In calculating the carbon footprint of products, efforts have been made to take into account all emissions produced by our guests. These include waste management, transportation / travelling, emissions of activities and accommodation services, as well as emissions from meals. The calculation does not take into account the emissions created before reaching the destination, f. eg. a flight from the guest’s home country to Finland.

Calculation process

The carbon footprint of waste management and transportation / travelling during the trip has been calculated with the Y-HIILARI tool developed by the Finnish Environment Institute (SYKE, 2019).

For waste management, the amount of waste for each day of the trip is estimated at one kilo of bio waste and one kilo of mixed waste, as well as 375g of plastic waste per guest.

Y-HIILARI's “Business Travel” tab has been used for CO2 emissions from transport and travel, from which it is possible to calculate emissions for travel by bus, train, taxi and car. (The tool can also be used to calculate flight emissions.)

Emissions from accommodation services:

The normal value for carbon dioxide emissions from accommodation services is calculated according to the Y-HIILARI table (SYKE, 2019) for business travel, where the average price of single accommodation in summer (1 April - 15 November) is € 70 or in winter (16 November - 31 March) € 110 and the environmental impact factor is 0.5 (CO2 eq kg / €), which means that one-night accommodation will emit a total of 35 CO2 eq kg/person in summer.

However, this does not support the differentiation of low-emission accommodation in our products, so the following criteria can be used to calculate truer values ​​for ecological accommodation:

We use an environmental impact factor of 0.4 for accommodation services that, to our knowledge, have committed some concrete actions and otherwise directed their actions to reduce their carbon footprint or other negative impact on the environment.

We use an environmental impact factor of 0.3 for accommodation services which, to our knowledge, have taken a number of concrete steps to reduce their carbon footprint and have already reduced their negative impact on the environment or operate in accordance with the criteria of sustainable tourism.

We use an environmental impact factor of 0.2 for accommodation services that are designed to operate with the smallest possible carbon footprint or as carbon sinks, and operate in accordance with the criteria of sustainable tourism in all their activities, constantly striving for a lower carbon footprint.

We use an environmental impact factor of 0.1 for accommodation services that do not have actual buildings or the accommodation is housed in nature, and operate in accordance with the criteria of sustainable tourism and constantly strive for a lower carbon footprint.

Emissions from meals:

Have been calculated with Unilever Food Solutions' (2020) CO2 calculator, in which vegetarian, fish, chicken and meat dishes have been calculated separately according to recipes retrieved online.

Average has been calculated for different diets, which is then used as a coefficient for each meal. For products with only vegetarian dishes, only the average vegetarian diet (0.78 kg CO2 eq) has been used. For other products, a separate average (1.12 kg CO2 eq) has been calculated for the mixed diet. This is done by averaging the averages of all the different diets.

We have not yet found a reasonable calculation formula for activities, so at present the carbon footprint has only been calculated for products where the activities are carried out with human muscle power, which means that they cause virtually no emissions.

Carbon footprint comparison for products:

The calculation of carbon footprints has been done for our own products, and for their mutual comparison only.

As a benchmark, we use the carbon footprint of one guest per night (total emissions of the product / number of overnight stays), expressed in kilograms of carbon dioxide equivalent (kg CO2eq). For example 70.8kg CO2eq / 4 (nights) = 17.7kg CO2eq (per person, per night)
