Picture the causes of air pollution in a major city and you are likely to visualise pollutants spewing out of cars, trucks and buses. For some types of air pollutants, however, transportation is … Read More

By Robert McLachlan, Massey University. The election of the sixth Labour-led government heralds a new direction for climate change policy in New Zealand. As part of the new government’s 100-day priority plan, it pledged to set a target of carbon neutrality by 2050 and to establish the mechanisms to phase out fossil fuels. In doing so, New … Read More

I’ve written a few posts in recent months about the connections between our immigration policy – materially boosting our population growth rate – and New Zealand greenhouse gas emissions (for example here and here). New Zealand is unusual because, as the Ministry for the Environment (MfE) has highlighted: • we have a fairly high rate of trend population growth, … Read More

The global warming limit set at the 2015 Paris Climate Summit is still possible, say scientists, but we need to redouble our efforts if the Earth’s atmosphere is to limbo under the ambitious boundary. In an article published today in Nature Geoscience an international team of climate scientists reports a re-assessment of complex Earth System Models. Crunching the numbers in light of new … Read More

By Quentin Douglas Atkinson and Shaun Hendy A little over half the world’s population sees climate change as a serious problem (54% according to a 40-nation Pew Research survey). Coincidentally, roughly the same number identify as Christian or Muslim (55%). On the one hand, these statistics speak to the success of climate change communication. In just … Read More

No, that blank space wasn’t a mistake. It was the sum total of everything MBIE has written or commissioned (analysis, advice, research, or whatever), in the period since the start of 2014 on how the appropriate or optimal immigration policy for New Zealand might be affected by commitments to reduce greenhouse gas emissions. At the start … Read More

A month or so ago I ran a couple of posts on New Zealand’s greenhouse gas emissions in international context. Readers may recall that New Zealand now has the second highest emissions per unit of GDP of any OECD country, having moved up from sixth in 1990. As part of the Paris climate change accord process, New … Read More

After my post the other day, I pricked up my ears when I heard on the radio that new data on greenhouse gas emissions had been released, and at the same time heard various industry lobby groups calling for more government support (money or regulation”) for this, that or the other mitigating measure. It is the costs of meeting … Read More

I’ve never had that much interest in climate change. Perhaps it comes from living in Wellington. If average local temperatures were a couple of degrees warmer here most people would be quite happy. And as successive earthquakes seem to have the South Island pushing under the North Island, raising the land levels around here – you can … Read More

Children alive today will find themselves living in a totally different climate in the future, should greenhouse gas emissions continue unchecked, warns a new study. Climate change does what it says on the tin – it changes the climate. The question of when and where we will start to notice those changes is tackled in a new, Kiwi-led study published … Read More
