Cambridge based, globally focused
WeESG was founded by former colleagues from the University of Cambridge’s Centre for Sustainable Finance. As finance practitioners they recognised how regulation and client demand was shifting the focus of sustainable finance away from a niche offering to something all institutions had to embrace. However, they had concerns that training, available across the market, was insufficient in providing the actual knowledge and skills needed to fully implement the changes required.
Our mission is to ensure the success of sustainable finance by providing market leading skills development for all financial institutions, multilateral development banks, corporates – and their key stakeholders.


Programmes that deliver the client needs
Delivering programmes designed to meet an institutions unique sustainable finance training needs, has meant that the global WeESG team has now trained over 25,000 practitioners, across 200 institutions, in over 35 countries. This includes many of the most recognisable financial institutions.
Following the launch of a partnership with the Cambridge Institute for Sustainability Leadership (CISL), to blend sustainability leadership and skills development, WeESG moved into its new home at The Entopia Building, a multi-award winning sustainable building retrofit project in central Cambridge.
