About us
Founded in 2016, Sustinere has grown into the leading pan-Baltic advisor in ESG compliance, sustainability strategy, and responsible management culture.
Showing the way
As an independent agency owned by its founding partners across Estonia, Latvia, and Lithuania, we were one of the first dedicated sustainability agencies in the region — and yes, we were called crazy for it. Maybe we were ahead of the market, but that was always the goal. It’s how we’ve stayed at the forefront of solving the toughest challenges.
Team of 25 experts
Today, we’re a multidisciplinary team of 25+ ESG and sustainability experts, with backgrounds across industries like finance, manufacturing, agriculture, real estate, energy, telecom, mobility, and more. This diverse expertise, paired with our deep ESG and sustainability knowledge, empowers us to guide clients through the complexities of a changing business and environmental landscape.
Full-service agency
We help companies meet regulatory ESG requirements, craft sustainability strategies that resonate with clients and financiers, and uncover the risks and opportunities of sustainable business models.
Trusted partner
We partner with the largest and most forward-thinking companies in the Baltics and Nordics while staying true to our boutique agency roots — fostering close relationships, built on trust and transparency.
What’s driving us forward?
Companies have the power to take responsibility for a sustainable future and create real, positive change. So we’re dedicated to driving business practices that protect nature and people. Every word we speak and every action we take is aimed at making a lasting impact — because that’s the only way businesses and society can thrive. The future we see is a future where businesses succeed by doing good.
Staying true to ourselves
Mission-driven and independent
We’re here to drive change, guided by our values, not swayed by profit. Adaptive and business-savvy, we embody a “make change happen” mindset in everything we do.
Curious learners
Our advice is grounded in data, scientific understanding, and a clear grasp of real-world impacts. This is why we constantly explore and dig deep to ensure no insight is ever missed.
Practical and digital
We cut through the noise connecting insights in fresh, innovative ways. Combining expert knowledge with technology, we deliver efficient results.
Close partners
Trust and transparency are the foundation of lasting partnerships. Clients find us approachable, both in person and in spirit. We take our work seriously, but ourselves — not always. Fun is where discovery happens.
Approach
We’re here to be the all-in-one partner for strategic ESG and sustainability management, guiding clients from start to finish — or just the parts in between, wherever they need us most. With deep knowledge of regulatory requirements and market best practices, we calculate, plan, implement, and communicate clients’ ESG strategies. Always forward-thinking, we stay ahead of the curve by introducing new solutions for today’s challenges and tomorrow’s opportunities. Our goal? To drive real change within companies, and through them, in society.
Team
Our diverse team of passionate experts is united to make a meaningful, lasting impact. With backgrounds ranging from business leadership and environmental sciences to human rights, law, public policy, risk management, marketing, communications, and beyond, we bring an average of 7 years of hands-on sustainability experience to the table. We may come from many fields, but we’re all driven by the same belief in a sustainable future.
