Hello #cdnpoli and #cdnecon! @BrettDolter @GK_Fellows and I have an exciting announcement. We've been working on figuring out the costs of #carbon pricing for Canadian households. 1/?
We are happy to announce the launch of our new, interactive website: You can compare costs by energy source, and different rebate types by province and income decile, and net returns (rebates less costs). 2/?
The rebate types are: lump sum payment, means-tested sales tax (GST/HST) credit increase, sales tax (GST) rate decrease, and increased basic exemption for personal income taxes. 3/?

What’s driving the gas price surge? 1/

@PatAlvarezB chalks it up to these factors: Natural gas prices in Europe may remain elevated heading into the winter amid a tightening supply scenario and below-average storage levels, subdued LNG and pipeline imports.

2/ The run-up in CO2 prices are also a factor: As CO2 prices increase, electric generators are incentivized to operate cleaner burning #gas plants at the expense of coal, which helps to drive gas demand higher and consequently may provide structural support for higher gas prices.
3/ Will the run-up in #gas prices be transitory or enduring? What about #oil? Is the rise in #carbon prices structural?

(1/21) On November 6, 1965, the U.S. agreed with Cuba to airlift Cubans to the United States.

In the next eight years, around 300,000 Cubans took advantage of this program and left for the country that had played a central role in its domestic politics for a long time. 🧵

(2/21) On that very same day, U.S. President Lyndon Johnson's science advisory committee sent him a report entitled Restoring the Quality of Our Environment. 

Summarized in one line: a warning that burning fossil fuels will change the climate.

#science #climatechange 🧵

(3/21) Although the report correctly warned about the increase of carbon dioxide, it noted that it would take a few more years before climate models could reasonably project future global surface temperature changes.

1- Heavy regulations of oil & gas in favor of green energy will only result in greenwashing oil & gas. So many ways to legally greenwash any fossil fuel.

All of this lead to one result: Carbon neutrality will be the mother of all ENRONS: an unprecedented accounting fraud
2- So, what I can do to make my oil or LNG green? There are so many ways... including enriching Elon Musk and Tesla stockholders! Why? Because some corrupt politicians created laws that make it work that way. Anyway, Auto companies are now paying $Tesla to greenwash their cars!
3- People are going to go crazy when they realize what companies can claim in their carbon neutrality accounting systems! Hey, my stores have had skylights since they were built 40 years ago. I have been green all along but I just learned about it!

2019: "a person's average micro-plastic consumption is between 70,000-121,000 particles per yr & rising for those who drank bottled water closer to 100,000."

Imagine plastic inhalation/consumption for those wearing #masks for past yr. #VirtueSignalling…
"Disposable face masks (single use masks) are produced from polymers such as #polypropylene, #polyurethane, #polyacrylonitrile, #polystyrene, #polycarbonate, #polyethylene, or #polyester (Potluri and Needham, 2005)."

They shed. Plastic is inhaled/ingested. By adults & #children.
"This new emergence of #facemasks as environmental litter both in the terrestrial & aquatic environment is a piece of evidence that the global pandemic has not in any way reduced the challenge of increasing #plastic #pollution in the environment."

Friday’s virtual meeting on #climate change between Chinese President Xi Jinping, French President @EmmanuelMacron and German Chancellor Angela Merkel is a good sign not only for the human endeavor of saving our planet, but also for China-EU relations. #ClimateAction Image
Europe has remained a champion for the Paris Climate Accord during the past few years when former U.S. President #DonaldTrump exited the deal. #China made the solemn pledge of having CO2 emissions peak before 2030 and achieving #carbon neutrality before 2060. #ParisAgreement
China and EU being major stakeholders for tackling climate change, collaboration of the Chinese, German and French leadership will be instrumental in materializing what’s written in the Paris Climate Accord. #ParisAgreement #ClimateCrisis

Tell me what you think: are #carbonneutral targets real, or just a form of green washing? 1/5
2. / Do you think companies striving to be carbon neutral will perform better over time?

Here's the performance of the basket since year-end 2017. While the BI Carbon-Neutral Theme Basket outperformed the MSCI ACWI in 1Q, it has trailed (slightly) over a longer-term basis. Image
3./ Will all companies eventually need a carbon target to satisfy #ESG investors?

No real surprise here -- our carbon neutral theme basket has grown over time as more and more companies pledge to become carbon neutral. We currently have 179 companies in the group. Image

1/n A $100m carbon removal @xprize cool! But folks who care about climate should ask some hard questions.

Virgin Earth Challenge $25m prize launched in '07 by @richardbranson. Original prize terms were nonsensical: required a $ bn business to win so the $25m would be meaningless
2/n the Virgin (VEC) prize revamped the terms to say winners had to have pathway to giga scale commercial #CDR, but terms remained deeply ambiguous.

On the plus side, VEC helped us raise funds and attention when I was working to found @CarbonEngineer in '09.
3/n On minus side, the VEC prize diverted resources inside @CarbonEngineer, @Climeworks and other competitors.

@richardbranson and team waited until total funding in space was >> $25 m so impact would have been small, then they punted. Result? Not much.

#Wonk warning: a #thread on social cost of #carbon (SCC). We at @CVEPLLC expected @JoeBiden not just to reinstate higher SCC in his #dayone #climate order but also to look at incorporating #environmental #justice into it.

He did, and it matters. #OOTT /1
Background: when #federal #agencies write rules, they try to maximize net benefits or minimize net costs.

The goal is that adding up all benefits for (and costs to) society + all costs to (and benefits for) regulated parties should be > 0. /2
In this context, SCC offers a way for agencies to “monetize” societal benefits of #climate rules. Oversimplification version: Benefit = (tons of GHG avoided) * (SCC, in $/ton). There are couple of quirks, tho. /3

Short Thread on Canada's New Carbon Tax: 🇨🇦

1- Most of the reduction in the emissions in Europe since late 1980s happened because they shifted them to China & other countries as energy intensive factories & others moved out of Europe.
#Canada #climatechange #oil #OOTT
2- The impact of renewable energy is small. If ALL EU countries switch ALL their cars to #Electricvehciles, assuming ALL electricity comes from solar & wind, they can reduce global emissions by only 2%.
3- European politicians are going to claim great success and show large decline in emissions to justify their massive spending on subsidies to support solar and wind. Although most of it was caused by factories leaving to China. #China #emissions

My most important take-away from the Global #Carbon Budget 2020:

While emissions dropped by an unprecedented 7%, atmospheric CO₂ not only kept growing, it kept growing by pretty much the same amount as in 2019 (+2.5 ppm)

Why? ⬇️
(1) of course atmospheric CO₂ kept growing because we were still emitting massive amounts of CO₂, 34.1 GtCO₂ from fossil fuels plus 5.9 GtCO₂ from land-use change - a similar amount as in 2012, which says something about the fast increase of emissions in the last years

(2) the atmospheric growth rate is the balance between emissions and carbon sinks. Land and ocean absorbed CO₂ from the atmosphere, giving us a 'discount on climate change' - they, presumably the land, might have absorbed somewhat less in 2020 (full budget next year).

.@theAGU hosts a massive conference of Earth and space scientists every December, usually in San Francisco (photos below from previous years). My 1st meeting was in 2003 as a masters' student. In this #thread I'll share highlights from #AGU20, my first time attending virtually! ImageImage
#Agriculture (esp replacing forests with cropland) has been changing the #climate for 6,000+ years. Ancient warming made Europe + East Asia more suitable for cultivation, lengthened Eur. growing season, find @Chris_Kucharik @NRamankutty et al. #AGU20
Something cool I discovered this year at #AGU20 (thanks to @KateBrauman) is the MacGyver session, w/ hacks including a test for #COVID19 in wastewater & a system to lure vineyard pests away with mating calls instead of harmful sprays.…

I’ve spent a lot of time thinking, talking about & worrying about the #PlanningWhitePaper & proposed #PlanningReforms over the last 6 weeks. I’ve seen lots of criticism that I agree with about loss of democratic control, but less about potential impacts on the #ClimateEmergency.
The White Paper presents an alarmingly reductionist view of the role of planning, focusing mainly on the delivery and appearance of houses as individual units, and the appeal of an attractive street-scene, rather than holistically #sustainable design and function of entire places
In a societal sense, this is worrying. How places function must be at the heart of planning, before any consideration of the aesthetics of individual buildings. But from a #ClimateEmergency point of view, this reductionist view is potentially catastrophic.
