McKenna says amendment signed to Montreal Protocol
MONTREAL — An amendment to the Montreal Protocol has been signed that will lower the levels of a type of greenhouse gas that warms the planet even more quickly than carbon dioxide, Environment Minister Catherine McKenna said Monday.
McKenna says implementing the Kigali Amendment could avoid up to 0.5 degrees Celsius of warming by the end of the century.
The objective of the amendment is to reduce the levels of hydrofluorocarbons, which are used in products such as refrigerators, air conditioners and aerosols.
McKenna told reporters the amendment is important because the chemicals are “very polluting greenhouse gases which were causing huge warming.”
