Diversity, Equity, Inclusion & Access (DEIA)
GNA is committed to a policy of DEIA for all, which is reflected in our ongoing work and efforts in several ways:
- The work we’ve done for 25+ years to improve air quality in communities most impacted by diesel truck emissions, which are disproportionately low-income and communities of color
- Our ongoing events that feature culturally and gender-diverse speaker lineups and provide virtual, recorded, and hands-on opportunities to access to critical industry education
- Ongoing employee training workshops focused on unconscious bias, cultivating cultural competence, hiring and retaining a diverse workforce, and other timely conversations
- Our commitment to ensuring our offices, communications systems, events, and websites enable equal access for all regardless of ability
- The cultivation of a working environment that encourages employees to bring their whole selves to work so that they can shine individually and as part of collaborative teams
- Employee-led committee that strives to promote DEIA through the communication and collaboration of GNA staff, beneficiaries, and events
