2021 Owens Corning Sustainability Report | Expanding Our Social Handprint | Community Engagement | 244 COMMUNITY ENGAGEMENT PERFORMANCE As the world has begun to gradually emerge from the COVID-19 pandemic, our company-sponsored community outreach has begun to increase accordingly. It’s a testament to our employees’ eagerness to increase our social handprint through real engagement with the people in the regions where we conduct business. In 2021, Owens Corning employees volunteered 6,240 times, up 92% from 2020. They devoted 23,574 hours of volunteer time, an increase of 50% from the 15,690 hours in 2020. The work is valued at $28.54 per hour, totaling $672,793. Our facility engagement was 89%, which includes volunteerism and financial support. + Because COVID-19 restrictions are still in effect in places around the world, we are still experiencing lower rates of volunteerism than we saw in years prior. The upturn we have seen in 2021 is an encouraging sign that levels will continue to increase as restrictions ease, and we expect to see people return to volunteering at levels that exceed even those of previous years. The dedication employees have shown is still a driving force in our financial support. In 2021, 5% of our donations were charitable contributions and 95% were community investments.^ Cash contributions totaled $5,086,238, as well as $1,436,928 in in-kind giving, including $1,300,144 in product donations, projects/partnerships, or similar contributions.^ All our giving is accomplished with a management overhead of only $494,387, which includes salaries and fringes, computer equipment, phone equipment, travel, and other miscellaneous expenses.^ Photo submitted by: Audrey Patruno | Chambéry, France Global Finance Operations Reporting (GFOR) Caring Day
