Yesterday and today's investment in North America energy infrastructure will have a major impact on our ability to protect the global ecosystem for decades to come. As such, North American pipeline projects have become particularly controversial among climate justice advocates given their implications for carbon emissions, Indigenous land use and notably the way they lock in particular eoclogical futures. This presentation examines disputes over Canadian pipelines delivering natural gas, much of it from the US fracking industry, to the Mexican electricity sector, disputes which prompted threats of international arbitration between all three parties in the Canada- US - Mexico accord (NAFTA 2.0) less than a year ago. How are these disputes connected to continental and transnational ecological futures, and what are their implications for agrarian communities and Indigenous territories?
