The Science-Based Carbon Targets Initiative (SBTi), founded in 2015, is a global initiative launched by the Carbon Disclosure Project(CDP), the United Nations Global Compact (UNGC), the World Resources Institute (WRI) and the World Wide Fund for Nature (WWF) to help companies set ambitious emissions reduction targets based on the latest climate science, as part of the We Mean Business Coalition's commitment. The initiative defines science-based carbon targets and promotes best practices for science-based carbon target setting, provides resources and guidance to reduce barriers to application, and independently evaluates and audits companies' targets.

Science-Based Carbon Targets Initiative follow the latest climate science theory and are consistent with the measures necessary to achieve the Paris Agreement goal of holding global temperature increases to well below 2°C compared to pre-industrial levels and working toward a temperature increase of 1.5°C. SBTi focuses on accelerating corporate climate action to halve global emissions by 2030 and reach net zero emissions by 2050.

Since 2015, more than 3,000 companies have joined the initiative to set science-based climate goals, more than 1,000 companies have made net-zero carbon commitments, and SBTi links more than $38 trillion in market capitalization. Chinese companies that have joined SBTi include LONGi Green Energy, Vision, JD Logistics, Geely Automobile etc. 

科学碳目标倡议 （SBTi） 是成立于 2015 年，是由全球环境信息研究中心（CDP）、联合国契约组织（UNGC）、世界资源研究所 （WRI）和世界自然基金会 （WWF） 共同发起，帮助企业根据最新气候科学设定具有雄心的减排目标的一个全球性倡议，是全球商业气候联盟（We Mean Business Coalition）承诺的一部分。该倡议定义科学碳目标，并推广科学碳目标设定的最佳实践，提供资源和指南以降低应用障碍，并独立评估和审核企业的目标。

科学碳目标按照最新的气候科学理论，符合实现《巴黎协定》目标的必要措施，即与工业化前水平相比将全球温升控制在远低于2℃并努力将温升控制在1.5℃之内。SBTi聚焦于加快企业的气候行动，以便在2030年前实现全球排放量减半，并于2050年前达成净零排放。

自 2015 年以来，已有超过3000 家公司加入了制定基于科学的气候目标的倡议，超过1000家企业做出了净零碳承诺，SBTi链接的企业超过38万亿的市值。中国加入SBTi的企业包括隆基绿能，远景科技，京东物流，吉利汽车等。
