The Norwegian Prime Minister Jens Stoltenberg, said that Norway will reduce its emissions of greenhouse gasses by 30 percent by 2020, and be carbon neutral by 2050. “This does not mean no emissions … But it does mean that each tonne of greenhouse gases emitted is to be offset by an equivalent reduction elsewhere. This adds up to zero emissions”. See the speech here. Greenpeace gave a guarded welcome “It should do more at home rather than using its vast wealth to buy its way out of the problem. Norway should take responsibility for the 500m tonnes of emissions that it causes by its exports of oil and gas”. Yet it is still impressive. Who will follow?
