Jason Marett

Jason Marett is a partner in HFW’s trade finance group in Geneva and advises on trade and commodity finance transactions across global commodities markets. He works with commodity traders, producers, banks, funds and financial institutions on structured trade finance, borrowing base and prepayment structures, letters of credit, receivables financings, derivatives and other financings.

Jason has particular expertise in sustainable finance in the commodities sector. He advises on the structuring and documentation of sustainability-linked loans and green loans, the integration of ESG considerations into trade finance products, and the management of greenwashing and reputational risk. His work frequently involves supply-chain sustainability issues, and the adaptation of sustainable finance frameworks to the practical realities of commodity trading and trade finance structures.

He regularly advises on the application of voluntary market standards, including sustainability-linked and green loan principles and trade-finance-specific initiatives, and on how ESG-linked finance products interact with broader regulatory and compliance frameworks.

In addition to his client work, Jason is an active contributor to thought leadership in sustainable trade and commodity finance. He regularly publishes and speaks on sustainability-linked lending, green trade finance and greenwashing risk. He has also lectured on sustainable finance as part of postgraduate university programmes.

Jason is dual-qualified in New York and England & Wales and has practised at leading international law firms in London, Milan, Munich and Geneva.
