Firms To Watch: Environment

The September 2022 arrival of experienced senior associate Georgina Gutíerrez (from Sainz Abogados) as practice head has given a timely boost to Cacheaux, Cavazos & Newton‘s environmental and ESG capabilities; based in Mexico City, she oversees a four-strong team that undertakes the full range of  relevant matters (including audits, compliance and the appeal of administrative rulings, along with the environmental aspect of transactional matters), and has been active of late with mandates including industrial site closures and potential liabilities (civil, administrative and criminal) regarding water resources and non-hazardous waste.
The February-2023 hire of Carlos Del Razo (‘an exceptional lawyer’, with ‘great experience in the sector’, and whose ‘insight and advice is very practical’) from specialist boutique Carvajal Machado Abogados and who arrives as practice head at ECIJA’s Mexico office, signals the firm as one-to-watch in the environmental law sector; the four-strong team has been active in due diligence matters and representations before relevant authorities (such as SEMARNAT and CONAGUA), with notable mandates including assisting a mining operation in Chihuahua with the amendments of its existing environmental impact authorisations.
Leveraging the strength of its energy and renewables practice and clientele, Holland & Knight LLP is building out its environmental and ESG capabilities under the dual leadership of Rodolfo Rueda Ballesteros, who leads the Mexico office Regulatory and Governmental Affairs practice and energy partner Carlos Ochoa; recent matters – primarily relating to the energy and infrastructure sectors – include the regularisation and extension of environmental impact authorisations and water concessions, environmental restructuring and due diligence, and legal, environmental and regulatory advisory.
With over 20 years’ experience, Luis Esparza is the key contact at LAER Abogados, S.C., a specialist boutique founded in 2018 that handles water law, environmental management and impact reports; environmental emissions, waste and land use; risk evaluation and viability studies; transactional environmental advice and due diligence; Ecuator Principles compliance, and the environmental aspects of energy projects, among other matters.
Founded back in 2011, 10-strong firm Lammoglia Abogados is an up-and-coming environmental boutique that handles the full range of environmental matters along with associated -primarily administrative- litigation, and is particularly active across the renewable energy, real estate and hospitality sectors; founding partner Franco Lammoglia is the primary point of contact, with key support coming from senior associate María Fernanda Garibay.
Formerly the practice coordinator of Baker McKenzie Abogados, S.C. environmental practice Mario Facio Salazar is now the environmental partner at cloud-based start up law+dgtl; with over 20 years specialising in the sector, his practice covers environmental, climate change and regulatory matters, along with real estate, and he has extensive experience acting before PROFEPA, CONAGUA and the Federal Agency for Safety and Environmental Protection in the hydrocarbons industry.
Nader, Hayaux y Goebel, SC‘s sustainable transition working group is not an environmental practice as traditionally conceived but is instead focused on advice and consultancy (for clients such as BBVA, HSBC and Grupo FRISA) related to the World Economic Forum’s Climate Governance Initiative (CGI), along with associated matters such as green finance, sustainable development goals, the issuance of BioCredits and bonds, and environmentally conscious governance strategies, among others; name partner Yves Hayaux-du-Tilly is the key contact and has led the firm’s efforts to establish not-for-profit entity Chapter Zero Mexico – effectively the local chapter of the CGI. Since publication, the firm has announced the hire of Marcela Ánimas as a partner – effective as of January 2024; arriving from her own boutique, Ánimas’ incorporation should radically broaden the practice’s capabilities across the environmental impact, risk and compliance segments, along with water law.
Former senior counsel and head of the environmental law and regulation team at Holland & Knight LLP, Héctor Velasco Perroni (who ‘balances complicated substantive legal advice with practical considerations very well’) spun-off his practice to form micro-boutique Perroni & Associates (P&A) in mid-2020; the firm handles environmental and regulatory compliance, indigenous community matters, water rights, Equator Principles-related issues, environmental impact and risk assessments, forestry law and hazardous materials – the latter being a niche where it has particular expertise.  
With over 20 years’ environmental sector experience, Marcela Ánimas -formerly a counsel at Mijares, Angoitia, Cortés y Fuentes S.C.– leads the practice at Woods Ánimas, a boutique firm with a tight focus on water law and a broad range of environmental matters including: climate change; environmental impact and risk; waste, atmospheric emissions; wildlife; coastal ecosystems; marine environments; forest land use modifications; and administrative responsibility related to environmental issues along with associated compliance. Since publication, Ánimas has left the firm - effective as of December 2023.

Creel, García-Cuéllar, Aiza y Enríquez, S.C.

Best known for providing assistance on the environmental aspects of M&A, financings and -particularly- real estate related matters, the 10-strong team at market mainstay Creel, García-Cuéllar, Aiza y Enríquez, S.C. provides the full spectrum of environmental, sustainability and climate change-related advisory and associated administrative and constitutional litigation. A capable and experienced senior team includes departmental head Carlos de Icaza (who divides his time between real estate and environmental practices), and a deep second-line consisting of Alejandro Castelló (environmental law and real estate), Jessica Villaverde (environmental impact assessments, water law, hazardous wastes and site remediation), and Mariana Westendarp (environmental litigation, impact assessments, risk and remediation, among other matters) – all three of whom were raised to counsel in August 2022; each can draw on over 15 years’ experience in environmental matters. In the absence of projects-related mandates the team has primarily been active in transaction-related environmental matters, advising Arcosa on the restructuring and sale of its Mexican vessels-manufacturing business; ABC Group on the acquisition of automotive component manufacturer dlhBowles; and Steel Dynamics in connection with ferrous and non-ferrous scrap recycler Roca Acero, among other matters. Other significant mandates include counselling Celanese on all environmental legal requirements related to the definitive closure and dismantling of a gas pipeline in the state of Jalisco, including acting before Mexico’s Agencia de Seguridad, Energía y Ambiente (ASEA) to obtain all relevant authorisations. The team has also been increasingly active in administrative environmental litigation, and in water-related matters -particularly in the State of Nuevo León- following 2022’s water-scarcity crisis.

Galicia Abogados S.C.

Drawing on the support of a strong litigation and arbitration practice group for judicial and/or administrative representation as necessary, Galicia Abogados S.C.’s full-spectrum environmental practice has considerable experience in transactional work and associated due diligence, regulatory matters, compliance, litigation and ESG issues, and acts primarily for clients drawn from the energy, real estate and regulated industries (including, ports, roads, water projects and pharma). The nine-strong practice group is co-led by Mariana Herrero, who has in-depth knowledge of the full range of environmental legal matters and who is accustomed to multidisciplinary approaches to such issues; and Carlos Escoto -who was raised to the partnership back in early 2021- and brings sophisticated regulatory and sustainability experience to the group, particularly in relation to the development of infrastructure, renewable energies, oil & gas, mining, manufacturing and tourism industry projects. At associate level, key support is provided by seniors Lucía Manzo and Lourdes Lozano – who both primarily attend to the regulatory and environmental aspects of infrastructure and energy projects; and associates Verónica Palacios (a former director of hydrocarbons regulation at the Comisión Reguladora de Energía), and Guillermo Garza (who rejoined the firm in June 2022 after four years at Vera y Asociados). Recent matters include involvement in the filing of constitutional amparos concerning various government reforms, advisory concerning carbon credit generation projects, and matters arising from the financing of a water treatment and desalination plant.

Practice head(s):

Mariana Herrero; Carlos Escoto


Galicia Abogados has a robust team for environmental legal issues, giving practical and timely advice. For environmental legal matters that result in administrative litigation, they combine their practice with their litigation team.

From the environmental legal team I’d highlight Carlos Escoto, Guillermo Garza and Gabriela Espir: they have provided detailed and practical advice for specific issues. From the litigation team, Sofía Jurado and Gilda Velásquez, have linked environmental legal issues with a defense at the administrative level.

I consider that the benefit of the Galicia Abogados’ team is its specialisation in environmental issues, knowledge of the regulations and good relations in general with the authorities. This allows quick and direct responses to problems.

Foremost is the excellent quality of the team’s professionals. I find it very useful that those in the environmental field all have different specialties, that is, each one within their specialty manages a specific branch such as circular economy, wildlife, etc.

Carvajal Machado Abogados

A ‘go-to‘ name in the sector, Carvajal Machado Abogados handles the full array of environmental law matters, including on-site inspections, environmental impact assessments, waste management, water use and discharge, air emissions, and regulations concerning wildlife and natural protected areas. Indeed, recent mandates include the successful 12-year renewal of Compañía Minera Cuzcatlán’s environmental impact authorisation, advising ENI Mexico with regard to HSE regulation and compliance (including environmental insurance, accident reports and root-cause investigations), and assisting various community and neighbourhood groups with the blocking of illegal real estate developments. Nevertheless, it is perhaps the combination of the firm’s environmental practice with its robust administrative litigation capability that really sets the practice apart. Practice head Gustavo Carvajal handles both administrative and environmental law matters, while fellow name partner Juan Pedro Machado is a dedicated administrative law specialist who also frequently participates in contentious environmental matters. Carvajal is closely supported by dedicated environmental practitioner and senior associate Jorge Gómez DeSilva, who focuses on environmental impact assessments, regulatory compliance due diligence, forest land use, natural protected areas, ecological and urban programs and water concession matters. However, former partner Carlos Del Razo left the firm in February 2023.

González Calvillo

The nine-strong environmental practice at Gonzalez Calvillo handles the full array of environmental matters, ranging from contract review and environmental due diligence, through risk mitigation and preventative measures, to project development related matters and administrative litigation. The group also houses expertise regarding clean development mechanisms, climate change policy and ESG. Recent matters include assisting Smurfit Cartón y Papel de México on all issues related to its water usage and associated concession titles; undertaking due diligence of the environmental and urban development matters related to a hotel development in Quintana Roo; and aiding Triumvirate Environmental obtain various environmental permits, including hazardous waste import authorisations, civil protection approvals and various modifications to the company’s waste transportation permits.

Further depth is provided by counsel Julia González, who devises strategies as regards regulatory, litigious and risk prevention, as well as handling social impact matters; and senior associate Georgina Zavala, a water law specialist. Former senior Paulina Poo Romero moved in house in February 2023.

Practice head(s):

Enrique Muñoz; Carlos Castilla; Paola Hernandez


The Gonzalez Calvillo team is very competitive compared with other Mexican firms; in personal terms, their consultancy has allowed us to improve greatly as a company in environmental terms – apart from the great communication, availability and impressive friendliness of the individuals who make up the team, i’d principally note the competency which they bring to bear. I’d particularly note Lic. Enrique Muñoz.

The area is very complete. They have very good technical knowledge and are always willing to solve and explain. The team is highly responsive and reliable in every way.

They maintain a sense of urgency and ensure issues are followed up.

Ibarra, del Paso y Gallego

While the six-strong team at mid-sized firm Ibarra, del Paso y Gallego is smaller than some of its competitors, it benefits not just from being a stand alone practice but also one of the founding pillars of the firm, thereby ensuring a degree of autonomy and a breadth of offering not necessarily available at even the largest practices. The group covers the gamut of environmental matters and has built a sturdy reputation for its capabilities in all key segments: advisory and consulting – particularly in relation to transactions (contingencies, risk & due diligence); administrative procedures and litigation (before entities such as SEMARNAT, PROFEPA or CONAGUA); and regulatory matters – concerning environmental impact, water, wastewater discharges, change of forestry land use, natural protected areas, ecological zoning, hazardous and non-hazardous waste (including soil contamination and remediation), and air emissions – in relation to the development of all types of projects. The department is led by transactional and regulatory environmental specialist Adrián Del Paso, with close support from senior associate Mauricio Sandoval, who primarily undertakes administrative litigation. August-2022 associate-hire, Miguel Angel Cancino – who arrived from QV Gestión Ambiental – is also noted. In addition to its direct clients, the practice handles work outsourced by various law firms –particularly those in the mid-market– that do not possess their own environmental capability, picking up a healthy flow and range of mandates that ensure its exposure to the broadest range of environmental issues. Recent matters include permitting regularization in the hospitality sector; the environmental and water law aspects of a potential land acquisition for the purposes of a greenfield industrial development; transactional and internal (preventative) legal environmental due diligence processes; the defence of administrative proceedings brought by state environmental prosecutors on grounds of the alleged lack of relevant environmental licenses; the assessment and investigation of alleged/potential environmental contingencies; and day-to-day advisory and consultations. Since publication, del Paso and Sandoval have left the firm- effective as of March 2024.


Adrian del Paso is a true gentleman and knows his way around the law, with governmental agencies and technical experts. His approach and demeanor permit discussing swiftly both highly technical environmental issues and the law; a clear explanation between both and how these apply to the particular circumstances.

It is a proactive firm. The response time is very quick. It’s fees are very reasonable and the lawyers posssess great experience and knowledge as regards ambiental matters. They are very practical.

Adrián del Paso. Very professional and expert in this practice.

Adrian del Paso and Mauricio Sandoval know the law, communicate the current environment with governmental agencies and convey their analysis and recommendations in simple English but yet considering the technical aspects of each case.

Pontones & Ledesma

With over 15 years in the market, specialist environmental boutique Pontones & Ledesma has a well-established track record in the sector and 'extensive knowledge of all the factors that can influence an issue with environmental overtones - from consulting to litigation, mitigation measures and legal enforcement'. The ten-strong team handles the gamut of relevant matters (advisory, contentious and strategic), and has been particularly active of late advising on environmental compliance (particularly regarding wastewater and hazardous waste), environmental impact assessments and audits - notably in relation to the real estate, manufacturing and retail sectors. The practice is led by founding partners Luigi Pontones and Arturo Ledesma whose combined expertise covers the full range of specialist environmental matters, from the design of legal strategies concerning environmental matters (particularly regarding audits and litigation), via the obtaining of authorisations and permits from entities including SEMARNAT, ASEA and CONAGUA, through to advisory on the gamut of relevant issues (such as biodiversity, environmental impact and risk, atmospheric emissions, noise, urban solid waste, hazardous pollution and soil remediation), and relevant litigious matters including administrative, amparo and nullity proceedings and popular complaints. The pair can draw on key support from a core group of experienced senior associates consisting of Valeria Bustamante, Pablo Martínez Santuario (who each have over a decade at the firm) and Irvin Mallen. Former associate Michelle Ocampo left the firm in November 2022.

Practice head(s):

Luigi Pontones; Arturo Ledesma

They know the strategies to adopt, they are clear in their steps and extremely detailed in their reports.

Vera y Asociados

Long a nursery for environmental legal talent, Vera y Asociados is a specialist boutique that undertakes the full range of environmental matters but that also has a strong dedication to strategy origination and complex litigation. Firm senior partner and practice head Luis Vera has a 30-year plus trajectory in the sector; a some time director of the Agencia de Seguridad, Energía y Ambiente (ASEA), he is undoubtedly one of the practice area’s founding fathers and frequently consults on draft legislation. He is flanked by younger partners: Alejandro Aldana (who focuses on manufacturing, water law, environmental impact matters, environmental issues associated with traditional and renewable energy projects, and environmental, administrative and tax litigation); María Cristina Hernández C (environmental matters concerning tourism, mining, infrastructure and energy projects; water law, environmental impact assessment, forestry land use change, hazardous waste management and environmental audits, along with social impact assessment and indigenous consultation); and administrative and constitutional litigation specialist Genaro García, whose background also includes relevant public sector experience at both PROFEPA and ASEA. Key associates include Israel Vera (no relation), who focuses on federal zoning issues and can draw on some seven years public sector experience at SEMARNAT and ASEA; and contentious specialist Miguel Cardozo (particularly as regards water litigation), a July-2022 hire from Morales Banuet y Asociados. Recent matters include environmental impact and risk reports (among other matters), for the likes of New Fortress Energy, Mexico Pacific, Igasamex Neomexicana and Iberdrola; advising tourist developments including Marina Puerto Escondido Loreto, Misión XXI and Puerta Cortés on environmental compliance; and handling residues regularisation on behalf of Polimeros Especiales and Arkema. The team has also undertaken representations before administrative entities including CENACE, CFE, SEMARNAT and PROFEPA, among others.

Von Wobeser y Sierra, SC

Benefitting from the firm’s increasingly defined market position as a full service firm oriented primarily towards long term relations with its clients, the environmental team at Von Wobeser y Sierra, SC benefits from both a steady stream of transactional matters and the ongoing matters generated by the firm’s strong industrial and manufacturing client base. While this constitutes some 60% of the team’s current activity, the remainder is made up of administrative (environmental) litigation – particularly, of late, concerning water resources, concessions and supply. The 11-strong team is co-led by Edmond Grieger, who has some 20 years’ experience in the sector, including both advisory and compliance concerning complex M&A and major project and infrastructure developments, as well as environmental and administrative litigation; and energy and projects specialist Ariel Garfio, whose expertise takes in contractual, environmental, regulatory, social impact, rights of way and agrarian matters. While the practice has seen some changes at the more junior level, key support comes from mid-level associate Roberto Flores, whose practice is centred on environmental law, energy and natural resources and real estate. Headline mandates include ongoing assistance to Ivenergy regarding all the environmental and social authorisations and licensing concerning its more than 20 renewable and co-generation plants across the country and in particular advice concerning all environmental aspects of the company’s Parque Eólico de Fenicias project, currently at the EPC stage. Other matters include advising Blanmin on the environmental and administrative matters required to regularize two mining concession titles in Campeche; and Nissan on compliance related matters concerning its water concession obligations before CONAGUA for the operation of its facilities in Aguascalientes and Morelos.

Anaya Díaz Ibáñez

The January 2023 arrival of Héctor A Garza at Anaya Díaz Ibáñez (after some seven years at Ritch, Mueller y Nicolau, S.C.), along with senior associate Jose Enrique Cruz -an administrative and constitutional litigation specialist- has allowed the firm to add an environment, indigenous peoples, and urbanistic law practice to its already diverse offering. The seven strong team offers an integrated environmental and social impact practice, notably differentiated by its know-how in indigenous peoples’ law – indeed, the team recently handled Mexico’s first-ever first Human Rights Impact Assessment (HRIA), handling both social (concerning indigenous communities) and environmental aspects. It is also experienced in climate change matters, particularly in relation to energy (notably renewables), projects and real estate. In another ‘first’, the practice is also involved in the design and development of a major blue-carbon project in Mexico to date, which seeks to restore mangroves in the State of Yucatán. Current chairman of the Environmental Commission of Mexico’s International Chamber of Commerce, and in addition to his niche expertise in law regarding indigenous peoples, Garza’s practice covers the development and financing of projects, including proceedings before federal, state and municipal authorities; environmental impact assessments and audits; free, prior and informed consultation (FPIC), matters pertaining to the Equator Principles and IFC Performance Standards; health law, climate change, soil contamination and remediation, the circular economy and agrarian legislation. Currently involved in a novel case of cultural appropriation, he also advises on the design and implementation of culturally relevant social investment and management plans. Other recent mandates include advising GTM and Croda on their Mexican ventures – involving the negotiation of real estate agreements, design and submission of environmental impact and prefeasibility assessment studies, and general regulatory advice, among other issues.

Baker McKenzie Abogados, S.C.

The small, four-strong team at Baker McKenzie Abogados, S.C. handles the full range of environmental and climate change law matters, from regulatory compliance, clean-ups, audits, and corporate policies and management systems, to contentious administrative proceedings, environmental litigation, and health and safety issues, particularly as regards the real estate, mining and infrastructure, pharmaceuticals and healthcare, automotive, hotels and hospitality, food, chemical, petroleum and manufacturing industries. Chair of the firm’s environmental and climate law practice in Mexico, senior counsel Frederico Ruanova-Guinea heads the practice and brings some 35 years’ experience to bear. Key support comes from finance-oriented senior associate Alejandra Muriel-Vizcaino; however, the departure of specialist senior associate and practice coordinator Mario Facio Salazar in September 2022 had undoubtedly impacted the practice. Recent matters include environmental surveys and reporting in relation to industrial facilities, issues pertaining to battery waste, and advising clients on seeking amendments to the ban on single-use plastics enacted in Mexico City.

Greenberg Traurig, S.C.

The five-strong practice group at Greenberg Traurig, S.C.‘s Mexico office has benefitted from the firm’s international standing, as well as its local transactional prowess, to successfully replace the shortfall in projects work under the current administration with a strong pipeline of transactional engagements. A wave of sales by Mexican companies in the second half of 2021 has segued into a scenario where near-shoring has become the predominant transactional driver, with the firm proving adept at securing relevant mandates. The team has also gained traction in the mining section where activity has included M&A, restructuring and arbitration-related matters, with the May 2023 mining reform only serving to further increase engagements in the industry.

Grepe, Lavin & Zavaleta, SC

The 11-strong team at Grepe, Lavin & Zavaleta, SC is co-led by Pedro Morales (a former counsel and head of the environmental practice group at White & Case S.C. and whose past experience also includes time at the Ministry of Environment and Natural Resources – SEMARNAT); and administrative litigator David Perales, whose practice reaches into environmental and regulatory matters and who also has experience in the real estate sector. Indeed, their respective strengths are very much complimentary, ensuring the team has a full contentious and non-contentious offering. Moreover, the pair can call on tax partner Juan Ignacio López Domínguez with regard to environmental tax matters (especially at the State-level, where such levies are a growing issue), as well as for additional administrative-litigation support; and at associate level, on corporate associate Luis Ayala who is active on environmental matters. Recent headline work includes advising Californian-entity Climate Action Reserve (CAR), on the drafting of its new Forest Protocol for the development of carbon-related forest conservation projects (subsequently assisting it with the drafting and review of documentation pertaining to various agreements with forest land owners for the development of such projects); and counselled civil association BlueMX on obtaining carbon rights from communities and regarding carbon-rights transfer agreements in relation to mangroves in Mexico. Other matters have seen the team particularly active in relation to near-shoring and associated permitting and licensing issues, and it also picks up considerable work from a range of mid-to-large law firms that do not have their own environmental practice – particularly concerning transactional due diligence issues.

Hogan Lovells

Following the January 2023 departure of former practice head Brenda Rogel, the Mexico office of full service international firm Hogan Lovells‘ hired experienced practitioner Mauricio Llamas from Jones Day in April 2023, bringing senior associate Mauricio Villegas with him. Llamas – who originally opened his own specialist environmental boutique firm back in 2008 –  has over 20 years dedicated to the sector and also has broader experience that reaches into government regulation and environmental health and safety (EH&S) matters. This latter area is also an area of specialism for Villegas who advises domestic and international clients on a wide array of EH&S compliance matters and M&A environmental auditing procedures. The team is rounded out by Sofia de Llano and Santiago Contró (mid- and junior-level associates, respectively) who also arrived with Llamas; and a pair of January 2023 hires that further the practice group’s capabilities in the ESG space: practice director Pablo Necoechea, and ESG-focused associate, Mariana Ávila Martínez. While it remains early to see how the practice will bed in at the firm initial signs are positive with the group handling a more or less balanced workload split between environmental consultancy, environmental auditing and environmental litigation for clients in the hydrocarbons, metallurgy and mining, and industrial recycling sectors, among others. Recent mandates include comprehensive advice for the development of a one-of-a kind, waste-to-energy and recycling facility in the north of Mexico.

Recognised as a ‘genuine specialist‘ by peers (and ‘a thoughtful and confident advisor‘ by clients), Torres’ practice nevertheless has breadth – the regulatory, environmental, health, energy and administrative sectors all being areas in which he has considerable experience. He can draw on additional, associate-level support in the form of Andrés Lieja, a tax specialist who has strong administrative litigation experience, including on environmental matters.

Mijares, Angoitia, Cortés y Fuentes S.C.

The environmental practice at Mijares, Angoitia, Cortés y Fuentes S.C. is co-led by of counsel Gabriel Calvillo and senior associate Paula Pérez, and constitutes one of the pillars of the firm’s new ESG practice, launched in August 2022. The five strong team handles the gamut of relevant matters, particularly environmental M&A due diligence, compliance, risk and damage prevention, and liability matters; it is perhaps best known, however, for its capabilities in relation to administrative and criminal environmental litigation. Recent headline work included advising Actis on the Mexican-law aspects of the sale of a portfolio of renewable energy projects to GIP Helios; with other matters including extensive environmental due diligence and environmental regulatory compliance, particularly in relation to the water segment. Nevertheless, like all in the sector, the practice has felt the effect of the considerable downturn in complex project-related mandates; indeed, Calvillo has to a certain degree re-oriented his practice so as to focus more on corporate criminal liability and criminal compliance, and was appointed the firm’s criminal compliance officer in July 2022. Key associate support comes from Paulina Martínez, whose experience includes two years as a director at the Procuraduria Federal de Proteccion al Ambiente; and the ‘impressiveAisha Calderón, whose practice includes both environmental and energy aspects – particularly in relation to the electricity sector.
