There is a growing number of Standards in the fields of ESG. These are aimed at reducing the risk of greenwashing; they aim to provide investors and customers with a firmer guarantee of responsible corporate conduct.

ESG Gap Analysis Against Standards

The proliferation of Standards has resulted in increased complexity for ESG managers, executive leaders and Boards everywhere. It can be difficult to ascertain where effort is best placed to close the gaps that mean the most in a specific business context.

We bring our experienced practitioners to our Clients' teams to help them understand the gaps they need to focus on. We are familiar with requirements such as IFC/World Bank, ICMM, TSM, The Copper Mark and OECD.

Contact us to find out how your ESG maturity can gain the most impactful traction by focusing on the Standards and the gaps you most need to address.
