Carbon Neutral Certified

Oliver Wyman is certified as a CarbonNeutral® company and has also set in motion a long-term strategy to integrate sustainability into our operations and the way we work. Read our commitment and learn about what's next including Marsh McLennan’s commitment to become carbon neutral throughout all its global operations in 2021, our alignment to the UN Sustainable Development Goals, and our plans to reduce carbon emissions by 15% below 2019 levels by 2025.

Carbon Offset Project Portfolio

To offset the emissions we could not reduce, Oliver Wyman worked with Natural Capital Partners to conduct an extensive review of offset projects and selected a diversified portfolio that reflects our values, global footprint, and the projects’ opportunity for impact. We are proud to support the following projects:

Distributing free solar cookers to low income households, bringing health and financial benefits to more than 300,000 people

Protecting 65,000 hectares of forest by engaging local communities through education and agroforestry training

Reducing the environmental impact of a landfill site through methane capture, electricity generation and wetland enhancement

Our internal sustainability network, Green Champions of Oliver Wyman (GROW), is leading efforts to integrate sustainability into all aspects of the firm, from organizing volunteer events to improving recycling practices to promoting our annual Earth Month activities. Our Green Champions in action:
