Ask your employer whether they have a list of volunteer opportunities they support or resources for you to use to find a match for yourself. Also find out if they offer incentives to employees for volunteering. The incentives might be allowing flexible leave or even paid time to volunteer (although if you get paid for the time it shouldn't be called volunteering).
"As more employees see volunteer work as a way to learn new skills or move their careers forward, volunteering has become a sort of corporate benefit. Companies are increasingly offering time off for volunteer projects, volunteer work on company time or company-organized efforts."
