National, provincial and territorial governments throughout Canada have applied a myriad of insurance policies to cut back greenhouse fuel emissions lately. However, these stubbornly excessive emissions have solely simply began exhibiting indicators of falling.
In precept, every degree of presidency is working towards the identical aim. Yet, the approaches they use differ in effort, design and protection — with some emissions sources lined by a number of insurance policies whereas others stay unregulated.
To obtain our emissions objectives, we’d like federal, provincial and territorial insurance policies paddling in the identical course along with synchronized efforts to maximise our influence.
In our new research, not too long ago revealed in Climate Policy, we study the event and design of local weather coverage mixes throughout Alberta, British Columbia, Ontario and Québec, in addition to on the federal degree, and consider their anticipated influence on emissions abatement.
Regulatory sticks over coverage carrots
Over the final 20 years, the quantity and sorts of local weather insurance policies applied in Canada and globally have expanded dramatically.
Policy “carrots” — financial incentives, resembling subsidies for low-carbon applied sciences — are by far the commonest coverage sort and have additionally been discovered to be extra politically common. But, it’s the obligatory laws — the regulatory “sticks” — together with carbon pricing and versatile laws which are anticipated to do many of the heavy lifting.

While the elevated effort towards implementing local weather insurance policies throughout jurisdictions is nice, synchronized coverage choices are higher.
We see many situations of overlapping insurance policies throughout provinces that may help or undermine our emissions discount aims. Most coverage interactions (74 per cent) assist cut back further emissions. For instance, incentivizing electrical car adoption whereas decarbonizing our electrical energy grid can create higher emissions discount than both coverage can by itself.
However, interactions between overlapping insurance policies — notably throughout provincial/territorial and federal ranges — can even result in unintended penalties that undermine our coverage aims.
For occasion, electrical autos earn credit underneath the federal car emissions requirements in extra of their precise emissions depth (previous to coverage adjustments coming in 2025).
This can imply that when further provincial insurance policies incentivize the adoption of electrical autos, like B.C.‘s zero emission car gross sales mandate, they permit even increased emissions intensities from the remainder of the car fleet whereas nonetheless assembly the federal normal. This can lead to a web enhance in emissions.
Need for synchronized local weather insurance policies
Understanding how insurance policies work collectively is critically necessary.
Consider the case of Canada’s various approaches to carbon pricing. When further insurance policies are imposed to cut back emissions from fuels lined by the federal carbon tax, the motivation from the carbon worth provides on to the motivation from the opposite coverage.
This is as a result of the rise in value of upper polluting items from the carbon tax doesn’t change within the presence of further coverage. For instance, in British Columbia, fossil gasoline use for transportation is disincentivized by each the province’s carbon tax and low-carbon gasoline normal.
However, the interplay differs when the extra insurance policies to cut back emissions are additionally lined underneath a cap-and-trade program. Cap-and-trade applications set a restrict on the whole greenhouse fuel emissions from regulated sectors resembling electrical energy, transportation and heavy trade.
A set amount of emissions allowances are then allotted or auctioned to companies by the federal government. These allowances are then used to account for that agency’s greenhouse fuel emissions. This is seen within the provinces of Québec and Nova Scotia, for now.
Additional insurance policies can cut back emissions from sectors lined by the cap and with it, the demand for emissions allowances. This makes it simpler to attain the restrict set by the cap. However, because the restrict set by the emissions cap stays unchanged, further insurance policies don’t essentially contribute to any further emissions discount, however merely shift prices and emissions between actions.
Such interactions have necessary implications for the way we examine the stringency of carbon pricing techniques throughout Canada in relation to the federal benchmark.
Provinces throughout the nation differ of their financial construction, entry to vitality assets and political ideologies. So it’s no shock that various coverage approaches are being pursued.
For occasion, Alberta, which relied on the oil and fuel sector for practically 25 per cent of GDP and 10 per cent of presidency income in 2019, has applied about half the variety of insurance policies as the opposite provinces studied.
However, making certain insurance policies work collectively to attain our objectives requires higher co-ordination and co-operation throughout, and between, governance ranges. Re-invigorated inter-governmental our bodies just like the Canadian Council of Ministers of the Environment supply a path on this course.
The number of insurance policies applied throughout the nation additionally spotlight the significance of evaluating coverage decisions inside the context of the broader coverage combine — a key consideration for local weather accountability our bodies such because the Net-Zero Advisory Body and B.C. Climate Solutions Council.
We are all in the identical boat. And if everyone seems to be paddling in their very own course, we will veer off track and make it even tougher to achieve our vacation spot. To propel us effectively in direction of our emissions targets, insurance policies and applications throughout nationwide and provincial jurisdictions must paddle collectively.
