- In 1997 and 1998, the California Air Resources Board (CARB) conducted an extensive evaporative emissions test program to assess the feasibility of reducing evaporative emissions standards from the current 2 gram per test total hydrocarbon (THC) standard. Seven vehicles were tested and five modified in order to determine what emissions levels would be feasible. Emissions reductions of approximately 40% resulted from these modifications. The ARB also conducted studies of non-fuel background emissions and of emissions test variability.
