We design ambitious strategies and solutions that rise to meet the challenge of climate change at the necessary scale


We collaborate at every stage, because our work must be both inclusive and iterative if we are to have climate impact


We act to prevent suffering, enable resilience, and protect nature for planet and prosperity

VOX—TerraPraxis has been listed among seven of the most high-impact, cost-effective, evidence-based organizations fighting climate change. Why Johannes Ackva and Luisa Sandkühler of Founders Pledge recommend TerraPraxis: “We believe that TerraPraxis continues to do incredibly important work around shaping a conversation for advanced nuclear to address critical decarbonization challenges, such as the decarbonization of hard-to-decarbonize sectors and the conundrum of how to deal with lots of very new coal plants that are unlikely to be prematurely retired.”

EVALUATE App Launch at COP27

"What I love about what you’re doing is that you’re taking the opportunity to look at these coal plants, and not just close them down, but turn them into something new and better,” Microsoft President and Vice Chair, Brad Smith, said at the launch of our new EVALUATE application, enabling every coal plant owner in the world to assess their coal plant for conversion to clean energy. Watch the video to find out more about how we are moving from pledges to progress with our partners at Microsoft and Schneider Electric.

Planetary Stewardship at Tedx Boston

TerraPraxis participated in the inaugural Planetary Stewardship Event that elevated transformative ideas on climate and established Boston as a hub for driving powerful ideas toward global climate and sustainability solutions, where our Chief Development Officer, Megan Pulliam, presented the TerraPraxis REPOWER initiative.

In this talk, Megan shared how repowering the world's 2,400 coal-fired power plants (2TWe) with advanced fission or fusion emission-free heat sources by 2050 is the single largest carbon reduction opportunity on the planet.

Repowering Coal

This ambitious project will design a process to repower the world's coal fleets via a fast, repeatable system resulting in carbon negative power plants that are cheaper to operate than before and ensure continuity for communities reliant on these plants for energy and jobs.

Our report reveals how untapped options for clean hydrogen can put the world back on the pathway to the Paris climate goals​—if sufficient, low-cost, clean hydrogen is produced to replace oil and gas in shipping, aviation and industry. The amount of hydrogen required is far more than can be produced with renewables alone, but anew generation of advanced modular reactors could produce enough climate-neutral fuel to displace the 100 million barrels of oil that are currently consumed around the world each day.

Beautiful Nuclear

This report by LucidCatalyst shows how nuclear energy helps meet all 17 of the United Nations Sustainable Development Goals. No other electricity generation technology can match this diversity of beneficial impacts. The report argues that the priority for preventing irreversible climate change is decarbonisation, not the creation of energy systems which are 100% dependent on renewables. It is critical to take a whole system approach to the energy transition and for evidence-based decision making. In the context of the increasing urgency to replace fossil fuels, the range of low carbon options must include nuclear.
