Zefiro Methane Corp. (ZEFI) announced that its subsidiary, Plants & Goodwin, Inc. (P&G), has successfully completed its first gas well remediation project in Oklahoma. The project involved a complex operation known as “plug and abandonment” on a deep gas well in Custer County, Oklahoma. The well, 15,000 feet deep, required the removal of 5,000 feet of casing to seal it permanently. This operation is expected to generate carbon offset products approved by the American Carbon Registry.
Zefiro Methane’s Founder and Chief Executive Officer Talal Debs commented,
“Too many Oklahomans and Americans living across the south-central United States are still forced to navigate the public health threats posed by these vestiges of a bygone era. The completion of this project not only represents Zefiro’s successful entry into a key marketplace but also reinforces the Company’s forward momentum and total commitment to executing our growth strategy by helping more of our neighbors combat this legacy issue.”
Unplugged Wells: A Major Challenge Across the U.S.
For decades, fossil fuel companies in the United States have drilled oil and gas wells to boost production, consumption, and exports. Once these wells become unprofitable, they are often abandoned. Many are left unplugged or improperly sealed, leading to environmental risks and fueling climate change.
Zefiro Methane’s press release explained that in the U.S., millions of oil and gas wells remain unplugged. For example, Oklahoma has about 18,000 known abandoned wells, while Texas and Louisiana have thousands more.
- Experts estimate it could cost up to $158 billion just to plug the suspected 1.14 million unplugged wells in these three states alone.
- Nationwide, sealing all abandoned wells could cost as much as $435 billion.
Dangerous Methane Source
Abandoned and unplugged oil and gas wells are leaking methane which is a potent greenhouse gas. Methane is 25X stronger than carbon dioxide at trapping heat and is a powerful contributor to global warming. This gas causes climate change, pollutes water, and is harmful to human health.
- An ESSI (Environmental and Energy Study Institute) study revealed that the EPA estimated, in 2018, abandoned wells released 290 kilotons of methane which is equal to burning over 16 million barrels of oil. Experts warn that rapid action is needed to cut methane emissions and avoid severe climate impacts.

Financial Burden on States
Unplugged oil and gas wells create significant environmental and financial risks. When these wells become orphaned, meaning abandoned without responsible parties, they pose a burden on taxpayers with the costly cleanup. The responsibility to manage these wells falls on the states. Moreover, funds from industry fees and bonding requirements might not cover the costs.
Due to improper management, they release harmful pollutants, leading to air pollution, groundwater contamination, and degraded soil quality. These environmental impacts are highly detrimental to ecosystems, wildlife, and the land.
Safety Hazards
Another significant hazard of these unplugged and abandoned wells is the risk of explosions. It then becomes a persistent threat to both communities and the environment. Thus, addressing these wells is crucial to minimizing their long-term impacts.

Let’s see what other leaders of Zefiro Methane remarked on this project.
Zefiro’s Chief Commercial Officer Tina Reine commented,
“Now more than ever, investors throughout the international voluntary carbon marketplace are seeking offset products that can immediately help clean up our critical air, land, and water resources. The expertise of the oil and gas well remediation specialists on this project have further diversified both Zefiro’s operational presence and unique portfolio of high-quality, verified carbon credits, and our entire team cannot be more excited to continue meeting this long-unaddressed sector demand.”
Senior Vice President of Business Development and Chief Executive Officer of P&G Luke Plants commented,
“The Custer County project is the largest leap forward that our environmental remediation and carbon markets teams have taken together to help solidify Zefiro as the methane abatement sector’s leading comprehensive service provider. This successful effort is indicative of our environmental service division’s drive to help plug more of these wells throughout the south-central United States and in every corner of the country by expanding technical capacity, making operations even more efficient, and helping generate high-quality carbon credits.”
Zefiro Methane Credits: Maximizing Climate Impact
Zefiro also noted that its methane abatement credits deliver immediate and impactful climate solutions. As said before, methane has a significantly higher global warming potential than CO2 and has contributed to 30% of global temperature rise since the Industrial Revolution.
By focusing on methane reductions, Zefiro provides high-value credits that have significant demand for their ability to create measurable environmental benefits. These credits not only help bridge the gap for companies striving to meet net-zero goals but also play a crucial role in tackling the urgent challenge of climate change.
Expanding into New Regions
All said and done, the company is tackling the unplugged abandoned wells crisis seriously. It recently launched operations in West Virginia and acquired companies in Ohio and Pennsylvania to strengthen its capabilities nationwide. The company has partnered with federal and state agencies, including the National Park Service and the Commonwealth of Pennsylvania, to seal orphaned wells.
Additionally, it plans to expand its remediation efforts into other southern states like Texas and Louisiana within the next year. These regions also harbor thousands of abandoned oil and gas wells, many of which are not yet properly sealed.
By addressing methane leaks, which trap heat 25 to 85 times more than carbon dioxide, Zefiro is protecting communities and combating climate change efficiently.

Climate-Linked Supply Chain Risk Is Already in Your P&L
The earnings calls that quietly reframed climate from sustainability question to operating risk.
Three earnings calls in the last 18 months tell the story without any help from a press release.
Hershey, May 2024: cocoa price exposure compresses margin, and the company attributes part of the cost shock to West African weather. Olam, July 2024: coffee climate exposure quantified in the annual report. JBS, January 2025: supply chain climate disclosures expanded materially in response to investor pressure and regulatory expectation. None of these companies issued the announcement as climate news. They issued it as financial news. The climate-linked supply chain risk did not arrive with a sustainability framing; it arrived as a P&L line.
You are probably reading this article because you suspect the same thing is happening to your business. This piece walks through what is showing up on which earnings calls, how procurement and finance leaders are quantifying the exposure, and what serious corporates are doing about it before the regulator asks.
Where climate risk has already appeared in earnings
The pattern is consistent across resource-intensive sectors. A weather event compresses supply, the price spikes, the cost flows through the income statement, and the analyst on the call asks whether the event is anomalous or structural. Increasingly, the honest answer is the second one.
Cocoa is the cleanest example. The 2023 to 2024 West African harvest fell sharply on the back of erratic rainfall and disease. Cocoa futures more than tripled. Companies with concentrated West African sourcing absorbed the cost; companies with diversified sourcing absorbed less. The exposure was not climate as ESG topic. It was climate as cost of goods.
Coffee follows the same pattern. Brazilian and Vietnamese harvests have moved on weather more sharply across the last several seasons. Roasters with long-tenor supplier relationships and origin diversification have managed the volatility; roasters with spot-market exposure have not. Wheat, sugar, palm oil, beef: the same dynamic in different commodities, a pattern the IPCC AR6 Working Group II report projects will intensify across agricultural systems through mid-century.
What this means: climate risk is no longer a footnote in the 10-K. It is a line item the CFO has to explain on the call.
The three commodity exposures that hit margin first
For most companies with material Scope 3 exposure, three exposures dominate the near-term P&L risk.
- Concentrated single-origin sourcing in a climate-vulnerable region. If your tier-one supply for any material commodity sits in one geography, you have a concentration risk that climate amplifies. Diversification across origins is the obvious hedge, but it takes years to build and requires relationships you cannot acquire by tender.
- Supplier financial fragility under climate stress. Smallholder farmers, who supply a large share of the global cocoa, coffee, and palm oil market, do not carry the balance sheets to absorb yield shocks. When yields collapse, they exit. When they exit, your supply base shrinks, and the surviving suppliers raise prices. The risk is structural, not cyclical.
- Logistics and storage exposure to extreme weather. Hurricane disruptions to Gulf shipping, drought-driven Panama Canal restrictions, flooding in European inland waterways: each of these has moved input costs in the last three years, a pattern documented in Munich Re’s natural catastrophe data. The exposure shows up as a one-quarter event in the financial press but accumulates over time on the cost line.
TCFD and ISSB disclosure changes
The disclosure architecture has now caught up with the risk. The Task Force on Climate-related Financial Disclosures, whose recommendations are now embedded in the ISSB’s IFRS S2 climate standard, requires companies to disclose climate-related risks across physical and transition categories, with quantification where possible.
For physical risk specifically (the climate-linked supply chain risk you are reading about), the disclosure must address both acute exposures (extreme weather events) and chronic exposures (gradual changes in temperature, precipitation, and growing seasons). The disclosure must address the time horizon over which the risk is material, the parts of the value chain exposed, and the financial impact under different scenarios.
The CSRD imposes similar requirements under European law, with double materiality (both financial and impact materiality) embedded in the assessment. The practical effect: your auditors and your investor relations team now need a defensible answer to the climate-linked supply chain risk question, and the answer needs to be quantified.
What procurement and finance can do now
Three actions matter near-term.
Map your exposure. Most companies do not have a clear view of which tier-one and tier-two suppliers sit in which climate-vulnerable geographies. Without the map, you cannot quantify the risk, and without the quantification, you cannot disclose it credibly. The map is the foundation, and World Resources Institute climate risk research provides useful public tooling to start.
Diversify and deepen, in that order. Diversification across origins reduces concentration risk, but the deeper move is to invest in the resilience of the suppliers you already have. Regenerative practices, agroforestry, soil health interventions: these reduce yield volatility under climate stress and protect your input cost trajectory.
Embed the climate spend inside procurement, not outside it. Treating climate risk as a sustainability cost line subordinates it to the ESG budget. Treating it as a procurement and resilience investment puts it in the budget that matters, which is the cost-of-goods budget that the CFO defends quarterly.
Nature-based supply chain investments are the asset class designed for exactly this purpose. They sit inside the value chain, they reduce climate-linked supply risk, they generate verifiable Scope 3 reductions, and they produce the documentation an auditor and a regulator can both test.
If you are quantifying climate-linked supply chain risk in advance of the next earnings cycle or the next disclosure period, the carbon and sustainability experts at Carbon Credit Capital can help you map your exposure and structure a Dual-Value Model response that addresses reduction, resilience, and disclosure-readiness in a single program.

Carbon Footprint
Where should an SME start with a carbon action plan?
More and more small and medium-sized businesses are hearing the same question from their larger customers: What is your carbon footprint? That question now travels down entire supply chains, and it arrives next to tender requirements, certification criteria, and rising customer expectations.

Insetting vs Offsetting: Which Actually Counts Toward Your Scope 3 Targets
The accounting differences that decide whether your nature investment shows up in inventory, in BVCM, or nowhere at all.
The question reaches a procurement team about three weeks before the next sustainability committee meeting. Someone has read about insetting. Someone else has just signed off on an offset purchase. The CSO wants to know if the two are interchangeable. The answer is no, and the GHG Protocol Land Sector and Removals Standard is the reason why.
This article walks through what each term means at audit-grade specificity, what the standards actually say about how each gets counted, and how to decide which tool fits which target. The insetting vs offsetting question is one of the most-searched in corporate climate strategy, and one of the most poorly answered. By the end of this piece, you should be able to brief a committee on the difference without notes.
The two definitions, in plain English
Offsetting means buying carbon credits generated outside your value chain and retiring them against your residual emissions. The reduction happens somewhere else, financed by you, and the credit is the receipt.
Insetting means investing in emission reductions or removals inside your own value chain, typically with suppliers, where the reduction is directly linked to the products and services you buy. The reduction happens inside the boundary of your Scope 3 inventory, and the accounting treatment is fundamentally different.
The shorthand from the University of Oxford’s Nature-based Insetting Initiative is useful: insetting is what you do with the supply chain you have; offsetting is what you do with the supply chain you do not have.
What the GHG Protocol Land Sector Standard actually says
The GHG Protocol Land Sector and Removals Standard, finalised in 2024 after a multi-year pilot, sets the rules for how land-based emission reductions and removals enter corporate inventories. The Standard distinguishes between inventory accounting (Scope 1, 2, and 3) and project or intervention accounting (a separate methodology for crediting).
For insetting, the practical implication is that supplier-level interventions, when properly measured and attributed, can reduce your Scope 3 category 1 (purchased goods and services) emissions in your inventory. The reduction is not a credit retired against the inventory; it is a lower inventory number, period.
For offsetting, the credit is retired separately. It can be reported as a contribution toward a net-zero claim under the SBTi Beyond Value Chain Mitigation framework or as part of a VCMI Carbon Integrity claim, but it does not lower the inventory number.
A practical consequence: if your Science Based Target requires a 50% absolute reduction in Scope 3 emissions by 2030, insetting moves you toward the target. Offsetting does not. This single point of difference reshapes the procurement decision.
When insetting counts toward Scope 3 (and when it does not)
Insetting counts toward Scope 3 only when several conditions are met:
- The intervention must occur with an entity in your value chain.
- The emissions reduction or removal must be measured against a defensible baseline.
- The reduction must be attributed to your share of that supplier’s output, not double-counted with other buyers.
- It must follow the inventory accounting rules in the GHG Protocol Land Sector Standard, not the project accounting rules used to generate credits.
The most common failure mode is double counting. If your supplier sells the same reduction as a credit on the voluntary market and also reports it to you as a Scope 3 reduction, the math breaks. The Standard requires you to address this risk, typically by purchasing and retiring the supplier-issued credit as part of your inventory or by contractual provisions that prevent the supplier from selling the reduction twice.
When insetting does not count toward Scope 3: when the intervention sits with a supplier you do not buy from, when the baseline is not defensible, when the attribution is unclear, or when the documentation does not survive audit. Those cases default to Beyond Value Chain Mitigation, which is still useful but operates on a different ledger.
The procurement and supplier engagement question
Insetting is harder than offsetting. That is the unfashionable truth most buyers eventually confront. Offsetting is a transaction; insetting is a relationship.
To run an insetting program, you need supplier mapping precise enough to know which farms or facilities sit at which Scope 3 boundary. You need an engagement model that gets suppliers to participate, which usually requires multi-year commitments and shared economics. You need an MRV architecture that measures the right things and produces audit-ready documentation. And you need a contractual structure that prevents double counting and protects both sides.
The trade-off you receive in return is significant. Reductions count against your inventory rather than your residual. Supplier relationships deepen, which protects sourcing continuity. Yield and quality improvements often follow regenerative interventions, which reduces your input cost over time. And the regulatory file, under CSRD, CSDDD, EUDR, and the SBTi FLAG Guidance, is materially stronger.
Choosing the right tool for the right target
A practical decision rule. If your target is a science-based Scope 3 reduction and you operate in a FLAG sector or source FLAG commodities, insetting is the structurally correct tool. If your target is a net-zero claim that includes neutralising hard-to-abate residual emissions outside your value chain, BVCM via high-integrity offsets is the structurally correct tool. Most companies with material Scope 3 exposure need both, in different proportions, sequenced over time.
The sequencing matters. Insetting takes longer to stand up but produces a permanent reduction in the inventory. Offsetting can be transacted faster but does not change the inventory and now sits under tighter claim restrictions. Treat them as complementary tools with different jobs, not as substitutes. The Accountability Framework Initiative and the IUCN Global Standard for Nature-based Solutions both provide useful guardrails for the insetting side, with biodiversity, human rights, and benefit-sharing requirements that go beyond carbon math.
If you are mapping a Scope 3 reduction roadmap and need to scope which interventions count toward your inventory versus which sit in Beyond Value Chain Mitigation, the carbon and sustainability experts at Carbon Credit Capital can help you structure a nature-based supply chain investment program that fits your FLAG exposure, your target architecture, and your audit horizon.
