LewisSustainable is an independent consultancy that helps businesses and individuals to assess and quantify their carbon footprint, develop strategies for reducing it, and implement these strategies effectively by using the 'Theory of Change' process. We are the UK affiliate of ActKnowledge NYC - leaders in TOC development, application and training.

We provide the 'EcoSet' - which is not an 'offset' but an investment vehicle for your carbon emissions. It converts your footprint into funds that will support ecological restoration projects in communities vulnerable to climate change. It aims reduce your carbon emissions quickly, stimulate innovation and create the potential for new commercial advantage for your business.

Our services are designed to be flexible. We can tailor a bespoke package to meet your particular requirements, utilizing any of our services as appropriate, or even undertake research to help you clarify your objectives.
