  • Going ‘Deep Green,' Office Buildings Give Back to the Planet

    More and more commercial real estate projects are popping up around the United States that are focused on “deep green” building. This movement suggests that it’s not enough to just make a building out of renewable materials, but they can also be self-sustaining. For example, the Watershed, an office building in Seattle, has a slanted roof that collects rainwater that is then used in toilets. These types of projects can be more complicated and expensive to build, but developers can save money in the long run with the improvements.

  • Blockchain technology to boost power access in rural areas

    A micro-grid system has been paired with blockchain technology to easily sell and buy affordable and clean energy in rural Kenya. Residents living in the countryside don't generally have access to reliable and affordable electricity but this new technology allows rural Kenyans to install solar panels on their homes and easily sell surplus electricity to neighbors. The pilot program is a result of a collaboration between an NGO and a local tech company.

  • Can direct air capture make a real impact on climate change?

    Climeworks is focusing on pulling carbon dioxide directly out of the air to store or reuse in some capacity as a way to lower global greenhouse gas emissions. The Swiss company has 16 plants around Europe, with their biggest one in Switzerland that removes 900 tons of carbon dioxide a year that is then sold to Coca-Cola Co. to put in soft drinks or to local industrial greenhouses for plant growth. Scaling the operations to capture more carbon is costly, but the startup recently raised $76 million from investors.

  • The young people fighting the worst smog in Europe

    To measure the level of air quality in Skopje – one of the most polluted cities in Europe – an engineering student developed an app that alerts residents of the pollution levels. The app has raised the awareness of the severity of the city's pollution problem and has helped to kickstart initiatives aimed to address it.

  • How ‘Sustainable' Web Design Can Help Fight Climate Change

    As part of a growing movement in sustainable software design, Danny Van Kooten, a Dutch programmer, refactored the code on his website plug-in to reduce the amount of energy expended when someone interacts with it. About 2 million websites use his plug-in and by trimming the code, he estimates that he reduced the world’s monthly carbon dioxide output by 59,000 kilograms. While larger companies like video-streaming services put out more emissions, individual website owners can take steps to reduce their own CO2 footprint.

  • 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.

  • Solar Power Fills Gaps in Underserviced Rural Argentina

    Solar energy has provided an affordable and efficient source of energy to rural farmers in Argentina, who live too far off the electrical grid and have traditionally relied on powerful diesel-fueled water pumps. Solar panels have reduced carbon emissions, eliminated the need for expensive diesel fuel, as well as the hassle of transporting it to the countryside - often over rough roads. The initial investment in solar panels is recouped in a short amount of time and has resulted in a drastic reduction in water consumption.

  • A New Weapon Against Climate Change May Float

    Floating wind turbines off the coast of Portugal is one of the latest experiments to convert wind energy into electric power. These machines can generate electricity for a city of up to 60,000 people. While it will take more financing and time to scale the project, investors are impressed with the results and see it as a viable financial return to combat climate change.

  • #MakeCyclingSafer: In Nairobi and cities around the world Audio icon

    In Nairobi, as in other major cities around the world, the COVID-19 pandemic has shifted travelers away from mass transit to bicycling for social distancing purposes. This presents policy and safety challenges, as many more cyclists use streets designed only for automobiles. But, with benefits extending beyond virus protection to physical fitness and lowering carbon emissions, planners are pushing for cycling lanes and other design changes in hopes that the cycling craze will continue even after the pandemic danger eases.

  • The long road to a zero-carbon country

    The capital city of San José in Costa Rica is taking steps to become greener and less dependent on cars. By focusing on public transportation initiatives like city bikes and bike lanes, a green esplanade, and an electric passenger train, the city is hoping to reduce its greenhouse gas emissions and help the country reach net zero-carbon by 2050. While the cost of these projects can be pricey, many residents are strong advocates for making the city more sustainable.
