Net-Zero Transport Air Conditioning

Direct emissions from mobile air-conditioning in cars, van, buses, truck cab and trains account for almost a quarter of global GWP-weighted HFC emissions, making this a priority subsector. Natural refrigerant systems are being used in buses and some cars, but uptake is slow.
