As we started to calculate the carbon footprints for our winter tours in order to acknowledge the sources of emissions and to better our sustainable travel planning, we ran into the problem of winter activities.
Skiing, ice fishing and snowshoeing needed no attention as they can be compared those summer activities with close to zero carbon emissions. The problem wasn't even snowmobiling as it can be calculated quite well knowing the distance covered in a safari, especially now with e-sleds (electronic snowmobiles) becoming more and more popular.
The problem was not being able to calculate the emissions of activities with animals, such as a husky or a reindeer safari. This was something we really wanted to do in order to have as truthful carbon footprint in our winter tours as possible. With our little knowledge of the animals and their caring it was not an easy task.
However, we managed to find information of the average weight of a husky as well as a reindeer. Then we continued to calculate the amount of food given to the animals per day and discovering the type of food that is used to feed them. After which we calculated the amount of carbon emissions of the food per day. Until here everything is just math.
The next part was difficult. Estimating the energy consumption of a husky and a reindeer on a safari. As you can understand this is something that should be researched more in order to obtain an accurate value. Anyway, we made an estimate value and this way we were ultimately able to calculate carbon emission values for both animal safaris.
We do want to highlight that the carbon footprints of our tours are not totally exact or accurate values of carbon emissions created on the tour and it is not their primary purpose. They are designed to give us and our customers an idea of where and how the carbon emissions are created and mostly to guide us to a more ecological travel planning as well as travelling.
