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