Imagine a world that is sustainable and equitable


I came to Brussels to work in the European Parliament just before the Fall of the Berlin Wall. The feeling of optimism for positive change and building bridges for a better world has remained with me.

I founded Conscience Consulting in 2008 as the first sustainability agency in Brussels, the first ethical advocacy agency, the first change agency. 






In a planetary emergency, businesses need to transform themselves into more sustainable, resilient and responsible organisations.


Wherever you are on the sustainability journey, we can help speed your progress.


A sustainability narrative is front and centre as a bridge builder of any successful public affairs strategy.


One of our assets is the strength of our ethics and our reputation for integrity among policy makers, NGOs and business leaders.



Conscience is a change agency – In a world in transition, we believe in the positive impact of ethical advocacy and climate diplomacy. We build bridges for inclusive sustainable societies. We convene coalitions and design campaigns that drive positive change. We are driven to innovate, committed to integrity, delivering influence. We’re working to help shape a world that is environmentally sound and socially just. 

We convene policy pioneers in progressive partnerships to drive ambition and action on the EU Green Deal. We consult with the architects of the Green Deal and the activists in EU Institutions. Our perspective on possibilities and power enable businesses to transform in partnership with civil society and policymakers.

Conscience has longstanding relationships with independent experts in Brussels and is the founding partner of a global network of independent sustainability consultancies with affiliates in Berlin, Buenos Aires, London, Paris and San Francisco. 


We carefully select the clients we want to work with. We have crafted narratives, messages and slogans for 100s of campaigns to build support for global goals.

We have done a lot of meaningful work and focus on these five major areas. Please click on a box below to find out more.







At Conscience we believe in purposeful communication to reach positive policy outcomes. Our theory of change anchors our work and enables clients to achieve advocacy ambition.

As a client you benefit from our unique experience, insight and perspective, as well as new tools of ethical advocacy and climate diplomacy.

Working with us means stepping up to become an essential policy partner.


At Conscience, we believe in ethical advocacy. We choose our assignments carefully as we are part of the Green Deal policy making circle.

Our Green Deal advocacy helps policy makers reward sustainability trailblazers with opportunities to collaborate as strategic policy partners and to level up policy ambition.

Sustainability Communication

At Conscience we have been communicating on sustainability policies and practices for more than 20 years.

The EU Green Deal provides novel opportunities for Institutions and brands to communicate how their sustainability priorities contribute to future wellbeing.

Strategic Coalitions

We are widely reputed at Conscience for our climate diplomacy, building bridges between leaders of NGOs, Institutions and Business into effective partnerships for advocacy and communication.

Convening roundtables that bring together knowledge partners with industry and policy partners proves effective for constructive dialogue on the complexities of policy intersectionality and to strengthen policy partnerships.


A core component of our theory for change is a bold narrative. We have worked with 100s of organisations to develop narratives that go beyond key messages.

Our narratives are compelling calls to action, anchored in immutable principles – inspiring, influential and integral to effective campaigns, coalitions and advocacy.


We share 30 years of know-how in bespoke training sessions that build the capacity of people, teams and whole organisations to be effective policy partners in EU Green Deal and UN SDG ambition.

Honing essential skills of narrative and strategy, the Conscience Masterclasses equip you for ethical advocacy and climate diplomacy – the new way of doing policy in Brussels.

We offer masterclasses to share our 30 years of expertise in sustainability communication

Building narratives

Learn how to frame your narrative, build your story and decide talking points. With so many voices competing for attention in Green Deal policy making, how do you make sure your campaign narrative is memorable?
A narrative that’s resilient to ambiguity and uncertainty will stand the test of time.

Crafting messages

Learn how to craft powerful messages that bring clarity to complexity. Rolling out new campaigns, commissioning new research or programming events without first crafting key messages is a costly mistake. Every briefing paper, speech and video should live and breathe your key messages.

Crisis communication

Learn how to keep calm and communicate in the face of massive uncertainty. From one day to the next, crises can hit, leaving leaders reeling with uncertainty as to what to say, when and how. Recent years have provided us plenty of experience to help you steer a clear approach.
