Guide for City Staff

Green purchasing, also known as environmentally preferable purchasing, aims to identify products with lesser impact on human health and the environment compared to conventional products. In San Francisco, we lead by example. San Francisco's landmark Environmentally Preferable Purchasing/Precautionary Purchasing Ordinance requires that City staff buy only green products. These products are listed as "Required" on this website.  This ordinance applies to all purchases: direct purchases, service contracts and delegated/Prop Q purchases (anything under $10,000).

The lists of City approved vendors on this site are not comprehensive.  Check with your finance staff for an up-to-date list.

This page provides information to help San Francisco city departments meet this mandate in a way that saves money and improves City employee health:



Required products meet City requirements for environmental and health impacts, performance and cost. For product categories below, City departments must see links below for compliant products and criteria that products must meet:

Automotive Fluids

Building supplies

Cleaning Supplies


Cleaning supplies


Food & Foodware


Lighting (ballasts, fixtures and bulbs)

Office supplies

Personal care 


In addition, city staff are encouraged to use Suggested products. These are products that meet city requirements for environmental and health impact, but lack complete performance and cost data.


Limited use products are products that are allowed only in special circumstances. 

Never Choose:



Products that do not appear on webpages of Required product categories above should be considered as prohibited.  In addition, some product categories are explicitly Prohibited due to specific legislation. 

See a partial list of Prohibited products.  


Improve green purchasing

The success of the City's green purchasing depends heavily on dedicated staff in all city departments. The best way to help the city's green purchasing efforts is to:

  1. Stay up to date on the latest in city green purchasing by signing up for our newsletter.
  2. Remind other City staff to do the right thing: by email, department newsletters, purchasing forms, and staff handbooks.
  3. Use this site for choosing and rating products.
  4. Sign up to test Suggested green products to help other city staff.
  5. Ask SF Environment for assistance.

City's green purchasing legislation

The City's Environmentally Preferable Purchasing Ordinance is based on the Precautionary Principle, which is now the first chapter of the Environment Code. The environmental specifications for most of the products on this site are further spelled out in regulations. Other City ordinances that require green products can be found elsewhere in the Code:

  • Integrated Pest Management Ordinance (Env. Code, Chapt. 3): Limits the use of pesticides (as a last resort) to products on the City's Reduced Risk Pesticide List
  • Healthy Air and Clean Transportation Program (Env. Code, Chapt. 4): Regulates the purchase of green vehicles for City fleets.
  • Resource Conservation Ordinance (Env. Code, Chapt. 5): Establishes requirements for recycled content paper and PVC plastics.
  • Green Building Ordinance (Env. Code, Chapt. 7): Requires LEED certification for municipal construction projects, which involves a variety of energy efficient, low-toxicity, and water efficient products.
  • Tropical Hardwood and Virgin Redwood Ban (Env. Code, Chapt. 8)
  • Arsenic Treated Wood Ordinance (Env. Code, Chapt. 13): Limits the use of arsenic-treated wood

By buying Required products, city staff help us meet our mandate while also saving money.
