Sustainability & Communications

Based in Leuven, Belgium, Sustainability & Communications is a specialist PR and communications agency founded in 2018 that focuses exclusively on helping institutional organisations and socially conscious businesses communicate their environmental and social commitments. Operating from its headquarters at 79 Sluisstraat in the Flemish city, the agency brings together a small team of freelance experts who share a common focus on sustainability, science, and policy communication. Rather than offering broad corporate communications, Sustainability & Communications concentrates on outreach campaigns that require a deep understanding of complex environmental and social issues.

Specialist Expertise in Environmental and Science Communication

What sets Sustainability & Communications apart is its concentrated expertise in environmental communication, science communication, and EU communication. The agency works with organisations that need to translate technical or policy-heavy content into accessible messages for diverse audiences. This requires a strong grasp of materiality assessments, stakeholder engagement, and the ability to navigate the nuances of European Union policy frameworks. The team at Sustainability & Communications in Leuven brings experience in nudging—a behavioural science approach that encourages sustainable choices—and awareness raising, which are central to many of the projects they undertake. Whether the goal is to inform citizens about climate initiatives or to help a corporate client demonstrate its social commitment, the agency applies evidence-based communication strategies rather than generic PR tactics.

How They Apply Their Approach

The agency’s process typically begins with a communication strategy tailored to the client’s specific objectives and audience. This might involve a materiality assessment to identify which sustainability issues matter most to stakeholders, followed by the development of content strategies that align with those priorities. Sustainability & Communications then executes campaigns across paid, earned, shared, and owned media channels, leveraging media relations and outreach to secure coverage in relevant outlets. For internal communication, the team helps organisations engage employees in sustainability efforts, while external communication focuses on building public awareness and credibility. The agency’s work in EU communication often involves crafting messages that resonate across member states, requiring sensitivity to linguistic and cultural differences. All of this is done with a small, agile team that can adapt quickly to changing project needs, making them a practical choice for organisations that lack internal resources for dedicated outreach.

Services Offered by Sustainability & Communications

While the agency’s primary focus is on public relations and communications services, its capabilities cover the full spectrum of outreach and engagement. Based on the industries and keywords associated with the firm, typical services include:

• Communication strategy development, including materiality assessments and stakeholder mapping
• Content strategies for sustainability, science, and policy topics
• Media relations and earned media outreach
• External communication campaigns for environmental and social initiatives
• Internal communication programs to foster employee engagement
• EU communication and policy-oriented messaging
• Science communication and environmental awareness raising
• Nudging and behavioural communication techniques
• Corporate communication for socially conscious businesses

Who They Work With

Sustainability & Communications is best suited for institutional organisations—such as NGOs, research institutes, and public bodies—as well as businesses that are genuinely committed to social and environmental values but lack the internal expertise or time to plan and execute effective outreach campaigns. The agency is particularly valuable for clients that need to demonstrate their social commitment through credible, well-researched communication, rather than greenwashing or superficial messaging. Because the team is based in Leuven, Belgium, they are well-positioned to serve clients across the European Union, especially those involved in EU-funded projects or policy advocacy. However, their approach is equally relevant for local Belgian organisations or international companies looking to strengthen their sustainability narrative. For any organisation seeking to increase its social commitment and communicate it effectively, Sustainability & Communications offers a focused, expert-led alternative to generalist PR firms.
