  • Philanthropies flow funds to climate technologies

    Philanthropies are funding “tough tech” startups that are developing technologies to cut greenhouse gas emissions and mitigate the effects of climate change. Since 2014, the nonprofit Prime Coalition has channeled more than $24 million from wealthy donors and foundations to 10 ventures focused on that goal. Not all of their investments, though, have paid off. Yet, some of these initial investments could lead to widespread solutions to the world’s climate crisis.

  • How a #Litterati army on Instagram sparked a global fight against litter

    What started as a small group of people taking pictures of waste in their communities and tagging it on Instagram with the hashtag #Litterati, turned into a global effort, and even an app, to map and dispose of trash. Users can upload to the app an image of trash and machine-learning algorithm can tag it location, material, and company who made it. The city of San Francisco asked the makers of the app for help documenting cigarette butts and tobacco products on its streets and ended up winning a legal victory over the tobacco industry to increase the taxes on their products.

  • Smart Tourism

    Tourists can travel to remote destinations in the Himalayas and help install solar technology in villages where residents live without electricity. GHE has used funds from the tourism component to electrify 100 villages which increased the quality of life for residents and resulted in an opportunity for tourism where one did not exist before. As a result of the electrification, a community tourism initiative allowed for tourists to stay with villagers and provided an addition source of income. The economic stimulus from tourism gave native youth a reason to stay in their villages instead of migrating.

  • Locals Question the Relevance of First Solar Power Plant in Soroti

    Four years later after a solar grid was installed in Uganda, residents of nearby villages are wondering when they will get some of that power. The 10-megawatt facility, which cost $19 million to build, was expected to provide electricity to about 40,000 homes, schools, and businesses in the area. However, almost all households in the 10 surrounding villages still use firewood for cooking. The lessons learned from this renewable energy project could help inform others as the country looks to power more parts of the country with solar panels.

  • The Sudbury model: How one of the world's major polluters went green

    After being known as a polluted mining town, politicians, scientists, industry officials, and residents of Sudbury, Ontario, were able to come together to restore its land. After 40 years and $33.5 million, they are about halfway through recovering about 200,000 acres of land. So far, they’ve been successful at restoring air quality, neutralizing soil to allow for replanting, and restocking lakes with fish. While some locals think the mining companies should have done more, the collaborative spirit could be a model for other communities looking to improve the environment.

  • Would You Eat Food Waste To Help Tackle The Climate Crisis? These Companies Are Betting On It.

    Companies around the world are investing in “food upcycling,” which involves turning food waste that would usually end up in a landfill into new edible products. In 2019, member companies of the Upcycled Food Association — which includes pet food, juice, and snack brands — helped prevent 8 million pounds of food waste. Though scaling these operations can be difficult, the food upcycling sector was worth $46.7 billion in 2019 and is expected to grow.

  • Investors Want to Align Their Dollars with Racial Justice Demands

    Investors are using their clout to call for racial justice through the investment consulting firm Activest. The firm is attracting millions of dollars from companies that want to make fiscal justice investments. In a bid to use investments to fuel the grassroots criminal justice movement, Activest is alerting municipal bond investors when the city of Chicago uses those bonds for police brutality settlements. Activest has lined up $100 million from investors who want to make fiscal justice investments through municipal bonds which would then allow them to have a say over how it is, or is not, spent.

  • Bitcoin Miner Is Scoring 700% Profits Selling Energy to Grid

    A cryptocurrency mining company in Texas called Layer1 can power down its data-processing centers and sell its unused electricity back to the power grid. Instead of passively consuming energy, they are able to utilize batteries, smart meters, and artificial intelligence software to use more renewable energy and, at the same time, make a profit. While scaling this response can be difficult due to restrictions from utility companies on how consumers get their energy, Layer1 estimates it will save up to $6.7 million annually by cutting production for 30 minutes during some of the hottest days in the summer.

Despite this increase in interest, shareholders continue to grapple with balancing sustainable considerations with investment decisions.

  • Could carbon-removal tech make travel more sustainable?

    Climeworks, a Swiss start-up, is using technology to suck carbon out of the air and turning it into stone, essentially cutting greenhouse gas emissions from the atmosphere permanently. Their plant in Iceland is able to turn 50 tonnes of carbon to stone per year. While that amount of carbon won’t solve the climate crisis, they are expanding their work to other countries and are launching a personal carbon removal subscription service as a way for the travel industry to help offset the carbon that they emit each year.
