Thank you to Fred for reviewing my solar panel quotes and for helping me understand what it all meant. He put all the data in a chart so they could be compared against each other. He gave me suggestions and questions to ask that would be important to know before deciding what was the best choice. His input and knowledge helped me greatly when it was time to choose a company for my solar needs. His independent review was exactly what I needed. —Meredith Herzog

Our Mission

Our mission is to help environmental champions create superbly sustainable homes and organizations.

Environmental Champions

You are an environmental champion if you care about our environment and take effective action to protect it.

Best Practices for Sustainability

Best practices are actions you can take to meet your needs in ways that protect the ability of future generations to meet their needs, too.

Sustainability Plans

Your sustainability plans reflect your values and priorities. We help you create sustainability plans for your own home and organizations, and achieve the goals in your plans.

About Sustainable Practice

Fred Horch is the principal advisor here at Sustainable Practice. Fred's sustainability writing and advice draws on his experience as a small business owner, author, Rotarian, Master Gardener Volunteer, former lawyer, active citizen, husband and dad living in Brunswick, Maine. After a brief career as a corporate attorney, he has had the privilege to work full-time for sustainability since the 1990s. Fred has started his own businesses, had leadership roles in non-profit and political organizations, and (with his wife Hadley) raised three kids, so he understands the challenges you face if you're running a business, leading a team, or managing a household.
