• Paris Agreement,

Robert McLachlan, Massey University New Zealanders are polarised on climate change policy, according to a recent Stuff/Massey University survey of 55,000 readers. This puts the two major political parties in a difficult position as they seek options that are credible yet appealing to voters. Just 30% of Labour voters and 22% of National voters think the country is “more … Read More

Flight to nowhere sends the wrong message in climate crisis

Robert McLachlan • Sep 25, 2020

• climate change,
• flights,
• quantas,
• tourism

Qantas Airlines’ 7-hour “flight to nowhere”, that sold out in 10 minutes with prices from A$787 to A$3787, seemed like a sick joke to climate advocates. Apart from the waste of fuel and the pointless emissions, passengers would be able to see first-hand, from a plane just like those that carried coronavirus around the world so effectively, the sweeping devastation … Read More

A multitude of drops: Social tipping points in climate action

• climate change,
• decarbonisation,
• planetary boundaries

If you’re here, you probably know that the climate crisis is upon us, that it’s getting steadily worse, and that attempts to address it haven’t worked yet. People are still driving and even advertising SUVs with impunity, and oil companies are exploring like crazy, even in New Zealand. Politically, socially, economically, it’s a challenging problem. In Social tipping dynamics … Read More

• consumer,
• electric cars,
• environmental footprint

Yes. Reducing the number of cars in your household, or switching from petrol/diesel to electric, will dramatically reduce your greenhouse gas emissions. It’s one of the easiest and highest-impact climate steps you can take. New Zealand is being flooded with cars The New Zealand vehicle fleet is increasing rapidly.

On 27 September, Greta Thunberg addressed a crowd of 500,000 at the School Strike for Climate in Montreal, saying: “You are a nation that is allegedly a climate leader. And Sweden is also a nation that is allegedly a climate leader. And in both cases, it means absolutely nothing. Because in both cases, it’s just empty words. And the politics … Read More

A lot has happened since the UN’s report on 1.5ºC was released in October 2018. New Zealand’s Zero Carbon Bill has passed, and enshrines the 1.5ºC goal in law. The UK and France have also legally strengthened their targets to Net Zero 2050. The School Strike For Climate and Extinction Rebellion have become household names. But progress on the ground … Read More

Zero Carbon: It’s not just a good idea, it’s the law

Robert McLachlan • Nov 12, 2019

• climate change,
• greenhouse gas emissions,
• Zero Carbon Bill

Two years into New Zealand’s Labour-led government, the long-delayed Zero Carbon Bill became law on 7 November. Passed essentially unanimously, the lengthy public debates and political manoeuvring faded away until the final passage was even anticlimactic: Flipping through the @nzstuff @DomPost I was starting to wonder if I’d dreamt the whole #zerocarbonbill thing.
