As a very young child, that same Orla asked if ash would frustrate the ducks. There is so much that we do that frustrates our indigenous flora and fauna, from the obvious acts of draining a wetland or chopping down a forest to the insidious and irregular negative effects of climate change. We know that climate change is caused by our emission of carbon, methane, and nitrous oxide, with the most vivid example being the burning of fossil fuels—oil, coal, and gas. There was the international Paris Agreement to limit temperature rise to 1.5 degrees' increase, and our Government has recently declared a climate emergency. The last Parliament unanimously passed the zero carbon legislation that created the independent Climate Commission that has just produced its draft budget, describing how New Zealand can be a low-emission country—that is, to reduce our reliance on using fossil fuels and reduce biogenic methane and nitrous oxide in agriculture. There is a lot that New Zealand can do to decarbonise, some of which is reflected in the Government's commitment for departments to be carbon-neutral by 2025, today's announcement of 22 new low-emission transport projects, and changes to public transport including the phase-out of public diesel buses by 2035.
