New Zealand's greenhouse gas emissions have increased significantly since 1990. This article examines how the fact of increasing emissions is discussed and given significance in New Zealand's national public discourse on climate change. Greenhouse gas emissions became a serious public concern on 17 June 2005, when the New Zealand government estimated a $307 million Kyoto Protocol liability in its 2005 financial statements. Conservative media coverage of this report emphasised governmental miscalculation, the financial liabilities generated by Kyoto Protocol regulations and a struggle between Climate Change Minister Peter Hodgson and industry voices over how to define the problem. This article links the arguments and discursive strategies used in the 17 June 2005 newspaper coverage of increasing greenhouse gas emissions to the institutional actors shaping New Zealand climate change policy. The increased effectiveness of industry challenges to government climate change policy is noted and discussed.

ObjectiveTo compare the costs and climate impact (greenhouse gas emissions) associated with current and healthy diets and two healthy and environmentally friendly dietary patterns: flexitarian and vegan.DesignModelling studySettingAotearoa (New Zealand).Main outcome measuresThe distribution of the cost and climate impact (kgCO2e/kg of food per fortnight) of 2 weekly current, healthy, vegan and flexitarian household diets was modelled using a list of commonly consumed foods, a set of quantity/serves constraints for each, and constraints for food group and nutrient intakes based on dietary guidelines (Eating and Activity Guidelines for healthy diets and EAT-Lancet reference diet for vegan and flexitarian diets) or nutrition survey data (current diets).ResultsThe iterative creation of 210–237 household dietary intakes for each dietary scenario was achieved using computer software adapted for the purpose (DIETCOST). There were stepwise differences between diet scenarios (p<0.001) with the current diet having the lowest mean cost in New Zealand Dollars (NZ$584 (95% CI NZ$580 to NZ$588)) per fortnight for a family of four) but highest mean climate impact (597 kgCO2e (95% CI 590 to 604 kgCO2e)), followed by the healthy diet (NZ$637 (95% CI NZ$632 to NZ$642), 452 kgCO2e (95% CI 446 to 458 kgCO2e)), the flexitarian diet (NZ$728 (95% CI NZ$723 to NZ$734), 263 kgCO2e (95% CI 261 to 265 kgCO2e)) and the vegan diet, which had the highest mean cost and lowest mean climate impact (NZ$789, (95% CI NZ$784 to NZ$794), 203 kgCO2e (95% CI 201 to 204 kgCO2e)). There was a negative relationship between cost and climate impact across diets and a positive relationship within diets.ConclusionsMoving from current diets towards sustainable healthy diets (SHDs) will reduce climate impact but generally at a higher cost to households. The results reflect trade-offs, with the larger constraints placed on diets, the greater cost and factors such as nutritional adequacy, variety, cost and low-emissions foods being considered. Further monitoring and policies are needed to support population transitions that are country specific from current diets to SHD.

Political Consensus

The governments of New Zealand and Australia are proposing to implement greenhouse gas emissions trading schemes (ETS) to help drive down carbon pollution within their borders. Although both countries enjoy a political consensus in favour of emissions trading, the Parliament of each country is deeply divided along party political lines about the appropriate design of the irrespective schemes.

On Farm

Agriculture contributes about 60% of New Zealand's total greenhouse gas emissions. Management practices for reducing these emissions will be required to meet our future international commitments. This paper presents estimates of two practical on-farm measures for reducing total greenhouse gas emissions from an average dairy farm on the West Coast of the South Island of New Zealand: 1) the incorporation of cereal silage into the diet, and 2) the strategic use of a stand-off pad in winter. Total calculated greenhouse gas emissions were reduced by about 14% if fertiliser N-boosted pasture was replaced with bought-in cereal silage grown off-farm. The estimated reduction in emissions was due to reductions in nitrous oxide and carbon dioxide emissions, whereas methane emissions were not significantly affected by this management practice. Reduced methane emissions required an increase in per animal production and a corresponding decrease in stocking rate. The use of a stand-off pad during winter did not significantly affect total greenhouse gas emissions using current inventory calculations. However, recent research suggests that it may reduce emissions by 3 to 8%, when accounting for the seasonal variation in N2O emissions and reduced fertiliser N requirements due to reduced pasture damage. A preliminary assessment of the economic implications of the cereal silage option suggested the cost of using cereal silage is likely to be higher than any savings that could be accrued from carbon credits obtained from reducing greenhouse gas emissions. However, the costs associated with building and using a stand-off pad are likely to be off-set against a potential increase in pasture production, and carbon credits obtained from a reduction in greenhouse gas emission would represent a net cost saving.

The life-supporting capacity of New Zealand’s environments has been much reduced and the pace of degradation shows little sign of abating (Ministry for the Environment and Statistics New Zealand, 2015). Few countries are experiencing greater biodiversity loss, more rapid freshwater deterioration or greater per capita increases in greenhouse gas emissions (Myers et al., 2013; Parliamentary Commissioner for the Environment, 2016; Gluckman, 2017). The climate is changing fast and it is already clear that a number of communities cannot be sustained for more than another decade or two in their current locations.
