Travers Smith LLP

Heather Gagen

Co-heading Travers Smith LLP’s ESG and impact group, Heather Gagen is a key contact on novel and critical contentious climate and sustainability mandates. Building off her broad commercial litigation practice, Gagen brings leading experience on large-scale tort and parent company liability claims, reputationally significant disputes and investigations, and corporate risk management matters.

In a business-critical mandate, Gagen acted for agriculture corporate group Camellia in proceedings invoking parent company liability regarding alleged human rights abuses within its subsidiaries’ operations in Kenya and Malawi. The matter is crucial in establishing precedent for how companies should manage ESG risk throughout their value chains.

As part of the development and delivery team of the firm’s sustainability insights academy, Gagen supports the ESG training provided to the firm’s legal and business services teams. Gagen also extends her leadership within the legal community, participating in panel and podcast discussions on topics including ESG litigation.
