Hello, Mr. Chairman and members of the committee. Thank you very much for the invitation to speak today at this critical turning point in the history of Canada's response to climate change.
My name is Dr. Sarah Burch. I'm an associate professor and Canada research chair in sustainability governance and innovation at the University of Waterloo. I'm also the newly appointed executive director of its Interdisciplinary Centre on Climate Change, which is a hub of over 100 faculty, scientists and students who explore the unfolding consequences of climate change and the solutions to it.
I'm a lead author of the United Nations Intergovernmental Panel on Climate Change's sixth assessment report, which, as you know, is currently under way. This is the largest scientific collaboration of its kind, and our assessments directly inform international negotiations on climate change, as well as national, provincial, state and even municipal climate change planning around the world.
As a person who focuses on transitions to low-carbon resilient communities, I'd like to take this time to add my voice to the chorus of scholars, advocates, business leaders, youth, indigenous knowledge holders, and decision-makers who know that Canada can demonstrate real leadership on this issue.
None of this will be new to you, but I'd like to clarify what we know for sure.
We know that climate is already changing. This isn't a problem for other people elsewhere at some distant point in the future. We know that our own activities and the burning of fossil fuels are largely responsible for those changes. There are impacts such as flooding, stress on ecosystems, loss of species, drought, extreme weather events, heat waves and fires, and we are seeing evidence of these impacts now, here in Canada.
This is a human issue, not simply an environmental one. Marginalized communities will suffer the most under a changing climate. We have seen this as the COVID pandemic has unfolded. Pre-existing inequalities were exposed and deepened as a result.
So what do we do?
The ambitions set out in the Paris Agreement will not be met without transformative levels of greenhouse gas reductions in synergy with actions that protect us from the impacts of climate change. Incremental greenhouse gas reductions, such as those obtained through modest efficiency gains in a system still fundamentally dependent on fossil fuels, will not lead to reductions of the pace and scale required to constrain warming to 2°C or less.
As we know, between 1990 and 2019 Canada's total greenhouse gas emissions increased by around 21%, and they decreased by only around 1% between 2015 and 2019. The Intergovernmental Panel on Climate Change, however, has clearly demonstrated that we have to cut emissions in half by 2030 if we're to avoid the most costly and irreversible effects of climate change. Given Canada's historical contribution to greenhouse gas emissions and our exceedingly high per-capita emissions, it's our responsibility to meet and exceed this call by the IPCC.
The U.K. has pledged to reduce greenhouse gases by 78% by 2035, in fulfillment of the statutory obligations laid out in its 2008 Climate Change Act. This is exciting, but it's not what interests me. Much more important is the progress it has made so far: Emissions in the U.K. have fallen by 51% since 1990. Likewise, Germany has committed to reducing its emissions by 65% by 2030, and the U.S. has now recently committed to a 52% reduction below 2005 levels by 2030. The stories behind progress in these countries are more complex than those targets would suggest, of course, but collectively they convey ambition and urgency.
However, targets, as we've seen, are insufficient. They're not in and of themselves action. Specific scalable policies and actions are required to deliver on those targets, along with clear mechanisms for assessing whether we're doing what we said we'd do. We have to hold ourselves accountable.
Furthermore, the cost of unbridled climate change vastly outstrips virtually any estimate of the cost of transitioning to a low-carbon economy. We must, however, recognize that some sectors and communities will bear a larger share of the burden of that transition. In a just transition, the costs of climate change mitigation are shared rather than placed heavily on marginalized communities and workers in certain sectors. These communities can be beneficiaries of the transition to a low-carbon resilient economy rather than collateral damage.
Pulling out specific points in relation to Bill C-12, my suggestions are as follow.
Bill C-12 should set a clear and achievable 2025 milestone so that we know sooner rather than later whether we're making progress. It should legislate a more ambitious emissions reduction target of at least 50% by 2030 to align with IPCC recommendations.
It should make clear who's responsible for reaching objectives and exactly how they'll reach them. There's a crucial missing link between objectives and measures.
It should clearly define a more robust role for the net-zero advisory body to help set this target, as well as review, assess and report on progress.
It should ensure that a just transition is supported federally, explicitly seeking synergies between adaptation, which means protecting ourselves from the consequences of climate change, and mitigation, which means dealing with the causes, while lifting the burden of the transition from marginalized communities.
Thank you.
