Thinking about carbon policy & environmental economics. Often I crash a bike, wipe out on skis, or hook myself. I don't even endorse my own tweets.

If you’re keeping score, ABs TIER OiC amendment adds investment credits that boost supply & push prices down. It also freezes benchmarks, effectively removing tightening rates. With no tightening + investment credits, the credit price might hit $50 in 2030. MOU, bah.

Done right, the Alberta-Canada MOU could increase policy certainty. But delivering on that potential requires fixing the market conditions that have led to a price crash. The Institute’s @enviroeconomics and @dalebeugin explain 🔽 https://t.co/RKsIV6GF9W

You wouldn't know it from the graph, but Canada's economy is more "dynamic" by this measure lmao. That's right! Entry and exit rates are higher in Canada than the US! https://t.co/E2MQJPKIej

"Business dynamism has collapsed across advanced economies. But the drop has been especially steep in Canada. While business turnover in the U.S. declined by 23 percent since the mid-1980s, Canada’s fell by 38 percent." — @AliciaPlanincic

I mean, @nationalpost with canola under pressure from Chinese tariffs, why would we want Canadian farmers to benefit from $1.1 billion in Canadian canola-based biofuels sales (2022-23)? Axe the canola taxola has a nice ring to it...

@enviroeconomics Perhaps not so oddly, one of the places industrial heat pumps could greatly improve energy & carbon efficiency, increase saleable product and increase profits is in the oil and gas sector.

This. Programs to drive industrial heat pumps, improve productivity, spur CDV innovation in globally saleable advanced manufacturing. Global industry needs to decarb and improve efficiency. CDN can deploy at home, innovate, trade, and decarb along the way.

A new study finds that replacing thousands of industrial boilers with heat pumps nationwide could save Americans $1.1 trillion in public health costs and reduce carbon emissions by 1.6 billion metric tons through 2050. https://t.co/3mxXWnhTa4

The +10% ELEC cost would still be cheaper than dirty, expensive, smelly, and hazardous tank of distillate in the basement. With heat waves, many islanders can flip on cooling. Better outcome than $460 of LFO sitting idle in the tank when it’s 32dC outside.

It’s happening.,. PEI utility says it has an “urgent need” to build more fossil fuel-based generating capacity to address the widespread switching from oil furnaces to heat pumps. The initial cost of new generation would push up electricity rates by 10%. https://t.co/6w29PfGPls

Big number, big. And a minimum, when one considers the long range impact of the smoke on human health, in say Ontario.

No base to compare %. The CoBC realistic scenario is worst case; 2030 curtailment shock is covid deep. Our worst case techno-pessimistic, low EIA oil price has 2030 GDP growth down 1.96 to 1.82% - in the range of ECCC and CER. About $12.6B, or equal to the new value from TMX.

And hey @ConfBoardofCda, you need a better approach to model post-2030 impacts. Your current model is not fit for purpose. No boardroom would curtail oil @ close to $800 per tonne with cheaper options available: CCUS, DAC, SMRs, solvents, sodium-ion batteries. Happy to chat.

Looking to 2050, the cumulative $1 trillion ($920B actually) real GDP hit is not discounted. Standard practice is to discount total cost streams, which would roughly halve the estimate. Real GDP removes inflation but does not account for the time preference of money.

And the cumulative AB impact is 78% of all national GDP costs, which is not intuitive given the broad sectoral coverage of the ERP.
