Biodiversity and business: how Belgian companies turn commitment into measurable impact

Why biodiversity matters to Belgian businesses right now

Biodiversity is not a peripheral concern. It underpins every ecosystem service your business depends on: clean water, stable soil, pollination, climate regulation. Belgium's federal government recognises this explicitly, noting that companies must identify and evaluate their biodiversity impact and dependency across their entire value chain to develop effective instruments. That framing matters: biodiversity is infrastructure, not charity.

We see this constantly in our work with sustainability and HR managers at mid-sized and large Belgian companies. The conversation almost always starts the same way: "We know we need to do something for biodiversity, but we don't know what that looks like in practice, and we're not sure how to report on it or communicate it credibly." The ambition is real. The translation into action is where it breaks down.

In 2026, the pressure to close that gap is structural. The Corporate Sustainability Reporting Directive (CSRD) requires companies above certain thresholds to disclose material nature-related impacts, risks and dependencies. The EU Taxonomy adds further weight: economic activities must demonstrate they do not significantly harm biodiversity and ecosystems to qualify as sustainable investments. A policy statement and a carbon certificate no longer constitute a biodiversity strategy.

The Belgian Biodiversity Alliance, which brings together stakeholders across sectors to restore biodiversity through voluntary commitments, reflects a broader shift: companies are expected to move from reporting on biodiversity to actively restoring it.

What does a real biodiversity investment actually deliver?

A genuine biodiversity investment delivers three things simultaneously, and this combination is what makes it strategically valuable rather than philanthropic.

Measurable ecological outcomes. A corporate forest planted with native species generates hard data: hectares restored, species counts, carbon sequestration figures, soil health indicators. These are numbers you can put in a CSRD report, an annual sustainability disclosure, or a client presentation. They are verifiable, local, and grow in value year after year. Our company forest projects are designed from the outset to produce this kind of evidence, with 20-plus years of professional management built in.

Authentic communication material. A forest your employees helped plant, located near your offices, accessible to the local community, is a story no agency can fabricate. It is visual, physical and permanent. Marketing and communications managers who have worked with us consistently report that a corporate forest generates more genuine engagement, both internally and externally, than any campaign built around abstract sustainability claims.

Employee engagement and employer branding. HR managers are under pressure to demonstrate that their company's values are lived, not laminated. Involving teams in the planting and ongoing stewardship of a forest creates a shared experience with a tangible outcome. That is qualitatively different from a team-building day that leaves no trace. We explore this dynamic in more depth in our article on sustainable team building that creates real impact.

Why a structured partnership beats buying certificates

Purchasing carbon or biodiversity certificates has its place, but it is not a substitute for local action, and increasingly, stakeholders know the difference.

Certificate-based offsetting is remote, abstract and difficult to verify independently. It does not engage your employees, it does not improve the green space near your offices, and it does not generate the kind of storytelling material that builds reputation. When Atlas Copco Group conducted a formal Biodiversity Impact Assessment in 2024, the exercise revealed that meaningful biodiversity action requires on-the-ground intervention, not financial instruments alone.

A structured partnership with a specialist like Forest Forward means a physical project is designed, planted and managed in your local context. The BeBiodiversity initiative's BiodiversiTree tool, developed to help companies choose actions based on their situation, raw materials and location, reflects the same principle: biodiversity action must be specific, local and integrated into actual operations to be credible.

What we build — whether a corporate forest near your site, a Miyawaki micro-forest on your office grounds, or a restored green zone on a neglected parcel — is permanent. It is visible to your employees every day, to your clients when they visit, and to the community around you. That permanence is what makes it an asset rather than an expense.

For companies that want to start before committing to a full corporate forest, our collective planting programme Start2Forest allows you to purchase trees that Forest Forward plants annually on your behalf, with certificates and, for larger commitments, an invitation to the planting event itself.

How Belgian companies are already making this work

The pattern we see among Belgian companies that have moved from ambition to action is consistent. They do not wait for perfect conditions. They identify a concrete project, commit to it, and build their reporting and communication strategy around the results.

Sweco Belgium's position is instructive here: they frame biodiversity not as a compliance burden but as a driver of business resilience. That reframe is exactly right. Companies that invest in local nature projects are building relationships with their communities, demonstrating values to prospective employees, and generating ESG evidence that holds up to scrutiny.

The former Green Deal Bedrijven en Biodiversiteit, which ran in Belgium until September 2021, documented this in practice: biodiversity investments on business sites produced measurable increases in natural value, improved employee wellbeing, and strengthened stakeholder relationships. The Belgian Biodiversity Alliance continues this work, providing a framework for companies to make and track voluntary biodiversity commitments.

For HR managers specifically, the team dimension is not a side benefit. It is central. We have seen companies use the planting of a corporate forest as a defining moment in their culture, a shared project that employees reference for years and that new recruits cite as a reason they chose the company.

What Forest Forward handles, from first conversation to living forest

We manage the entire process. That is not a marketing claim; it is the operational reality that makes this work for busy sustainability, HR and communications teams who do not have the bandwidth to coordinate land, ecology, logistics, permits and stakeholder engagement on top of their existing roles.

Our process covers site identification and assessment, ecological design using native species appropriate to the local context, planting with employee involvement where that is part of the brief, long-term management over a 20-plus year horizon, and impact measurement that feeds directly into your reporting. For companies with legal obligations around tree felling in Flanders, our forest compensation service handles the administrative, legal and ecological dimensions of that process, turning a regulatory requirement into a genuine nature investment.

For companies that want to extend their impact beyond their own site, our school forest programme creates biodiverse learning environments on school grounds, combining corporate sponsorship with community benefit and strong external communication value.

Every project is designed to align with your values, your sector and your local environment. The result is not a generic green gesture. It is a project that is recognisably yours.

Biodiversity is not a line item in a CSR budget. It is a long-term asset that generates ecological evidence, employee engagement and authentic reputation at the same time, and no agency campaign can replicate what a living forest delivers. To turn that into a concrete project for your company, request a conversation with our team and we will map out what a corporate forest or nature restoration project could look like for your site.

Frequently asked questions

Why is biodiversity important for businesses?

Biodiversity underpins the ecosystem services that businesses depend on: clean water, stable soils, pollination and climate regulation. Beyond operational dependency, biodiversity is now a material disclosure topic under the EU's Corporate Sustainability Reporting Directive. Companies that cannot demonstrate active biodiversity stewardship face growing scrutiny from investors, clients and regulators. Investing in local nature projects turns this obligation into a reputational and employee engagement asset.

What is Belgium's national biodiversity strategy?

Belgium's federal government requires companies to identify and evaluate their biodiversity impacts and dependencies across their full value chain. The Belgian Biodiversity Alliance brings together stakeholders from all sectors to restore biodiversity through voluntary commitments, building on earlier initiatives like the Green Deal Bedrijven en Biodiversiteit, which ran until September 2021 and documented measurable gains in natural value on business sites.

How can a company measure its biodiversity impact?

Measurable biodiversity impact comes from physical, local projects: hectares of native forest planted, species counts before and after intervention, carbon sequestration data, and soil health indicators. These figures are verifiable and reportable under CSRD frameworks. Purchasing certificates provides no equivalent evidence. A corporate forest or restored green zone generates hard data that grows in value year after year and feeds directly into sustainability reporting.

What is the difference between a corporate forest and carbon offsetting?

Carbon offsetting is typically a financial transaction: you pay for credits representing emissions reductions elsewhere. A corporate forest is a physical project near your site, planted with native species, accessible to your employees and community, and managed over decades. It generates ecological data, employee engagement and communication material that certificates cannot replicate. It is also permanent and locally visible, which makes it far more credible to employees, clients and regulators.

How does a biodiversity project support employer branding?

Employees want to work for companies whose values are visible and lived, not just stated in a policy document. A forest your team helped plant, located near your offices, is a daily, physical reminder of that commitment. Companies that have built corporate forests with Forest Forward consistently report that new recruits cite the project as a reason they chose the company, and that existing employees reference it as a source of pride and connection.

How long does it take to set up a corporate forest with Forest Forward?

The timeline depends on site availability, ecological design complexity and the scope of employee involvement. Forest Forward manages the full process, from site identification and ecological design through planting and long-term management, which covers a 20-plus year horizon. The planting event itself, often the moment of highest employee engagement, can typically be reached within months of the initial project commitment. Contact the team for a project-specific timeline based on your location and ambitions.
