Challenger Trucking is a recognized EPA SmartWay® Transport Partner. That means we move California's temperature-controlled freight using technologies and practices the EPA has verified to cut fuel use, greenhouse gases, and air pollution — without compromising the cold chain.

SmartWay is a voluntary EPA program that helps the freight industry improve supply-chain sustainability. Partners commit to measuring and improving fuel efficiency and reducing transportation-related emissions.
SmartWay partners adopt technologies and practices that cut fuel use across our refrigerated fleet — from Thermo King Precedent® units to aerodynamic tractors.
Measured reductions in CO₂, NOₓ, and particulate matter on every corridor run — cleaner air for every community we serve.
We annually benchmark and report fleet environmental performance to the EPA — accountability built into our operating model.
Documented fuel and emissions performance supports customer sustainability reporting and supply-chain disclosures.
Lower carbon, same cold chain
Fuel-efficient Thermo King Precedent® reefer units and modern tractors mean fewer emissions per mile — protecting your product and the environment at once.
Supports your sustainability goals
Many shippers must report Scope 3 transportation emissions. Partnering with a SmartWay carrier gives your reporting real, EPA-recognized credibility.
Accountability you can trust
We benchmark and submit environmental performance data to the EPA — so our claims of cleaner operations are measured, not just marketed.
From San Diego to Ukiah
Every corridor we run — Southern, Central, and Northern California — moves under SmartWay practices, so cleaner-air freight is available on every lane.
