Cormac Cullinan

Cormac Cullinan is a director of Cullinan & Associates, a specialist environmental and green-business law firm based in Cape Town, South Africa. A pioneer of environmental law and governance with decades of international experience, he leads a practice devoted to protecting the environment and advising the businesses and organisations that operate within it. That dedicated focus has earned the firm recognition as Environmental Law Firm of the Year in South Africa at the Corporate INTL Global Awards 2026.

A pioneering environmental law practice

Cullinan & Associates has its origins in the late 1990s. While living in London in the 1990s, Cormac Cullinan obtained a master's degree in environmental law from the University of London and established an environmental governance consultancy, EnAct International, that worked in more than forty countries. Together with Terry Winstanley, who moved to Cape Town in 1997 to establish the firm, he set out to build a boutique environmental law practice in South Africa. Cullinan returned from London to Cape Town in 1999 and became a director of the partnership, which was later incorporated and, following the departure of its other founders, renamed Cullinan & Associates. The firm has thus been dedicated to environmental and green-business law from its very beginning.

Environmental law and governance expertise

As the firm describes him, few lawyers can rival the depth and breadth of environmental law and governance expertise that Cormac Cullinan has acquired through working in more than twenty countries over three decades. Environmental law is a wide-ranging field that touches on regulation, compliance, natural-resource use, conservation and the growing body of law concerned with sustainability and climate. It requires both technical legal knowledge and an understanding of the ecological and policy context in which decisions are made. A firm that concentrates exclusively on this area, alongside green-business work, offers clients a genuinely specialist alternative to a general commercial practice.

Environmental and green-business law practices commonly assist clients with matters such as:

• Environmental regulatory compliance and authorisations
• Advice on natural-resource, conservation and land-use questions
• Environmental governance and sustainability strategy
• Environmental aspects of projects and transactions
• Environmental disputes and enforcement

Purpose-driven counsel from Cape Town

What sets Cullinan & Associates apart is the sense of purpose behind its work. Built by lawyers who set out to create a dedicated environmental practice, the firm brings conviction as well as expertise to the protection of the environment, and it is supported by a team of directors and attorneys who share that commitment. For businesses, organisations and individuals dealing with environmental issues in South Africa, this focus means their matters are handled by lawyers immersed in the field rather than treating it as a sideline. Cormac Cullinan's standing, including work that has taken him across many countries and into the development of environmental governance, anchors the firm's reputation.

Recognition for a purpose-driven practice

Recognition as a leading environmental law firm reflects both the rising importance of environmental and sustainability issues and the standing of a practice built specifically to address them. Environmental law is a wide-ranging and evolving field, spanning regulation, natural-resource use, conservation and the growing body of law concerned with sustainability and climate, and it calls for advisers who combine technical knowledge with genuine understanding of the ecological and policy context. An award of this kind acknowledges a firm's dedicated focus and the depth of experience behind it. For a practice established by lawyers who set out to create a boutique environmental firm, it also reflects the conviction and purpose that clients value, and the confidence that comes from working with a team immersed in this field rather than treating it as an adjunct to general commercial work.

For clients facing environmental legal and governance challenges in South Africa, Cormac Cullinan and Cullinan & Associates offer specialist, purpose-driven counsel from Cape Town. The firm's recognition as Environmental Law Firm of the Year in South Africa at the Corporate INTL Global Awards 2026 underlines its standing as a leading environmental law practice.
