Summary

TT: Greenhouse Gas Logic (GHC) has been implemented on Toyota A/C Systems to reduce tailpipe emissions. The federal government issues café (Corporate Average Fuel Economy) credits to vehicle manufacturers that implement new technologies that reduce the carbon footprint of the vehicles they produce. GHC Logic technology works by automatically operating the HVAC system in REC mode when certain operating conditions are met, improving the A/C systems cooling efficiency and reducing the vehicle's C02 emissions.
