Environmental sustainability

We aim to reduce our impact on the natural environment, both for our stakeholders and for the long-term sustainable growth of our business. As a technology company in the residential real estate sector, we have an opportunity to play a unique role, because where people choose to live may have an impact on emissions.

We are committed to improving how we manage our own impacts, and we are exploring opportunities to use our brand to influence positive change. We are also taking steps to address waste.

Our climate targets

To reduce absolute Scope 1 and Scope 2 GHG emissions 94% by 2030 from a 2019 base year.

To have 75% of our suppliers by emissions covering procured goods and services, capital goods and business travel with science-based targets by 2028.

Managing our carbon footprint

We are working to achieve our near-term science-based targets for reducing greenhouse gas (GHG) emissions, which have been validated by the Science Based Targets initiative (SBTi), as well as our goal of net zero GHG emissions by 2050.^{1, 2}

Every year, we complete an energy and GHG inventory of Scope 1, Scope 2 and Scope 3 emissions using the accounting methodology established by the World Resources Institute’s GHG Protocol. This work helps us measure progress against our climate targets.

We also obtain an independent, accredited third-party auditor to provide limited assurance of our Scope 1 and Scope 2 GHG inventory, as well as our Scope 3 emissions associated with procured goods and services, capital goods and business travel. We publish the limited assurance letter in our annual sustainability report.

Our progress toward our Scope 1 and 2 target is largely attributable to our purchase of renewable energy certificates (RECs).

We also are working to manage our energy consumption. Because our office space is leased, we collaborate with building managers and owners to gather energy-use data. We use our internal energy management dashboard to monitor and understand our energy-consumption trends, using data from lighting, HVAC, metering, appliances, generators and workstation plug load. We also use our corporate real estate lease operating procedures to gather sustainability information.

Managing climate risks & capturing opportunities

We recognize the importance of integrating climate risk management into our business, including by monitoring regulatory policy and analyzing how climate-related risk can impact our business.

We conduct climate risk scenario analyses to explore potential climate-related risks and uncertainties and to explore the resiliency of our business. We incorporate the outcomes of our analyses into our ERM function to enhance leadership visibility and the timely and efficient management of risks.

We also work to capture opportunities, including by providing more data and transparency to help our customers in their decision-making. Consumers can see climate risk data, with a link to dive deeper, on for-sale property listings displayed on Zillow’s website across the U.S. Some of our other products include a commute time filter, as well as our Walk Score, Transit Score and Bike Score. Where available, homes on our app and website show green-energy features, such as rooftop solar. We also use Zillow Research to examine how climate-related risk impacts the residential sector.

Electronic waste

Whenever we can, we partner with third-party vendors to divert our electronic waste away from landfills. These vendors do this by refurbishing and reselling, recycling and/or giving donated equipment away for free or for deeply discounted prices to communities with little access to these resources.

1 Limited to Scope 1 and Scope 2.

2 CA AB 1305 Disclosure: Zillow has a goal of reaching net zero GHG emissions by 2050 (limited to Scope 1 and Scope 2 emissions). As part of that goal, in September 2024, we announced the following near-term targets, which were validated by the Science Based Targets initiative (SBTi): 1) to reduce Zillow’s absolute Scopes 1 and 2 GHG emissions 94% by 2030 from a 2019 base year, and 2) for 75% of Zillow’s suppliers by emissions covering procured goods and services, capital goods and business travel, to have science-based targets by 2028. As reported in our 2024 Sustainability Report (the “Report”), as of 2024, we reduced Scope 1 and Scope 2 emissions by 97% as of 2024 compared to our 2019 base year—excluding Zillow Offers, which completed its wind-down in the third quarter of 2022—putting us ahead of our target. This was mainly driven by a combination of office space reduction and renewable energy certificate purchases. The Report also states that, as of 2024, 33% of our suppliers by emissions – covering procured goods and services, capital goods and business travel – have science-based targets. As described on page 40 of the Report, our 2024 historical Scope 1 and 2 emissions data and certain categories of Scope 3 data were subject to independent third-party limited assurance. See pages 53–54 of the Report for more information on our historical emissions accounting, including methodology, which we also use to annually track progress on our climate targets.
