Gardeners transform food waste into fuel, aiding the climate

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.

After realizing the rate that which food gets thrown away at grocery stores due to approaching expiration dates, one man in Nigeria decided to do something about it. Oscar Ekponimo created a web-based app that lets grocery store retailers know if something is near expiration. Once notified, the retailers mark down the item; this allows non-governmental organizations to purchase and sell to people that are food insecure.

Bruce Friedrich, the Executive Director of The Good Food Institute in Washington, DC, thinks that we're wasting resources raising animals for food products. He thinks the answer is creating a product that doesn't replace meat, but rather competes with it.

Billions of people around the world lack access to safe sanitation, causing disease and deaths. In Ecuador a foundation developed a cheap, dry, composting toilet for poor rural families.

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.

Scientists are testing if adding alkaline substances to seawater can allow oceans to absorb more carbon dioxide emissions. Early tests suggest this could be a potential way to combat climate change, but there are still many questions about how this can scale, how it impacts the natural ecosystem, and if it’s cost effective to implement.

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.

Solar-powered cold storage units help farmers in India to store their harvests during extreme heat instead of discarding their produce or trying to sell it quickly for cheap to avoid waste. The solar-powered option is significantly cheaper than typical electric cold storage, making it more accessible to small-scale farmers.

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.
