    Why all ride-sharing should go electric. And autonomous, with Dave Rubin

    Why all ride-sharing should go electric. And autonomous, with Dave Rubin

    Ride-sharing services currently result in 69% more emissions, on average, than the trips they displace, according to a recent study by the Union of Concerned Scientists.

    But, if the ride-sharing vehicles were electric, it's a whole different story. Replacing one gasoline-powered ride-sharing car with an electric vehicle (EV) has three times the climate benefit as replacing a personal car with an EV.

    Some companies like Cruise and Aurora go even further, developing electric autonomous fleets, which could further reduce the carbon footprint of ride-share vehicles.

    Climate Now spoke with Dave Rubin, Head of Policy Research at Cruise, a self-driving, ride-sharing service, to understand how electric and autonomous vehicles could help us decarbonize road transportation, and the challenges ahead for wide-scale adoption.

    Green banks: How they unlock funding for climate solutions, with Bryan Garcia

    Green banks: How they unlock funding for climate solutions, with Bryan Garcia

    The Connecticut Green Bank, the first green bank in the US, has unlocked over $2 billion in capital toward clean energy projects and other climate solutions since it was established by the state legislature in 2011.
    So, what is the green bank model? How does it compare to other methods of clean energy finance? And what are their impact?
    Climate Now speaks with Connecticut Green Bank President and CEO Bryan Garcia to find out.

    Ocean-Based Carbon Dioxide Removal and Geoengineering, with Wil Burns

    Ocean-Based Carbon Dioxide Removal and Geoengineering, with Wil Burns

    Earth's oceans play a key role in slowing climate change, absorbing nearly a third of anthropogenic CO2 emissions.

    And they could, potentially, absorb more.

    In this episode, Climate Now explores developing methods to enhance ocean-based carbon dioxide removal. What do we know about each technique, and what are the associated risks?

    Learn more in our conversation with Dr. Wil Burns, visiting professor at Northwestern University's Environmental Policy and Culture Program and emeritus co-founding director of the Institute for Carbon Removal Law and Policy at American University.

    Unpacking COP 26: Are we on track to solve the climate crisis, with Megan Darby

    Unpacking COP 26: Are we on track to solve the climate crisis, with Megan Darby

    In November 2021, representatives from around the world gathered to update their climate commitments at the 26th United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP 26) in Glasgow, Scotland.

    The conference received substantial attention from media and climate groups around the globe, the likes of which we haven't seen since COP 21 - the 2015 Paris Climate Accords.

    So why was there so much anticipation leading up to this year's COP? What were the expectations, and were they met? And do the new commitments made at COP 26 put us on track to meet global climate targets?

    Megan Darby, Editor of Climate Home News, a UK-based news organization that covers the international politics of the climate crisis, joined Climate Now to unpack the key results from COP 26.

    Scaling wind energy: What it will take to reach global net-zero, with Simon Watson

    Scaling wind energy: What it will take to reach global net-zero, with Simon Watson

    Wind energy is one of the cheapest sources of energy today, but it accounts for only ~6% of global electricity generation.

    To limit global warming to 2 degrees C or less, wind energy will need to scale up to about 5 times its current size. | 

    So, how can this be achieved? What are the challenges to scaling wind energy to this degree? How does off-shore wind fit into this equation? And what needs to happen this decade to put us on track?

    Climate Now is joined by Dr. Simon Watson, Director of the Delft University of Technology Wind Energy Institute, to discuss the role of wind energy in the transition to a low-carbon economy.
