Many large listed companies in Switzerland have made significant progress on sustainability measurements and disclosures.
What’s often missing is a clear path from that data to the decisions that matter for a business. Quinn Wenning, Senior Manager – Sustainability & Climate at Deloitte in Switzerland, works on creating that path, and his assessment is: the problem is not the data itself, it’s how it translates into business decisions.
As one of Switzerland’s leading professional services firms, Deloitte Switzerland advises companies on complex business challenges, including sustainability, across audit and assurance, consultancy, tax, legal, and risk. According to their State of Sustainability Reporting FY25 market study, about 96% of top companies in the Swiss index have Scope 1, 2, and at least partial Scope 3 coverage.
“The question isn’t only how do we get better data, though that’s clearly part of the challenge. It’s how do we get the right data into the rooms where the decisions are being made,” says Quinn.
This framing defines Deloitte’s approach to sustainability consulting. It points to a problem that is fundamentally about language.
