Publicado el 30 ene 2026

The moves strengthen the firm’s regional positioning in legal advice related to environmental compliance, ESG and sustainable transition.
Marco Quesada has more than 10 years of experience in Environmental and Sustainability Law, with an outstanding track record in regulatory compliance, environmental audits, due diligence processes, environmental litigation and greenhouse gas management, both in Costa Rica and in other countries in Central America, the Caribbean and the United States.
Prior to joining ECIJA, he served as regional director of the environmental department at a Central American firm and as manager of sustainability and environmental law at Ernst & Young, where he led complex projects for companies in multiple sectors and industries.
He holds a law degree and a master's degree in environmental law from the Universidad de Costa Rica and has a solid technical background as a lead and internal auditor in ISO standards, as well as specialized certifications in carbon neutrality, greenhouse gas verification and GRI standards.
“Marco's incorporation responds to a clear strategic vision: to support our clients in the regulatory, environmental, and climate challenges that directly impact their business decisions today. Environmental law and sustainability are no longer ancillary areas. Today, they are central pillars of corporate management, access to financing, and corporate reputation,” said Mauricio París, managing partner of ECIJA Costa Rica.
The launch of the practice will allow ECIJA to offer specialized advice on environmental and regulatory compliance, ESG and corporate sustainability, environmental due diligence in M&A transactions, waste management, circular economy, climate change, carbon footprint, carbon neutrality and environmental litigation, integrating transversally with the areas of corporate, energy, infrastructure, TMT, compliance and dispute resolution.
For his part, Marco Quesada highlighted the focus of the new practice: "I am joining ECIJA with the aim of building a modern, rigorous environmental practice that is aligned with the international standards demanded today by investors, regulators, and markets. Costa Rica and the region are facing a profound transformation in environmental and climate matters, and the role of the lawyer is to become a strategic partner who helps organizations anticipate risks and generate value from sustainability”.
With this incorporation, ECIJA reaffirms its commitment to the growth of strategic practices linked to sustainability, regulatory innovation and comprehensive accompaniment to companies with operations in Costa Rica and Latin America.
