Prior to her current role, Laurette managed WBCSD’s Partnership for Carbon Transparency (PACT) Ecosystem team, which alongside its stakeholder ecosystem, has developed the global standard for calculating and exchanging primary, product-level Scope 3 emissions data along supply chains, enabling companies to make emissions-informed decisions and accelerate decarbonisation.
