Britain’s high-speed rail project is making a renewed effort to emphasise its environmental credentials. They will make an appearance at COP26 in Glasgow. Well, a virtual appearance – which is actually quite environmentally aware of the HS2 company. With a huge commitment already made to rail freight in the decade-long construction phase, the high-speed rail project is making delegates in Glasgow aware of its overall contribution to the UK network. Part of that is the climate-changing potential of using the released capacity for rail freight.
