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

Robert McLachlan Apr 18, 2021

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take fifteen months to prepare, so by the time they come out it’s very easy for commentators to point out that they are out of date.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

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

We (still) need to talk about cars - Planetary Ecology

Robert McLachlan Dec 16, 2020

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

Tourism and the ETS - The Dismal Science

Eric Crampton Dec 20, 2019

Eloise Gibson covers the carbon costs of tourism over at Newsroom: But in reality: “value-led tourism growth may actually worsen those pressures that are linked with consumption. Higher-value visitors, by definition, consume more goods and services, all of which have an associated greenhouse gas and solid waste footprint. To the extent that these goods and services are relatively energy … Read More
