Better Health for All

CoStar Group's operations generate positive health externalities through environmental initiatives. In 2022, the company recycled over five tons of computer equipment

and expanded its fleet of electric and hybrid vehicles, reducing fuel consumption by 160,000 gallons annually . It also reduced physical data center locations by over 75% , opting for LEED-certified and Energy Star-rated buildings to enhance energy and water efficiency, which mitigates pollution-related health risks. The company's core business of online real estate marketplaces, information, and analytics has no significant direct positive or negative health impact, and it generates no revenue from products with direct negative health outcomes. Its products do not have direct safety implications, carry health risks requiring disclosure, or have addiction potential. The company does not offer health-related products or services, nor does it collect or manage health-related data, or conduct clinical trials. In 2023, CoStar Group committed $18 million to Virginia Commonwealth University for a Center for Arts and Innovation , which is expected to indirectly support mental and physical wellness . In 2022, it committed $5 million over five years to Management Leadership for Tomorrow to advance career opportunities for Black, Latinx, and Native American students , potentially improving socioeconomic conditions that influence public health outcomes .

Fair Money & Economic Opportunity

CoStar Group's core business involves providing online real estate marketplaces, information, and analytics, rather than offering consumer lending, deposit, or insurance services. As such, most KPIs related to financial products, pricing, and customer financial health are not applicable to the company's operations. While the company invests in community impact and financial literacy, with contributions such as $1 million annually to the Management Leadership for Tomorrow program, $300,000 to the Virginia Ready Initiative, and nearly $300,000 for university partnerships

, the provided evidence does not specify these as a percentage of pre-tax profit for the 'profit_reinvestment' KPI, nor does it detail the reach or outcomes of financial literacy programs as required by the rubric for 'financial_literacy_initiatives'.

Fair Pay & Worker Respect

CoStar Group reported an 80% overall employee engagement score in 2024.

In the same year, the company maintained a 99% average monthly employee retention rate, which indicates an approximate 12% annual turnover. CoStar Group offers competitive salaries and benefits, including health insurance, stock purchase plans, and paid time off. In 2023, the average employee compensation package was $85,000 annually, including benefits compliant with labor regulations. The company has implemented ongoing training programs to ensure adherence to labor laws and reported an 86% DEI dimension score in its 2024 ESG Report. Despite these efforts, employee reviews and reports from 2022-2025 have cited concerns about micromanagement, lack of flexibility, unrealistic expectations, and a toxic work environment, with allegations of abusive behavior from management and extensive employee monitoring. The company denied these allegations.

Fair Trade & Ethical Sourcing

CoStar Group operates primarily as a provider of online real estate marketplaces, focusing on data aggregation and market analysis rather than the physical sourcing of materials. This indicates no material sourcing of at-risk inputs. While the company reported $49 million in direct spend with diverse suppliers in 2023, and a 261% increase in such spend in 2023, the total procurement budget is not provided, preventing calculation of the required percentage.

No specific, quantifiable data was provided for fair-trade certification share, audit frequency, forced/child labor incidents, traceability coverage, remediation speed, or the percentage of supplier contracts with enforceable ethical clauses.

Honest & Fair Business

CoStar Group released its 2024 ESG Report in May 2024, detailing efforts to enhance transparency and integrity, and noting improved scores with rating agencies such as MSCI, Sustainalytics, ISS, and JUST Capital.

In April 2025, the company announced board refreshment and corporate governance enhancements, including the appointment of a new Board Chair and the formation of a Capital Allocation Committee, aimed at strengthening oversight and ethical practices. However, in February 2022, reports emerged alleging excessive employee monitoring and public reprimands, which contributed to a significant turnover rate of approximately 37% in 2021.

Kind to Animals

CoStar Group Inc. operates as a provider of online real estate marketplaces, information, and analytics.

Its business model does not involve animal testing, animal agriculture, or the production of animal-derived products. Therefore, all KPIs related to animal welfare, testing, and sourcing are not applicable to the company's operations. While the company has green spaces and green roof gardens at its headquarters and a campus expansion, there is no measurable biodiversity impact or species recovery data to score wildlife conservation. Supplier audits and public policy engagement are general and do not specifically address animal welfare.

No War, No Weapons

CoStar Group Inc. does not engage in arms manufacturing or military contracts, focusing solely on civilian real estate data services.

Its operations are civilian-focused, indicating no revenue from defense contracts, no development of dual-use technologies, no defense business to oversee, no dual-use portfolio, no need for weapons red lines, no exposure to any weapons, no defense assets to divest, no applicable technology development in the context of peace vs military tech, no applicable ethical red lines related to weapons, and no military use of AI.

Planet-Friendly Business

CoStar Group's CEO signed a commitment letter in May 2023 to set science-based greenhouse gas emission reduction targets.

50% of the company's data center electricity comes from renewables. In 2022, CoStar Group calculated its baseline greenhouse gas emissions and completed the CDP questionnaire in 2023 with a score of C. The company's research fleet, with over 400 electric and hybrid vehicles, reduces fuel consumption by 160,000 gallons annually. Additionally, 130,000 metric tons of CO₂ were avoided via virtual tours, and over five tons of computer equipment are recycled annually.

Respect for Cultures & Communities

As part of its ESG initiatives, CoStar Group engages over 300 organizations to target underrepresented candidates.

Safe & Smart Tech

CoStar Group encrypts payment card data following PCI DSS, indicating compliance with some required certifications, though the scope is limited to payment card systems.

The company's cybersecurity risk management program follows the National Institute of Standards and Technology Cybersecurity Framework and includes asset assessments, a dedicated security team, and incident response plans. CoStar has not identified material risks from known cybersecurity threats. The company advocates for a balanced embrace of AI benefits while considering ethical challenges like bias and job displacement. In 2022, reports emerged of CoStar Group's employee surveillance practices, raising concerns about privacy and workplace ethics. A lawsuit was filed against CoStar in 2024 alleging collusion using data analytics to increase prices, which the company is seeking to dismiss.
