Buildings Seen as Critical to Emissions Goals
The New Zealand Green Building Council says the Emissions Trading Scheme is missing a major opportunity to reduce New
Zealand’s emissions and the cost burden for New Zealand from the ETS.
In a discussion paper launched to coincide with World Green Building Day (23 September) New Zealand Green Building
Council CEO Jane Henley said the building industry can lead in the development of a low carbon economy and decrease the
need for offsetting strategies.
The paper calls for a range of complementary measures to be investigated to kick-start emissions reductions, given that
the ETS alone is insufficient to achieve the full carbon reduction potential within a short timeframe.
These measures include:
• ‘White certification schemes’ - incentivising investment in energy efficiency via white certificates that become
tradable assets.
• Green depreciation – accelerating depreciation allowances for building investments that involve specific energy
efficient fixtures and fittings, or that raise the overall energy performance of the building to a specific standard.
• Other regulatory measures – amending existing legislation such as the Resource Management Act, Building
Regulations and the Energy Efficiency and Conservation Act to encourage and facilitate reduced emissions from buildings.
Ms Henley said 17% of New Zealand carbon emissions are from the construction and operation of buildings. This is
particularly significant given that almost half (48%) of New Zealand’s emissions are from farming and 20% from
transport, both of which will be difficult to reduce.
Ms Henley said the built environment is also one of the few sectors where reducing emissions actually saves money rather
than costing the taxpayer.
“We can’t afford to ignore the opportunities offered by the built environment to reduce our country’s carbon emissions.”
A 2007 report by the Intergovernmental Panel on Climate Change (IPCC) projects that there is the potential by 2020 to
avoid at least 29% of the projected baseline global GHG emissions through cost effective mitigation measures in the
building sector, using existing technologies.
This supports the work of Sir Nicholas Stern in his 2006 report The Economics of Climate Change, where he also
identified the large scale of the opportunity that the built environment offers to reduce global emissions.
Opportunities for the built environment to offer deep carbon emissions reductions are unique. Cost abatement curves show
that emission reduction opportunities in the built environment are unmatched from a cost perspective.
