At the end of June, Professor Jim Renwick of Victoria University gave his inaugural lecture. As you might expect of a climate scientist, it concerns what we know about the climate system and where we’re heading. He pulls no punches. Jim has been kind enough to put together a text version of the lecture for […]

Climate Action Tracker analysis: NZ emissions targets inadequate, not doing our fair share Gareth Renowden Jul 13

Climate Change Minister Tim Groser’s claim that New Zealand is doing its “fair share” of climate action has been blown out of the water by an international analysis [Full policy brief here (pdf)]. Once one removes what the Climate Action Tracker (CAT) calls the “creative accounting” of rules around land use and forestry, New Zealand’s […]

Climate change minister Tim Groser today released New Zealand’s Intended Nationally Determined Contribution (pdf) to emissions reductions after 2020 — a 30% decrease on gross emissions in 2005, equivalent to an 11% reduction on 1990 levels.

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.

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

Join the conversation at Hot Topic

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 […]
