To counter political backlash against ESG, Mars' CEO reframes sustainability as a fundamental business imperative. For a food company reliant on agriculture, climate change directly threatens crop viability and affordability. This makes environmental action a matter of operational resilience and risk management, completely separate from political debate.

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.

The debate over food's future is often a binary battle between tech-driven "reinvention" (CRISPR, AI) and a return to traditional, organic "de-invention." The optimal path is a synthesis of the two, merging the wisdom of ancient farming practices with the most advanced science to increase yields sustainably without degrading the environment.

Over the past 50 years, Americans have reduced per capita beef consumption by a third by substituting it with chicken. This seemingly simple dietary shift has inadvertently cut more emissions than any other climate action before the rise of solar power, highlighting the massive climate leverage in reducing beef production and its associated land use.

The obesity crisis is a systemic issue, not an individual failing. The modern food environment promotes overconsumption of unhealthy foods. Critically, the U.S. agricultural system does not even produce enough fruits and vegetables for the population to follow recommended dietary guidelines.

While often romanticized, a widespread shift to pre-industrial, low-yield organic farming would be a climate disaster. The core environmental problem of agriculture is land conversion. Since organic methods typically produce 20-40% less food per acre, they would necessitate converting massive amounts of forests and wildlands into farmland, releasing vast carbon stores.

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.

Despite shelves stocked with heirloom tomatoes and exotic grains, our core food supply is dangerously uniform. For example, 90% of U.S. milk comes from a single cow breed descended from just two bulls, and half of all calories consumed globally come from just three grasses.
