Marriott International on Wednesday announced via a letter of intent to the Science Based Targets initiative a goal to reach net-zero value chain greenhouse gas emissions by 2050, and that it would set “science-based emissions reduction targets across all scopes, in line with 1.5 degrees Celsius emissions scenarios.”

The commitment is part of SBTi participants’ overarching goal of reducing emissions across all scopes swiftly and fairly in line with the Paris Agreement, with “transparent action plans and robust near-term targets.”

Marriott also will join the Race to Zero, a global campaign established by the United Nations Framework Convention on Climate Change.

The announcement comes a week after Marriott released its 2021 Serve 360 Report, which includes data on the company’s environmental, social and governance efforts from 2020, and in which it announced it would submit its letter to SBTi. 

Among the other travel companies that have committed to or set targets through SBTi are Accor, BCD Travel, CWT, Hilton Hotels Worldwide, Hyatt Hotels Corp., IHG Hotels & Resorts and Melia Hotels International. American Express on Tuesday announced a pledge to achieve net-zero global carbon emissions by 2035.
