Lion Environmental

Who we are

Every excellent business is driven by an idea & a notion. Something magnificent, breathtaking, and so difficult to let go of, that it needs to be pursued. Ours is that our planet must master environmental business and social challenges to ensure sustainable growth, as a replacement for focusing on short-term financial interests at the price of future generations. There is a lack of equilibrium we have to balance. We need a new model. An environmental approach not exclusively based on measuring temporary shareholder returns, but on deeper, more meaningful, and more substantial for our earth. Why? Because we believe that development and modernization should – and can – create permanent change. We are committed that, in taking accountability for the most profound trials of our time, we have an exclusive opportunity to rethink the system and its organization. A new way of achieving progress and safeguarding robust and profitable business, while preserving a viable future.


We believe that as ESG consultants we have an energetic role to play. That we stand on the cliff of a fundamental change, facing a skyline of boundless prospects – new models, value and supply chains, technologies and ways of doing business, which must be executed with sustainable purpose. The big notion that drives us is to help organizations, businesses and entrepreneurs to reimagine their reality and move the world towards a new sustainable paradigm.

We are convinced that our planet needs a new sustainable model that takes the entire sustainable value chain into account to chance a system which should have been changed decades ago

Why we have what it takes

It takes a something special to change the world. And Lion has it. Our people are dedicated, daring and unafraid of pushing new limits & boundaries. Because who we are is not only about our legacy – it is about our entire approach regarding a greater cause. We were founded with a cosmopolitan ethos – interconnected to our eastern European heritage – that helped create a dream of independence spiced by ideals of multiplicity, inclusivity and open multicultural exchange. We are one of the only  independent eastern European consultancies with a strong national footprint regarding international clients and are one of the leading representatives of our industry. We made a promise to our clients & colleagues, both present and future, that we would be and stay an independent partnership. A home where a heterogeneous mix of people would own the business, so we could always exemplify diverse opinions, insights and judgements. We built the foundations of a sustainable ESG consultancy owned and operated by its people. People who feel accountable for the why, what and the how. We shaped a start-up culture into business by bringing a group of compatibles together and made entrepreneurism one of our essential beliefs to set us on a path of continuous learning, development and innovation. And we promised our clients that we would treat them with respect and integrity – and their business like we do our own.


Now,  we have seized our convictions and become the quintessence of the principles we envisaged. We are an independent firm, solely owned by our partners. As a true partnership, we fundamentally respect and understand entrepreneurs, because that is who we are. We are business partners for our clients: we create sustainable impact in times of development and fight for and with them in precarious situations. We believe in excellence – not distinction for its own sake, but the kind attained when people are trusted to realize their full potential and introduce innovation with purpose. We offer the exclusive combination of an analytical approach with an empathic attitude towards the environment and the people who live in it. We are down-to-earth people, diverse and authentic personalities and pursue to understand who we work with, to better meet their needs and provide traction. We bring sustainable transformation to life, investing in our clients to build resilient and robust organizations. And we discreetly trust in our entrepreneurial spirit, which keeps us on a path of constant detection, enabling our equals and our clients to take brave sustainable and entrepreneurial leaps, pass meaningful change and shift the sustainable paradigm.

Our Values

What Lion stands for?

Sustainable Entrepreneurship:

We understand entrepreneurial tests and know what makes successful sustainable entrepreneurs. This means actively exploring unconventional ideas, taking risks and blazing new trails, but also the willingness to assume responsibility when liabilities need to be overhauled. We encourage our employees to take responsibility for business decisions early on in their career. All of us are eager to find innovative and sustainable solutions to help our clients be "game-changers" in their environment and sector.


We achieve excellent results and develop best practices to ensure both measurable and sustainable success. Our goal is excellence in our work with clients, in the way we develop our knowledge and in our interaction with each other – externally and internally. To do so, we challenge ourselves time and again. We appreciate brilliant minds that create sound analyses and fact-based approaches. Investing in our employees' development is essential to ensure outstanding results for our clients and build long-lasting relationships with them. We value open discussion and debate in decision-making until the best possible outcome has been achieved.


We place ourselves in your position to be able to act as insightful, respectful and responsible advisors. Lion employees offer a unique combination of intellectual and emotional competence to meet our clients' aims and needs. We act as partners alongside our clients and focus on understanding the real problem, offering peer-to-peer advice and tailored approaches. Our firm is committed to tolerance and respect.
