LONDON — Hoping to replace that two-year-old smartphone in a few months? The European Union wants you to think twice about doing that.

The bloc announced an ambitious plan on Wednesday that would require manufacturers of electronic products, from smartphones to tumble driers, to offer more repairs, upgrades and ways to reuse existing goods, instead of encouraging consumers to buy new ones.

The “right to repair,” part of a wide-ranging policy package known as the Green Deal that was introduced this month, is the latest example of the European Union’s ambitions to promote more sustainable economic growth and to prevent waste. It extends standards brought in last year that put “right to repair” obligations on the manufacturers of some large appliances.

“The linear growth model of ‘take-make-use-discard’ has reached its limits,” Virginijus Sinkevicius, the union’s environment commissioner, told reporters in Brussels as he presented the “Circular Economy Action Plan,” which includes the “right to repair” initiative.
