This report assesses the progress of 55 of the largest U.S. corporations in reducing greenhouse gas (GHG) emissions in line with the Paris Agreement’s objective of limiting global average temperature rise to 1.5 degrees Celsius above pre-industrial levels, which requires achieving “net zero” emissions by 2050. The primary finding from our analysis is that the overwhelming majority of companies assessed have neither established comprehensive, 1.5 degree-aligned GHG reduction goals nor demonstrated progress in reducing their emissions in alignment with net zero goals.
