Claire counsels companies in a range of sectors, including information technology, data centers, manufacturing, energy, chemicals, textiles, and aviation, on assessing and managing legal and commercial risks arising from climate, human rights, and environmental due diligence and reporting requirements.

She advises on supplier risk assessments, supply-chain mapping, the design of responsible sourcing programs, and the use of AI tools in regulatory due diligence, helping clients mitigate regulatory, enforcement, and litigation risk. Her work includes counseling on frameworks such as the Canadian Supply Chain Act, German Supply Chain Act, Norwegian Transparency Act, EU Corporate Sustainability Reporting Directive (CSRD) and Corporate Sustainability Due Diligence Directive (CSDDD), Uyghur Forced Labor Prevention Act, modern slavery reporting regimes, climate-related financial risk and greenhouse gas (GHG) disclosures, and green marketing and consumer protection requirements.

Claire also advises on sustainability-related transactions and commercial arrangements, including negotiating responsible sourcing and ESG data-sharing provisions, structuring carbon-reduction and carbon-market strategies, counseling on carbon credit methodology, project development, and transactions, and accessing government incentives supporting the green transition.

Claire’s sustainability practice is grounded in her background in international trade and environmental law. She has advised sovereign and private clients on matters arising under bilateral and multilateral trade and investment agreements, including World Trade Organization (WTO) disputes, and on issues at the intersection of trade, investment, and climate, such as emissions trading schemes, carbon border adjustment measures, and green energy subsidies. She leverages that cross-border perspective to help companies anticipate regulatory developments, align legal strategy with business priorities, and manage global compliance obligations.
