Ytterligare försvar av plastpåsen

Jag har skrivit om plastpåsar tidigare, men nu skriver The Independent om att även en engelsk statlig miljöutredning, trots tolv månaders vridande på siffrorna, kommit fram till att plastpåsar står sig väl i en miljöjämförelse - ur artikeln:

The report set out to find out which of seven types of bags have the lowest environmental impact by assessing pollution caused by extraction of raw materials, production, transportation and disposal.

It found that an HDPE plastic bag would have a baseline global warming potential of 1.57 kg Co2 equivalent, falling to 1.4 kg Co2e if re-used once, the same as a paper bag used four times (1.38 kg Co2e).

A cotton bag would have to be re-used 171 times to emit a similar level, 1.57 kg Co2e.

The researchers concluded: “The HDPE bag had the lowest environmental impacts of the single use options in nine of the 10 impact categories. The bag performed well because it was the lightest single use bag considered.”
