Wilderness International

A CO2-Calculator for the medical sector

Whether you are a general practitioner or a dentist: with our tool especially for medical facilities, you can easily and free of charge calculate the CO2-footprint of various practices.

And then you can calculate the CO2-footprint directly by protecting valuable rainforest!

Climate saver forest

Compensation through old-growth forest protection

Primeval forests are real climate savers. They not only store huge amounts of CO2but also cool the environment, ensure stable rainfall and clean the air. And they are also a habitat for a huge variety of species!

Information on CO2-compensation

Doesn't compensation mean that emissions are reabsorbed? Is it better to plant trees or protect trees? Why does deforestation actually affect the climate? Many questions are answered in this interview with Kai .

About Wilderness International

 Wilderness International, based in Peru, Canada and Germany, purchases wilderness areas legally secure with land title and protects them for all future.

The purchases are refinanced through donations, which at the same time ensure the long-term protection of the areas as well as environmental education projects and research into CO2-storage and biodiversity.

I am convinced by the directness of the work. Instead of expensive awareness campaigns, WI actually protects unique wilderness areas. And not only the how, also the what has a hand and foot. Areas are selected on the basis of their acute threat, their ecological importance or their strategic location. All of this can be tracked by anyone using geo-coordinates. More transparency is impossible!

How we protect wilderness.

Our guide to saving the world.
Wilderness International


Find land plot

In rapid assessments, we work with researchers to determine the conservation value of a forest area. The decisive factors are whether the area has a high level of biodiversity and CO2 storage capacity, whether it is under threat and whether it is located in a strategically important place.


buy in advance

The purchase of the land is financed with loans. We do not collect donations for land that we do not yet own.


Land register entry received

We only work in countries with a high level of legal security and only buy land with a land register entry. All two or three foundations are entered in the land register.
Wilderness International


Create aerial images

We use drones to create high-quality aerial panoramas of our land. These are uploaded to our website. Each square meter is provided with specific geocoordinates.


refinance through donations

Anyone can donate to a specific piece of this wilderness area. The donation refinances the purchase and ensures long-term protection. Each square meter is only allocated once.


prove by document with geo-coordinates

Donors receive a personalized certificate with the exact geocoordinates of the piece of forest they have helped to protect. This makes the protection tangible and directly traceable.
Wilderness International


research, document, communicate

Environmental ambassadors and researchers visit the areas, conduct research together and experience the forest they are protecting. They then use the research findings, photos and videos for environmental education in schools and to get people excited about wilderness.


Ensure long-term protection

Regular visits, local partnerships, forest guardian:inside, property taxes and the foundation concept ensure the long-term protection and ecological integrity of the areas.

That's what we make of it.
