Our Facility Environmental Policy

Our facility sustainability commitment

Mars’ ambition is to make our facilities Sustainable in a Generation (SiG). This means achieving a zero carbon footprint, eliminating the impact of waste, and ensuring that our water use is at sustainable levels by 2040. The more our business grows, the more of a challenge this will become. Our goal is to reduce total greenhouse gas (GHG) emissions from our facilities by at least 3% each year, regardless of business growth. Our policy is to send no operational waste to landfill from our factories, with this milestone being achieved in December 2015.

At Mars, Incorporated, our Five Principles are the foundation of our Facility Environmental Policy. While we are required to meet environmental legal requirements everywhere we operate (as well as other standards, internal and external) our aim is to go beyond mere legal compliance by continuously improving our environmental management and performance through our Global Environment Management Standards, and related Risk Management and Control Standards.


We will communicate our Health, Safety and Environmental policy by ensuring it is displayed at each Mars facility, and apply it by:

  • Providing strong governance through a Mars Leadership Team Health, Safety and Environmental sponsor, a Global Health, Safety and Environment Leadership Team and other competent environmental resources.
  • Providing the necessary resources to build capability and competence to effectively manage environmental risks, through standards and audit processes.
  • Implementing an effective and documented Environmental Management System and continually reviewing and improving it.
  • Identifying environmental hazards and assessing risks, resolving them in a timely way to ensure they are minimized, avoided or adequately controlled.
  • Setting objectives, targets and plans that continually reduce environmental risks and hazards.
  • Ensuring our facilities and equipment are designed, installed, operated and maintained in an environmentally safe manner.
  • Ensuring Associates and others who work with us are competent to fulfil their tasks through the provision of supervision, information, instruction and training.
  • Empowering Associates and others working with us to stop anyone on site from inadvertently or deliberately breaking environmental procedures or standards and providing arrangements to consult with and enable Associates and others working with us to raise environmental issues and contribute to their resolution.

In return, Mars expects all Associates, suppliers and visitors on company business to conduct themselves in an environmentally safe manner (whether on or off company property), to comply with all applicable Mars policies and promptly report any environmental hazard(s).

Facilities management

One key information source is our Global Facilities Manual which guides the design of new facilities and helps to deliver the four pillars of our SiG program.

  • Operational efficiency: Driving down energy, water and waste by changing behaviour and practices.
  • Capital efficiency: Investing in more efficient equipment and processes.
  • New technology: Developing and deploying innovations that enable step change.
  • Renewable energy: Working with partners to deploy renewable energy.

Guided by what we have learnt from the most successful improvement initiatives implemented in Mars factories over a five-year period, the Confectionery, Pet and Food segments have developed SiG playbooks that detail the operational and capital efficiency activities that production facilities should follow to reduce their energy, water and waste impacts. It is our intention to ensure that these are included in the operational and equipment design scope of new facilities so that their efficiency is optimized from the start of production operations.

Our intent is to develop all new green-field facilities in line with Mars’ commitment to the elimina­tion of facility fossil energy use before 2040. On and off site renewable energy solutions for the site’s electrical and thermal energy requirements should be investigated as part of the facility development process with the help of the Corporate Renewable Energy Team.

All significant Mars construction and new facility building projects (>1000m2) will pursue LEED. Offices will target LEED Gold certification, while production and other buildings will target Silver under LEED V4.

Mars has global standards in place intended to ensure our manufacturing facilities’ engineering, maintenance and production teams successfully implement our policies, commitments and procedures for environmental impacts including air and water quality, and waste management.

Suppliers to our facilities

Our Supplier Code of Conduct requires each supplier, including third-party manufacturers, to comply with all applicable environmental laws and regulations, and to continuously strive to improve environmental performance.

The Code also contains additional guidance to encourage suppliers to document and maintain environmental compliance records; properly handle, store and dispose of hazardous materials and wastes; ensure staff are informed and trained on environmental management, and minimize and monitor their impact on the environment where possible by reducing GHG emissions, increasing energy efficiency, and reducing and recycling natural resources including water and paper / packaging materials.

New projects, products, raw materials and packaging supplied to our facilities

Our Project Review Process (PRP) is a robust review system that addresses environmental and sustainability aspects and impacts associated with projects or changes to Mars equipment, processes, and facilities. The PRP is designed to ensure that effective controls are "designed and built into" Mars engineering and maintenance activities.

The process requires the evaluation of environmental and sustainability risks in each phase of a project through a documented risk assessment. The process provides an early identification of risks, thorough discussion of these issues, and the application of corrective actions. The results of the successful completion of the Project Review Process include equipment, processes, and facilities that meet or exceed Mars environmental standards and regulatory requirements.

As one of the world’s leading food manufacturers, Mars has a duty to help our agricultural suppliers to produce more with less. By helping the suppliers and farmers who produce our raw materials to improve yields and crop quality, we can help improve their incomes while developing more sustainable products. This work is outside the scope of this policy, and is instead covered in a series of complementary public position statements on Mars’ impacts on Climate Action, Water Stewardship and Land Use across its value chain.

The Mars, Incorporated Packaging Design Sustainability Guidelines take a holistic approach to packaging design that includes the entire packaging system from sourcing to end of life. Our goal is to utilize the right level of product protection, which meets business needs, ensures the highest quality standards for consumers, and considers the environmental and social impacts of the package’s life cycle.

To reduce the use of virgin fiber in our packaging, we will maintain a preference for recycled fiber where feasible and where we believe it to be a more sustainable alternative to virgin fiber. The final choice of fiber will be determined by quality and food safety requirements, product specification and performance, legal requirements, and its sustainability impacts. Our pulp & paper-based materials sourcing & deforestation policy sets out full details.

Responsibility and authority

Associates, contractors, and visitors all help improve workplace quality by ensuring that environmental risks and hazards are controlled or eliminated. Associates with management responsibilities are accountable to execute the Heath, Safety and Environmental Policy within their areas – to ensure protection of the environment. Company policy requires immediate response to any report of an environmental incident and quick action to address the issue.

Mars relies on all associates to take direct responsibility for environmental issues within their control. They are expected to conduct themselves safely and observe Mars environmental practices. Associates must be alert to identify hazards and initiate remedial action to correct unsafe behaviors or conditions in a timely manner. All associates have the authority to direct any other associate, contractor, or visitor to stop any action that violates Mars policies or procedures. Associates or others who violate policies or procedures are subject to disciplinary action.

Review and evaluation

Mars measures environmental performance by analyzing key performance indicators, reviewing inspection reports, and auditing the environmental management system. These measurements allow us to develop objectives, targets, and plans with aims of eliminating and controlling environmental risks. Management will periodically review, evaluate, and verify facility performance to continually improve environmental processes.

Following mergers and acquisitions, full history data for the newly acquired business are included in Mars’ impacts reporting, going back to Mars’ base year (or the first year of operation of that business if later than base year). If full historical data is unavailable, it is estimated based on available data (i.e., proportional to production).

The Mars Sites Periodic Reporting Data Manual documents and guides Mars’ global sustainability data collection activities for our facilities. It provides definitions and details for the environmental impact data we collect, and describes how associated calculations (e.g. greenhouse gas emissions) are performed.

As a due diligence measure, we engage an independent auditor to provide limited assurance of our annual facility sustainability data in accordance with the AA1000AS Assurance Standard and ISO 14064-3: Specification with guidance for the validation and verification of greenhouse gas assertions.

This policy will be reviewed every two years to ensure it continues to accurately reflect Mars’ commitment and procedures.
