Efforts to hold major greenhouse gas emitters accountable for the harms caused by global climate change have been consistently frustrated at the procedural stages of litigation in U.S. federal courts. This Article explores using a combination of class action mechanisms to engage with these threshold barriers and hold carbon-major corporations responsible for climate impacts.

The Paris Agreement’s goal to hold warming to 1.5°-2°C above pre-industrial levels now appears unrealistic. Profs. Robin Kundis Craig and J.B. Ruhl have recently argued that because a 4°C world may be likely, we must recognize the disruptive consequences of such a world and respond by reimagining governance structures to meet the challenges of adapting to it.

While climate policy typically focuses on future decarbonization 10 to 20 years out, temperatures continue to rise. Greenhouse gases emitted upfront from the materials fabrication, construction, and renovation of our physical environment—embodied emissions—accelerate the rate of global warming now. They increase atmospheric carbon before our buildings and infrastructure are even used.
