Mars Sustainability Actions

Published sustainability reports

Mars has published annual sustainability reports and related disclosures that track progress across climate, people, packaging, sourcing, and human rights. Its 2025 report says the company has been reporting on its Sustainable in a Generation plan since 2017. The reports include data on greenhouse gas emissions, water use, packaging design, supplier programs, and progress on healthier meals. This gives readers a clearer view of what the company says it has done and where it still has work to do.

Cut emissions across its value chain

Mars says it reduced absolute greenhouse gas emissions by 16.9% across its full value chain from a 2015 baseline while growing the business by about 75%. It also says it achieved a 42.6% cut in Scope 1 and Scope 2 emissions. Scope 1 means direct emissions from its own operations, and Scope 2 means emissions from purchased energy. The company says this progress supports its path to net zero by 2050.

Expanded renewable electricity use

Mars says it has started scaling renewable electricity across its full value chain through its RAcc program, which is short for Renewables Acceleration. It also says it has transitioned 58% of its operations to renewable electricity and is aiming for 100% by 2040. This matters because switching to cleaner power can lower emissions from factories, offices, and other operations.

Reduced land-use pressure

Mars says it has worked to redesign supply chains linked to deforestation and ecosystem conversion in beef, cocoa, palm oil, pulp and paper, and soy. It reports an 8.6% reduction in land use linked to its value chain compared with 2015. The company says it follows the Accountability Framework Initiative, a set of rules used to guide deforestation-free sourcing. It also says it is a member of the Consumer Goods Forum Forest Positive Coalition.

Improved packaging design

Mars says it is redesigning packaging so it can be reused, recycled, or composted more easily. In its 2025 reporting, it says 67.6% of consumer-facing packaging was designed to be reusable, recyclable, or compostable. It also says it is investing hundreds of millions of dollars in packaging redesign and is trying to match packaging with recycling systems that already exist or are likely to exist soon.

Expanded supplier human rights work

Mars says it has worked with first-tier suppliers since 2011 to improve sustainability performance. It uses a Supplier Code of Conduct and says it checks risks using third-party data, audits, and outside partners such as Verité, a human rights group that helps assess labour risks. The company says this work covers human rights, environmental standards, and ethics in its workplaces and supply chain.

Monitored cocoa labour risks

Mars says it has expanded child labour monitoring and remediation systems in its cocoa supply chain. It also says it supports traceability in cocoa sourcing and has worked on the Living Income Differential, a fee meant to help cocoa farmers earn more. These steps are aimed at making cocoa sourcing more transparent and at reducing labour risks in a supply chain that is often linked to poverty and child labour concerns.

Published healthier food progress

Mars says its Food & Nutrition business delivered 3.4 billion healthy meals and reduced sodium by 3.9% compared with a 2019 baseline. It defines healthy meals using its own nutrition criteria. The company also says it tracks marketing compliance, with 99.67% media placement standards compliance and 99.4% media content standards compliance. This shows it is measuring both product nutrition and how it markets food.
