The Government has set what is says is an achievable, fair target for cutting atmosphere-warming emissions, but critics say the new target is "100 per cent pure spin" and a paltry increase on past commitments.
All countries are expected to set new targets for reducing greenhouse gas emissions before crucial climate change talks in Paris in December, which will establish a road map for the period after 2020.
Minister for Climate Change Issues Tim Groser confirmed yesterday New Zealand's target would be to reduce greenhouse gas emissions by 30 per cent from 2005 levels by 2030.
He described it as a "significant increase" on the 2020 target, which was a reduction of 5 per cent below 1990 levels. If the new target was set to a 1990 baseline, it was the equivalent of an 11 per cent reduction.
Labour and the Greens slammed the target, saying the Government should match the European Union by setting a target of at least a 40 per cent reduction on 1990 levels.
