  • Energiesprong wants every home to be net-zero

    Inspired by the Dutch concept of “Energiesprong,” or “energy jump,” a developer in France retrofitted a group of townhouses for social housing to be more environmentally friendly. They installed polyurethane facades to avoid heat loss and solar panels on the roof. Upgrading the units to be more green cost more than a conventional retrofit, but over time, energy bills were cut in half. These green retrofits are being implemented in towns around the world and could be a model for developers that want to reduce their carbon footprints.

  • ‘Within minutes I was weeping': the US pastor using scripture to mobilize climate action

    Rev. Scott Hardin-Nieri of North Carolina works with the Creation Care Alliance to better connect his Christian faith with climate action. Over the years they have developed a toolkit for congregations on how to get involved in the climate discussion. They also host eco-grief meetings that are very popular. They would like to reach more conservative or evangelical members of their community that are more skeptical of climate change, but they have had some success in reaching a wide audience.

  • The fight to save India's most elusive cat

    After a fishing cat was first documented in an Indian coastal city, state authorities, scientists, and conservationists sought to understand how many felines called the wetland home. Using camera traps, they observed 10 individual fishing cats among the mangrove forests, though this method of estimating the population is tricky. Another survey is underway as researchers study how the health of these habitats are linked to the health of the fishing cats, and how to effectively educate locals about the importance of protecting this species.

  • Is Seaweed The Key To Carbon Offsets?

    Running Tide Technologies, a shellfish hatchery in Maine, is betting on kelp forests as a way to store carbon deep in the ocean and sell that carbon to corporations looking to combat climate change and offset their own emissions. The startup is growing mini-farms of kelp on biodegradable floats and after a few months, they sink to the seafloor. More research is needed to see if it works, but they already have about 1,600 floats adrift in the ocean and the e-commerce company Shopify is the first to buy carbon offsets from them.

  • The Southwest Offers Blueprints for the Future of Wastewater Reuse

    As the U.S. Southwest continues to navigate ongoing water crises, several places — including Las Vegas; Orange County, California;, and San Diego — are turning wastewater into drinking water. Their various systems are recycling and treating wastewater as a way to save money and create a reliable supply of drinking water for residents in arid climates. Outreach and education in these communities helped make these systems successful and could be a model for others looking to supplement their traditional water supplies.

  • How Scientists Are Pivoting In Their Quest To Save Hawaii's Crows

    After a five-year effort to reintroduce the alala bird on Hawaii’s Big Island failed, conservationists are looking into releasing the nearly extinct Hawaiian crow on a different island. Of the 30 birds released in 2016, only five survived. Another predator known as the Hawaiian hawk killed off some of the birds. Releasing the crows on Maui is a temporary solution, but could allow them to learn skills to survive with other predators.

  • With phones and seeds, jobless Kenyans tackle illegal logging

    As a way to combat unemployment due to the COVID-19 pandemic and to prevent further deforestation in Kenya, local rangers are using smartphones, satellite feeds, and global mapping to monitor their forests. The project employs more than 250 people and allows them to target vulnerable areas more effectively. Because of their efforts, there have been lower incidences of illegal logging and forest fires from poachers.

  • The Mexican women who kicked out the cartels

    Ten years after the women of Cherán, an indigenous town in Michoacán, took up arms to lead an uprising against criminal cartels, their town is an "oasis" of low crime in a region otherwise beset with violence. The town declared itself autonomous and women now belong to the community police force that patrols the town and its surroundings. The cartels' illegal logging and extortion of businesses had corrupted local politicians and threatened a way of life. The town's men did nothing about it, so the women led the uprising that established order and kept the crime at bay.

  • Vanuatu looks to local food production for a resilient future

    As the small island nation of Vanuatu emerges from the COVID-19 pandemic and the aftermath of a tropical cyclone, entrepreneur Votausi Lucyann Mackenzie-Reur argues that they need to focus on local ingredients to be able to respond to future crises. Oxfam is also doing work in this region by using blockchain technology to improve food purchasing power for people affected by disasters. “Food security, climate change, and biodiversity can all be tackled by promoting and advocating the use of local traditional foods,” says Mackenzie-Reur.
