Urgent priority is for green banks and public developers to pursue public capture value off the massive solar + storage buildout. There’s added spread from impending loss of ITC.
Won’t happen if they solely prioritize “additionality” or non-market segments in their portfolios.

Or the other way I’ll put it is they fail because they default themselves to only having a portfolio of bad assets.
Yup. Increasing returns demand large portfolios in which higher return assets cross-subsidize lower return assets and minimize project-specific risks.
Municipalization convos too often emphasize lower return projects in housing + energy, ceding market share to the private sector from the jump.

It’s a problem that policymakers so often confuse ‘additionality’ for ‘substitution’ In the green transition. Most technological change is a history of additional technology but it’s in the nature of the ecological crisis that we need 100% substitution with green technologies as a matter of urgency…

Arguments about RECs and arguments about offsets both seem to come down to additionality, but the arguments about RECs aren't phrased that way.
Missing a discussion of additionality seems to miss the key issue.

"Carbon credits are failing to help with climate change - here's why" is a recent paper, published in Nature magazine.
It documents "fatal flaws" with offsets:
🚨 "Hot air";
🚨 Additionality;
🚨 Permanence; and
🚨 Offsets distract from ending fossil fuels.

Climate policy experts call for “excluding or phasing out offsets from carbon-pricing schemes and other climate policy processes”
A call to “act on the science”.

Other than I guess firing Kaitlan Collins or whoever, would the Ellisons be bringing that much additionality in favor of Trump?

The follow on point is - copy and paste my REF whining which isn’t to everyone’s taste here - we’re well passed the point where this stuff is providing genuine overall additionality due to odds/bureaucracy.

Secondly, the écobonus is based on the carbon intensity of (final) production on location and the annual grid mix instead of, for example, the additionality of clean power. The former benefits the French, while the latter would benefit German and EU industries more (as well as Chinese).

YaleClimateConnections: “The hidden risks of forest carbon credits.” Often individuals + companies purchase what are called forest carbon credits. “They’re a way to offset…carbon emissions by paying to plant or protect trees, which absorb and store carbon as they grow.”
![Old growth tree. The organizations that certify these credits have protocols they allegedly use to estimate a project’s impact. The theory: “One credit … should represent one ton of additional carbon dioxide that is stored in a forest.” The reality: “Rebecca Sanders-Demott of the Clean Air Task Force says many projects fail to live up to that promise because of flaws in the protocols.”
Her team found in a recent analysis that many certification programs underestimate the risks of wildfires + diseases, which can obviously kill trees. Another potential problem is the concept of “displacement,” the risk that protecting trees in one area might increase logging in another. [Non-]additionality is when a logging company would replant trees anyway—most often in a monoculture—but then solicits forest carbon credits as another bogus line of revenue. Natural disasters such as wildfires + bark beetles can render a credit worthless by releasing carbon emissions. The certification process may be subject to corruption or regulatory capture; changes of government by election or coup may sacrifice existing protected forest. The Guardian has reported their analysis which showed more than 90% of rainforest carbon offsets from a company named Verra [short for ‘verification’ one assumes] had no positive impact on the climate. Another systemic review of over 2,000 offset projects found that only 12% led to real emissions reductions. A study by REDD+ Projects found that the proportion of worthless credits to be as high as 94%.
For a company seeking greenwashing, realize that it is simply corporate malfeasance to claim to the public + to your customers that it is accomplishing a social good. For an individual, don’t waste your money trying to salve your conscience about the carbon emissions of your next flight overseas. Harsh but true. Consider this tough love + get over it.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:nnq2reoe4aaiyhhtsofqmdrz/bafkreiawbpbf3zanh3mvu7dh2jpwzd3ze2fugl2cpysdqhrl2zhmiy5req@jpeg)

Oh yeah fun story the Carbon market came up with a system (scheme) for "additionality" where if you boost growth rates on say, pine plantations and then it gets harvested, the additional volume is counted as sequestered carbon.
The math is mind-bogglingly suspect and there is a ton of room for fraud

It is an older method, so not sure how much used now. Also, their additionality criteria seems to hinge on addressing this low adoption 5% figure. Not sure where we are at now for EV “penetration” in Canada.

The question about additionality stands, but more importantly, what about the foundational assumptions: 1) All of the carbon in oyster biomass is sequestered from the atmosphere for decades (false - it is respired), and 2) All of the sedimented organic carbon is permanently buried (evidence?).

How to stop undermining gigatonne scale carbon removal
Carbon removal won’t reach gigatonne scale by cutting corners. Standards like permanence and MRV are what unlock trust, investment, and lasting impact.
