A credible and scalable standard, making it easier for you to calculate and exchange Scope 3 data

Neutral, not-for-profit initiative

With member companies from all business sectors and all major economies, and as the co-convenor of the GHG Protocol, WBCSD’s neutral position ensures trust and a common vision and strategy to decarbonize across supply chains and industries.

Ensuring data sovereignity

Each organization is the sole owner of and exercises sovereignty over its data, with full control over who has access to any data-point. The granularity of the data exchanged and the tool with which it is exchanged is chosen flexibly in line with PACT requirements. The technology is accompanied and supported by a governance framework that further strengthens the data sovereignty of each stakeholder.

Applicable and actionable

Organizations simply cannot track and reduce what they cannot measure, putting at risk the achievement of their net zero targets. By enabling access to granular, consistent, and actionable supplier data in a scalable way, PACT allows step-by-step and fit-for-purpose integration to enable business decisions.

Created through collaboration

By bringing together a growing number of stakeholders across value chains and industries as well as standard-setting bodies, leading technology companies, reporting organizations and regulators, PACT drives exchange, alignment and integration.
