Because we are passionate and motivated to contribute to genuine, long-lasting sustainability across environmental, social and financial spheres, we take businesses beyond sustainability compliance.

Our services are delivered using a bespoke approach to our clients’ needs, spanning compliance fulfilment, business and human rights due diligence, sustainable and ethical procurement, sustainable business strategy and developing training, guides and tools.

What Our Clients Say

Working with Colleen is like a breath of fresh air. She applies a common sense approach with a clear level of intellectual ability. The achievement of the clients objectives were always at the forefront of our discussions. Her preparation of documentation, for example the preparation of a highly technical analysis of an Environmental Impact Assessment was both timely and of a very high quality.
Franscesca Da Vita, ASB Law
“After approaching Colleen with regards to providing bespoke training for
the Welsh Rugby Union and the Millennium Stadium in sustainability, we discussed our needs and she put together a training package tailed towards
our goals. Colleen delivered the training to our staff with great success and the outcome generated knowledge, understanding and enthusiasm within all of the
staff which was instrumental in our move towards BS8901 and subsequently ISO20121.”
Darren Crossman – Facilities Manager, Millennium Stadium
“The value of implementing ISO20121 was the creation of a system with principles that are becoming fully implemented into every aspect of our business. We have been able to fully take control of the sustainable event management system and work to continually improve it utilising internal resource and furthering stakeholder engagement effectively. CLT envirolaw was able to set the course for UBM Live to expand our sustainable event management system to flourish globally and to reach more parts of the business.”
