Developed countries will start reducing HFCs as early as 2019, while developing countries will start later. Phasing down HFCs under the Protocol is expected to avoid up to 0.5°C of global warming by the end of the century, while continuing to protect the ozone layer.
All prior amendments and adjustments of the Montreal Protocol have universal support.
