As a champion of all things green, The Sceptic Tank is used to being assigned to the hippy camp by the climate-sceptic ilk, one of whom recently enquired if we would be "burning our bras this weekend to protest against Mongolian oil sands".
As we politely explained bra burning is an emblem of feminist activism against the objectification of women's bodies as mere sexual icons in a patriarchal society, rather than a symbol of environmental consciousness, while the tar sands project to which our amusing acquaintance was probably referring is in fact in Canada, rather than Mongolia. Moreover, bra burning is actually quite bad for the environment, emitting carbon dioxide into the air and wasting a perfectly good piece of lingerie.
As it turns out, it could be even worse for the environment than The Tank first thought after it today emerged that American bra maker Biflex has achieved an "above target" sustainability rating in Wal-Mart's latest supplier assessment report.
Biflex is soon to launch in the UK and we are looking forward to pulling on the OverBra, which not only "improves comfort and posture, lifting the bust and smoothing out contours for a sexy, feel-good hourglass shape", but is also made in a dyeing and finishing facility that has cut its water usage by four million tons, and waste water by seven million tons a year.
We're also delighted to hear Biflex monitors its own suppliers in Asia to make sure its "next-generation" fabrics are produced from recycled nylon that uses 50 per cent fewer virgin nylon materials.
The Sceptic Tank will definitely not be burning any bra made to this high sustainable standard; rather, we will be showing it off with pride, although perhaps not in the office.
