1 point; applies to all eight BD+C adaptations. Use no refrigerants or only those with zero ozone depletion potential and a global warming potential below 50; or comply with ASHRAE 15-2019, implement a refrigerant management plan (leak detection, retrofit, end-of-life) for systems over 0.5 lb, and keep the weighted lifecycle impact of all HVAC&R equipment within 100 (IP; 13 SI) using the LCGWP plus LCODP formula; retail stores with commercial refrigeration also meet charge, emissions and leak-test limits or hold GreenChill silver.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
