CoStar Group Signs Science Based Targets Initiative (SBTi) Commitment to Reduce Emissions

Commitment reinforces CoStar Group’s net zero goal by 2050 and builds on ongoing efforts to reduce emissions across the business

WASHINGTON, May 26, 2023–(BUSINESS WIRE)–Today, CoStar Group, a leading provider of online real estate markets, real estate market information and analysis, announced that its founder and CEO Andy Florance has signed a letter of commitment to set short- and long-term science-based greenhouse gas emission reduction targets in accordance with the Science Based Targets Initiative (SBTi).

SBTi’s science-based reduction targets are aligned with the level of decarbonization needed to meet the Paris Agreement goals of achieving net-zero global emissions by 2050 to limit temperature rise to 1.5°C above pre-industrial levels.

By signing the SBTi Commitment Letter, the CoStar Group expands on its previous work to track and report its baseline greenhouse gas emissions, including its Scope 1, Scope 2 (location and market) and Scope 3 relevant, as reported in its 2023 environmental report, Social and Governance Report (ESG). Prior to and since the publication of the company’s 2023 ESG Report, the company has solicited and will continue to solicit feedback from its investors on its climate-related work to date and its priorities for the future. The CoStar group will now proceed with the development of clear scientific objectives which will be submitted and validated by SBTi. SBTi’s science-based goals program provides a clear path for companies to reduce emissions and mitigate the impacts of climate change, while ensuring future business growth.

“At CoStar Group, we are proud of our commitments to reducing our environmental impact, and this is one of the pillars of our ESG objectives,” said Andy Florance, Founder and Managing Director of CoStar Group.

“In the past year alone, we provided over 30 million unique virtual tours of CoStar properties, which avoided approximately 130,000 metric tons of CO2e. We measured our greenhouse gas emissions baseline to track our future progress and have continued our work to decarbonize our office buildings and data centers. Signing the SBTi Commitment Letter is a natural next step in our work to become a net zero company.”
