About #SustainablePublicAffairs

Brussels Office Since


Firm Description

#SustainablePublicAffairs is a first of-its-kind public affairs agency that only conducts business that has a positive impact on the environment.

It assists companies and organisations that go beyond current environmental standards and that want to raise those standards to gain a competitive advantage and capitalise on their sustainability lead.

It helps such “sustainable frontrunners” make their practices the market norm through EU policy, and only lobbies for cases that have climate positive impact.

Its mission is to foster policy-driven growth for sustainable business cases.

These are more than just words: #SustainablePublicAffairs is the first EU public affairs agency to have its positive impact on society and the environment certified by B Corp.

Check our #SustainableCharter on the website for more information.

We support sustainable frontrunners in the following areas: Agri-food, Sustainable finance, Sustainable Transport, Energy Storage, Carbon Direct Removals, Industry De-fossilisation, Sustainable Build Environments and Circular Economy.

With our clients and other mission-aligned actors we sit and work together to raise the bar on EU climate and environmental policy out of #SustainableHub – also known as the Permanent Representation of Sustainability to the EU.

Key Strengths

#SustainablePublicAffairs’ unique approach is based on three key pillars:

  • Quality: #SustainablePublicAffairs attracts the best consultants, as today’s top talent is motivated primarily by working for a purpose.
  • Impact: #SustainablePublicAffairs focusses on sustainability across the piece and only works on cases where it can have a significant positive impact. This helps transversal thinking across different aspects related to sustainability, leading to better, more creative approaches for clients – and hence more positive impact.
  • Authenticity: Choosing to work with #SustainablePublicAffairs demonstrates a clear intention of its clients: they want to “walk the talk” on sustainability and avoid conflicts of interest.
