The CHTS provides regional and inter-regional trip data that statewide and regional
travel models require in order to develop and calibrate forecasts for 2015, 2020, 2035
and 2040 Greenhouse Gas emissions (GHG). SB 375 (Sustainable Communities/
Climate Protection Act of 2008) and SB 391 (CA Homes and Jobs Act of 2013) require
GHG forecasts.
