What is Sostane?

Sostane (Sisters of Sustainability) provides a nurturing environment for local green women to take action in sustainable practices. Through local meetings, festival participation, member-written articles and online resources, we are inspired to take that extra step to make a difference to our community.

We are individuals, independent business owners, mothers, daughters, wives and sisters. We are concerned at the state of our planet not only for ourselves, but for our future generations. Our responsibility reaches farther than sustaining or maintaining at our current levels, but going above and beyond by giving back to the earth in a cradle-to-cradle mentality.

We are committed to the betterment of the environment, social justice, local economy and ourselves.

A letter from the founder

Dear Green Sister,


I am like you.

I have been so lucky and fortunate to find like-minded individuals through my business, Beneficial Design, which focuses on green marketing materials for women entrepreneurs. I have had so many conversations with all of you about how we really are trying our best to be more sustainable. I have enjoyed our discussions, but yearned for get everyone together to talk about it.


We need to work together.

As women, we are naturally and instinctively nurturing. We take care of our children, our families and now we must take care of the earth. Through our businesses and livelihoods, we have so much more influence than we realize and communicating with each other is only going to make it stronger.


We need you.

It's not about doing a little here and there. We are already doing that. It's about rethinking all of our processes, practices and techniques. Not to maintain, but to give back to the environment what we have already taken. Walls and beliefs will need to be torn down to find the solutions we are all looking for. They are there— simply, creatively and completely. Together, we can pledge the responsibility our planet is asking for.

This is just the beginning. Now we need your help.

Join us in our gatherings, our network, and our online discussions as we talk about how we can run our businesses and our lives more sustainably.
