What is the City Doing?

Sustainability is woven into the City's daily operations - from procurement to file work. In 2007, emission reduction targets were established to further sustainability efforts and guide decision making and consistent with standards set by AB32. The City is close to meeting its target of reducing community emissions 15% by 2020. Most recently, the City has received an award for reducing its energy consumption by 5% through the installation of LED lights and other energy upgrades throughout the City. But, more can be done!

The City is an active member of the Marin Climate & Energy Partnership (MCEP), which includes representatives from all eleven Marin cities/ towns, and County, the Transportation Authority of Marin (TAM), and Marin Municipal Water District (MMWD) and the Marin General Services Authority (MGSA). Its mission is to reduce emission levels, with the partnership allowing for innovative discussion and coordinated work throughout Marin County. A recent example includes the adoption and implementation of the disposable bags.

Reusable Foodware Ordinance

The County of Marin has developed a Reusable Foodware Ordinance establishing regulations requiring the use of reusable and compostable food ware materials (e.g., plates, bowls, cups, utensils, and trays) at restaurants, grocery stores and delis, bakeries, carry-out, mini marts, farmers markets, food trucks, and other businesses requiring a health permit. The Ordinance prohibits the use of single-use plastic food ware items; proposes a $0.25 charge for disposable cups (with exemptions available for Cal Fresh/ SNAP and WIC customers); and establishes overall process for implementation and enforcement. 

On April 17, 2023 The City of Mill Valley adopted the ordinance and enforcement will begin on November 10, 2023. For more information, contact Grace Ledwith at or go to the County of Marin’s reusable foodware website

Electric Vehicles - Ride and Drive Clean! 

In Marin County, our passenger vehicles are the single largest source of GHG emissions, representing up to 50% of our individual carbon footprint. When you switch from a gas car to an EV and plug into clean energy, you are taking impactful climate action by reducing both carbon emissions and air pollution, both which disproportionately impact equity priority communities.

Save money, time, and improve your driving experience with an EV. Learn how to make the switch to an electric vehicle with the help of the nonprofit, Ride and Drive Clean
