With financial capital, when we spend too much we run up a debt, which if left unchecked can eventually result in bankruptcy. With natural capital, when we draw down too much stock from our natural environment we also run up a debt which needs to be paid back. If the stock of natural resources is at risk then our organisations are at risk and ultimately the planet and our human well- being is at risk. Hence, poorly managed natural capital becomes not only an ecological liability but a social and economic liability too.

Our ultimate goal is to improve biodiversity and human well-being by informing, advising & motivating organisations towards greater and more cost-effective investments in both.


Naturalogic, together with its partners, is helping companies, investors, governments, academics and opinion leaders to understand the economic consequences of natural capital impact and dependency. We aim to identify natural capital dependency across organisations, products, supply chains and investments and to manage risks from increasing environmental costs to ultimately build more sustainable business models and brands.

We aim to integrate the real cost to society and the values of nature into all major decisions affecting the environment and human well-being.

Key to our approach is that we not only quantify natural capital dependency, we also put a value on it, helping our clients understand environmental risk, in environmental but also business terms.

Correctly valuing natural capital will accelerate the transition towards a more responsible & sustainable world where products and services will internalise the true cost of the environmental impact to society.

We regularily use the following phrases to convince our future clients. Think about this:

“Privatising profits is good for entrepreneurship, privatising the impacts is good for sustainable development…if we privatise the profits, why not privatise the impacts?”

With CO2logic as a partner, we benefit of more than 10 years experience in climate & environmental services. CO2logic will remain an important partner for the CO2 related impact assessments, CO2 reduction advisory and CO2 offsetting expertise. There are multiple synergies that will benefit our clients..



But it’s not all about CO2, it’s also about water, land use, pollutants and waste. It’s about which raw materials are used and where they are sourced, from energy and water to materials, minerals and agricultural products. And it’s about how those materials are extracted, processed and distributed.
