The Science Based Targets initiative was established in 2015 to help companies to set emission reduction targets in line with climate sciences and
Paris Agreement goals. It is funded by
IKEA Foundation,
Amazon,
Bezos Earth Fund, We Mean Business coalition,
Rockefeller Brothers Fund and
UPS Foundation. In October 2021, SBTi developed and launched the world's first
net zero standard, providing the framework and tools for companies to set science-based net zero targets and limit global temperature rise above pre-industrial levels to 1.5 °C. Best practice as identified by SBTi is for companies to adopt transition plans covering
scope 1, 2 and 3 emissions, set out short-term milestones, ensure effective board-level governance and link
executive compensation to the company's adopted milestones. SBTi is a UK charity with a commercial subsidiary, SBTi Services, which offers to validate climate targets set by companies as science-based targets for a fee. As of 2025, SBTi operates without a central office and has 200 staff who primarily work remotely, including part-time employees. This has led to challenges in meeting the demands of a growing client base of companies seeking SBTi validation for climate targets. == Sector-specific guidance==
