2021 Owens Corning Sustainability Report | Expanding Our Social Handprint | Health & Wellness | 270 We continue to track our employees’ metrics as they relate to their health and well-being. Through the aggregate data we receive, we are best equipped to provide wellness programs that meet the specific needs of our people. HEALTH & WELLNESS PERFORMANCE Metrics Dashboards Our metrics dashboards track our facilities’ success and provide up-to-date information on programs, offering transparency about our healthy living efforts. In addition to the pillars and wellness teams, we implement policies that help drive better health. 2021 GOAL 2020 TOTALS 2021 TOTALS Platform enrollment 80% 78% 73% Platform engagement — earning >12,000 points (average of available quarterly data) 60% 41% 39% Health risk assessment questionnaire completion 60% 53% 48% Biometrics screening completion 60% 38% 40% Average steps per day for employees enrolled in the program 5,000 3,623 3,130 Average steps per day for employees who are enrolled and tracking 9,000 8,083 7,989 Employees reporting they are tobacco-free (2021-2022 open enrollment data) 90% 87% 82% With aggregate data from both our insurance carrier and the platform in the U.S., we are able to see the connection between participation and health improvements. Although enrollment in the Healthy Living platform went from 78% in 2020 to 73% in 2021 and engagement with the platform went from 41% in 2020 to 39% this year, participation rates in key areas such as biometric screenings, improved and are expected to return to pre-pandemic levels with our continued emphasis on employee well-being supported at all levels of the organization. Our aggregated data found a high correlation between participating U.S. employees and reduction in disease risks among our employees. Our data indicates that increased engagement with the Healthy Living platform is correlated strongly with a lower risk. The conclusions we have drawn from this data will continue to guide us as we develop new initiatives and maintain existing ones: ■ Employer support for healthy habits makes a difference. Our analyses show that higher levels of participation in the Healthy Living program are quantitatively linked to better health among Owens Corning employees. ■ Better biometrics correlate strongly with better (lower) health risk scores. ■ Higher participant points (top 20% of participants) correlate strongly with better (lower) sample health risk scores. ■ Higher points-based participation measures (top 20% of participants) are strongly related to smaller increases in risk score, BMI, and blood glucose over time. Opioid Prescriptions In response to the U.S. opioid crisis, Owens Corning’s policy limits short-acting opioid prescriptions to a three-day supply. Any pills dispensed beyond the three- day limit must be authorized. This policy decision was informed by a report from the Centers for Disease Control and Prevention indicating that addiction rates to a prescribed opioid can double after four to five days of continued use. We observed the following in 2021: ■ An 11.8% drop in opioid pills dispensed from 2020. Since the three-day limit was implemented, the number of pills dispensed has dropped by 57%. ■ There was a 15% drop in pills dispensed on prescriptions longer than three days compared to 2020 — a reduction of over 50% since the limit was implemented. ■ In 2021, the number of prescribers asking for authorization beyond the three-day initial limit decreased by 1.3%.
