about SUSTaim


SUSTaim is an advice, assessment, research, and knowledge transfer service founded and lead by John Easton.

The service delivers guidance from dedicated specialists who have the knowledge, skills, and experience to provide practical support for the definition and achievement of our sustainable futures.

SUSTaim's services extend from management consultancy - supporting organisational change through policy and procedures development, training and knowledge transfer, through the provision of sustainable design and technical advice, to impact assessment including carbon foot-printing and BREEAM.

SUSTaim's services are underpinned by direct involvements in academic research into climate change and sustainable development, and its advice and assessment services are delivered through programs accredited by Carbon Trust, CIBSE, and the Building Research Establishment.

SUSTaim's expert services can assist you to comply with fast changing regulations, understand and meet relevant sustainability benchmarks and targets, save energy and resources, and reduce carbon emissions and running cost.

Frequently the savings made will exceed the cost of the service, and some of our services are grant fundable as well.

Company History


SUSTaim is a private limited company formed in 2008 by architect John Easton, registered in Scotland and operating throughout the United Kingdom and Ireland.


SUSTaim’s services are informed by 30 years of experience in commercial private practice involving the design and implementation of over 70 building and masterplanning projects to a total construction value in excess of £600M.


His interest and considerable knowledge in the field of climate change and sustainability has lead John over the last decade to develop a unique specialisation in these areas, and the establishment by him in 2006 of the sustainability expert group of one of the UK's top ten architectural firms, before moving on in 2012 to devote his time to SUSTaim.


SUSTaim maintains research and teaching involvements with a number of leading universities and business start-ups, ensuring that our services are informed by emerging sustainability best practice as it develops and by the latest technical advances as these are made.



SUSTaim is one of a new breed of small agile specialist companies that acts as a vehicle for flexible service delivery, including collaborative working with like-minded practitioners and academics who have complementary knowledge, skills, and experience in related areas.


SUSTaim can call where necessary on the support of experts of national and international standing across a range of sustainable development topics to further reinforce its own specialisms.


SUSTaim welcomes expressions of interest from like-minded practitioners and researchers to explore co-operative collaborative opportunities.
