Zero Carbon Footprints and Ethics

Zero carbon footprints and ethics refers to the moral questions raised by efforts to reduce the greenhouse gas emissions of individuals, organizations, and nations to zero or net zero, including who is responsible, how burdens are shared, and whether offsetting is legitimate. The carbon footprint concept popularized individual accountability, and critics argue that it shifts attention from structural drivers. Hans Jonas's imperative of responsibility emphasized duties to future generations, and Peter Singer and Stephen Gardiner argued that affluent societies bear strong obligations because of historical emissions and capacity. Henry Shue developed the idea of subsistence emissions and fair allocation, and climate justice scholars such as Robert Bullard and Naomi Klein highlight unequal exposure and responsibility between rich and poor. Allan Schnaiberg's treadmill of production and John Bellamy Foster's metabolic rift locate causes in economic growth, while Arthur Mol's ecological modernization offers a more optimistic view. Anthony Giddens analyzed the politics of climate change, and Elizabeth Shove showed how practices and infrastructure shape consumption. Critics warn that offsets and net zero pledges can become greenwashing. Zero carbon footprints and ethics remains central to research on climate policy, consumption, justice, and sustainability.
