Nanuk Asset Management was established in 2009 to develop world-leading expertise in the investment opportunities and risks associated with environmental sustainability and resource use efficiency.

Our focus is global and we invest in listed companies associated with the broad themes of clean energy, energy efficiency, industrial efficiency, waste management, pollution control, food & agriculture, advanced & sustainable materials, water and healthcare technology.

We are active, fundamental investors with a valuation based and research driven investment approach. Our portfolios are sustainably-themed and we incorporate positive and negative screening, ESG factors and values-based norms into our decision-making process.

Nanuk is an independent firm, privately owned by its founders and staff located in Sydney, London and New York.  We are committed to investing sustainably and managing responsibly on behalf of our clients.  



Nanuk believes that resource constraints and environmental challenges like climate change, pollution and water scarcity necessitate significant changes to business practices globally and that these changes will present significant long-term investment opportunities and risks.  Large parts of the global economy are already undergoing such transitions in industries such as clean energy, energy efficiency, industrial efficiency, water and waste management.

Nanuk believes that specialist active focus can be applied to investing successfully in these industries, which are often influenced by the complex interaction of government policy, new technology and changing industry structure, and which generally demonstrate higher volatility and inefficiency when compared with the broader equity market.

Nanuk acknowledges that “winning” products and technologies do not necessarily translate into successful businesses, nor indeed into good investments.  Our research is thus directed towards developing a deep understanding of individual companies and industry dynamics.  We combine this with robust valuation frameworks to identify good quality businesses that are both benefiting from evolving industry trends and have attractive return potential.



Nanuk’s commitment to managing responsibly is grounded in the firm’s Statement of Values which emphasizes the cultural and business principles by which the firm stands.

Trust and Integrity are the foundation of all of our actions.

Responsibility is first and foremost to our clients who have entrusted us with their capital, and also in positively contributing towards a more sustainable world for future generations.

Transparency and Clarity are central to our relationships with our clients and the way we work within our firm.

Open-mindedness and Independence of thought, combined with analytical rigor, are critical in developing and applying our investment insights.

Respect for others and Diversity of opinion allows us to challenge and sharpen our perspective, helping us to make the best decisions and achieve the best outcomes.

Collaboration and Teamwork are central to how our investment ideas are formed and translated into investment actions.

Our Passion for investing and our pursuit of Excellence compels us towards the achievement of long-term investment success for our clients.
