Compliance and enforcement

As vehicle emissions and efficiency regulations have become more stringent, the technologies used to mitigate emissions and reduce fuel consumption have become increasingly complex. A modern car or truck has a powerful computer under its hood and a small chemical plant, in effect, as part of its exhaust system, meaning there are many potential areas for system failure—or manipulation. All governments face significant challenges in ensuring that emissions and efficiency standards meant to protect public health and welfare are met in practice and not just in theory. Technology will continue to advance, and temptations to evade or subvert regulations will remain. An essential component of clean transportation policy, therefore, is effective measures to ensure that the intended outcomes from emissions-control and fuel-efficiency programs materialize, in fact, throughout the vehicle lifecycle.

ICCT research and analyses have played crucial roles in illuminating the scale and scope of disparities between vehicle-efficiency targets or pollutant emissions standards and “real-world” achievement in everyday use. ICCT also provides data and expertise to efforts by government agencies and other stakeholders engaged in designing and operating programs to measure and track vehicle performance, spot problems such as systematically high-emitting vehicle models, and identify workable and effective resolutions that ensure that efficiency and pollution standards are met in practice as well as in theory.

The overall goal of the TRUE Initiative is to measure and publish real world emissions data and to work with selected cities to utilize this data to help inform city-level measures to control urban transportation emissions. The first cities we have been focusing our efforts on are London and Paris.

Real-world NOx emissions from remote sensing: An update of the TRUE rating

We recently finished collecting, cleaning up, and crunching the numbers from a real-world emissions measurement campaign in London using remote sensing. And we've updated the TRUE rating that categorizes vehicles based on NOx emissions to incorporate the additional data. Here are the highlights.
