Specialised in environmental conflicts and litigation, Estudio Gabriel Macchiavello’s deep bench of expertise is made up of 14 lawyers and 5 paralegals dedicated to environmental counselling and litigation. The practice draws from this strength to represent companies in lawsuits and administrative procedures related to collective damages, mass toxic torts, environmental damages, remediation and recovery of damages, as well as providing international and domestic corporations with advice on technical environmental standards and regulations. The firm also adds broad multidisciplinary expertise to its focused environmental work, namely transactional, compliance, permitting, legal audits and insurance. Leading the team are experienced environmental law practitioners Hugo Bunge Guerrico, Pedro Zambrano, Juliana Salvucci, Belén Counduros and Ramon Santamarina. Other key names in the practice include the recently promoted partners Florencia Borsani, who focuses on environmental, regulatory, health and hygiene advice; and environmental litigation expert Andrea Karina Gonda.

As a boutique specialised in environmental law, Venditti Hierro Quinteros knows the field and can provide comprehensive advice that covers regulatory, judicial and transactional matters. The firm’s broad expertise in the area includes the assessment of environmental liability, representation before administrative agencies, advice on contractual environmental issues and environmental compliance audits and due diligences. In addition to this the practice handles a range of environmental damage claims and defence in cases of civil liability (toxic tort actions) and associated criminal liability. Environmental and regulatory expert María Magdalena Venditti co-founded the firm with fellow team leads Mariana Hierro, whose strengths include environmental, industrial and oil-and-gas matters; María Carolina Quinteros, who focuses on natural resources and environmental law issues; and Lucía Sesto, whose practice is centred on environmental standards and administrative sanctioning procedures. The firm has also been growing at associate level with the February 2022 hires of semi-senior Florencia Nocera from Buenos Aires’ environmental regulator APRA, and junior Andres Di Maio from Franco Abogados.

Active in general environmental consultancy, compliance and due diligence, Brons & Salas’ primary focus is advising on the environmental law aspects of corporate transactions, which the team combines with strong regulatory and legislative practices. The multidisciplinary expertise in the team covers the key, inter-related sectors of mining, renewable energy, nuclear energy and oil and gas. Guillermo Malm Green  is practice head and is best known for corporate litigation arising from environmental issues and advising multinational companies and individuals on the environmental facets of M&A transactions. Specialist associate support is provided by senior Maria Agostina Mandrini  who has some 14 years in the sector and focuses on environmental litigation, compliance and audits, and remediation matters.

Working closely with its public law, dispute resolution, M&A, energy, mining and infrastructure practices, Baker McKenzie’s multidisciplinary team can advise across the spectrum of environmental issues. Santiago Maqueda is the go-to name in the area and his team is particularly strong on environmental compliance, class action litigation arising from environmental harm, environmental authority proceedings, and advising on national and global regulatory trends. The latter point includes complex issues around producers’ extended responsibility, global warming regulations, carbon credits and the disposal of soon-to-be-banned substances.

A small but longstanding player in the sector, environmental and safety-regulation boutique Franco Abogados has strength across a comprehensive range of consultancy issues, audits, administrative defence, litigation and training programmes. The team is particularly respected for complex contentious work, with extensive experience in reparatory and criminal actions. Founding partner Horacio Franco  is a veteran practitioner with a 25-year plus trajectory in the sector; well regarded, he advises on the full range of contentious and non-contentious matters. A similarly experienced practitioner, Eugenia Bec  provides additional partner-level capacity and input. The small team was strengthened with the hire of mid-level associate Natalia Mollard  from Abeledo Gottheil Abogados in early 2021.
