New Zealand’s greenhouse gas emissions
By mid-June 2019, there were over
14,500
electric vehicles registered in New Zealand. Five years ago there were only 250
Manufacturing industries and construction Light vehicles 13.4% Other transport 6.4% Agriculture, Forestry, Fishing and Commercial Households 0.8%
8.6% 3.2%
Electricity generation 4.4% Fugitive emissions 2.4% Other energy industries 1.5%
EECA’s Strategic Focus Areas
Low Carbon Productive Business Efficient and Low Emissions Transport Energy Efficient Homes Government Leadership Engage Hearts and Minds
Efficiency First
- Energy Efficiency remains one of the greatest cost/benefit initiatives

Efficiency First
- Retrofitting existing energy systems
- New Investment opportunities
- Utilising the digitalisation revolution
- Well planned maintenance
- Price signals through the Emissions Trading Scheme
- Further Regulation
- Developing professional capability
“Innovations” in Energy Use
- Business
- Heat Pump Technologies
- Electrode Boilers
- Heat Capture and Reuse
- Transport
- EV’s
- Hybrid Vehicles
- Hydrogen – where will it go commercially?
- Residential
- Hot Water
- Lighting
- Space Heating
Increasing supply of renewable generation
- Geothermal will meet some demand
- Wind will be key
- Solar
- Grid scale booming worldwide
- Commercial/Industrial scale will develop
- Residential still has high payback scenarios
- Community schemes evolving
- Hydro
- Environmental considerations dictating
- Smaller scale to continue
- Biomass
- Options evolving but hampered by security of supply and cost
- Liquid Fuels are still costly
