New Zealand Energy and Climate Change Minister David Parker has released the Government’s draft energy strategy. The strategy aims to ensure the country develops a sustainable and affordable energy system which minimizes greenhouse gas (GHG) emissions, and which will give New Zealand an enduring competitive advantage over other countries.
The strategy outlines major efforts in making electricity generation more renewable and in reducing GHG emissions from transport via a number of initiatives, including renewable fuels, increasing vehicle efficiency, and introducing plug-in hybrid electric vehicles.
The recently published New Zealand Energy Outlook to 2030 predicts the country’s oil use will increase by 35% and energy-related greenhouse gas emissions to rise 30% if no changes are made in the production and use of energy.
If we make no changes to the way we travel and transport freight, transport energy use is expected to grow by about 35% by 2030—with three-quarters of that growth coming from road transport. Greenhouse gas emissions from transport would increase at a similar rate. The risks of climate change make it unacceptable for us to continue on this path.
It is in New Zealand’s wider interests to reduce our transport emissions and our dependence on imported oil. Achieving this is likely to require, among other actions, a combination of biofuels and the use of electricity for vehicles.—from the Draft Strategy

The strategy proposes four priority areas for action, with a focus on reducing greenhouse gases:
- Developing and adopting future fuels;
- Improving the fuel efficiency of vehicles;
- Shifting to more efficient means of transport; and
- Ensuring a secure and diverse supply of transport fuels.
On the biofuels front, the strategy proposes establishing a minimum biofuels obligation, and developing transport policies over the next 15 years that will increase the proportion of biofuels in the fuel mix.
Because about 70% of electricity generation in New Zealand is already from renewable sources, the electrification of transport offers an attractive path to reduce transport greenhouse gas emissions, “as long as marginal new electricity generation has lower emissions per unit of energy required compared with fossil fuel alternatives.”
To date, electricity use for transport has been limited to buses and trains.
To adopt these technologies as early as possible, we need to consider and remove potential barriers to the introduction of hybrid plug-ins and full electrics into New Zealand.
Action: The government will consider establishing a group of experts drawn from research and industry to advance consideration of implications of moving to significantly higher levels of biofuels beyond 2012 and the introduction of plug-in electric vehicles (hybrids or wholly electric) in significant numbers.
Other key transport-related elements of the strategy include:
Improving the fuel efficiency of the vehicle fleet through age/technology standards.
Instituting education programs to improve driver behavior. Differences in driver behavior alone can vary fuel use by up to 35%, according to the plan, and it has been estimated that a targeted driver training program for heavy vehicle drivers could give energy savings of at least 10%, or 6.1 PJ per year.
Increasing support for public transport and non-motorized forms of transport.
Developing a New Zealand shipping strategy and other different ways to move freight.
Complementing the draft New Zealand Energy Strategy are two additional discussion papers. One is on the longer-term options for addressing greenhouse gas emissions across all sectors of the economy beyond 2012, and the other proposes transitional measures to encourage renewable energy and/or limit greenhouse gas emissions in the electricity and industrial energy sector as part of moving to the longer-term policy.
To reduce greenhouse gas emissions, New Zealand is likely to need a combination of voluntary, price-based and regulatory measures, some targeted towards individual sectors of the economy and some for the economy as a whole.—Minister Parker
The Minister begins the process for consultation on the draft strategy with a series of briefings to stakeholders this week. The closing date for submissions on the draft strategy is 30 March 2007.
