Environmental lawyers at Posse Herrera Ruiz strike the right note with clients for being ‘very professional and assertive in their recommendations’. Maintaining a multidisciplinary approach, the group demonstrates strong skill sets in environmental compliance, clean energy, decarbonisation and transactional support matters. Up-and-coming environmental law specialist and department co-head, Erika Serrano, made partner in May 2024 and is highlighted for her ’practical and strategic advice’; she recently advised ONGC Videsh (Colombia branch) on environmental matters related to modifying existing licences to increase hydrocarbon production in Colombia. Other key contacts include fellow co-head Alvaro José Rodríguez, whose environmental law practice is strongly informed by his formidable energy and natural resources expertise; and mid-level associate Sofía Ángel, who is a dedicated environmental practitioner. Junior associate Pablo Mejía left the firm in June 2025.
