Mobile air conditioning (MAC) systems are a significant source of greenhouse gas (GHG) emissions from vehicles. This study, conducted by the ICCT in partnership with the Institute for Governance & Sustainable Development (IGSD), examines the GHG benefits and costs of switching to improved refrigerants and more efficient AC systems.
Current emissions of anthropogenic greenhouse gases (GHGs)
have already committed the planet to an increase in average
surface temperature by the end of the century that may be above
the critical threshold for tipping elements of the climate system
into abrupt change with potentially irreversible and unmanageable
consequences. This would mean that the climate system is
