About us

Climate Action in Transportation (CAT) is a platform of software tools that help decision-makers measure, visualize, and act to reduce emissions from on-road transportation, for US states, counties, and metropolitan planning organizations. This web-based platform (1) estimates any county’s emissions, (2) visualizes emissions with dashboards and downloadable content, and (3) identifies optimal low-carbon transportation policies for that county.

This platform is powered by ‘CATSERVER’, our growing database of emissions estimates for numerous pollutants for most every county in the United States. CATSERVER and CAT products use estimates generated by the EPA’s MOVES software - the gold standard for emissions estimation in the US - or validated models derived from MOVES.

Housed at Cornell University, our team includes researchers, postdocs, PhD students, and Masters students from many disciplines, led by Lead Developer Dr. Tim Fraser and Principal Investigator Dr. H. Oliver Gao.

What we are doing

Throughout the US, state, county, and city decision-makers are using the EPA’s MOVES software to estimate emissions from transportation as they design and upgrade their transportation systems. But running MOVES requires significant computing resources, time, and technical expertise, posing prohibitive barriers to effective climate action. Then, drawing conclusions from raw MOVES databases requires significant data analytics and visualization expertise. The CAT platform and its suite of software products help decision-makers access MOVES’s insights without these barriers, applying data analytics and visualization tools to (1) pre-run MOVES estimates, (2) real-time MOVES estimates with distributed cloud computing, and (3) ML and AI models of MOVES data.

Our objective is to bridge these twin (a) data access and (b) data communication problems to accelerate climate action in transportation, by offering policymakers a faster, more accessible, and credible platform for assessing the impacts of transportation decisions on greenhouse gas emissions.
