Shelves full of old T-shirts, jeans, blouses and sweaters bathe the walls in colorful tiled patterns.

A slightly musty smell hangs in the air, and groovy jazz music crackles from a retro loudspeaker.

The cliché of second-hand shops is cult.

However, the market for used vehicles has long ceased to be a niche.

According to a survey by the statistics platform Statista, 48 percent of Germans have bought at least one part used in the last 12 months.

In addition to clothing, books, CDs, furniture and electronic devices are particularly popular.

The main motives of the buyers are clear: They want to save costs and also protect the environment.

In fact, there's a lot to be said for using items for as long as possible.

Because the ecological footprint is mainly created during production, says Melanie Jaeger-Erben.

She is head of the research group "Obsolescence as a challenge for sustainability" at the TU Berlin and the Fraunhofer Institute for Reliability and Microintegration IZM.

"With every year that a product is used longer, the ecological balance improves," says the researcher.

The fashion and entertainment electronics industry is probably one of the biggest climate sinners.

They alone are responsible for more than six percent of global greenhouse gas emissions.

Researchers at MIT have calculated that the production of a cotton t-shirt releases 2.1 kilograms of carbon dioxide (CO2) and equivalents and a polyester t-shirt even 5.5 kilograms.

A lot when you consider that every German buys around 60 new items of clothing a year – but often only wears them a few times.

For comparison: On average, 1 kilogram of CO2 equivalents is blown into the air on a 5-kilometer car journey.

1300 euros are slumbering in every household

Many also follow the latest trends at the expense of the environment when it comes to technology.

According to an evaluation by the Öko-Institut, the production of a television with a screen diagonal of 42 inches can cause more than 1000 kilograms of CO2 equivalents in production, and a smartphone produces around 100 kilograms of CO2 equivalents.

Then there is the consumption of resources: there are 30 different metals in a smartphone.

Nevertheless, Germans exchange their smartphones for a new one every two to three years on average.

It is not uncommon for the old device to simply end up in a drawer, although it is still functional.

Discarded smartphones are by no means the only treasures slumbering in German apartments.

According to a study by the Wuppertal Institute together with Ebay classifieds, there are unused items worth an average of 1300 euros lying around in every household.

Researcher Jaeger-Erben explains that the majority of Germans prefer to use new products because of our cultural background: "Novelty has a high priority in our material society," she says.

"We are very much geared towards wanting to have the latest innovations." This is associated with the fear of being left behind.

Most people felt more confident with a new product.

However, she makes it clear: "The new is not necessarily better than the old." This applies not only to quality, but also to the environmental impact.

After all, these also result from use.

New household appliances, for example, save more energy and water than older models, said Jaeger-Erben.

Nevertheless, due to the energy-intensive production, it could be worthwhile to continue using the ten-year-old washing machine.

Online shopping is more climate-friendly than its reputation

If you want to buy something second-hand or sell used goods for money, you can do this in the classic way at the flea market or in a second-hand shop.

However, online marketplaces such as eBay classifieds, Quoka, Hood, Fairmondo and the Vinted platform, which specializes in clothing, are more convenient.

There is more choice for buyers and a better price can usually be achieved as a seller.

Contrary to popular belief, it doesn't have to be worse for the environment.

An evaluation by the Federal Environment Agency shows that it can even be more climate-friendly to shop online than in the city.
