Too Good to Go

Austria rolled out the KlimaTicket, an annual pass that gives the holder access to all forms of public transportation in the country, to encourage increased use of public transport with an eye toward climate change mitigation. The uptake has exceeded expectations with 134,000 tickets sold within just the first two months, but it's still unclear what effect the program will have on the country's carbon emissions.

To address the food insecurity problem among its low-income students, Columbia University launched Swipes, a meal sharing app in which students with a surplus of “meal swipes” could donate them to students in need. But when that app struggled to function and roll out properly, Columbia looked downtown to New York University, where student Jon Chin launched a similarly purposed but more effectively designed app, Share Meals. So far, the app has enabled over a thousand meal donations, and is hoping to work with Columbia to share its code and expand its donor services.

Though homelessness is an entrenched and complex problem, small solutions can make a difference in the daily life of homeless individuals. Lockers for overnight cell phone storage in a homeless shelter in Chicago are significant: people can wake up with a sense of security, knowing their phones will be available to help find jobs or stay in touch with loved ones. This is part of the Chicago Youth Storage Initiative, which as since funded 755 storage unites at homeless shelters across Chicago.

Crime-tracking mobile apps give millions of Brazilians crowdsourced data on urban violence, alerting people to dangerous places and filling gaps in government data on shootings, robberies, and other risks. But apps such as Fogo Cruzado (“Crossfire”) and Onde Tem Tiroteio (“Where There's a Shooting”) offer statistically crude glimpses of crime, distorted by media and racial biases that one expert blames for myths about the risks people actually face.

An initiative on the Moscow metro system has posters on the train featuring cats and dogs that are looking for a home. Known as the “Tails and Paws” train, these animals come from 13 animal shelters in the city and riders can use their phone to scan the poster to learn more about the animals up for adoption. “It’s about forming a new culture of responsible attitude to animals,” says one of the workers at a shelter.

A community organization in Indiana called Cultivate "rescues" food from local caterers, hospitals, casinos, and businesses to then be packaged into take-home meals for students at Woodland Elementary School that come from food-insecure homes. Cultivate is in its second year of existence, has three staff and 400 volunteers, and hopes to expand beyond their pilot program to reach all 21 schools in the district.

After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.

Two insurance companies, Discovery and Dialdirect, implemented a smartphone app for drivers to report potholes in their city. The companies then fill the potholes and brand them with their logos.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.

New Jersey schools are working to make climate education widespread by implementing general education standards that include climate change education in every grade and subject. These new education standards have been inspiring students to brainstorm solutions to climate-related issues like reducing food waste and increasing coastal resiliency. The state has also earmarked $5 million to help local teachers attend professional development sessions to teach them how to create new climate change-focused lesson plans.
