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.


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.

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

“Jo has been a huge asset to the organisation, knowing her way around the Brussels arena. She has been able to open doors in the EU Commission and in the NGO network and has helped the Association build a network of organisations with similar interests to support our work. Jo is proactive, provides insight and builds connections. She always goes the extra mile.”

Jennifer Lewis, Executive Director, International Biocontrol Manufacturers Association 

“Jo transformed our plan into a coherent and compelling strategy in just a few days. Pure agility. A joy to work with.”

Seda Orhan, former Partnership Manager, Pesticide Action Network


We have been communicating on sustainability policy issues for more than 20 years. We focus on crafting messages, storytelling and linking your specific issues to political priorities. Essential to success is effective writing, independent evidence and professional pitching to policymakers and to the press. 

Some examples of our press releases:

“Jo brings life to technical and complex issues putting the human voice at the heart of communication.”

Rachel Owens, former Head of EU Office and Corporate Accountability Campaign Lead, Global Witness

“Ahead of a major conference in Brussels I was somewhat worried about how we’d secure media coverage of a story with diminishing interest (Afghanistan). Having Jo on board relieved all such worries – not only did her media expertise and contacts ensure we got positive messages across a wide range of international media, but her calm and methodical working style with me, colleagues and visiting delegates from Afghanistan made that our project so less stressful and ultimately more enjoyable. I could leave all media activities and decisions with Jo, certain they were being delivered effectively. The impromptu press conference was fantastic and impressively pulled off.”

Jenny Humphreys, former Programme Manager, Afghanistan Group (BAAG) for Afghan Civil Society


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.

“Jo Sullivan is an inspiring agent of change. She is an expert partnership builder who works round-the-clock to push the boundaries towards a more inclusive and sustainable society. I have personally enjoyed our conversations where she has challenged me to think bigger and more boldly.”

Mustan Lalani, Global Director Public Affairs, Tetra Pak

“Jo and I have worked together on campaigns and coalitions around the Green Transition. I very much admire Jo’s standing, integrity, e-intelligence and substance expertise: a winning combination and a magnet for multiple players of all backgrounds.”

Robert Madelin, Chairman, FIPRA International 


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 have been working with Conscience Consulting for years on a variety of projects. With the support of its creative, inspiring and impact-led team, we have been able to increase our exposure and create new partnerships.”

Céline Charveriat, as Executive Director, Institute for European Environmental Policy

“Jo’s breadth of knowledge and experience in EU public affairs and communication is remarkable. She has been instrumental to the success of our Europe-wide campaign and helped us formulate the narrative connecting the story to the messaging. We are delighted about our collaboration with Jo and would highly recommend her services.”

Tetiana Sykes, as Communications Manager, Mental Health Europe 


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.

“Jo is a wonderful guide in discovering your potential for improvement!”

Prof. Dr Maja Göpel, former Director Future Justice at the World Future Council, now Scientific Director, The New Institute, Germany 

“Thank you so much for the fantastic advocacy and communications strategy training. Jo opened our eyes to the importance of investing time into an integrated advocacy and comms strategy to ensure maximum and long-term impact. Jo made the theory tangible by providing a user friendly tool box that we can now apply to take forward our strategic work. We found the point on working with others who may not work on our issues insightful and inspiring – it is so true that everyone and everything is interlinked, and this nugget will help us to break out of our bubble, and ultimately to better protect refugees in the EU and globally.”

Maeve Patterson, Communications Officer, UNHCR the UN Refugee Agency 

“Jo is a charismatic trainer and team leader. During our collaboration Jo has always been extremely responsive, flexible and understanding of new challenges while always maintaining a positive and solution-oriented attitude. Her professionalism, knowledge and warm personality make a great coach in professional group settings. Highly recommended!”

Elina Baltatzi, as Outreach Officer, European Cyclists Federation
