This publication presents information on greenhouse gas emissions from the energy sector in New Zealand for the calendar years 1990– 2011.
Energy sector emissions are responsible for slightly less than half of New Zealand’s total gross emissions. Total gross emissions exclude emission reductions from land use change and forestry.
The remainder is primarily from agriculture. Emissions are presented as the carbon dioxide equivalent (CO2-e) of the direct greenhouse gases – carbon dioxide, methane and nitrous oxide – based on their global warming potential (see Technical Notes on back page). This publication updates the annual series and includes revised numbers for 1990–2010 where improved data or methodologies have been applied.
