We have the fourth highest per capita greenhouse gas emissions in the developed world. Based on the need to limit warming to 2 degrees C by 2100, our cumulative emissions, and our capability to mitigate, New Zealand should at least halve its greenhouse gas emissions by 2020 (i.e. a target of at least 40% less than 1990 levels). This target has a strong scientific basis, and if anything may be too lenient; reducing the risk of catastrophic climate change may require deeper cuts. Short-term economic costs of mitigation have been widely overstated in public debate. They must also be balanced by the far greater costs caused by inertia and the substantial health and social benefits that can be achieved by a low emissions society. Large emissions reductions are achievable if we mobilise New Zealand society and let technology follow the signal of a responsible target. | | Language | eng | | Pub Type(s) | Journal Article
