While a major contributor to emissions, the agricultural industry is also more vulnerable to climate change impacts than almost any other sector. This dual role as both primary cause and primary victim creates a powerful, intrinsic motivation to innovate and transition from a "climate sinner to saint," a dynamic not present in all industries.

To address its largest emissions source (Scope 3), Mars goes beyond farmer engagement by re-engineering its products. Scientists use a dedicated IT system to reformulate pet food, optimizing for both animal nutrition and environmental impact by prioritizing lower-impact proteins like poultry over beef, tackling the problem at the R&D level.

To operationalize its commitment to sustainability, Mars initially moved responsibility for the function into its Finance department. This organizational design choice ensured that sustainability investments and progress were reviewed with the same scrutiny and integrated into the same planning cycles as the company's core financial P&L.

The way we grow food is a primary driver of climate change, independent of the energy sector. Even if we completely decarbonize energy, our agricultural practices, particularly land use and deforestation, are sufficient to push the planet past critical warming thresholds. This makes fixing the food system an urgent, non-negotiable climate priority.
