Instead of mines: Earth metals from garbage 

 

As much as 40 percent of China, the United States and Europe's rare earth needs by 2050 could be sourced from old electronics, according to a new research report obtained by the New York Times.

 

"Unlike fossil fuels, which are 'burned out' after they have been used, rare earth metals can be recycled," researcher Peng Wang writes in the study.  

 

Rare earth metals are a key resource in the green transition, but mining has been surrounded by both major environmental damage and violations of human rights, the newspaper writes.

Environmental researchers: Carbon dioxide deposit can solve 1.5 degree target 

 

A deposit fee on carbon dioxide emissions would make it possible to reach the 1.5 degree target, write environmental researchers Anders Lyngfelt and Mathias Fridahl on SvD Debatt.  

 

Whoever emits carbon dioxide is forced to pay to remove it from the atmosphere, according to the proposal. The deposit fee including return is refunded against verified certificates of negative emissions. Trading in mortgage bonds would enable long-term investments and technology development, the debaters write.  

 

"With the proposal, we are still handing over a carbon dioxide debt to our descendants, but also a financial asset that can pay the debt and thus solve a problem that otherwise risks being insoluble." debate Lyngfelt and Fridahl: "Introduce a deposit fee on carbon dioxide emissions"
