Carnstone is an independent management consultancy, specialising in corporate responsibility and sustainability.

We advise clients on the full range of social, environmental and ethical topics – from supplier management to community investment, from environmental modelling to corporate governance. We have offices in London and Shanghai.

We work mainly for large companies - also for NGOs and charities - and we have known many of our clients for years. We help set strategy, we do research, we run projects and frequently we're just there at the end of the phone for some quick advice.

We're an equity partnership, with a strong culture of employee engagement, transparency and internal debate. Our team comes from a wide range of backgrounds; different countries and sectors. We have worked in-house in large companies, and many of us have been involved in this field since its beginning.
