Former Prime Minister Brian Mulroney addresses delegates on the occasion of the 30th anniversary of the Montreal Protocol, Monday, November 20, 2017 in Montreal .
In the spring of 1985, the news went around the world. British scientists reveal in the journal Nature the presence of a hole in the ozone layer, just above the South Pole. The article has a resounding effect. Overnight, citizens become aware of the threat of such a phenomenon in their daily lives.
The depletion of the ozone layer leads to an increase in ultraviolet rays which are harmful to living beings on Earth, because these rays notably cause skin cancers. For every 1% decrease in the ozone layer, the incidence of this type of disease increases by 4%.
Shortly after publication of this information by scientists, the international community is mobilizing. This involves eliminating the gases which are responsible for the deterioration of the ozone layer, the famous chlorofluorocarbons (CFCs).
In 1987, barely two years after the discovery of the hole, Brian Mulroney proposed to the United Nations that Montreal host an international conference. The goal: strike a deal to eliminate these gases. This is how the Montreal Protocol was born, on September 16, 1987.
It’s a success across the board. Not only does the agreement allow the ozone layer to gradually recover, but it also helps protect the planet's climate. CFCs are also powerful greenhouse gases (GHGs), and their elimination makes it possible to better combat climate change. It is perhaps the most successful international agreement to date, said former UN Secretary-General Kofi Annan.
The Montreal Protocol is a model of its kind, since it was designed to be modified as scientific knowledge evolves. Thus, in 2016, the so-called Kigali amendment made it possible to add hydrofluorocarbons (HFCs) to the treaty, gases that are extremely harmful to the climate and used in refrigerators and air conditioners. Experts estimate that if the agreement is respected, it could reduce global warming by 0.5°C by 2100.

Former NASA climatologist James Hansen giving a lecture at the Capitol in Washington in 2008.
Building on the success of the conference on the ozone layer and supported by the leadership of the Minister of the Environment at the time, Tom McMillan, the Mulroney government seized the opportunity and proposed to the UN to organize in 1988 the first major world conference on climate, an issue that was quietly making its way into political circles.
Chaired by Canadian diplomat Stephen Lewis, the UN conference entitled The Changing Atmosphere was held in Toronto in the summer of 1988, a few days after an event that caused a stir on the planet: on June 23, 1988, NASA climatologist James Hansen testifies before the US Senate. He presents the results of his work on the links between increased GHG emissions and warming temperatures.
The expert creates a shock wave. The data from NASA's Goddard Institute for Space Science, which he headed at the time, leaves little room for doubt. The greenhouse effect has been detected and it is already changing our climate, he told American senators bluntly.
TheNew York Times and the Washington Post will be on their front pages.

James Hansen's presentation made the front page of several newspapers.
James Hansen's testimony will provide great momentum to the Toronto conference.
Brian Mulroney will take advantage of this enthusiasm to demand from the international community an international air law, which would be based on the model of the Montreal Protocol. Alongside him, Norwegian Prime Minister Gro Harlem Bruntland proposes the adoption of an international treaty aimed at stabilizing the Earth's atmosphere and preventing further degradation.
The Toronto conference will pave the way for the great Earth Summit in Rio, Brazil, in 1992. This major conference, chaired and masterfully led by Canadian diplomat Maurice Strong, will mark a turning point for saving the climate and of the environment.
Brian Mulroney goes there with his young Minister of the Environment, Jean Charest. But where he plays an important role is in convincing his friend George Bush Sr. to attend. He questions him about the value of this conference without the presence of the United States to encourage him to go there, which Mr. Bush does.
It is in fact at the Rio Summit that the three major international conventions will be born which have today become the backbone of the international protection of the planet: the framework convention on climate change, the convention on biological diversity and the international convention to combat desertification.
It was at the Rio summit that the COP climate process was launched, the aim of which is to enable the negotiation of a global agreement on the issue. COP1 will take place in Berlin in 1995, and the first international climate agreement, the Kyoto Protocol, will be concluded in Japan in 1997.

Brian Mulroney has also defended the Canadian fossil fuel industry.
If Brian Mulroney was convinced of the need to protect the planet's climate, that would not have stopped him from being a great defender of the Canadian fossil fuel industry. Between 1988 and 1993, his government provided more than $2.5 billion in subsidies for the development of the Hibernia oil platform off the coast of Newfoundland and purchased an 8.5% stake in the project.
In 2016, he supported the construction of the Energy East pipeline, which would connect Alberta and New Brunswick, passing through Quebec and under the St. Laurent, to transport Alberta oil to the east coast of Canada. The project will ultimately be abandoned by the developer.
It would have been interesting to hear Brian Mulroney comment on today's environmental issues.
What would he say about the TransMoutain pipeline, which will be in office very soon, bought at great expense by the government and whose construction costs have exploded?
Would he be against the carbon tax, like the is very affirmatively Pierre Poilievre, the current Conservative leader?
Would he support tougher regulations to reduce GHG emissions from the oil and gas industry?
Would he be in favor of the accelerated development of renewable energies to replace fossil fuels? Increasing funding for public transport? The expansion of nuclear energy? To protect 30% of the country's lands and marine areas?
Unfortunately, we will never know the answers to these questions. But what we can say without being too mistaken, however, is that Brian Mulroney probably had within him this sensitivity with regard to environmental protection which pushed him to action rather than resistance. .
He was one of those who were convinced that in the word conservatism, there was also the word conservation.
