Overhauling the steelworks in the way Tata has proposed could lead to a 1.5% cut in the UK's overall carbon emissions.
In Wales, we're talking about a drop of between 15-20%.
Environmentalists aren't necessarily celebrating though.
Many of those we've spoken to say more should have been done to prepare the local area for the change and secure new green jobs for the thousands now losing theirs.
Worth remembering too that when UK emissions stats are worked out they don't take into account the carbon impact of goods we import from overseas.
And critics say what's happening to Port Talbot will leave the UK reliant on shipping in steel from countries which aren't moving as fast to greener ways of working for several years to come.
