NZ’s Paris emissions commitments should be 40% by 2030 and 100% (or more) by 2050 Gareth Renowden Jun 08

Submissions for the New Zealand government’s half-hearted consultation on post-2020 emissions targets closed last Wednesday. I managed to sneak my contribution in just before the 5pm deadline. It remains to be seen whether it will be read. I heartily recommend reading the Royal Society’s submission – a very clear statement of the issues and NZ’s […]

It’s deja vu all over again: NZ consultation on climate target set up to be a farce Gareth Renowden May 26

At the end of last week, with the deadline1 for submissions on a post-2020 target for New Zealand emissions rapidly approaching, the Ministry for the Environment released a second set of economic cost estimates for various emissions targets. These cost estimates are substantially lower, the Ministry admits, than the costs in the consultation document issued […]

Federated Farmers: sticking their heads in the soil? cindy May 12

Join the conversation at Hot Topic

Federated Farmers says farmers don’t need to worry about the causes of climate change, they only need to cope with the impacts. Feds President William Rolleston says they have “no position” on whether mankind is influencing global warming, and say that looking at the causes is not that helpful. No position? “We [farmers] need to […]

Milk cow blues: dirty dairy costs NZ dear, but methane cuts might work Gareth Renowden Apr 30

There’s good news and bad news for New Zealand’s dairy industry this week. On the one hand, research has found a number of compounds that can cut methane emissions from ruminants (cows and sheep) by up to 90% by reducing populations of the bacteria that produce the gas. On the other hand, research into the […]

Climate battle at NBR: Rodney’s rubbish versus Wiggs wisdom Gareth Renowden Apr 26

Join the conversation at Hot Topic

New Zealand’s leading business media outfit — the National Business Review — has long dallied with climate denial, providing a platform for former ACT party leader Rodney Hide (amongst others) to push climate tosh. Last week Rodney used his regular opinion column to attack the government’s emissions policies (behind paywall) — fair enough, given that […]

NZ’s emissions target scam – Groser & Co’s creative accounting exposed Mr February Apr 20

Join the conversation at Hot Topic

Simon Johnson (aka MrFebruary) looks at how climate change minister Tim Groser and the National-led government intend to use creative carbon accounting to ensure that New Zealand meets its 2020 climate change target (a five percent reduction) in spite of emissions of greenhouse gases (GHG) projected to increase to 2020 and beyond. On 10 April […]

High Water – NZ climate comic anthology Gareth Renowden Apr 16

Scientists investigate how climate changes, politicians (should) decide what to do about it. Tough jobs. Artists have just as difficult a job: to comment on the reality and unreality they see in society’s responses to the climate threat, and by doing so motivate us to create a liveable future. In High Water, a new anthology […]

It is profoundly depressing to hear pundits and politicians talking about the prospects for economic growth with no reference to either equity or environmental constraints. In the case of New Zealand a “rock star” economy can apparently develop accompanied by dismaying levels of child poverty, excited expectations of new oil and gas discoveries which spell […]
