Born in the wake of elevated concern about environmental pollution, EPA was established on December 2, 1970 to ensure environmental protection.
EPA's purpose is to ensure that:
- all Americans are protected from significant risks to human health and the environment where they live, learn and work;
- national efforts to reduce environmental risk are based on the best available scientific information;
- federal laws protecting human health and the environment are enforced fairly and effectively;
- environmental protection is an integral consideration in U.S. policies concerning natural resources, human health, economic growth, energy, transportation, agriculture, industry, and international trade, and these factors are similarly considered in establishing environmental policy;
- all parts of society -- communities, individuals, businesses, and state, local and tribal governments -- have access to accurate information sufficient to effectively participate in managing human health and environmental risks;
- environmental protection contributes to making our communities and ecosystems diverse, sustainable and economically productive; and
- the United States plays a leadership role in working with other nations to protect the global environment.

The mission of the California Air Resources Board (CARB) is to protect public health and mitigate the effects of climate change through regulatory and incentive programs. Regulatory measures at the vehicle tailpipe have led to substantial decreases in emissions, improvement in air quality and positive health outcomes.
Although regulations on tailpipe exhaust have resulted in significant decreases in particulate matter (PM) and other pollutants, non-exhaust sources, such as brake-wear PM, are modeled as dominant sources of vehicle PM by emission inventory models such as CARB’s EMFAC and US EPA’s MOVES models. However, both of these models primarily rely on old datasets and assumptions. As the non-exhaust emissions come to dominate total emissions, updates to emission factors and assumption are needed. They also do not take into account the likely decreases in brake-wear PM that will occur from fleet turnover and increased market share of vehicles equipped with regenerative braking.
To reduce uncertainties in current treatment of brake-wear PM emissions, CARB, in collaboration with Caltrans and U.S. EPA, is exploring various methods to quantify brake-wear PM emission rates. This includes controlled laboratory methods as well as roadside studies. Using recently developed testing methods, CARB is testing modern brake materials, under realistic braking behavior, testing various vehicle types and weights, and sampling with state-of-the-art PM measurement technologies. Laboratory methods will be used to develop new emission factors and source profiles, which can be used to estimate impacts of brake-wear in near-roadway environments. With this effort, CARB will improve EMFAC’s treatment of brake-wear PM and to characterize the exposure potential of populations living near major roadways to better understand the impact of this source on California’s air quality.
