Architects Climate Action Network.jpg



ACAN is a network of individuals within architecture and related built environment professions taking action to address the twin crises of climate and ecological breakdown. 




We are in a state of climate and ecological emergency. There is a compelling body of scientific work indicating our present trajectory will lead to catastrophe if we do not make ambitious and radical changes as a matter of urgency.  


We also acknowledge that the construction industry and the existing built environment are major contributing factors to the crises and as such both require complete and rapid transformation. In the UK, the built environment as a whole is responsible for 42% of national emissions. The manner in which we produce, operate and renew our built environment continues to curtail biodiversity, pollute ecosystems and encourage unsustainable lifestyles. 


This state of emergency calls for a new kind of professionalism. We can no longer remain secluded within our personal and professional silos. Instead we are harnessing our collective agency; as citizens with a shared professional background and a common goal, mobilising to bring about necessary changes to our industry.

We have three overarching aims:

1. Decarbonise Now

We seek to radically transform the regulatory, economic and cultural landscape in which our built environment is made, operated and renewed in order to facilitate rapid decarbonisation of the built environment.

2. Ecological Regeneration

We advocate the immediate adoption of regenerative & ecological principles in order to green the built environment, prioritise communities and ecosystems at threat and promote the recovery and restoration of natural environments.

3. Cultural Transformation

We call for a complete remodelling of our professional culture. We must challenge and redefine the value systems at the heart of our industry and education system. We seek to create an open network to share resources and knowledge to aid in this transition.




By creating a network of engaged and active practitioners we aim to create change through;


Political campaigning & lobbying

Direct action & public engagement

Research & knowledge sharing

We welcome anyone that shares in this vision for change

Acan is running an urgent campaign until 13th april:

The UK Government is currently seeking views on the ban of the use of combustible materials in and on external walls of buildings, with any changes affecting the safety and structure of every new building in the country above 11m (circa 3 storeys). Comments are being received until 23:45 on Monday 13th April.

ACAN is concerned about the effect the proposals will have on the use of structural timber, and is calling on the profession to respond to the consultation to save safe structural timber.
