A net-zero pledge is a commitment made by individuals, organisations, companies, or even countries to achieve a state of "net-zero" greenhouse gas emissions within a specified timeframe. The term "net-zero" refers to the balance between the amount of greenhouse gases emitted into the atmosphere and the amount removed from the atmosphere.

The Science Based Targets Initiative is a collaboration between CDP, the United Nations Global Compact, World Resources Institute, and the World Wide Fund for Nature. 1,000+ companies have joined SBTi to make targets grounded in scientific principles. SBTi promotes science-aligned strategies for emissions reduction and net-zero goals.
