Low carbon solutions for Welsh businesses and the public sector 

At Carbon Trust Wales, we strive to provide the best possible resource efficiency advice and guidance to the public sector and business.

As well as offering the full range of Carbon Trust services, we also offer a number of additional services specifically for Welsh organisations such as our 0% APR loans scheme for small to medium sized enterprises, and free resource efficiency support for public bodies in Wales. 

The Carbon Trust welcomes dealing with customers and other stakeholders in both Welsh and English and is committed to providing an equally effective standard of service in both languages so far as is appropriate in the circumstances and reasonably practicable.

How we can help your business

We support businesses across Wales, from large companies to small- and medium-sized enterprises (SMEs), as they tackle their energy costs, their carbon footprint and make moves towards a sustainable, low carbon economy.  We can also provide support through our online technical content, publications and web tools.

How we support the public sector

We've worked successfully with almost all of Wales' local authorities, health boards, universities and colleges, and government and its agencies. This experience has enabled us to create a collection of approaches to help organisations identify, prioritise, plan and implement energy and cost-saving projects. 

Our services are specifically designed to meet the needs of the Welsh public sector, working with our clients to accelerate the implementation of resource efficiency programmes, maximising benefits and minimising risk.

As well as offering the full range of Carbon Trust public sector support services, we also offer a number of additional services specifically for Welsh public bodies, including the Welsh Government Energy Service.

Refit Cymru, Welsh Government logos

This includes free support to assist public bodies in Wales to identify opportunities for resource efficiency and renewable energy measures and support organisations as they move towards implementation. 

We work in partnership with a range of additional Welsh Government funded support services designed to accelerate the transition to a sustainable, low carbon public sector in Wales including The Wales Funding Programme and Re:fit Cymru.
