Early in the morning on June 5, 2001, the tents in which Dakota Stormer and his family were sleeping started to blow over. Rain started coming down, hard and sideways, as the family scrambled to escape tropical storm Allison, which would later devastate the Houston area with flooding and kill 41 people. Stormer and his family made it home safely, but there were damages: $8.5 billion across the Atlantic coast, and a severe impression on Stormer that environmental issues were of deadly consequence.

Last year, Stormer's interest in environmental activism led him to make Footprint, an app that tracks the carbon footprints of users. It works similar to diet-tracking apps like MyFitnessPal, but it doesn't count the calories; instead, it logs the emissions of their eating and travel habits.

"It's kind of difficult to change your behavior immediately, but we try to make it easy so that your sustainable decisions can become a habit," Stormer says.

Climate change threatens the Houston area remarkably: Rising sea levels and warming waters will likely bring stronger and more devastating storms to the city — not unlike Hurricane Harvey, a category 4, which hit in 2017.

In 2018, Stormer joined the Citizens Climate Lobby to push legislation that could combat the effects of climate change in Texas. The Lobby appeals to both sides of the aisle, Stormer says, but getting laws passed still takes time — and many of the lobbyists wanted a way to engage themselves in the environmental efforts at a human level. That's how Stormer, along with three high school students as interns, came up with the prototype for Footprint.

Footprint users complete generalized surveys that sum up the carbon emissions of their day-to-day habits — how often they drive and fly, their meat intake and typical portion sizes. The app's algorithm calculates an annual carbon footprint, then averages it out to a per-week measure. This way, users know their goals — and the app sends them suggestions and challenges, like "meatless Mondays," to help reduce their emissions. This feature, Stormer says, can be used in organizations to create competitions that incentivize reducing everyone's carbon footprints.

"For one person, it doesn't seem like there's much that you can do," Stormer says. "But the number of people across the world that care about climate change — it's actually a majority, at this point."

There's also a marketplace, which connects Footprint users to other companies creating sustainable products and organizations that offer environmental resources. The major thrust, though, of this early-stage project is education: Footprint is piloting in a Houston classroom, and Stormer has plans for more pilots across Texas to affect more environmentally conscious curriculum. Having recently graduated high schoolers on the staff, Stormer says, has helped to easily fit the app into classroom settings. They're also running a pilot in a local law firm, to test the app's effectiveness in corporate settings.

For now, Footprint is raising $65,000 in an angel round to run effectively and hiring another developer to monitor the app as it grows past its early stages. It has also recently formed a climate advisory council — made up of researchers, professors, investors, principals, and other education professionals — to engage even more people in the app's development.

Stormer's strategy is to create a community of people invested — financially, politically, and personally — in reducing human impact on the earth.

"When you build a community around it, you can have significant impacts on the future of our planet," Stormer says.
