Supplier LoCT is a supplier engagement initiative to help suppliers understand their carbon footprint, set science-based emission reduction targets, take action, and disclose progress through a series of courses and assignments.

The programme was launched in late 2020 by Mars, McCormick, and PepsiCo and brings a unified ask to (often) shared suppliers to incentivise climate action and target setting. As of Spring 2022, the Supplier LoCT comprises a community of 12 brands, with approximately 500 suppliers to date.
