Big corporations are a leading contributor to global carbon emissions and their investment decisions have a
significant impact on the world’s ability to tackle climate change. This study combines corpus and discourse approaches to examine
how major corporate emitters have responded to the Paris Agreement, how they legitimize their practices amid mounting public
pressure, and how companies operating in high- and middle-income countries differ in their framing of climate change. The results
show that carbon majors place increasing focus on climate issues, widely support the goals of the Paris Agreement, and are
increasingly making net-zero pledges. However, close inspection of linguistic patterns reveals a troubling disconnect between
proclaimed goals, the solutions advocated for, and the radical steps needed to address the escalating climate crisis. Companies
from middle-income countries devote comparatively less attention to climate change, which points to the need for better
coordinated global efforts to address this problem.
