Sign Charter

We have changed our Charter from August 2013 as below.  Please sign up to our new Charter and make a donation of your choice. 


Cornwall Sustainable Building Trust

"CSBT Charterers have the common aim of making all areas of construction sustainable, by seeking the best environmentally sustainable option and sharing best practice and knowledge."


Suggested donations: as a guide we suggest:

£25 - £50 for smaller companies and sole traders 
£250-£500 for companies with 50-100 employees
£500-£1000 for large companies with over 100 employees

We are keen not to exclude anyone from signing the Charter on grounds of cost.
If you would like to sign up to our Charter, but are not in a position to make a donation,
please email, and she will sign you up.
