“Keeping tree diversity intact in Canada's many forests over the long term can help increase carbon capture & mitigate climate change,” according to a new University of Alberta study.
🧵1/8 Image
The study, published in @Nature, “is the first of its kind to show the sustained benefits of tree diversity on a large spatial scale, in terms of #storing #carbon and nitrogen in the soil. It reinforces the importance of biodiversity conservation in forests.”
The researchers analyzed “Canada's National Forest Inventory database & used statistical modeling to provide new evidence of a link between greater tree diversity & higher soil C & N accumulation in natural forest ecosystems over decadal time scales.”

"A promising solution to nullify the net embodied #GHG emissions of civil infrastructure is the use of C-negative materials for concrete manufacturing. C-neutral coal ash & agriculture/forestry by-products, like #biochar, exhibit a high CO2 uptake potential."
1/8 Image
📝 A lately published paper aimed "to explore the viability of using #biochar as a #CarbonSink and to develop carbon-neutral #concrete with improved performance."
📉 Experimental findings suggest that "the optimal amount of biochar (1%) slightly improves hydration and mechanical properties, but the combination with mineral additives significantly enhances the performance."

A viable & novel formula for a #CarbonNegative, environmentally friendly #concrete that is nearly as strong as regular concrete has been developed recently at Washington State University.


*Summary* in a🧵 below:
1/6 Image
🧫 Researchers exemplify "a synergistic C-capture strategy, i.e., using #concrete washout water & #biochar together to achieve carbon-negative concrete."

"This strategy enabled the biochar to #capture 22.85 wt% air-borne CO2, which precipitated CaCO3 onto the biochar."

🔬"This carbon-negative cement paste consisted of 30 wt% CO2-weathered #biochar and 70 wt% portland limestone #cement, which achieved the 7-day and 28-day compressive strengths of 22.1 MPa and 27.6 MPa, respectively," microscopic investigation revealed.

A new paper shows that mature trees and woodlands are crucial in locking away carbon. Cutting edge laser scanning suggests previous estimates of carbon storage in woodlands could be significantly underestimated. (1/4) #CarbonCapture #Forests
Forests with older, larger trees appear to be especially effective at storing carbon. Scientists warn that "The value you have in large mature trees is almost incalculable, and so you should avoid losing that at any cost." (2/4) #ClimateChange #Trees
Politicians support the 'One Trillion Trees' campaign and advocate large scale planting programmes. However, new planting initiatives are of limited use in comparison to protecting existing forests. Monoculture planting can negatively impact biodiversity. (3/4) #SustainableForest

NEW: Countries' climate pledges put unrealistic demands for land ahead of emissions reductions, which could cause:
🌱Increase abuses of #Indigenous land rights
🌽Food security issues
🌳negative impacts on ecosystems

Read the new #LandGapReport:
Countries' #Climate pledges to get to #NetZero GHG rely partly on removing carbon dioxide from the atmosphere, using methods such as planting trees & restoring degraded ecosystems.

New #LandGapReport revealed that these are schemes unrealistic.

National climate pledges would collectively require 1.2 billion hectares of land.

More than half of this land is already currently used for something else. This demand for land will put pressure on ecosystems, Indigenous lands, small farmers and food security.

(1) Last month, @CAGovernor @GavinNewsom broke his silence on the state climate blueprint with a letter to his own climate regulator @AirResources.

The Governor’s letter urged CARB to go further, faster. Here’s our analysis:🧵
(2) As the McKinney Fire rages red-hot and a megadrought continues, all eyes are on the 2022 Climate Scoping Plan process.

The draft plan has been universally criticized. The Governor’s recommendations, while not legally binding, are important political signals.
(3) Newsom’s notes on the plan:

🥳No new gas plants + funds for offshore wind
🥳 Significant investments in building decarbonization + healthy homes
🚩Likely extend the life of oil refineries with so-called “clean” fuels
🚩Mythic, oversized targets for engineered carbon removal

@jkenney So you expect big govt to pay for questionable emission reduction tech for a profit driven, private industry that’s responsible for most of the emissions🤔How does that make sense? The govt should be investing in renewable tech that doesn’t produce emissions in the first place!
@jkenney Time to scale up that carbon tax for big emitters if this is your solution.
Unfortunately your carbon capture & SNR fantasies are a deflection from real climate solutions & renewable alternatives that are feasible and cost effective. Perpetuating reliance on FF is not a solution
@jkenney #CarbonCapture is a delay tactic that is not conducive to addressing the urgency of ending our reliance on fossil fuels. Does the business model even make sense? Ask Sask Power

The global carbon market is booming, it’s expected to reach $22 trillion by 2050.

So where did it all start?

A thread 🧵 of how a Mormon missionary and a future Reiki Master started it all in the 80’s

#CarbonCredits #CarbonOffset #Netzero
👇 (1/9)
In 1987, Applied Energy Services (@TheAESCorp) planned on building a ~180 MW coal-fired power plant in Connecticut.

The #coal plant would produce ~14 million tons of CO2 emissions over its lifetime.

Global warming was already making some waves & AES was concerned

👇 (2/9)
AES' CEO was former missionary & @HarvardAlumni - Roger Sant @santroger

Rogers’ "least-cost energy" strategy was revolutionary at the time.

@TheAESCorp's focus was minimizing the cost AND #environmental impact of #energy services.

So they needed a “green” solution

As @POTUS signs the Infrastructure Investment & Jobs Act (aka Bipartisan Infrastructure Deal), a quick thread on what it *might* mean for Texas. There could be a lot more funding coming from the #BuildBackBetter package but here’s a look at what’s already passed
#txenergy #txlege
For each section, I have applied 9% of national funding to Texas. BUT, and this should be a question asked of all candidates in 2022, some of these funds are distributed through grants, not formulas.

If Texas doesn’t apply, our tax $ go to other states.
#txlege #txenergy 2/
One part I’ll be watching closely is the $5b in grid resilience funds, $1b per year, half to utilities, half to states. That’s $45m per year for 5 years for Texas to improve grid resilience *if* Texas policymakers pursue it. And another $45m/yr for Tx utilities. #txlege

Carbon capture and sequestration (or CCS) is being touted by some as a potential solution for #decarbonization in industries like cement and steelmaking. But how promising of a solution is it? A deep dive 🧵
There is only limited experience with CCS at industrial facilities beyond gas processing. Only one steel mill in the entire world (and no cement plants), capture CO2. Little info is available about how much they capture, and key info about cost and reliability is missing. Image
Only 3 of 26 CCS projects currently operating in the world have reported any information that would allow their “capture rates” to be determined. Without this information, it’s impossible to show that any existing CCS projects are economically, financially or technically viable.

Today @POTUS unveiled the #AmericanJobsPlan that includes transformative investments in clean energy that could kickstart the economy, create millions of good jobs and tackle the #climatecrisis head on. Here are a few key measures in the proposal [THREAD]
Electric Vehicles: $174 billion to compete in the global #EV market and support American workers to make batteries and EVs, electrify federal fleet, replace 50,000 diesel transit vehicles & work w/ state/local governments to build national network of 500,000 EV chargers by 2030.
Electric School Buses: Electrify at least 20% of US school bus fleet through new Clean Buses for Kids Program at @EPA and set the country on a path to 100% clean buses. Our analysis shows electric buses can have major health, cost-savings & jobs benefits.…

📢 Curious about #carbonremoval?
Read my new report @GlobalCCS: "Carbon Removal with #CCS technologies".

@EUCarbonCapture @Bellona_EU
@cleanaircatf @NEP_Brussels

#carboncapture is a unique set of tech because it has a dual role in addressing #climatechange. It can help to reduce emissions from point sources, AND it can remove CO2 from the atmosphere.

Let that sink in.
There are not many solutions out there that do both.
