When Deals Are Done in Boardrooms, Who Protects the Forests, the Farmers, and the Future?

The Unilever-McCormick merger and the ESG accountability crisis hiding inside a $65 billion deal

There is a particular kind of anxiety that grips responsible investors when a company with a strong sustainability record decides to merge, spin off, or sell. It is not the anxiety of a bad deal. It is the anxiety of watching a hard-won institutional commitment — years of policy-building, supply chain auditing, and public accountability — become negotiable. The question that follows every handshake in a boardroom is one that rarely makes it into the press release: what happens now to the standards?

That anxiety is fully on display in London, Oslo, and Frankfurt right now, as investors in Unilever grapple with the implications of a $65 billion deal that will spin off the British consumer goods giant’s food division and merge it with McCormick, the American spice and condiments company. The transaction — the second largest food deal in history — is bold in its commercial logic. But it has triggered a pointed debate about what happens to Unilever’s sustainability commitments when they move into a company that, by independent assessment, operates to a lower environmental standard.

This is not a peripheral concern. It is, in fact, one of the defining ESG accountability questions of 2026: when corporate sustainability standards travel across a merger, do they survive? Or do they quietly dissolve into the complexity of integration?

The Deal: Scale, Ambition, and a Very Complex Supply Chain

The transaction announced in March 2026 will combine Unilever’s Foods division — home to iconic brands including Hellmann’s mayonnaise — with McCormick’s portfolio, which includes Cholula hot sauce and a global roster of spice and flavouring products. The result will be one of the largest food companies on the planet by revenue, with a supply chain that spans agriculture, commodities, and smallholder farming across multiple continents.

The structure is a Reverse Morris Trust arrangement, giving Unilever shareholders approximately 55% of the new entity, with Unilever itself retaining roughly a 9.9% ownership stake. That retained stake is not insignificant. It means Unilever will remain at the table — a shareholder with both the standing and, theoretically, the leverage to influence how the merged company operates.

McCormick’s new scale: nearly twice its current size post-merger

McCormick will take on oversight of a business nearly twice its current size — a transformation that will fundamentally reshape its supply chain exposure. That supply chain now becomes deeply entangled with agriculture, commodities sourcing, and small-scale farming in ways that McCormick has not previously had to manage at this level of complexity. In practical terms, this means exposure to palm oil, soy, spices, and packaging materials in sourcing regions where land conversion and deforestation risks are real and documented.

The commercial case for the deal is strong. But it is the ESG case — or rather, its current absence — that is making institutional investors uncomfortable.

The Sustainability Gap: What the Numbers Actually Say

Unilever’s reputation on sustainability is not accidental. It has been built over more than a decade of deliberate policy, public commitment, and — critically — public reporting. The company has set explicit no-deforestation targets, published traceability data on key commodities, and maintained grievance mechanisms that allow supply chain concerns to be raised and tracked. These are not decorative commitments. They are the infrastructure of a functioning ESG programme.

McCormick, by contrast, occupies a different position. Hannah Schalk, an analyst at Sustainalytics — one of the world’s leading ESG ratings firms — rates McCormick as a “medium-risk” company on sustainability metrics. The word “medium” carries significant weight in ESG analysis. It does not mean McCormick is irresponsible. It means it has not built the architecture of accountability that investors increasingly require.

“The company’s sustainability report does not include an explicit company-wide no-deforestation commitment, and provides less detail on traceability, auditing and certification.” — Hannah Schalk, Sustainalytics

The traceability gap is particularly concerning. In supply chains involving agriculture and commodities, traceability — the ability to follow a product from shelf back to the plantation or farm where it originated — is not a luxury. It is the foundational mechanism by which deforestation commitments can be verified. Without it, a no-deforestation pledge is a statement of intent, not a verifiable commitment. McCormick, by the assessment of independent analysts, currently lacks this level of supply chain visibility at scale.

McCormick has also acknowledged, in its own reporting, that meeting its indirect emissions and sourcing targets depends partly on improving data collection and supplier engagement across its network. This is an important admission: the company knows the gap exists. The question is whether the merged entity will close it — or simply inherit a larger version of it.

The Investors Pushing Back — and What They Are Demanding

The institutional investor response to this deal has been measured but pointed. Storebrand, the Norwegian asset manager that ranks among Unilever’s top 100 shareholders and also holds McCormick stock, has been explicit about its expectations. Vemund Olsen, its senior analyst, has made clear that the firm will press the combined entity on deforestation-free sourcing — and that this means specifics, not generalities.

What Storebrand is demanding is a framework, not a promise. This includes a clear commitment not to source from deforested or converted land anywhere along the supply chain, a publicly accessible complaints mechanism that allows supply chain issues to be surfaced and investigated, and full traceability of commodities back to their plantation or farm of origin. These are the standards that Unilever has worked toward. They are the standards McCormick has not yet formally adopted.

Union Investment, a Frankfurt-based asset manager and a top-40 shareholder in both Unilever and McCormick, has also signalled its intention to seek transparency about how the merged entity will integrate sustainable practices going forward. The language is diplomatic. The message is not: show us the plan, or we will make our concern heard.

As You Sow, the U.S.-based shareholder advocacy group, has framed the stakes in the starkest terms. Cailin Dendas, its environmental health programme coordinator, has drawn an explicit parallel with the Kellanova-Kellogg separation of 2023 — a case study in what happens when a merger or spin-off results in sustainability commitments being quietly abandoned.

“If Unilever-McCormick decide to turn their backs on sustainability, this could create significant risk for shareholders and the new entity. We saw this happen when Kellanova separated from Kellogg in 2023 and dropped its pesticide commitments, among other sustainability goals.” — Cailin Dendas, As You Sow

The Kellanova warning is not abstract. When Kellogg’s split produced Kellanova as a standalone entity, sustainability commitments that had been embedded in the parent company’s culture did not automatically transfer. They required active recommitment — which did not always come. Investors who had priced Kellogg’s ESG posture into their valuation found themselves holding a company with a materially different risk profile than the one they thought they owned. The lesson is direct: corporate restructuring is an ESG risk event, not just a financial one.

The Regulatory Asymmetry: A Deliberate Accountability Gap

One of the structural vulnerabilities in this deal is regulatory. McCormick is headquartered in Hunt Valley, Maryland. Under U.S. rules, it is not required to publish the same level of detailed sustainability information that UK-based Unilever faces under European regulatory frameworks. This is not a technicality. It is a structural accountability gap that the merger threatens to exploit — not necessarily deliberately, but by default.

European companies with significant operations are expected to comply with EU-level sustainability reporting requirements, including supply chain due diligence and emissions disclosure. The new combined entity, while inheriting Unilever’s European exposure, will be structured around McCormick’s American regulatory baseline. Compliance with European standards may take years to fully embed in the merged organisation — and in that transition period, disclosure standards will depend almost entirely on voluntary company commitment.

Voluntary commitment, in the absence of regulatory compulsion, is precisely where ESG standards most frequently erode. This is not a cynical observation. It is the documented pattern across multiple sectors and multiple jurisdictions. When the legal floor is removed, only culture and investor pressure remain. And investor pressure, while real, is not always sufficient to hold the line.

This regulatory asymmetry also has implications for Africa. Unilever’s African supply chains — spanning agricultural sourcing in West, East, and Southern Africa — have historically operated under the discipline of Unilever’s global sustainability framework. Smallholder farmers in Nigeria, Kenya, Ghana, and Côte d’Ivoire who supply ingredients into Unilever’s food value chain have, in theory, been covered by the traceability and audit commitments that Unilever has made publicly. Whether those protections survive the transition to McCormick’s operational model is a question with real human consequences.

What This Means for Africa: The Smallholder Farmer Question

There is a dimension to this deal that the investor conversations in London and Oslo rarely foreground, but which carries significant weight from an African development and accountability perspective. The expanded supply chain that McCormick will inherit includes deep roots in African agriculture. Spices, agricultural commodities, and food ingredients sourced from African farms are a substantive part of the value chain that this deal brings together.

African smallholder farmers — who make up the majority of agricultural producers in the supply regions feeding into global food company chains — are the most exposed to the consequences of weakened ESG commitments. They do not have access to the boardrooms where this deal is being structured. They do not appear in the Reuters reports or the investor letters. But they are among the most materially affected parties.

When a multinational food company reduces its traceability requirements, smallholder farmers lose the visibility that protects them from being excluded from supply chains for failing audits they were never supported to pass. When no-deforestation commitments weaken, pressure on land in frontier agricultural regions increases. When grievance mechanisms disappear, workers and farmers have no channel through which to raise labour rights or environmental concerns. These are not hypothetical risks. They are the documented consequences of weakened ESG governance in agricultural supply chains across Africa.

The African context makes the investor pressure on this deal not just commercially rational but morally necessary. ESG accountability is not a First World luxury. It is a development imperative.

Unilever’s Response — and Why It Falls Short

Unilever’s public response to investor concerns has been carefully worded. A company spokesperson told Reuters that the company is “working closely with McCormick ahead of the completion of the transaction to support the transition of our Foods-related sustainability programmes and commitments.” It is a sentence that is designed to reassure without committing. Working closely with. Support the transition of. These are process words, not outcome words.

What investors are asking for is different. They want to know whether the combined entity will formally adopt Unilever’s no-deforestation standards as binding company-wide commitments. They want to know whether traceability systems will be extended to McCormick’s supply base, and on what timeline. They want to know whether the grievance mechanisms that Unilever has maintained will be preserved and accessible in the new structure. None of these questions have been answered with the specificity that the situation requires.

McCormick’s own response has been similarly non-committal. “While we cannot comment on future targets at this time, we are already well underway on a comprehensive strategic update process for our sustainability programme, and we’ll share more details on our approach as the process unfolds,” the company said. This is the language of a company buying time. It may be legitimate — integration is complex, and strategy reviews take time. But it is insufficient for investors who need to make decisions now about the ESG risk profile of their holdings.

The gap between what has been said and what needs to be committed to is, itself, the accountability problem. In CSR and ESG, the space between a vague intention and a verified commitment is where impact goes to die.

The Broader Pattern: ESG Commitments as Merger Casualties

The Unilever-McCormick situation is not an isolated case. It is part of a pattern that has become one of the most significant structural risks in ESG investment: the dilution of sustainability standards through corporate restructuring. Mergers, acquisitions, spin-offs, and joint ventures consistently create moments of ESG vulnerability — points at which commitments made by one legal entity do not automatically transfer to its successor.

The Kellanova-Kellogg case that As You Sow has cited is one example. There are others. When Allergan was acquired by AbbVie, sustainability commitments embedded in Allergan’s culture required active recommitment from AbbVie’s leadership — and some did not survive the transition. When large resource companies divest assets to smaller operators, environmental commitments frequently weaken because the acquiring entity lacks the internal capacity or investor pressure to maintain them.

This pattern suggests that ESG due diligence in M&A processes needs to be treated with the same rigour as financial, legal, and operational due diligence. Currently, it is not. Sustainability commitments are often treated as soft considerations — important for optics, but negotiable in the details of deal structure. The investor pressure on the Unilever-McCormick deal represents a meaningful effort to change that norm. If it succeeds — if the combined entity emerges with stronger, not weaker, sustainability commitments — it will set a precedent that could reshape how ESG is handled in future food sector transactions.

If it fails, it will confirm what the cynics already believe: that ESG is a fair-weather commitment, maintained when it is easy and abandoned when it becomes inconvenient.

What Best Practice Should Look Like — A Framework for Post-Merger ESG Accountability

The Unilever-McCormick deal presents an opportunity to demonstrate what genuine ESG accountability looks like in the context of a major corporate transaction. For that to happen, the combined entity needs to commit — publicly and specifically — to the following:

• A formal, company-wide no-deforestation commitment that is binding on both the legacy Unilever Foods supply base and McCormick’s existing supplier network, with a clear implementation timeline
• A supply chain traceability programme that maps commodities — including palm oil, soy, spices, and agricultural inputs — back to the plantation or farm of origin, with public reporting on coverage and gaps
• A publicly accessible grievance mechanism through which supply chain workers, farmers, and community members can raise environmental and labour rights concerns
• Independent third-party auditing of sustainability claims, with results published on a regular schedule
• Alignment with EU-level sustainability reporting standards — not as a regulatory minimum, but as a voluntary floor that reflects the combined company’s global footprint
• A specific commitment on smallholder farmer support, particularly in African and Asian sourcing regions, to ensure that sustainability requirements do not become barriers that exclude small producers
• A board-level ESG accountability mechanism that gives investors ongoing visibility into sustainability performance post-merger

These are not aspirational standards. They are what Unilever’s investors already expect — and what the merged entity must now demonstrate it can maintain at scale.

The Verdict: A Test for ESG in the Age of Mega-Mergers

The Unilever-McCormick deal is, by any measure, a landmark transaction. Its commercial logic is clear. Its financial structure is sophisticated. Its brand portfolio is genuinely impressive. But none of that changes the fundamental accountability question that hangs over it: will the sustainability commitments that Unilever has spent years building survive the transfer to a company that, by independent assessment, operates to a lower environmental standard?

Investors are right to press. The forests are right to require protection. The farmers are right to expect continuity of the standards that govern the supply chains they operate in. And the public is right to demand that a $65 billion deal does not become a $65 billion ESG regression.

What this deal ultimately tests is whether ESG has moved from a reputational asset — something companies maintain because it looks good — to a structural commitment that survives the commercial pressures of deal-making. The answer will emerge not in press releases but in the specific, binding, independently verifiable commitments that the combined Unilever-McCormick entity either makes or fails to make in the months ahead.

CSR Reporters will be watching. So will the forests of West Africa, the smallholder farmers in South Asia, and the institutional investors who have placed sustainability at the centre of their decision-making. The question is whether the companies involved will rise to the moment — or whether this will become another case study in how responsible business rhetoric ends at the signature line of an acquisition agreement.
