We continue our Summer Playlist this week by welcoming Catherine Flax back into the SmarterMarkets™ studio. Catherine is CEO at Zefiro Methane Corp. David Greely sits down with Catherine to catch up on her work at Zefiro addressing the global methane emissions problem by cleaning up and plugging end-of-life oil and natural gas wells. David and Catherine also discuss how she's been navigating the reduction in carbon finance through the voluntary carbon markets and the volatile policy landscape in the United States to better understand what it takes to run a company in a challenging environment.
