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:


  • Increase awareness of the health and environmental impact of consumption and foster conscious consumerism through enhancing individual accounting of the lifecycle impact of consumption choices, including introduction of regulatory initiatives.



  • 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

The Cape Plastic Bottle Ban is an educational and citizen advocacy initiative focused on raising awareness of the environmental and human impact of single-use plastic bottle consumption. In 2019, we initiated the Municipal Plastic Bottle Ban, which focused on eliminating non-emergency single-use plastic bottle purchase by town governments and sale of beverages in single-use plastic containers on town property across all towns in Barnstable County, Cape Cod. As of year-end 2019, the Municipal Plastic Bottle Ban was adopted by 11 of the 15 towns that comprise Barnstable County. In 2020, we will launch the Commercial Single-use Plastic Water Bottle Ban (Commercial Ban) across all 15 towns. The Commercial Ban will eliminate the sale of non-carbonated, non-flavored water in single-use plastic bottles of less than one gallon in size within the jurisdictional area of a town.

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 two ongoing community initiatives:


As part of our routine civic engagement we maintain three 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 between April and November. They are located between exits 10 and 12 on both the eastbound and westbound lanes of the highway and include the Eastham Rotary, where highway 6A and 6 merge.
