About us

Our Mission

Sustainable Practices is a Barnstable County focused environmental action group. We work across all 15 towns in Barnstable County to facilitate a network to support environmental quality for our residents, visitors and fundamentally, the ecosystem on which we are dependent and of which we are all a part.

The overarching mission of Sustainable Practices is to facilitate a culture of sustainability as defined by reducing the human-made impact to the planet and its ecosystems. The organization seeks to achieve its goal through the promotion of a global environment that supports the value of all life. To this end we specialize in the integration of sustainability into business, non-profit, and government operations, curriculum and stakeholder communications:

  • Create sustainability-focused communications and marketing communications targeted to both financial and operational sustainability: process mapping, stakeholder communications and targeting, risk management, sustainability action plans, and corporate social responsibility.
  • Develop curriculum to teach and incorporate sustainability into an operating structure: general curriculum (i.e. company-wide, school system-wide), economics curriculum (i.e. university economics curriculum, including online platforms); non-profit and government operations (e.g. development of comprehensive operationalized sustainability programs and strategy initiatives focused on resident and visitor environmental sustainability education).

Sustainable Practices Ltd. is a non-profit, IRS 501(c)3 designated corporation.

Our Community Engagement

Recent Press

Our Cape Plastic Bottle Ban initiative has commenced and is presently filed or in process in 9 of the 15 towns that comprise Barnstable County. The municipal by-law will be on local town meeting warrants in spring 2019 for towns where it has been filed by Citizen's Petition and will be both an educational campaign on the adverse impact of human convenience and a first step toward reduction of plastic use on the Cape. Our educational campaign will focus on the true cost of convenience consumption and is part of our long-term focus. 

The Sustainable Practices initiatives were the subject of the December issue of edible Cape Cod magazine. This article along with recent news coverage highlighting our Cape activities on a town basis can be found on Our News page. 

Our Activities

As a community-based organization on Cape Cod, we are helping to make this beautiful locale a better place to live. With the help of volunteers, we organize community-building and educational events on the values and benefits of conscious consumption for long-term sustainability.

We are currently engaged in three community initiatives:

As part of our routine civic engagement we maintain two Adopt-A-Highway sites and one Adopt-A-Visibility site on highway 6 on Cape Cod. Our areas are cleared of and patrolled for debris by volunteers on a monthly basis. They are located between exits 10 and 12 on both the eastbound and westbound lanes of the highway. 

Our Initiatives

Cape Plastic Bottle Ban


The Cape Plastic Bottle Ban is an educational and citizen advocacy program to raise awareness of the environmental and human impact of plastic bottle consumption. We are currently focused on eliminating plastic bottle purchase, sale, and distribution by town, regional, and county government on Cape Cod.

Details on the Bottle Ban effort, including upcoming activities can be found on the Bottle Ban page.

Sustainable Practices Sustainability Film Series


Along with our sponsor, the Chatham  Orpheum, our movie series promotes awareness and understanding of the role of consumption choices on the health and well-being of both humans and the environment. Our next film at the Orpheum will be Sacred Cod. Listings of our movies for spring 2019 can be accessed on our Film Series page.

Sustainable Practices Film Contest


The Sustainable Practices Film Contest is open to all non-professional film makers who are residents of Barnstable County, Massachusetts. The contest is specific to short educational films with a sustainability theme.
