Responsible Purchasing

Stanford Procurement Services is committed to the university’s mission to deploy its strengths to benefit our region, country and world, as well as to the sustainability goal of Zero Waste by 2030. Responsible purchasing is a key component to achieving these goals, and these guidelines are meant to advise, guide and encourage university consumers and suppliers alike to act responsibly when involved in purchasing activities at Stanford.

Responsible Purchasing is the acquisition of goods and services that meet the business and research needs of the consumer while also being environmentally-friendly, socially responsible and ethically-sourced. The purpose of these guidelines is to support and facilitate the purchase of products and materials that minimize the harmful effects from their production, transportation, use and disposition. It is Stanford's preference to purchase and use environmentally preferable products whenever they perform satisfactorily and can be acquired at similar total value. The policy applies to all Stanford University purchasers and suppliers. 

Procurement Services

Stanford Procurement Services promotes the use of environmentally preferable products, practices and suppliers by developing and implementing university-wide preferred supplier contracts and product standards. Stanford Procurement Services recognizes the university community's responsibility to minimize any negative impacts on society, human health and the environment, while also meeting various business requirements.

Specifically, Stanford Procurement Services supports responsible purchasing through:

  • Partnerships with the Office of Sustainability and school and unit departments to develop and implement responsible purchasing solutions that fit the needs of the university
  • Programs such as Cardinal Print that focus on high-volume, high-impact solutions to purchasing needs
  • Processes that incorporate sustainable purchasing practices into how the university does business (i.e., through contracts and vendor management)
  • Data Analysis across spend categories that informs buying decisions and measures efforts toward the university's goals


Each member of the Stanford community has choices when it comes to purchasing that can have a meaningful impact on the world. It is the entire university community's responsibility to minimize any negative impacts on society, human health and the environment, while also meeting various business requirements. In keeping with Stanford's commitment to the environment, departments should adhere to the responsible purchasing guidance whenever possible. Consideration should be taken for the purchases’s environmental impact, including but not limited, to the financial and environmental cost of manufacturing, transporting and disposing of the product. 


Stanford encourages partnerships with suppliers who adhere to the responsible purchasing guidance at a competitive price.

In keeping with Stanford's commitment to the environment, departments should adhere to green purchasing practices whenever possible, taking into account the environmental impact, including but not limited to, the financial and environmental cost of manufacturing, transporting and disposing of the product. 

United States Environmental Protection Agency (EPA) Guiding Principles

  • Include environmental considerations as part of the normal purchasing process
  • Emphasize pollution prevention early in the purchasing process
  • Examine multiple environmental attributes and costs throughout a product or service's life cycle
  • Compare relevant environmental impacts when selecting products and services
  • Collect accurate and meaningful information about environmental performance and use it to make purchasing decisions

Purchasing Considerations

Stanford purchasers should consider these questions when making a purchase:

  • Is the product or service really necessary?
  • Must it be new, or can an existing product be reused/repurposed to fulfill the need?
  • How will it be disposed of? Is it recyclable, reusable, compostable or biodegradable?
  • Is the product energy efficient compared to competitive products?
  • Are the packaging components recyclable? (At Stanford, cardboard and thin film plastic are recyclable; Styrofoam is not).

And, at a deeper level:

  • What material is the product made of?
  • What negative upstream or downstream effects might this product have?
  • Under what conditions were the product manufactured? For instance, were fair and ethical labor practices used in the manufacturing process or supply chain?
  • How has the product been transported and delivered? How far has it travelled?

To support responsible purchasing at the university, Stanford Procurement Services provides guidance by purchasing category. The Stanford community can learn more about common purchasing categories and sustainable purchasing methods in the Responsible Purchasing Guidelines handbook.


All purchases of paper products, including both office and janitorial, should either be made from 100percent recycled content or be Forest Stewardship Council (FSC) certified. Products made from recycled paper not only prevent trees from being cut down, they require up to 30percent less energy and 50 percent less water to produce than non-recycled paper.

Office and Breakroom Supplies

Many office products (e.g., binders, pens, staplers, etc.) are disposed of before reaching the end of their useful life. Therefore, Stanford personnel should first check to see if the need can be fulfilled with reused items. Because office supplies are highly consumable, the most important sustainability aspect is keeping used materials out of the landfill, through the purchase of products that are recyclable and products made with recycled content.

Breakroom supplies include service ware, such as cups, plates and utensils, accounting for a high level of waste and negative impact to the environment. Reusable service ware is the most responsible purchasing option. If disposable service ware is required, compostable items should be purchased. Compostable items turn into soil in 45 days at a commercial composting facility.

Lab Supplies

Reusable options for lab consumables, such as pipette tips and boxes, gloves, media bottles, etc. are becoming more available and are often less expensive. For example, instead of purchasing new pipette tip boxes every time, one can reuse the boxes and purchase refillable tip racks, which are up to 70 percent cheaper. The Cardinal Green Labs program hosts a lab share event every fall and spring to facilitate reuse between labs. For supplies that cannot be reused, labs should purchase recyclable options where available and arrange for used items to be dropped off for recycling at key locations on campus.


Before purchasing new chemicals, purchasers should check with Stanford's Surplus Chemical Inventory. Through this program, Environmental Health and Safety (EH and S) delivers free chemicals to labs within 24 hours. Purchasers and lab managers are encouraged to use Stanford’s Chemical Inventory Management and Tracking System, ChemTracker, which ensures good inventory management practices and can lead to cost savings from avoiding duplicate purchases.

Electronic Equipment

Purchases of electronic equipment should be EPEAT certified. EPEAT is the most comprehensive sustainability certification for IT equipment (E.g. computers, monitors, TVs) evaluating a number of different attributes, including materials sourcing, environmental safety during production, energy consumption and end of life. A laptop computer that is EPEAT certified uses 42 percent less energy, contains 25 percent more recycled content and contains 89 percent less toxic metals than a non-EPEAT computer. In the past few years, 100 percent of Stanford’s electronics purchased through its major suppliers have been EPEAT certified. EPEAT provides model contract language that can be included in requests for proposals.

Non-IT equipment purchases should be Energy Star certified. Energy Star is the most robust and prevalent sustainability certification for non-IT equipment. The certification is given to the most energy efficient models in each equipment category. Purchasing Energy Star will ensure that the equipment’s energy consumption and carbon footprint is as low as possible.


As furniture is often disposed of before reaching the end of its useful life, when purchasing furniture, Stanford personnel should first check the Stanford Reuse website to see if the need can be fulfilled with reused items.

New furniture sourced for Stanford should not include toxic chemicals. According to the U.S. Environmental Protection Agency, there are over 80,000 chemicals in use today, most are unregulated and only some have undergone sufficient health testing. Many of these toxic chemicals end up in furniture, specifically: Flame retardants, Polyvinyl Chloride, Volatile Organic Compounds, Fluorinated Chemicals and Antimicrobials. Recent research clearly links these chemicals to adverse health effects including cancer, interference with the hormone system, impairments to neurological development and reproductive harm. The Consumer Product Safety Commission claims that removing flame retardants and other chemicals does not compromise fire safety.
