What We Do
Delivering a commercially smart climate transition.
To reach net zero carbon emissions by 2050, the world must halve its emissions in this decade. While climate ambition is growing, we remain significantly off track to deliver on this goal.
It is time to turn climate intent into action.
Corporations need to transition at pace and at scale, and within the normal pressures of sustaining and growing a profitable business.
Oliver Wyman helps clients pursue a commercially smart transition, enabling leadership teams to deploy their financing, operating capabilities, and customer relationships to achieve outcomes they were never designed for.
We bring together deep industry and functional expertise from across Oliver Wyman, the Oliver Wyman Forum, and Marsh McLennan to break down climate transition challenges and bring a competitive edge to clients.
Oliver Wyman and CDP Europe have published five major reports analysing the progress and shortfalls of Europe's path to net zero, drawing on CDP's comprehensive self-reported environmental data and Oliver Wyman's analytical rigour. The strategic insights and corporate case studies highlighted in these reports can help senior executives understand and act on their climate and nature-related impacts.
Oliver Wyman is supporting the World Economic Forum as a knowledge partner on a broad range of initiatives including, Financing the Transition to a Net Zero Future, Sector Transitions to Nature Positive, and the Partnership for Advancing Health in Climate Action. These initiatives have engaged a multistakeholder community of financiers, industry stakeholders, philanthropists and public institutions to unlock opportunities for a net zero and nature-positive future.
Oliver Wyman served as the knowledge partner to the GFANZ Secretariat. Since launching in 2021, more than 450 financial firms, from 45 countries, responsible for more than $130 trillion in financial assets, have committed to aligning their operations and financing with achieving 1.5°C. GFANZ has published five major reports which help financial institutions translate their net zero pledges into actionable, near-term and science-based transition plans.
Oliver Wyman worked with UNEP FI to develop common analytical tools – including scenarios, methodologies and metrics – for banks to strengthen their assessment and disclosure of climate-related risks and opportunities. This will enhance their ability to implement the TCFD recommendations and promote consistency and comparability in climate change assessments and disclosures across the sector.
