01
Disclosure & Reporting Readiness
Mapping which sustainability and climate-related disclosures are mandatory for a company's structure and markets, then building reporting that can withstand regulator and investor scrutiny.
Corporate & Business Law
ESG & Sustainability Advisory
Sustainability handled as a governance and disclosure discipline, with board oversight, reporting that withstands scrutiny, and claims a company can substantiate under the US, UK, and EU regimes a global business answers to.
A published sustainability commitment is a representation, and the law now treats it as one. The FTC's Green Guides treat an unqualified "eco-friendly" as deceptive because it implies more than any seller can prove, and from September 2026 the EU bars claims that a product is climate neutral where the claim rests on offsets. The exposure is the gap between what was said and what the records show.
Which regime binds a company turns on its listing, its EU revenue and its UK footprint, and the EU thresholds have been moving since 2025. A UK business with turnover of 36 million pounds or more publishes a modern-slavery statement every year; a US importer must rebut, at the port, the presumption that goods with inputs from Xinjiang were made with forced labor. We map which rules are mandatory and which commitments prior statements and contracts have made binding.
What is disclosed should match what is true, what is promised should be substantiated, and what the board oversees should be documented. Where a matter turns on jurisdiction-specific regulation or a technical assessment, we coordinate with the appropriate technical adviser or locally admitted counsel so the advice holds where it is given.
What we do
ESG and sustainability counsel for companies, boards, and investors, from disclosure readiness through governance, diligence, and sustainable-finance structuring.
02
Board Oversight & ESG Governance
Allocating sustainability oversight in committee charters and governance documents, setting the cadence of board reporting, and building the record that shows directors discharged their oversight duties.
03
Greenwashing & Claims Review
Reviewing marketing, labels, and investor messaging against advertising and securities standards, and documenting the basis for each claim so the public narrative and the internal record tell the same story.
04
Supply-Chain & Human-Rights Diligence
Building diligence programs for forced-labor, environmental, and human-rights exposure across the supply chain, with contractual safeguards and the documentation that due-diligence regimes increasingly demand.
05
Sustainable Finance Structuring
Structuring sustainability-linked loans, green bonds, and transition financing so the targets and covenants are measurable and defensible, with tax and capital-markets counsel brought in where the instrument requires it.
06
ESG Diligence in Transactions
Building environmental, social, and governance diligence into M&A and financing so supply-chain, climate, and labor liabilities surface before signing, while they can still be priced, allocated, or addressed.
What you should know
The realities that shape a workable ESG program.
01
The claim creates the obligation
Since April 2025 the UK Competition and Markets Authority can fine a business up to 10 percent of its worldwide turnover for a misleading consumer claim without first going to court, and its Green Claims Code sets out what "recyclable" or "sustainable" must be able to show. A press-release commitment is tested against that code, not against intentions.
02
The regimes do not agree
The EU's reporting directive runs on double materiality: a company reports its effect on the climate as well as the climate's effect on its finances. The ISSB standards that the UK and a growing list of jurisdictions are adopting use financial materiality alone. A group under both writes two accounts of the same facts, and investors read them side by side.
03
Greenwashing is a legal exposure
Substantiation has to exist before the claim is made, not be assembled after a challenge; the FTC standard is competent and reliable scientific evidence, and a comparative claim must say what it is being compared with. The claims most often attacked now are net-zero targets with no interim plan and carbon-neutral labels resting on offsets of uncertain quality.
04
Oversight has to be documented
A large UK company's directors must publish a statement each year explaining how they had regard to the community and the environment, a duty written into the Companies Act. In Delaware the question is whether the board set up a reporting system for the risks it treats as mission-critical. In both places the charter, the minutes and the escalation path are the evidence.
05
Data quality is the foundation
The EU directive requires independent limited assurance over the sustainability report, and lenders and buyers increasingly ask for the same outside any mandate. Assurance over supply-chain emissions is only as good as the supplier data behind it, which makes the data clauses in supply contracts disclosure controls. An untraceable number does not get published.
06
ESG is now priced into deals
A sustainability-linked loan moves the margin a few basis points against agreed indicators, and the market principles require independent verification of each indicator every year, so a missed target left unreported is a misstatement to the lenders rather than a missed bonus. Buyers test the same indicators in diligence, and an unverified claim becomes a representation in the purchase agreement.
The arc of a mandate
How this work runs
From published promise to defensible record.
- Stage 01
Regime mapping
We inventory the company's structure, listings, and footprint against the disclosure and diligence regimes that attach to it, including the SEC, UK reporting, and the EU sustainability directives, and separate what is mandatory from what past statements and contracts have quietly made binding.
- Stage 02
Gap-to-record audit
Every public claim in reports, labels, investor decks, and supplier codes is read against the internal record. Where the narrative outruns the data, we correct the claim or build the substantiation before anything ships.
- Stage 03
Governance hardwiring
Oversight moves from a slide deck into the charter. Committee mandates, board reporting cadence, escalation paths, and controls over sustainability data are written down so directors can show they discharged the duty rather than discussed it.
- Stage 04
Disclosure under scrutiny
The first filing cycle runs as if the regulator were already reading. Metrics are assured, cross-border reports are reconciled, and the protocols for comment letters and inquiries are written before the first one arrives, so the program holds up when a claim is challenged.
The moment a promise is published, it stops being marketing and starts being evidence.
Frequently asked
Common questions on ESG and sustainability counsel.
What is ESG and sustainability advisory?
ESG and sustainability advisory is legal counsel on the environmental, social, and governance obligations a company faces, covering disclosure and reporting, board oversight, supply-chain and human-rights diligence, climate-related risk, and the structuring of sustainable financing. It treats sustainability as a compliance and governance discipline, and it maps what a company says about its conduct to what the applicable rules and contracts require.
How does Hart David Carson LLP approach ESG matters?
Hart David Carson LLP advises on ESG as a governance and disclosure problem. We help boards and management work out which frameworks apply to their structure, sector, and footprint, build reporting that can withstand scrutiny, and align public statements with the underlying record. Where a matter turns on technical or jurisdiction-specific regulation, we coordinate with the appropriate technical adviser or locally admitted counsel.
Are ESG disclosures legally required?
For most US companies, no federal rule requires a sustainability report. A public company must still disclose material climate-related risks and proceedings under existing rules, and the SEC's 2024 climate rule was stayed before it took effect and is no longer defended by the Commission. The EU directive reaches groups with EU subsidiaries or substantial EU revenue, the UK requires climate-related financial disclosure from its largest companies, and several other jurisdictions have adopted the ISSB standards. A voluntary statement, once published, is held to the antifraud and advertising rules wherever it is read.
What is greenwashing risk and how do you manage it?
Greenwashing risk is the gap between a sustainability claim and the evidence behind it, and it is tested by regulators, by competitors and by class-action plaintiffs. We manage it with a claims register: every environmental or social statement in marketing, filings and investor materials, each with its substantiation, an owner and a review date. The FTC and the UK regulator both publish what "recyclable", "compostable" and "carbon neutral" must mean, and we hold each claim to the stricter reading, because the same label is read in both markets.
Does ESG affect financing and M&A?
Yes, through the documents. A sustainability-linked loan carries a reporting covenant and annual verification of its indicators; a bond issued under the EU Green Bond Standard must put at least 85 percent of its proceeds into taxonomy-aligned activities; a purchase agreement now carries ESG representations alongside the environmental ones. The buyer also inherits the target's published commitments and its supply-chain exposure, including goods that Customs can detain under the forced-labor presumption. We structure the instrument and build the diligence so the liabilities surface before signing.
Does Hart David Carson LLP handle ESG across borders?
Yes. The firm's principal office is in Chicago, its London and Dubai offices operate through partner firms, and a partner network of locally admitted counsel covers about 51 jurisdictions. The regimes diverge at the root: the EU reports on double materiality, the UK and other ISSB adopters on financial materiality, and the US through existing securities and advertising law. We reconcile them into one program and one set of claims, and we coordinate local counsel where a jurisdiction's law requires it.
