B&W Derecho y Sustentabilidad

Former Creel, García-Cuéllar, Aiza y Enríquez, S.C. senior associate Mariana Westendarp departed the firm in April 2025 to become a founding partner at environmental boutique B&W Derecho y Sustentabilidad along with Yanin Beltrán. Westendarp can call on some 15 years private practice experience across the full range of environmental matters from transactional and day-to-day operational issues to remedial work across multiple industries and in relation to water and wastewater, environmental impact and risk, emissions, hazardous waste, climate change, carbon markets and coastal ecosystems, among other matters. Beltrán, in turn, has over a decade’s experience in the public sector, as both a legal analyst and as a subdirector for the investigation of environmental incident reports (part of the Environmental Prosecutor’s office) in Mexico City.
