The Warren is a management consultancy and ESG advisory practice focusing on the intersection between sustainable finance and corporate sustainability and the urgent need to transition to a low-carbon, circular economy. We believe that science driven Big Data will be key to making sustainability tangible for financial institutions and are exploring various avenues for progress on this topic.

We offer a range of management consulting services, including ESG strategy development for corporate clients and financial institutions, ESG advisory on investment policies, second party opinions on green bonds, or development of appropriate sustainability performance targets in the context of ESG linked loans.

We also offer reporting services, from complete annual sustainability reports to ongoing reporting on the use of proceeds for green bonds.
