Almost all climate scientists agree that actions must be taken to lower carbon emissions, also known as greenhouse gases, to reduce the risk of damage to the environment and ultimately human health. A group of researchers say adding carbon labels to products could help change purchasing behavior and corporate supply chains, ultimately leading to large emissions reductions. They propose a private labeling system to fill the gap until national and international rules are adopted.
