GEM v2.0) and EU (VECTO v2.0.3 beta; not yet used in a regulatory context).
Evaluation, based on leading technology effectiveness, technology cost, and fuel price data, of payback periods for the efficiency technologies analyzed in a companion paper on tractor-trailer technology potential.
