[For immediate release: 20 March 2013] On Monday, the U.S. National Research Council released a comprehensive study of the technology potential for cutting oil consumption and GHG emissions by 80%...

By now everyone who wants to know does know that President Obama has promised “executive actions” on climate change if Congress continues to evade the problem. That has naturally re-energized... Heavy-duty vehicles account for 6% of total US GHG emissions—not as juicy a target as the one-third that come from power plants, but significant enough to merit a real focus this term.

Position Description The International Council on Clean Transportation (ICCT) has an immediate opening for an internship position in San Francisco, CA. The primary focus of this position will be to...

Position Description This position will work to identify, refine, and promote policies and methods to reduce the climate impact of domestic and international aviation.  The work outputs of this...

The final frontier for emissions control may be international shipping, which operated independent of controls on its engine exhaust emissions until just three years ago, when regulations on the... A new study indicates that stringent control of black carbon from ships in Arctic waters could cut warming impacts in the Arctic region by one third.

China’s State Council announced a detailed timeline for upgrading nationwide motor fuel quality to the “China V” standards, with maximum sulfur content of 10 ppm for both gasoline and diesel. The...

In 2012 ICCT carried out an analysis of “real-world” fuel consumption data in Germany for the years 2001–2010, based on data from the German website spritmonitor.de. This is an online database with... Follow-up on our analysis last year of fuel consumption data contributed by users of spritmonitor.de confirms the original findings—in fact, average discrepancy between user-reported values and the...

Last spring, my colleague Hui He blogged about then-new vehicle taxes in India. She argued that the increase in excise taxes on bigger passenger cars was a welcome step toward disincentivizing the... The Indian government's decision to phase out diesel subsidies is good as far as it goes, but it doesn't go as far as it could.

An important question when estimating the indirect land use change emissions from biodiesel feedstocks is whether vegetable oils replace each other in the market, so that increased demand for one...

Beijing’s recent episode of off-the-charts-bad air quality provoked a remarkable level of worldwide attention. The haze enveloping many Chinese cities, including not only Beijing but also other large... One culprit behind the deadly air quality in some of China's biggest cities has been receiving comparatively little scrutiny: air pollution from ships.

In October 2012, the Brazilian government approved by decree a new program to encourage vehicle technology innovation. Inovar-Auto fosters industry competitiveness by encouraging automakers to...

The basic CO2 data used in the development of the EU cost curves is derived from simulation modeling performed by Ricardo inc. This paper summarizes how the data developed by Ricardo was processed...

This paper discusses the impacts of new vehicle mass reduction data on CO2 benefit and cost curves for EU light-duty vehicles in the 2020–2025 timeframe. This paper is the third in a series, with...

先进的发动机和车辆排放控制技术需要清洁的燃油，尤其是超低硫汽油(ULSG)和超低硫柴油(ULSD)。在上个十年中，许多发达国家，包括美国、加拿大、西欧和日本，都过渡到了超低硫燃油(ULSF)，尤其是超低硫汽油和超低硫柴油。比如，2006年美国制定了30ppm的汽油硫含量标准(平均值)和15ppm的柴油硫含量标准(最高值)。这些国家还制订和实施了控制汽油的挥发度、芳烃含量和苯含量，...
