About #SustainablePublicAffairs

Brussels Office Since

January 2020

Firm Description

#SustainablePublicAffairs is the first purpose-driven Public Affairs agency that only takes on cases that have a positive impact on the environment.


We work for sustainable frontrunners and want to make their performance the norm for the rest. We believe in market-led sustainability and advocate for regulatory conditions that support that.

We believe that public affairs should play an active role in getting us to a better tomorrow and is uniquely well positioned to do so. We hope to change EU policy into a more sustainable frontrunner-friendly environment.

Ownership Structure

SPRL with Willem Vriesendorp as only shareholder

Key Strengths

Our pledge to sustainability leads to three key strengths:

  1. We attract the best consultants, as today’s top talent is motivated primarily by working for a purpose.
  2. We can think transversally across all the different aspects related to sustainability, which leads to better, more creative approaches for our clients
  3. It gives us (and our clients) credibility and this spills over to our connections with the EU Institutions and relevant stakeholders.

We do not only want to talk the talk though – we like to walk to walk, too. Therefore, we also aim to be completely sustainable in our own operations.

Thought Leadership

We are the first purpose-driven Public Affairs agency that only takes on climate-positive cases and this (thought) leadership has been featured in news outlets like Politico and Le Monde.

To contribute to better and more transversal, multi-stakeholder thinking around sustainability we also have our own #SustainableBlog.

We also take a keen interest in academic thought leadership – an example being our contribution (as only the public affairs agency) to the Concurrences handbook on Competition Law, Climate Change & Environmental Sustainability.

Closing the Loop

“Public affairs doesn’t always have a good ring to it, so when we wanted to hire a public affairs agency, we wanted to be sure it had the same vision on sustainability. That is why we engaged #SustainablePublicAffairs.”


“It is amazing that just months after starting, they are so influential and successful already, and … this is just the beginning!”
