Ivan Frishberg | Collaborating to manage and finance the climate transition
Every day, the alphabet soup of climate and ESG-related NGOs seems to thicken. But their respective raisons d’etre can seem like a mystery for all but the closet of insiders. To help unravel the role of each of these organizations in the broader social movement and policy push for urgent climate action, Chad Reed speaks with Ivan Frishberg, the chief sustainability officer of Amalgamated Bank and a pioneer of climate collaboration for big banks and corporates. Given his historically central and successful role in driving industry collaboration on climate action, Ivan provides key insights into the current state of this evolving landscape, delves into the hot topic of divestment versus engagement, and discusses the merits and significance—or lack thereof—of the so-called ESG backlash.

The secret life of corals | Dr. David E. Vaughan
Corals are the gems of the oceans, creating beautiful colors and shapes that form our reefs while serving many vital functions for life on this planet. With 25-40% already lost, the worldwide coral population faces incredible danger from climate change and other threats. But there is hope. On this week’s episode, Hilary and I talk with Dr. David E. Vaughan, an esteemed marine biologist and author of the new book The Secret Life of Corals: Sex, War, and Rocks that Don’t Roll.Dr. Vaughan has held aquaculture research and development positions for over 45 years. He is best known for developing the innovative restoration technique of “micro-fragmentation, which can speed up coral growth by 25 times by breaking them into tiny little pieces. He is focused on making this innovative process a scalable tool for reef restoration as the Founder of Plant a Million Corals. As you’ll hear in this conversation, David brings great clarity and joy when talking about corals and why they are so important.Links:Book: The Secret Life of Corals: Sex, War and Rocks That Don't RollWebsite: Plant A Million CoralsDr. David E.

Carbon accounting 2.0 | Toby Ferenczi and Killian Daly, EnergyTag.
As more and more leading companies, governments, and other large buyers of electricity pledge to procure 100% carbon-free energy (CFE), markets are in need of better, more granular information on the time, location, and emissionality of every megawatt-hour that is produced and consumed. To this end, EnergyTag – an independent, non-profit, industry-led initiative – is developing the standards and markets for Granular Certificates (GCs) that enable energy consumers to verify the source of their electricity and carbon emissions in real time. In this episode, Chad Reed sits down with Toby Ferenczi and Killian Daly, the Founder and General Manager, respectively, of EnergyTag. They discuss the cruel irony at the center of deploying more and more renewable energy on local grids, the nuances differentiating 24/7 carbon-free electricity claims from emissionality considerations, and how Granular Certificates can both drive the next generation of carbon accounting (or Carbon Accounting 2.0) as well as accelerate the growth of new markets such as green hydrogen and battery storage.

Unpacking West Virginia v. EPA | Max Rodriguez
Earlier this year, the U.S. Supreme Court in West Virginia v. EPA ruled that the Clean Air Act does not authorize the EPA to require a systematic shift to cleaner sources of electricity generation. Many fear this decision will be devastating to the agency’s and the executive branch’s ability to move the U.S. away from carbon-intensive energy sources and toward cleaner resources to address climate change in the accelerated timeline necessary to avoid its worst impacts. So, in this episode, Chad Reed sits down with Max Rodriguez, an attorney with Pollock Cohen and the primary author of an amicus curiae brief on behalf of 192 Members of Congress supporting the EPA’s authority to regulate carbon emissions under the Clean Air Act. Max discusses in depth the history and justiciability of the case, the major questions doctrine underpinning it, the potentially far-reaching implications of the decision and the related non-delegation doctrine for federal environmental regulations going forward, and much more.Importantly, the Inflation Reduction Act, which passed after this episode was recorded, amends the Clean Air Act to add several specific new programs to reduce greenhouse gas emissions and provide funding to the states to develop their own plans. Taken together, these provisions go a long way towards addressing the view of the 6-3 majority in West Virginia v. EPA that Congress has not been clear enough regarding the EPA’s authority to tackle climate change. However, the new law may still fall short of granting EPA the authority to revive the generation-shifting approach struck down by the Court in this case. Links:West Virginia v.

Our fusion powered future | Jim McNiel, TAE Technologies
For decades, many have called nuclear fusion the “holy grail” of energy sources. The undying hope is that fusion will someday provide very cheap, abundant, zero-carbon electricity to all – thereby both decisively addressing the climate crisis and powering economic growth across the globe. But despite decades of well-funded research and even recent technological breakthroughs, we still seem to be years away from a commercially viable fusion reactor. In this episode, Chad Reed speaks with Jim McNiel, Chief Marketing Officer of TAE Technologies, which just raised $250 million in venture financing to support the development of Copernicus – its next-generation hydrogen-boron fusion research reactor. Chad and Jim get into the weeds on the tradeoffs of competing fusion fuels, the longstanding challenge fusion must overcome to reach commercial viability, the role of fusion in our energy future, Star Trek versus Star Wars, and much more.Links:Article: TAE Technologies Exceeds Fusion Reactor Performance Goals By 250% As Company Closes $250 Million Financing Round, Totaling $1.2 Billion To Date (July 2022)Article: Nuclear-fusion reactor smashes energy record (Nature, February 2, 2022)Article: ITER fusion project preparing to outline revised timetable (World Nuclear News, July 11, 2022)Episode recorded: July 28, 2022Email your feedback to Chad, Gil, and Hilary at climatepositive@hannonarmstrong.com or tweet them to @ClimatePosiPod.
