The Climate Change Response Act 2002 is the same age as this year's new voters. For 18 years, for their whole lives, they have had a dysfunctional law which has allowed emissions to rise and our planet to warm. This Act first came into force 18 years ago to ratify the Kyoto Protocol, which was built on the agreements from a whole 10 years before that in 1992 called the United Nations Framework Convention on Climate Change, or UNFCCC for short, which committed countries around the world to reduce greenhouse gas emissions. The Kyoto Protocol of 1997 accepted, firstly, that global warming was happening. And secondly, that, and I quote, "It is extremely likely that human-made CO2 emissions have predominantly caused it." The Kyoto Protocol recognised the basic premise of common but differentiated responsibility. That is that we all share the same atmosphere, but different countries have contributed different amounts to its warming and have a differing ability to change that. Many so-called developed countries have built their wealth off of the exploitation of our shared natural environment and therefore have a greater responsibility to draw down our carbon activity. It was not then immediately clear how we would go about drawing down this carbon but, as a wealthy country, Aotearoa New Zealand had an international obligation, and we recognised that in law.
