  • Turning manure into money

    Dairy farmers in Massachusetts are working with Vanguard Renewables, a food waste energy company, and Dominion Energy, an electric utility company, to capture manure methane gas from cows and convert it into natural gas. They are also adding food waste to the manure from manufacturers and retailers to increase energy output and increase income for farmers. The partnership has expanded to dairy farms in other states who are looking to lower their greenhouse gas emissions.

  • 'Cool pavement' experiments help urban planners find ways to ease rising temperatures

    To combat the effects of rising temperatures due to climate change, Los Angeles piloted an experiment called “cool pavements,” where they coat streets with a light-colored sealant to reflect heat. Researchers are studying how effective this method is at reducing the urban heat island effect. Using a mobile sensor station, they found mixed results: While the surface temperature of the road was cooler, a person could feel warmer on the reflective roads. Figuring out how to balance different heat-mitigating strategies could be helpful as cities like Phoenix figure out how to implement cooling infrastructure.

  • The best trees to reduce air pollution

    New technology is helping urban planners and developers better identify which trees could help cities reduce air pollution. In Ontario, the city of Oakville adopted a new software that resulted in planners halting the planting of one type of tree after learning it had little benefit on the air quality, while another digital tool designed in London is helping citizens determine which plants help remove particulate matter.

  • The Business of Burps: Scientists Smell Profit in Cow Emissions

    A company called Mootral is studying whether changing a cattle’s diet could make the animals belch and flatulate less methane. They created a food supplement out of compounds from garlic, citrus, and other additives, that in early tests, has shown a decrease in a cow’s emission of the greenhouse gas. If they can get investors on board and scale it to different breeds of cows and in different climates, it could help the agricultural and farming industries to combat climate change.

  • London's Trees Are Saving the City Billions

    A recent study on London's trees revealed benefits far beyond city beautification. The report found that trees saved the city billions of pounds in air cooling, air purification, carbon sequestration. The report also found trees brought workers increased productivity.

  • Energy efficient homes mean less air pollution. But are they affordable?

    To reduce greenhouse gas emissions that contribute to climate change and air pollution, Habitat for Humanity Salt Lake Valley is building airtight homes that will also reduce energy costs and be affordable for people experiencing economic hardship. The home are largely being built by volunteers, so the process has been slow and there have been mistakes in building the homes. However, the homes are estimated to reduce carbon dioxide emissions by 4.9 tons a year.

  • Phoenix replacing diesel-fueled garbage trucks with natural gas ones

    Arizona has the second most-polluted air of any state in America, but local government leaders are championing the Cleaner Trucks Initiative as one tool to improve air quality. The city of Phoenix received $1 million from the EPA to transition garbage trucks from diesel to compressed natural gas to reduce emissions and pollution.

  • 'Scary Moms' Are Part Of The Citizen War Against Pollution In Pakistan

    In cities across Pakistan, smog and air pollution are dire health threats but the country's government hasn't done enough to take it seriously - so citizens are pushing back. Initiatives to crowd source air quality data and a push from local mothers to encourage parents to use school buses for their children to lower transportation emission is raising awareness and producing results.

  • This dark material: the black alchemy that can arrest carbon emissions

    Biochar is a form of charcoal that is proving to be quite useful in terms of renewable energy and combatting the climate crisis. From trapping carbon and methane emissions to playing a role in heating homes and feeding cows, some estimates are already showing that biochar has the potential to "offset 1bn tonnes of carbon a year."

  • Pollution Solutions

    The Central Valley of California has an air pollution problem, so community groups are joining forces under the Central Valley Air Quality Coalition to work together towards change. Although progress is slow, the group has been able to teach citizen science in order to collect data as well as advocate for and get a state policy in place that "directs support and resources to environmentally and economically distressed California communities."
