Up to 40% of new street trees die within 3 years — mostly from lack of water.
We've built the fix.
Each lost tree wastes $1,500-$2,000 in planting costs and decades of climate benefits.
Passive Earth creates passive green infrastructure — systems that work with natural processes, without pumps, power, or complex maintenance — to help cities adapt to climate change. Our designs are built to last, cut costs, and fit seamlessly into existing city workflows.
Passive green infrastructure uses gravity, capillarity, and smart design to manage water, support plant life, and deliver environmental benefits without active energy inputs. It's the simplest, most cost-effective way to scale climate solutions in every neighborhood.
We're engineering tools that make climate resilience a built-in feature of urban life. Every product is practical, affordable, and field-proven — because our #1 goal is measurable climate impact at scale.
When solutions save money and simplify the work, adoption happens naturally. That's how we make it possible for cities to meet climate goals faster, with less effort and greater long-term results.
