Douglas Elliffe, University of Auckland and Lindsay Matthews, University of Auckland   Can we toilet train cattle? Would we want to?

Sabrina Zwick, United Nations University   Work, education, entertainment, or simply better connectivity all draw people to cities. By the end of this century around 85% of the world population are predicted to live in cities. There are speculations that the COVID-19 pandemic will slow down this urbanisation trend, but I think it’s unlikely to stop it. Cities remain … Read More

What’s that? You wanted action, not just words, on climate change? And you wanted it now, not next year or the year after? How about something big, really big, maybe also diving right into the heart of an emotional, touchstone issue – say, the private car?  Welcome to the EV subsidy.

Why did New Zealand’s CO2 emissions blow out so spectacularly in 2019? - Planetary Ecology

• carbon emissions,
• climate change,
• co2,
• New Zealand stories

Every year in April, the trees start changing colour, the clocks go back an hour, and the national greenhouse gas figures are released and promptly forgotten. They take fifteen months to prepare, so by the time they come out it’s very easy for commentators to point out that they are out of date. Even now that the national media are … Read More

• carbon tax,
• Climate Commission,
• emissions trading scheme

My Dom Post column this week makes the case for a carbon dividend. Canada imposes a carbon tax on provinces that haven’t established their own carbon pricing regime, and is set to substantially hike the tax to $170/tonne.  How is it politically feasible? Money collected in each province is sent back as a grant to residents in each province. Carbon … Read More

• car industry,
• carbon emissions,
• Clean Car Standard,
• Fossil Fuels

To address climate change, we need to phase out the burning of fossil fuels. The largest share of fossil fuels is burnt in cars and trucks. So it seems clear that fossil-fuelled vehicles need to stop being designed, made, imported, and driven. But anyone who has visited a road or seen a car ad recently knows that that isn’t happening, … Read More
