Zillow Drops Climate Scores Amid Agent Backlash
2 Dec
Summary
- Zillow removed climate risk scores from listings after agent complaints.
- Agents feared scores negatively impacted property desirability and sales.
- Data provider First Street defends its climate risk assessments accuracy.

Zillow has removed climate risk scores from more than a million property listings, a little over a year after their introduction. This decision followed objections from real estate agents who reported that the climate data was negatively impacting sales and the perceived desirability of properties.
The climate risk scores, supplied by analytic startup First Street, were initially added by Zillow in September 2024, citing buyer concerns over climate risks. However, the California Regional Multiple Listing Service (CRMLS) led the pushback, with its CEO questioning the data's accuracy and impact.
First Street defended its methodology, emphasizing its reliance on transparent, peer-reviewed science and its success in accurately mapping wildfire and flood risks. Despite Zillow's removal, First Street's data remains accessible on platforms like Realtor.com, Redfin, and Homes.com.
