Insight, Agriculture & Measurement
One climate venture needs a verification apparatus, a certification chain, and an AI stack to function. Another needs a purchase order. The difference is not technical. It is the distance between the person who bears the cost of change and the person who receives the benefit.
Two climate ventures raised money this month in the same region, in the same week, with the same broad purpose. They have almost nothing else in common, and the difference between them is the most useful thing in the briefing.
Neocrete, a New Zealand company, raised US$3.5m to commercialise an additive that lets lower-quality fly ash and volcanic ash replace roughly 30–50% of the cement in concrete. In Brunei the technology is slated for a deployment of around 65,000 cubic metres at the Muara Port redevelopment, which the company estimates could avoid on the order of 5,200 tonnes of CO₂ while also reducing material costs.
Rize, based in Singapore, closed a Series B in the region of US$31m backed by BNP Paribas Asset Management Alts, the Rockefeller Foundation, Temasek, and Breakthrough Energy Ventures among others. It works with farmers in Vietnam and Indonesia to introduce lower-methane rice-growing techniques, and builds traceability, carbon certification, and AI tools around the value chain.
Notice what Neocrete does not need. No certification chain. No traceability layer. No behaviour-change programme. No verification apparatus at all, in order for the product to be adopted. A contractor buys it because the concrete is cheaper, and the emissions reduction happens as a by-product of a procurement decision that would have been made anyway.
Rize needs all of it. Not because rice is more complicated than concrete, but because of where the benefit lands.
Strip away the sector language and almost every climate intervention can be placed by answering two questions.
How many independent decision-makers have to change what they do?
For Neocrete, effectively one per project: whoever specifies the mix. For Rize, millions, each operating a separate plot under separate conditions.
How far does the benefit sit from the person who bears the cost of changing?
For Neocrete, zero distance. The person who changes the specification is the person whose material bill falls. For Rize, the benefit is a methane reduction that accrues to the atmosphere, is converted into a credit, and is monetised by a buyer in another jurisdiction. The cost is borne immediately by a farmer, in labour, risk, and water management.
That second variable is the one that generates the entire apparatus. Certification, traceability, digital monitoring, and third-party verification exist to carry value backwards across a gap between the actor and the beneficiary. Where there is no gap, none of it is needed.
Which produces a claim worth stating directly, because it inverts how the sector usually talks about this.
MRV is financial plumbing before it is science. That does not make it illegitimate. It makes it something other than what it is usually presented as, and it has consequences for who it gets designed for.
The technique underlying most low-methane rice work is alternate wetting and drying (AWD): allowing a paddy's surface water to drop below the soil line for a period before reflooding, which interrupts the anaerobic conditions that methanogens require. The International Rice Research Institute has documented that AWD can cut methane emissions by roughly 30–70% without a yield penalty in most tested contexts, while reducing water use by around 30%. Rice cultivation accounts for something in the order of 10–12% of global anthropogenic methane emissions on standard inventory estimates, so the prize is large and the technique is not speculative.
There is one honest scientific caveat that gets skipped in venture materials. The more aerobic soil conditions that suppress methane also tend to increase nitrous oxide emissions from the same soil, so a genuine net-warming figure requires measuring both gases rather than the headline one. A lightweight MRV system that measures methane alone will systematically overstate the benefit, and it will do so in the direction that suits everyone being paid.
But the agronomy is not where these programmes fail. The documented barriers are almost entirely social and institutional. The World Resources Institute has catalogued the adoption barriers repeatedly: limits on farmers' control of irrigation water, lack of confidence in the yield outcome, limited direct incentive, and thin information on cost-effectiveness in most rice-growing areas.
Read those carefully, because each one is a different problem wearing the same coat.
A farmer cannot drain a plot that shares a bund and a canal with neighbours who are not draining theirs. AWD requires either individual water control, which most smallholders do not have, or coordination across an entire irrigation block, which is a governance problem involving water-user associations, scheme operators, and social relations that predate the project by generations. No amount of sensor deployment resolves this. It is the same category of problem that decides whether a water scheme functions at all, which is the ground our water-transparency work in Nairobi sits on.
Where irrigation water arrives through a scheme without volume-based pricing, using 30% less of it produces no saving for the farmer whatsoever. The benefit accrues to the scheme, or downstream, or to nobody in particular. One of the technique's two headline advantages simply does not exist for a large share of its intended adopters, and the venture pitch rarely distinguishes between the farmers for whom it does and the ones for whom it does not.
A meta-analytic average showing no yield penalty is a statement about a distribution. A smallholder is not making a decision about a distribution. They are making one decision, once, on the only field they have, with a bad season meaning debt rather than a data point. Rational risk aversion in the face of a favourable mean is not ignorance and it will not be resolved by better extension materials.
Monitoring water depth, walking the plot, timing reflooding: this is labour, and in most rice systems the question of who performs the additional labour has a gendered answer that the household-level survey instrument is not designed to detect.
None of the above is an argument against the model. The combination of practice change, farmer finance, verification, and market access is probably the right architecture for methane reduction in smallholder systems, and a US$31m round with that investor base suggests serious people agree.
It is an argument about what to fund alongside it, and what to require as evidence.
Treat the MRV budget as a diagnostic, not just a cost line. If a venture requires heavy verification and simultaneously projects easy adoption, the two claims are in tension. Heavy MRV is a signal that the benefit is far from the actor, and benefits that are far from the actor do not get adopted without something else carrying the difference. Ask what that something else is, and whether it survives the end of the funding round.
Require the counterfactual to include continuation, not just uptake. Enrolment figures under an incentive measure the incentive. The only meaningful test is what proportion of farmers are still practising two seasons after the payment structure changes. This is unfashionable to measure because it takes years and often produces unwelcome numbers, and it is the single most informative thing anyone could commission.
Insist that net income, not carbon, is a reported outcome. Tonnes are what the credit buyer purchases. Household net income, labour hours, and water access are what determine whether the tonnes keep arriving. A programme that improves the first while quietly degrading the second is not a durable asset, and it will be discovered eventually by someone less friendly than an evaluator.
Separate the verification from the seller. A venture that measures its own outcomes, sells the resulting credits, and reports to its own investors on the quality of its own measurement is being asked to hold three positions at once. This is not a comment on anyone's integrity. It is a structural conflict that independent measurement exists to resolve, and it is far cheaper to build in at Series B than to retrofit after a buyer's due-diligence finds it.
The sector tends to treat verification infrastructure as a technical achievement, and to celebrate its sophistication. It is more useful to read it as a diagnostic reading of the underlying deal. Elaborate MRV means the benefit and the burden have been separated, and separated benefits need continuous machinery to stay connected. Simple adoption means they were never separated in the first place.
Neocrete's proposition works because a contractor in Brunei saves money. The 5,200 tonnes are close to incidental to the decision that produces them, which is exactly why the decision will keep being made. Very few climate interventions have that shape. The ones that do not need somebody, independently, to keep checking that the connection between the work and the reward still holds.
That checking is impact measurement and monitoring and evaluation in the ordinary sense, done by people who go to the plots. The Lab works on it in regenerative agriculture and climate and ecosystems, and our biochar fieldwork in Lombok runs into the same set of questions about who does the extra work and who receives the benefit. It is the same reasoning we applied to electricity volatility in e-mobility markets: find out who is actually carrying the cost, and then check whether they can keep carrying it.
If you are funding an MRV-dependent agricultural programme and want the farmer side measured independently, tell us what you need to know.
