Pushing the boundaries: Scope 3 emission reduction

Driving change with a bold carbon emissions commitment (The Gigaton Challenge)


Practitioner Presentation
Thursday, Oct. 20 Location Code
9:30am-10:30am Sheraton Dallas Hotel ThS/48


This session will provide background on the value-stream commitments related to Scope 3 emission reductions.


Historically, the HVAC industry has been a significant source of emissions and energy usage. Fifteen percent of global greenhouse gas emissions are directly related to heating and cooling buildings. Trane Technologies’ 2030 sustainability commitments are meant to boldly challenge what’s possible for a sustainable future. The product-focused Gigaton Challenge is aimed at cutting customers’ emissions by one gigaton by 2030; this equates to about two percent of the world’s annual emissions.

The product-related commitments combined with leading operational commitments will help transform the built environment. This session will provide background on the value-stream commitments and, for Scope 3, it will explore the company’s pioneering level of accountability and details on the emission calculations that are inspiring new innovation, technology and collaboration. The session will also cover leader engagement, employee training, supplier and customer collaborations and other facets of this work.

There is an urgent need for bold climate leadership, and it’s going to take every company doing its part and taking responsibility. It will require industry and sector leaders within the built environment working with local city governments and world leaders.
