'Standing out for its analytical quality and timely deliverables' the sizeable - and for many, market leading - environmental team at Rodrigo demonstrates experience across the core regulatory, contentious and transactional segments of the practice. The group’s broad expertise encompasses water management, plastic use, protected natural area matters and environmental quality standards, to name a few key areas. A deep senior bench includes practice head and natural-resources expert Francisco Tong; Jenny Caldas, who advises on an array of environmental matters including audits and the implementation of relevant management systems; and Diego Pachas, who focuses on permitting, licensing and regulatory matters; along with environmental and mining law specialists Francisco Barrios and Mariana Delgado, the latter having been promoted to the partnership in January 2025. At counsel level, Úrsula Zavala is noted for her involvement in environmental litigation matters, as well as her expertise in regulatory compliance.
