How we gathered our sustainability data 

With the help of the consulting firm Deloitte, we conducted a study in which we quantified for the first time the environmental and economic impact of buying and selling reused items on Wallapop based on their life cycle.

Where did we get so much data?

It’s easy! We have selected more than 50 products representing 86% of the total sales through Wallapop. We then analyzed the impact of these items being bought as substitutes for new products and how much they saved in production resources and waste.

How did we calculate them?

These results you have seen include the impact of each product, multiplied by everything sold on Wallapop in 2022.

And to be more rigorous, we have taken into account how many reused purchases on Wallapop actually replace the purchase of new items and the impact of the use of older and less energy efficient products such as motor vehicles, washing machines or refrigerators.

What about the equivalences of each amount?

Equivalences are the examples we show to explain the amount of resources saved and reduced by buying reused items. To explain them, we relied on various databases, academic studies and other sources.

These include Impact CO2 calculators, built with open data from ADEME, the French agency for ecological transition; publications from Harvard Health Publishing and Fundación Aquae; reports on packaging and recycling from sources such as Ecologistas en Acción, Coca-Cola, the Economic and Commercial Office of the Spanish Embassy in London or the Commission for the Promotion of Plastic Bottle Recycling in Japan, among others.
