About the scheme

Chartered Architectural Technologists are at the forefront of innovations and helping develop the solutions we need to address the environmental and sustainability issues within the Built Environment sector and society as a whole.

Improving retrofit building and data-driven technologies, finding more sustainable resources, pushing for circular economy principles and policy – these are just some of the ways in which our worldwide community of Architectural Technologists are influencing change.

The professional award of Chartered Environmentalist (CEnv) recognises the specialist knowledge of CIAT's members whose work contributes to mitigating and solving environmental challenges.

CIAT is licensed by The Society for the Environment (SocEnv) to award the Chartered Environmentalist (CEnv) qualification. 

The CEnv qualification is granted to those who have demonstrated knowledge, proven experience, and a profound commitment to applying sustainable best practice within the area of sustainability and the environment.

Why become a CEnv?

The global Built Environment sector is seeing an increasing number of complex sustainability and environmental challenges, and as a result, there is growing demand for professionals who have the knowledge and experience to help solve these issues. The Chartered Environmentalist qualification, CEnv, is a demonstration of a Chartered Architectural Technologist's competence, professionalism, and dedication to providing solutions within this area. 

The Chartered Environmentalist qualification gives environmental practitioners:

  • a way of demonstrating their specialist competence within the sector,
  • recognition of their commitment to environmental best practice within their particular field of expertise,
  • professional registration with CIAT and the Society for the Environment,
  • recognition beyond their specific sector.

For employers, specifying CEnv status as a recruitment requirement gives them greater confidence in the environmental competence and professionalism of potential employees.

Eligibility criteria

To become a Chartered Environmentalist, an applicant must:

  • be a Chartered Architectural Technologist, MCIAT or FCIAT;
  • have a relevant Masters-level degree or equivalent level of knowledge;

If you do not have a Masters-level degree, then you need to demonstrate a level of knowledge and understanding equivalent to this, and have sufficient relevant experience to be able to meet the CEnv competences. If you are not sure whether you have sufficient knowledge and/or experience, please contact [email protected].

  • have sufficient, relevant and responsible practical experience to be able to demonstrate the competences;
  • demonstrate underpinning knowledge related to the environment and evidence of how it is applied in practice;
  • agree to comply with the Society for the Environment's Code of Professional Conduct and CPD requirements of CIAT.
