17-0202 v2.1/Te Wharehou O Tuhoe/Request for Exception to Purchase Carbon Offsets, By Installing Offsite Renewable Energy on a Community Development Not Seeking LBC Certification.


Tuhoe iwi accepted an apology and reparations settlement from the Crown in 2014 for 150 years of colonial impacts. Tuhoe now have significant control of their future destiny and are investing in their social, tourism and physical infrastructure, such as the Te Uru Taumatua whare  and other community developments. These will directly support their people and land through community employment, training, local business and tourism infrastructure. This will ensure they can flourish and live sustainably on their own land as a community for generations to come.

Rather than spend the critical settlement on buying Carbon Offsets on the international market, (which benefits distant peoples and countries’ transition to clean energy), the project team propose that the iwi’s significant investment in renewable energy on their own developments is recognised as having greater positive social, education and climate benefits.

The Tuhoe embodied carbon offset cost is approximately NZ$25K (Range NZ$8K - $25K).  Additionally the NZ electric grid operates around 80% renewable portion annually (subject to rainfall). The proposed exception offset investment is approximately NZ$100K of solar electric panels. This array is included in the construction contract, currently underway and will be installed on a remote rural development in Ruatahuna. 

The development consists of a general store, workshops, tourist accommodation, education and community support facilities. The installed solar array is approximately 20% of the development’s annual energy consumption.

This project at Ruatahuna will not be seeking LBC Certification.

In reality carbon emissions avoided in Te Urewera (Tuhoe country) by investing in renewable energy are still contributing to the global reduction in atmospheric carbon, whilst the investment has an enhanced leverage to create positive social, educational and environmental impacts for the local community and their visitors.

We can supply copies of documentation to confirm the investment.


The installation of an additional offsite solar array for community benefit meets the intent of this Imperative by providing additional renewable energy production to the grid (similar to the requirement of purchasing Green-e Climate certified, or equivalent, carbon offsets). The Institute has created a new Exception for this approach. Note the rate for New Zealand projects is provided in a footnote to the calculations, below. 
I11-E3 Installation of Off-site Renewables 
Installation of additional off-site renewable energy infrastructure, that does not serve the LBC project, may be used to satisfy all or a portion of the project's carbon offset requirement, as calculated in
"I11-1 Carbon Calculations". 
The default calculation methodology follows. Teams may apply 10 years of production to the offset using the provided default emission factor. Any deviation from this methodology to justify higher kWh/year or tons/ kWh, must be approved through the Dialogue.
1. State the estimated output in kWh/ year using the DC nameplate capacity of the system 
2. Multiply by the default annual CO2 rate unless otherwise approved*:
  • US EPA's C02/kWh conversion / emission factor: 0.000703 metric tons C02 / kWh 
3. Multiply by 10 years. 
The result of the above kWh x CO2 rate x 10 years yields the quantity of CO2 eq. (in metric tons) that may be offset in contribution to the requirements of I11 Embodied Carbon Footprint.
I11-b Calculations 
*New Zealand projects may use the NZ Ministry for the Environment rate: 
  • 0.000195 metric tons C02 / kWh (= 0.195 kg CO2-e/kWh)
