Don't fudge, says Benn?

According to the Standard

CABINET minister Hilary Benn today warned against fudging pollution rules to allow a third runway at Heathrow.

The Environment Secretary told the Commons that the Government had made it "very, very clear" that limits on harmful gases could not be ignored just to allow Heathrow to grow.

But the government's policy is not to ignore the rules, just to delay their implementation. Isn't that a fudge?
