Why Monthly Giving Changes Everything
For 55 years, Acterra has been driving climate solutions in our community. But here's what keeps us up at night: most environmental funding is unpredictable. Grants end. One-time donations fluctuate. Meanwhile, climate change doesn't take breaks.
Monthly giving changes the game. When you commit to a recurring gift -whether it's $5 or $500 - you give us the stability to plan bolder, act faster, and create lasting change. You become part of a community that's not just reacting to the climate crisis, but proactively building solutions.
The Climate Action Circle is for everyone. You don't need to be wealthy to make a real difference. When 1,500 of us give an average of $25/month, we generate $450,000 annually - enough to transform what's possible.

Monthly gifts provide predictable, year-round funding that lets us plan strategically and act boldly on climate. Instead of scrambling for grants or waiting for end-of-year donations, we can hire staff, launch programs, and commit to multi-year initiatives with confidence. Your $25/month has far more impact than a $300 one-time gift because it signals long-term partnership.
