Yes. Employees who believe their company makes a real positive impact are consistently more engaged and more likely to stay, and sustainability is one of the most direct ways to create that belief. The effect is strongest when impact is attached to everyday work rather than announced once a year.
The key is not a sustainability message. It is a sustainability action an employee can see, ideally one tied to something they already do.
The link between purpose and engagement is now well documented.
- In Deloitte's 2025 Gen Z and Millennial Survey of more than 23,000 people, around 90% said a sense of purpose is important to their job satisfaction and wellbeing, and about 70% said a company's environmental record matters when they choose an employer.
- Workplace research repeatedly finds that employees who **strongly believe their company has a positive impact on society** are several times more likely to be engaged and to feel they belong.
- The pressure is commercial too: roughly half of B2B buyers already prefer sustainable suppliers, a share expected to reach two-thirds within three years (TRC Companies, 2026).
The pattern is consistent across studies. Purpose is not a soft benefit. It is a measurable driver of how people feel about their work.
If the evidence is so clear, why do so many green initiatives leave engagement flat? Three common mistakes:
1. It stays an announcement. A value on the wall or a line in the annual report is not something an employee can feel. Engagement responds to experience, not messaging.
2. It is disconnected from daily work. A once-a-year volunteering day is nice, but it sits outside the work people actually do, so it fades fast.
3. It is not believable. Employees can sense when impact is mostly marketing. Without proof, a green claim can lower trust instead of raising it.
The fix for all three is the same: make the impact concrete, tied to a real action, and checkable.
The most reliable method is to attach a real, audit-ready piece of impact to a specific behaviour an employee already performs. The task stays the same. Its meaning changes.
High-impact moments to target:
- Onboarding: a tree planted in a new hire's name in their first week.
- Training completion: finishing a module funds a concrete piece of regeneration.
- Milestones and anniversaries: marking time at the company with something that lasts.
- Surveys and feedback: completing a form triggers real impact, which also lifts response rates.
This is the model ImpactHero is built on. Each action funds trees planted into community-owned restoration projects, checked over their lifetime by satellite, drone and independent expert audits. We guarantee an 80% survival rate across all our projects, and many outperform that, so more trees end up standing than first planted. To date more than 600 companies, including Allianz, BCG and Humanoo, have used this approach, putting 3.6 million trees in the ground and funding roughly 36,000 days of paid local employment.
The point is that an employee can see exactly what their action did. That visibility, not the sustainability label, is what moves engagement.
Does sustainability really affect employee retention?
Yes. People who find genuine purpose in their work are more likely to stay. With around 90% of younger workers citing purpose as important to job satisfaction (Deloitte, 2025), a credible sustainability program is a meaningful retention lever, not just an HR talking point.
What kind of sustainability action engages employees most?
Actions employees can see and connect to their own work. Abstract pledges do little. A tree planted in someone's name, a training completion that funds restoration, or a survey that triggers real impact all work because the result is concrete and personal.
Is this just greenwashing?
It becomes greenwashing only if the impact is not real. The safeguard is proof: community-owned projects, independent audits, and a survival guarantee mean the action stands up to scrutiny. Concrete, checkable impact builds trust; vague claims erode it.
How quickly does engagement improve?
There is no fixed timeline, but the change usually shows first in how people talk about their work rather than in a dashboard. Most organisations start with one high-emotion moment, such as onboarding, measure the shift in sentiment, then expand.
Do we still need to do this now that EU reporting rules are lighter?
Yes. The 2026 Omnibus reduced mandatory reporting for many companies, but it did nothing to lower what employees and customers expect. Voluntary leadership now matters more, not less.
Sustainability improves employee engagement when it stops being a statement and becomes a visible, concrete action inside everyday work. Start with one moment, make it real, and let your people see what they helped create.
