Meg Ferreira Cirilo has been working with environmental and energy law since the beginning of her career, which provided her with in-depth training and comprehensive knowledge to tackle all kinds of legal and policy issues. Her legal practice includes advising clients with respect to compliance with environmental regulations, permitting requirements, environmental due diligence, and liability management. She holds an LLB degree from the Universidade do Estado do Rio de Janeiro, an MBA in Sustainable Business Management from Universidade Federal Fluminense, and an LLM degree in Environmental Law with a Specialization in Energy and Climate Change Law from the Elizabeth Haub School of Law at Pace University (United States).

During her LLM programme, she became a student researcher at the Pace Energy and Climate Center, dealing with current challenges relating to energy and climate change law and policy, such as the integration of distributed energy resources into the electric grid, and provision of access to clean energy opportunities to low- and moderate-income customers. She also worked as an adviser to the Permanent Mission of Costa Rica to the United Nations, providing support to initiatives on sustainable development, particularly the implementation of the Sustainable Development Goals.
