Luxury fashion giant Burberry -- a LFW veteran -- is one of the handful of brands publishing scientific targets, reports AFP.
Known for its tartan branding, the fashion house recently raised its emission reduction goals and hopes to be carbon neutral by 2040.
But BFC chief executive Caroline Rush said: "To set carbon reduction targets, you need a team to be able to measure your targets, understand how to reduce them and then report on them."
"For a small business that's quite a challenge."
To help, the BFC now has some 50 businesses that will go through its "low carbon transition" programme for designers.
Ideally, advocates say the programme should be extended to help brands monitor and report their carbon reduction plans.
Copenhagen Fashion Week has taken its own step to require all brands involved to meet a series of environmental goals.
In the United States, reform could come with a "Fashion Act" under consideration by the New York authorities, which would legally require businesses to cut emissions and take into account those of their entire supply chains.
"I think a lot of the issue is (that) the fashion industry can try to handball its problems to other industries," said CFJ director Emma Hakansson.
She explained that while there are many discussions on the climate impact of the meat industry for example, there wasn't the same pressure on producers of such materials as leather, wool and cashmere.
And yet the latter "are coming from the same supply chains", which use large quantities of water and emit methane.
