its a load of s**t.
the first thing being done at the start of a shift is to call the LAS and agree to cancel the 270k procedure.
as noted in our comments book:
1) another crap procedure forced on us with no consultation and by those who have never held a licence... it looks good on paper so it 'must' be a good idea.
2)to fly 270k for 30 miles over 3000 mile flight, what a massive difference that will make.
3)nats and airlines seen to be doing something about carbon emissions so they look all concerned if any outsiders poke their noses in.... when in fact it causes more hassle and increases work load.
i suppose next we will be told we are not to take aircraft off sids on deaparture fro things like P-RNAV and then get moaned at for not moving anywhere near as much traffic and crap presentation to adjacent sectors because we cant make standing agreement levels.
