Our Culture


Carbon Neutral Certified

Oliver Wyman is certified as a CarbonNeutral® company as of June 1, 2020, and has also set in motion a long-term strategy to integrate sustainability into our operations and the way we work. Read more about our commitment here.

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

Tackling India’s energy shortage and increasing demand by enhancing renewable energy capacity

Delivering essential renewable energy capacity in a country with rapidly growing greenhouse gas (GHG) emissions

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

Developing sustainable infrastructure by preventing large amounts of idling emissions from being released into the atmosphere

Earth Day

We try to treat every day like Earth Day, but we do take time in April to promote climate action through a variety of sustainability-related activities.  Our colleagues' Earth Day actions and celebrations for 2020 moved online, so we are glad we can look back to last year when we asked teams in six of our regional office Green Champions to share updates on their most recent projects. Watch below how teams in San Francisco, Houston, Munich, and Dubai are demonstrating and promoting sustainable behavior at work and beyond.

Green Champions

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:
