At CIOB, we know that our members don’t just shape buildings, they shape communities, economies and the future. As a Chartered Member or Fellow, you’ve already proven your commitment to high standards, ethical practice and professionalism. Now, you have the opportunity to take that even further by becoming a Chartered Environmentalist (CEnv).

Why become a Chartered Environmentalist?

Becoming a Chartered Environmentalist is more than a professional title—it’s a statement. It tells the world that you put sustainability at the heart of your work, and that you’re actively contributing to a more responsible and resilient built environment.

Chartered Environmentalists are recognised for applying their knowledge and influence to protect and enhance the environment. Whether that’s through low-carbon design, sustainable materials, regenerative approaches, or leadership in environmental policy, CEnv status reflects real, measurable impact.

Climate challenge through the built environment

Construction is critical in tackling climate change and building a more sustainable world. Our industry is uniquely placed to lead this transformation, from reducing emissions and waste, to championing biodiversity and designing for long-term resilience.

And many of our members are already doing this. If you’re leading greener projects, mentoring others in best practice, or challenging the status quo, you’re exactly who CEnv was made for.

Recognition that reflects your values

CEnv status is awarded by the Society for the Environment, and CIOB is a licensed member body, meaning we can support our Chartered Members and Fellows in achieving this respected designation.

It gives formal recognition to something many of our members are already doing: leading with integrity, building responsibly and working toward a better future.

Highlighting impact over title

It’s important to note that being a Chartered Environmentalist isn’t solely about holding a sustainability-specific role. It’s about the impact of your work. For example, you can be a project manager implementing sustainable processes or initiatives, contributing significantly to environmental goals without needing the title of "sustainability manager."

Making a positive difference to our environment

If you’re passionate about driving change in your organisation or across the wider industry, CEnv gives you the platform to do even more. It’s an opportunity to:

• Be recognised as a sustainability leader
• Join a cross-industry network of like-minded professionals
• Influence how the built environment evolves
• Demonstrate your values and impact to clients, peers and future employers
