Air Quality and Climate Change

Air quality management in the 21st century is changing. The previous focus on localized air pollution problems, such as ozone nonattainment, is evolving into a much broader and integrated treatment of issues ranging from local “hot spot” analysis of toxic air pollutants, to attainment of air quality standards at a regional level, and to addressing mitigation of climate change occurring at a global scale.

TranSystems provides over 30 years of experience in conducting air quality and climate change analysis. We offer a full range of consulting services and support, and we are recognized for our in-depth knowledge of air pollution and greenhouse gas (GHG) technical and policy issues. Our experts also have specialized experience in criteria air pollutant (CAP), toxic air pollutant (TAP) and GHG emission inventory development and improvement, complex economic and policy models, mitigation support, cost evaluations, and information technology (software/database) development.

TranSystems experts provide support across all air pollution and GHG sources and sinks, including those from all forms of transportation, electric power, stationary fuel combustion, manufacturing, waste management, agriculture, and forestry. Our clients rely on us to provide clear assessments of where emissions come from; what their impacts are to health and the environment; how they can be controlled; and what the costs and benefits are for differing control approaches.

We serve a wide array of clients in both the public and private sectors. These include the US Environmental Protection Agency, state and provincial governments, metropolitan planning agencies, municipal governments, industry trade associations, the Port Authority of New York/New Jersey, power sector clients like the Sacramento Municipal Utility District, and the Center for Climate Strategies.
