Climate change is real and already occurring, according to scientific evidence. Significant reductions in greenhouse gas (GHG) emissions of 60-80% below 1990 levels are needed by 2050 to mitigate climate change. For the transportation sector, a fair target would be a 60-80% reduction below current levels. Transportation GHG reductions can come from five areas: vehicle efficiency, low-carbon fuels, reducing vehicle miles traveled (VMT), improving vehicle and system operations, and making construction and maintenance more sustainable. Vehicle and fuel technology improvements can achieve most reductions for light-duty vehicles (LDVs) through 2030, but additional strategies are needed like lowering VMT growth, improving traffic flow, expanding carpooling and transit, and
