A new paper by Motu Economic and Public Policy Research suggests a package of changes to improve the NZ Emissions Trading Scheme (ETS) The proposal’s proponents believes it would deliver clear and predictable emission price signals and ensure New Zealand’s emitters reduce their greenhouse gases more quickly.

Earthquake survivors could be rescued more quickly if the media communicated the number of likely fatalities from the outset, argues Professor Max Wyss For a decade, seismologists have been able to generate fast, reliable estimates of the number of people likely to have been killed in an earthquake, to within a factor of two or three.

Any pathway to reducing the country’s domestic emissions will involve substantial change to patterns of energy supply and use, according to a recent authoritative report by Vivid Economics Moving towards a 100 per cent renewables grid and substantial electrification of the passenger vehicle fleet and low-grade heat is a major measure outlined in the Net Zero in New Zealand: Scenarios to achieve domestics emissions neutrality in the second half of the century survey commissioned by Globe (Global Legislators of a Balanced Environment) NZ – a cross-party group of 35 members of Parliament.

The recent cyclone episodes and the associated flood events around New Zealand provide yet another reminder that the nation is extremely vulnerable to floods, experts advise “Once again, the recent flood events have demonstrated that they can have very adverse effects on communities causing damages, and trauma as well as disrupting daily lives,” says University of Auckland Department of Civil and Environmental Engineering Associate Professor Asaad Shamseldin.

Findings from researchers at Auckland’s Unitec Institute of Technology show a new way of managing land restoration that could revolutionise how mining areas are restored worldwide The process, known as ‘ecosystem-scale translocation’, was trialled over 75 hectares at the Stockton mine near the historic South Island mining town of Denniston and gives promise of immediate recovery for the animal and plant life, better environmental outcomes and virtually no long-term management costs.

The need for a cohesive strategy to drive reform of the country’s resource management and planning systems is now vital for New Zealand’s prosperity, says a coalition of like-minded organisations For some time the EMA, Property Council New Zealand, Infrastructure New Zealand and the Environmental Defence Society have been working together to build a case for change on how to provide for the nation’s growth and development within acceptable environmental limits.

Last November’s Kaikoura earthquake will likely change the way scientists think about earthquake hazards in plate boundary zones, according to the first study to come out of the data collected during and immediately after the earthquake Led by GNS Science researchers, the study reviewed a range of data – including satellite radar imagery – that shows that parts of the South Island moved more than five metres closer to the North Island, in addition to uplift of up to eight metres in some places.

New Zealand growth based largely on exploiting natural resources is starting to show its environmental limits with increasing greenhouse gas emissions (GHG) and water pollution, according to the latest OECD report While the country only accounts for a tiny share of global emissions, the OECD’s third Environmental Performance Review of New Zealand finds that intensive dairy farming, road transport and industry have pushed up gross GHG emissions by 23 per cent since 1990.

The increase in pollution and contamination incidents in New Zealand means businesses are becoming increasingly vulnerable to the potentially high financial cost of such events, a leading insurance expert says Delta Insurance General Manager Craig Kirk says various combinations of traditional liability policies, albeit each coming with their own exclusions, only serve to paper over environmental liability cracks.
