Getting to 2050: Canada's Transition to a Low-emission Future — Advice for Long-term Reductions of Greenhouse Gases and Air Pollutants
Climate change is upon us. Scientific studies are increasingly confident in the assessment of the relationship between observed climate warming and impacts on the earth. They are concluding that a large part of this change is directly related to human sources of greenhouse gases (GHG). [1] Reducing the GHG emissions we put into the atmosphere is central to contributing to the global objective to achieve the stabilization of GHG concentrations in the atmosphere at a level that would prevent dangerous climate change.[2]
Reducing our own GHG emissions means that Canada is facing a transition to a low emissions society – a transition that will be driven by environmental, economic and social factors. We have a substantial national interest in understanding and anticipating the nature and scope of that change and in proactively seeking to manage our response, with respect to both mitigation and adaptation measures, in a way that benefits Canada. This Advisory Report addresses the issue of how to mitigate potential effects of climate change, through deep emission reductions. The National Round Table on the Environment and the Economy (NRTEE) is also working on the issue of adaptation to climate change and will report on this research in 2008.
The Transition to 2050
In the fall of 2006, the Government of Canada asked the NRTEE to look at the issues of national long-term climate change and air pollution policies. Specifically, the NRTEE was asked to provide advice on how Canada could significantly reduce its GHG and air pollutant emissions by 2050. This Reference enabled the NRTEE to build upon its current long-term climate change agenda, in which we had previously assessed a technology scenario for a low-GHG future in 2050. It allowed us to explore the economic and environmental implications associated with such a low-emission future, as well as to start an evaluation of potential policies that may allow Canada to attain its long-term commitments.
The story the NRTEE has to tell is one of transition at many levels – transition in policy, transition in technology, transition in economy, and transition in society. It is a national transformation within the larger context of global change that is to come. Our advice provides a framework through which governments in Canada can seek to manage the necessary change in a way that maximizes economic and environmental benefits for the country.
The federal government - through its Turning the Corner policy statement - has committed to deep long-term emission reduction targets for GHGs and air pollutants. For GHGs, these targets are 20% below 2006 levels by 2020, and 60% to 70% below 2006 levels by 2050. Tackling this challenge will require embarking upon a focused and deliberate transition to a low-emission society. The NRTEE research and conclusions show that, with consideration for some key enabling conditions and acknowledgement of certain risks and uncertainties, this transition is manageable, and may even provide some unique opportunities.

Three core assumptions guided our approach:
Enabling Conditions for Managing the Transition
The NRTEE's research is premised on the federal government's commitment to achieve deep, long-term GHG emission reductions. We acknowledge that achieving these deep reductions poses real challenges given Canada's economic circumstances. But we also recognize that this challenge creates opportunities in terms of innovation and technology development.
It is in Canada's national interest to begin the transition to a low-emission future immediately. This Advisory Report concludes that the government's medium- and long-term targets are achievable. We also conclude that delaying action to reduce GHG emissions comes with economic and environmental risks. One such risk is that, in the absence of a long-term climate change policy framework, energy infrastructure choices being made now will be increasingly difficult and costly to address in the future. On the environmental side, the main risk involves higher cumulative GHG emissions over the time period in question.
To minimize these risks and ensure we achieve our long-term targets, the NRTEE sees the need for five enabling conditions that should be reflected in Canada's climate change policy framework:
A critical point that the NRTEE would like to make, that falls not in the category of enabling conditions but in the category of absolute requirements for Canada moving forward, is that attention must be given to implementation of any policy measures considered and put in place. The mere development of a policy framework for climate change should not be confused with its implementation by government, industry, capital markets, and at the consumer level.
Drawing from the findings and conclusions contained in this report, the NRTEE makes the following recommendations to the federal government:
GHG Emissions
Air Pollutants
For Both GHG and Air Pollutants
Looking Ahead
In order to better understand how to minimize the risks associated with the transition to a low emission society, we suggest that additional policy research be conducted. These issues include:
