  13. land is used. For instance, a well-designed and stable NZ

    ETS will incentivise land-use change, including more afforestation. Introducing agriculture to an emissions price will also incentivise the search for, and adoption of, low-emissions practices and technologies. As noted, the short-lived nature of biogenic methane calls for a separate pricing system (such as an MQS) that reflects this property, while long-lived nitrous oxide emissions should be included in the NZ ETS. To reflect the trade-exposed nature of the sector, current technological limits, and the challenges around measuring on-farm emissions, a pricing system involving agriculture emissions needs to be carefully designed. The Government can best support the rural transition through stable policy, pricing emissions and supporting innovation, and making sure its investments in skills development, infrastructure and innovation are alert to the needs of emerging rural low-emissions industries. Transparency and advanced notice will provide clear signals while helping avoid significant economic and social dislocation in the transition to a low-emissions rural economy over the next three decades. Transport Transport is New Zealand’s second largest source of GHG emissions, contributing nearly 20% of gross emissions (and about one third of long-lived GHG emissions). New Zealand’s transport system is dominated by private road transport. Compared to other developed countries, vehicle ownership rates are high, public transport use is low, and the vehicle fleet is old with poor fuel economy. Rapid population growth and a decline in prices for fossil-fuel vehicles have caused the vehicle fleet to greatly expand. New Zealand’s transport emissions have risen more than any other emissions source since 1990. Adoption of EVs represents the most significant opportunity to reduce transport emissions in New Zealand. EV uptake is rising and costs will continue to fall, though price remains a key barrier as well as the limited travel range of current EV models. Fast uptake will be critical to achieve a low-emissions economy. For the bulk of light vehicles to be electric by 2050, nearly all vehicles entering the fleet would need to be EVs by the early 2030s. To encourage EV uptake, and catalyse the transformation to a low-emissions transport system, the Government should: y introduce a “feebate” scheme, in which importers would either pay a fee or receive a rebate, depending on the emissions intensity of the imported vehicle; y continue to provide funding for some EV infrastructure projects, to fill gaps in the charging network that are commercially unviable for the private sector; y raise awareness and promote uptake of low-emissions vehicles through leadership in procurement; and y require imported new and used fossil-fuel vehicles to meet fleet-wide emissions standards. New Zealand is one of a handful of developed countries without vehicle emissions standards, and risks becoming a dumping ground for high-emitting vehicles from other countries that are decarbonising their fleets. Decarbonising heavy transport (such as trucks, planes and ships) is more challenging than for light vehicles.

  19. LISTENING TO THE EDGE 32 One response: “Man the heat

    pumps!” are shown in per unit of heat output (cents per kWh). Fuel prices vary by region and provider/plan. The lower end of the running cost ranges represents the highest efficiency heaters and lowest fuel prices, with no fixed charges attributed to space heating. The higher end of the running cost ranges represents low-efficiency heaters, high fuel prices and fixed charges fully attributed to space heating (for natural gas and LPG (45 kg bottles) only). Heater efficiencies are based on typical highest and lowest heater efficiencies for new heaters. Non-ENERGY STAR qualified gas heaters and older heat pumps, wood burners and gas heaters may have lower efficiencies, resulting in higher running costs. For unflued gas heaters, 30% of the heat produced is assumed to be lost due to the need to leave a window open. Purchase, installation and maintenance costs are not included in the costs shown below. (Figure and data provided by EECA, 2017b)20 20 Fuel cost assumptions: Electricity 19–40c/kWh; firewood $50–150/m3; natural gas 5.4– 11.2c/kWh variable price; LPG (45 kg bottle) $92–110 per refill; LPG (9 kg bottle) $27–42 per refill. No fixed charges have been included for electricity, firewood and LPG (9 kg bottle). For natural gas and LPG (45 kg), fixed charges have only been included for the higher end of the running cost ranges. This assumes a total annual gas consumption of 3,000 kWh, fixed charges of up to $1.45/day for natural gas and up to $115 annual bottle rental charge for LPG (45 kg bottles). This represents households where gas is only used for space heating. For the lower end of the running cost ranges, no fixed charges have been included. This represents situations where gas is also used for other purposes than just space heating. 0 10 20 30 40 50 60 Heat pump Wood burner Flued gas heater - ENERGY STAR (natural gas) Flued gas heater - ENERGY STAR (LPG) Electric heater Unflued gas heater (LPG) Home heating running costs cents per unit(kWh) of heat released Source: BRANZ HCS 2015
