Does the world know how sustainable you are?

Since 2009 we have made local stories global. We find the drama in the data, and help businesses adapt to new market realities.

Sustainia Cities

We help cities attract new citizens, businesses, or investments by bringing their stories to life. We are experts on livability and have years of experience mapping the world’s leading urban climate solutions.

The Sustainian

The Sustainian is a brand new market guide for leaders – made by Sustainia. Our Host, Ralitsa Vassileva, gives you in-depth trillion dollar market guidance, first-hand talks with leaders, and scores of sustainable solutions to invest in, partner up with or purchase from.

Real Solutions on the Market

Together with UNGC & DNV GL, Sustainia has vetted more than 700 real solutions on the world’s largest sustainability market – the Global Opportunity Explorer.


Besides running The Sustainian, we help clients on an ad hoc basis. We create profitable sustainability strategies, build behavior- and mindset-changing digital tools, and bring brands to sustainability stardom.


We help organizations of all sizes and industries transform Global Goals into business goals, and refine their Environmental, Social and Governance (ESGs) criteria. Whether you’re experienced or just getting started, we can help your company realize the enormous business potential in the Global Goals, and make sure sustainability becomes a natural part of your strategies and operations.


We come from a world of publications but think digital into most of what we do today. We build impactful digital products for organizations who want to engage their stakeholders, showcase their work, or visually present their sustainability profile and overall strategy. We develop everything from games and apps to websites and interactive platforms, ensuring your organization gets just the right digital tool to get your audience activated.


Based on years of experience in strategic and operational communication, we help organizations build a credible and appealing sustainability brand or take their communications campaign to the next level. With a fundamental focus on storytelling, we shape engaging narratives tailored to your key community or customer-base, ensuring your annual sustainability reporting gets picked up, or that your new app makes a real impact.
