One indicator is the number of companies that have set emissions targets as part of the Science Based Targets initiative, or SBTi, a global nonprofit organization. That number grew from 164 companies in late 2018 to over 6,600 by November 2024. And thousands more have committed to lower their emissions. The Paris Agreement, an international treaty on climate change, aims to limit global warming to well below 2 degrees Celsius (3.6 Fahrenheit) and ideally to 1.5 C (2.7 F). Meeting the more ambitious target of 1.5 C will require reaching net-zero greenhouse gas emissions by around 2050. Net zero is the point at which the amount of greenhouse gases released into the atmosphere is balanced by greenhouse gases removed, either through natural sources like forests or technologies such as carbon capture and storage. To join the initiative, companies begin by signing a letter of commitment to set near-term (2030) and long-term (2050) targets for reducing their emissions. Companies have 24...
