Reimagining work Providing increased work flexibility is critical to remaining competitive at a time when the demand for skilled professionals has never been higher. The COVID-19 pandemic offered us a chance to reimagine the way we work together. Over the last two years, we discovered we are united by a common sense of purpose rather than a location or an office. At TransUnion, we are fostering an environment of belonging and flexibility that supports associates in bringing their authentic selves to work while supporting their lives at home. Despite most of our workforce remaining remote today, we are redesigning our collaboration processes to enable post- pandemic hybrid and in-person work arrangements, in addition to fully remote options. We also expanded mental health benefits to all our associates and their families. We see mental health, work-life balance and wellness as fundamental parts of our culture. A supportive culture is necessary to do right by our associates and enable exceptional performance. In addition, we supported our associates’ abilities to bring their whole selves to work through our Diversity, Equity & Inclusion (DEI) efforts. In 2021, we increased DEI engagement by expanding unconscious bias training to all associates, enabling DEI roundtable conversations between associates and leaders, and offering tailored mentorship and development opportunities for associates from underrepresented communities, and much more. Addressing climate change We believe every sector of society must do its part to protect the planet, and in 2021, we focused our sustainability program on setting aspirational yet attainable climate goals. First, we established baseline metrics for our greenhouse gas emissions. But we didn’t stop there: We also launched scope 1, 2 and 3 climate change goals for the first time — pledging net-zero for scope 1 and 2 emissions by 2025, and at least a 30% reduction on leased real estate scope 3 emissions by 2030. You can read more about our position on climate change in our Appendix for recommendations from the Task Force on Climate-Related Financial Disclosures. Looking forward While we are proud of our 2021 sustainability advancements, we know there is more work to be done and we will continue to push for progress. In 2022, TransUnion will expand our financial inclusion footprint; key among our objectives is the launch of a new fairness framework to assess our products for disparate impact. Additionally, we will continue our environmental efforts, starting the process of identifying new renewable energy opportunities for our organization, and offsetting our emissions while also making meaningful advancements. Lastly, we will continue expanding our reporting on sustainability topics as we seek to fully align with the recommendations from the Task Force on Climate-Related Financial Disclosures. As we celebrate our continued progress, we look forward to expanding our contributions to create a more equitable society and healthy planet.
