It’s hard to reduce what you can’t quantify. Watershed’s platform measures and reports carbon emissions throughout companies, with an update this year to include their supply chains as well. Its detailed carbon footprint maps set the stage for specific reductions and broader decarbonization initiatives. “Climate change is basically a math problem,” says Watershed cofounder Taylor Francis. After connecting to companies’ business operations to gather and analyze data, the startup produces a dashboard showing how much carbon is being emitted and from where. Watershed is already working with some of the world’s largest companies to help reduce their carbon impact, including Stripe, Walmart, and Airbnb, and now also works with asset managers and financial institutions to calculate the emissions from their investing, lending, and portfolios.
