Reducing emissions impact
A new airport in Central Otago can help reduce New Zealand’s carbon emissions footprint in three ways. These are:
- All of journey emissions
- Airport operations
- Embodied emissions
We’ve developed a range of passenger scenarios to explore the total journey emissions of travelling to and from Central Otago – and getting freight to major freight hubs like Christchurch, Auckland and Sydney. You can see these below.
Early estimates suggest that as much as 500,000 vehicle kilometres per day could be added to the land transport network as a result of passengers travelling to Central Otago via Christchurch, Dunedin and Invercargill. Well placed infrastructure can reduce the emissions associated with travel.
Airport operations create operational emissions. A greenfield airport would provide an opportunity to reduce carbon emissions by using sustainable design principles, utilising renewable energy sources, implementing efficient transportation system and adopting environmentally friendly practices.
Embodied emissions are associated with the construction and maintenance of infrastructure. Within an airport, this could include construction and maintenance of facilities and supporting airport infrastructure, such as roadways, parking areas, fuel storage facilities and utility systems.
Embodied emissions can be reduced through sustainable construction, waste management and recycling.
Our early analysis shows that the embodied emissions associated with the construction of an airport in Central Otago would be substantially lower than those associated other alternatives such as upgrading the State Highway network or developing passenger rail services.
