POTENTIAL SAVED EMISSIONS
It’s difficult to be certain that the production of new goods decreases as a result of secondhand trade and that each item not sold on any of the Schibsted sites is thrown away. Therefore, the results of saved emissions and materials are referred to as potential environmental benefits. We have been conservative when measuring the potential savings generated by our users, and aggressive when measuring impact from our own operations – the results communicated are based on prudent approach. We’d also like to point out that the life-cycle method, used in this study, is one of several ways to measure savings of material and greenhouse gases.
The study includes the following input data:
- Emissions generated by the extraction of materials used in products
- Emissions and material used for products
- Emissions generated by waste management products
- Emissions from transport of goods between buyers and sellers
- Emissions from energy use and business travel generated by our operations
The study has not taken into consideration:
- The use of the product, such as a car’s petrol consumption, is not included. This distinction has been done as the study focuses on the trading and production of goods, not their use.
- The climate impact of site visitors, i.e. energy consumption when visiting a site, is not included in the calculation in 2018.
THE CAR FACTOR
The study has taken into account that the car category needs specific clarifications and calculation adjustment, considering the fact that a car is usually re-sold several times.
Through second-hand trade two sources of new emissions can be avoided:
- The production of a new car and its materials
- The waste management of a car
A car can be up to 20 years old and still be considered viable from an environmental standpoint. This means that you can buy and sell a 20-year-old car and still reduce your carbon footprint compared to buy a new car since production represents the main part of the emissions linked to the life cycle of a car.
Reuse rate of cars:
For the car category, a calculation adjustment has been made to meet a more realistic scenario. In reality, cars are normally resold several times (regardless marketplace), this is exemplified by reuse rate. The reuse rate is the turnover of the national car fleet during the average lifespan of a car. Each country has its own reuse rate, but for two sites we have used an average (based on other countries data) since official data is not available for all countries.
Factors included in the calculation:
- X million used cars are resold during one year in private transactions in a country.
- Average lifespan of a car is Y years.
- The national car fleet is Z millions of cars.
Calculation of reuse rate:
- During Y years X million cars have changed owner (Y years x X million = YX million)
- This means that every car has in average been sold XYZ times during their lifespan (YX million/Z = W)
REFRIGERATORS AND FREEZERS
Old refrigerators and freezers contain dangerous substances (in refrigerators CFCs) and consume more energy (approx. 40 percent more). The Swedish secondhand site Blocket has chosen not to allow the sale of refrigerators and freezers older than 10 years since a new appliance is better for the environment compared to a used. Users are instead encouraged to deposit such items at environmentally responsible waste deposits for electronics.
