Carbon Credit Contract Lengths
มุมมอง 8504 หลายเดือนก่อน
Here I explore contract lengths that are used for forest carbon offsets. Most existing frameworks don't make sense. 100 year long contracts are not desirable for landowners and lead to questionable projects, since the only people signing those contracts are people who wouldn't have otherwise cut the trees. Short contracts only make sense if they extend beyond the biological rotation age of the ...
How to interpret community co-benefits
มุมมอง 5257 หลายเดือนก่อน
Here I talk about how I interpret different types of community co-benefits (primarily in REDD projects). I generally categorize them into: (1) Direct payments (2) Tangible benefits (3) Intangible benefits
Emissions Liability Management: Can an accounting framework fix carbon credits?
มุมมอง 4929 หลายเดือนก่อน
Here I discuss a new accounting framework called Emissions Liability Management (ELM). The idea is simple: companies need to keep balancing their books for all emissions in perpetuity, replacing expired and bad credits with new ones as they come. Although the idea is simple, it comes with some real perks: - By taking greater accountability for their emissions management and revisiting their car...

Verra's new reforestation methodology (VM0047): Good intentions but not good enough. - Corrected
มุมมอง 2K11 หลายเดือนก่อน
Here I dissect Verra's new reforestation protocol. It has some good intentions and ideas, however for a number of reasons, I'm afraid that many projects will continue to just be unadditional timber plantations. NOTE: I added a correction in this video because evidently Verra did create a new rule forbidding non-native mono-cultures. This is very good, although my concerns about the additionalit...
JNR Round 2: Map error, bias, and why bad JNR maps always equal over-issuance
มุมมอง 587ปีที่แล้ว
Here I dive into a more technical explanation as to why I think the overly simplistic JNR risk maps are a no-win scenario. Maps with low bias but high error will always result in landowners with understated risk not enrolling in the program, and project developers finding places on the map that overstate risk. The result is too many credits. Forests that need actual conservation not getting it,...
Verra's Jurisdictional Nested REDD program (JNR): How it works and why it might not.
มุมมอง 2.1Kปีที่แล้ว
Today I want to discuss Verra's new Jurisdictional and Nested REDD program (JNR). This is a new way of calculation baselines that all projects will have to follow in 2025, and it's largely touted as a solution to over-issuance. I briefly walk through how it works; first by creating a state-level estimate of deforestation rates, and then by creating maps of forest risk to say where deforestation...
Leakage Revisited: What concepts are we missing?
มุมมอง 882ปีที่แล้ว
Today I talk a little more about leakage. I bring up several points that might be worth consideration when buying carbon credits. (1) Inverse Leakage - Many carbon projects seem to be restoring or protecting trees outside the project area. This can happen through seed spreading, market leakage, changes in attitudes brought on by the project, or by creating a buffer around some other forest. (2)...
Evolutions in Improved Forest Management baselines; or why VM0045 is the best carbon protocol.

The Climate Action Reserve's Mexico IFM Protocol.
มุมมอง 8632 ปีที่แล้ว
Here I discuss the Climate Action Reserve's Mexico IFM protocol. It has some pros and cons. It's somewhat conservative because it only issues credits for growth. But it has some real additionality loopholes that have allowed people who were already conserving their forests to enroll. Overall 1/3rd of the projects that I've looked at don't seem to be justified. Another large portion are UNDER-cr...

    I really enjoy your videos, I just took some marshmallows while watching this! And I agree in the majority of this, at some points I do not think are SO relevant. One example is adding non-native tree species in a ARR project. I guess it does make sense in a "pure" reforestation without any motivation to make profit with the forest products (nuts, fruits in general) but it doesnt make sense if the non-native tree brings finantial or ecological benefits within the systems, which are the case of agroforest systems. And totally agree with the lack of clarity of the VERRA's methodologies along the text (the sentences are sometimes very dificult to understand even if you are a native english speaker) and the equations are very VERY dificult to get, one case that I took more than a month to understand and still some uncertainties is the performance benchmark methodology in VM0047, the text brings confusion and when you believe you understood and go to the examples, you see you made all wrong! And the worst part is that the examples' values came from nothing and resulted in something, there is no a clarification of the steps needed to achieve the examples' results... Well I'm just getting this off my chest XD You always bring a nice perspective of what is going on around! Thank for making videos like this one!

    Elias, I enjoyed your video. I am a forester in Tennessee. I think your facts are a bit off about clearcutting in Tennessee. We in fact do a lot of clearcutting and we allow natural regeneration to repopulate the tree species composition. The seed source is already on the forest floor. Natural regeneration is responsible for nearly all of forest regeneration.

    Hey Elias, thanks for the video. Curious to know your take on the following: I can understand the benefit of protecting a 50 y.o. doug fir stand for 10 more years if the alternative is deforestation and land use conversion--I don't think there's any question there--but if the land's going to go back into working forest, from a carbon sequestration perspective, wouldn't it make more sense to harvest, lock up that carbon in long-lived wood products, then reestablish that forest to capture more carbon more quickly by taking advantage of the high growth rate of young stands before MAI plateaus off? Thanks!

    What you actually should focus on is why Europeans and Americans as the biggest polluters both currently (on a per capital basis) and historically (on a cumulative basis) are allowed to do this. It is apparent that these would become colonialist projects without the CCB like and SDG impact checks - and these ensure that that doesn't happen. It is but natural justice that Europeans and Americans (the latter in particular) start paying climate reparations (which would be orders of magnitude higher if the math is done right about colonialist and globalist rapacity of the post-Columbian era) - both in the Americas, and in the rest of the world. It is disingenuous to think that communities which preserved their natural assets and contributed so much less to the Climate Crisis will not ask for continued payments (even those unlinked to any kind of offsets). Otherwise very soon the world will ask EU and US to plant in their own backyard and try achieve net zero (and simultaneously go back to stone age level life styles, so never gonna happen). The average Chinese and Indian now alive (to speak of the largest populations ~35% of humanity) - - has 14.4% and 3.3% the cumulative footprint of an American - has 27.7% and 6.3% the cumulative footprint of a (EU) European Why would these two countries even care, leave alone the footprints of LATAM or Africa which are likely also similar or smaller. This is a creation of the "west", they better start paying their dues or suffer the degradation of their profligate lifestyle (the others have less to lose). What you think is a problem - is not so - it is a feature to ensure some buy-in in the absence of many-fold more asks of reparations. You are just a scientist, the world is much more complex beyond that, and the carbon offset prices are just hilariously low, the average price of 1 ton of metallurgical coal (anthracite) equal to ~3.67 tons of CO2 is 3x that of 1 ton of CO2 in the California ETS market (on a t-CO2e basis). Not until the situation is the other way round is this "leakage" going to stop.

    • @eliasayrey5188
      @eliasayrey5188 4 หลายเดือนก่อน

      Well, we should definitely be paying people every year in all projects. But beyond a single year we need to make sure the commitment to conservation/restoration lasts beyond the period that wouldn't have happened. You probably wouldn't want Weyerhauser (the biggest US timber company) to clear cut a forest, then to earn credits for each year that it regrows until they clear cut it the next time. We need to make sure that if they're going to get credits, they commit to protecting the forest for longer than they otherwise would have let it grown.

    Great video. I am an environmental engineering grad student at stanford and this was made well. You said that wood is primarily carbon and hydrogen. 50% hydrogen. if you convert to co2 equivalents then more than the weight of the tree i(in co2 equivalents) is being stored in the tree. I think you must have meant something else as this is not possible.

    Nice content, as usual. Those direct individual payments can be really hard to implement for projects with several thousands of beneficiaries though. Also, households may be lead by men who are known (in some cases) for "misspend" income. Other idea that comes to mind when talking about individual direct payments, for tree planting for instance, is rewards on "performance" or survival of trees as reference for payments' proportion. Not sure about the ethics behind it...

    On mapmaking. If the data is made freely available and the algorithms that gowith them, then I think it is fine toletthe privatesector, and may mean independent third party guys make the maps. They may even make better maps using more elaborate procedures, publish the method and algo, then using much more frequent and intense field survey, check both. Standard and 'independent published', see which does better. I have far less faith in the Big institutions than you do I guess. I also like to see incentives to innovate and get better. I also want to see Africans able tomake maps. None of the institutions you mention are based in Africa .

    The additionality tool would also require a financial analysis to demonstrate that in the absence of carbon finance the plantation would not occur. I am in favor of restoration with native species and that should be promoted. Nonetheless, I've seen several examples where exotic trees monocultures (e.g. in Uganda, Colombia) did improved livelihoods and even biodiversity compared to the baseline scenario was continuation of degraded lands with soil erosion and depriving opportunities for local people....

    I can only speak for Colombia, South America. Verifiers (VVB) are 100% independent, stringent, and not associated with certifiers or registries. They are also heavily regulated by the government. Generalizing over ALL the projects just because they occurred in the USA is again detrimental to all VCM market reliability. So, I like your videos. However, these extrapolations and generalizations are damaging other projects doing even better KPIs than the USA.

    Great video. Thanks, Elias, for shedding light here. Overall, NREF/FRELs bring average uncertainty levels (UL) up to 25 - 30%. That is why it is always best to survey aboveground and underground biomass. You may get UL realistically lower up to 15% and below.

    Great videos and lessons from the temperate forestry science and RS side. However, stating the reforestation with Eucalyptus as a case study as an exotic species in the Brazilian Amazon is doing more harm than good. You should look into Tropical Forest Ecology and re-edit and take off that part. It is a perverse incentive. Eucalyptus, as an exotic, is highly flammable, and the Amazon does not have the soil microbiota to break down their leaves when they fall, among many other ecological damages.

    Thanks for the great explanation. ELM seems an interesting concept and the benefits do resolve some of the heavily criticised aspects of the VCM. For big corps, this adds additional overhead esp. in terms of records management in a heavily resource and capital constrained environment. Will massively stifle adoption. Any solution to grow the VCM in a scalable and transparent manner needs to reduce the burden from the buyers of the credits not add to unfortunately (unless youre microsoft)

    Hey, Mexican CAR developer here. I really like your channel and the criticism to carbon markets is genuinely based on critical thinking. I am sure we will agree more quality will decrease quantity and get offsets to the right price to incentivise que right projects. In the other hand, I think in this case your missing some of the picture. There are a lot of ejidos that have never touched their forest that right know have huge pressure for urbanization, for example Calakmul, second largest tropical forest in the americas, and their tourism boom. I don´t work specifically with IFM protocol. But since there can´t be REDD+ projects in Mexico, the growing pressure for deforestation and the great methodologies Climate Action Reserve has, your picking on the top 10% best projects in the world. Yes there will be bad projects, but 30% sounds too much in this case. For a perfect, additional, forest restoration projects you need a 50 USD offset or modern slavery to achieve them (like the Uganda projects you like). I really like your content but social context is very important to evaluate methodologies and projects, and that might be the hardest par for carbon markets to address.
