The strategy is guided by a compass shared with shareholders, which includes objectives for growth, positive societal impact, and reputation.

What challenges does Mars face in its sustainability efforts?

The primary challenge for Mars lies in the complexity of engaging with its vast supply chain, particularly with farmers who are essential for sourcing ingredients sustainably. Weihrauch mentions that scaling sustainable practices across a global enterprise is difficult, as it requires not only technical knowledge but also a commitment from various stakeholders involved in the supply chain to adopt these practices.

How does Mars balance short-term and long-term objectives?

Weihrauch illustrates the need to balance short-term results with long-term vision by likening business operations to a marathon run in sprints. He argues that while long-term planning is crucial, businesses must also deliver short-term results to satisfy their stakeholders. This dual focus allows Mars to navigate immediate pressures while still prioritizing sustainable growth.

Weihrauch asserts that the issues related to climate change are not political but fundamentally economic and agricultural.
