MONTREAL — Environment Minister Catherine McKenna says 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. McKenna said in a statement today implementing the Kigali Amendment could avoid up to 0.5 degrees Celsius of warming by the end of the century. McKenna and former prime minister Brian Mulroney were in Montreal today to mark the 30th anniversary of the Montreal Protocol, which was aimed at protecting the Earth’s ozone layer. Mulroney was prime minister at the time. McKenna called the Kigali Amendment a “big step forward in tackling climate change.”“Kigali will deliver new momentum to the world’s efforts to avoid dangerous global warming and accelerate clean growth,” she said in the statement.
