              {`The Calculator is calibrated to regional greenhouse gas inventories produced for the 2012/13 and 2014/15 financial years. These inventories estimated the region’s greenhouse gas emissions in line with international emissions reporting guidelines. Emissions were calculated from a range of measured activity data (such as electricity consumption, fuel sales and livestock numbers) and estimates. The Calculator draws on these same data alongside a wide range of complementary data sources. Results align with the inventory estimates except where there are differences in accounting methods (such as forestry accounting rules) or updates to underlying data sources.
  
              For energy and road transport emissions, the inventories only provide data at an aggregated level (i.e. total consumption of electricity, natural gas, petrol and diesel). Where necessary, we have used other data sources and assumptions to disaggregate the inventory data into segments (such as household energy use and light vehicle transport). These disaggregated estimates are less reliable and should be treated as indicative.`}

              In some sectors (such as agriculture, forestry and waste), robust data are available for individual TAs. In other sectors (such as energy and transport) sub-regional data are not available or are subject to problems such as boundary issues. For these sectors, TA level emissions estimates are therefore more reliant on assumptions. For example, household and commercial energy demand are assumed proportional to the TA’s share of regional population and employment respectively.
  
              Future changes were largely assumed to be uniform across the TAs – such as travel patterns, electric vehicle uptake and household energy use. Exceptions to this include land use change, where regional changes were allocated according to current land use patterns, and landfill gas capture, where each landfill was considered separately.`}

              {`The Calculator is designed for exploring a range of plausible future pathways depending on choices and developments that happen over the next 30 years. Most levers can be varied between Level 1, representing the potential change in that variable with no effort to reduce emissions, and Level 4, representing the potential change with maximum effort to reduce emissions. Some levers can be adjusted between Levels 1 to 3 or 4, representing different choices that are not necessarily related to efforts to reduce emissions.
  
              Where possible, the lever assumptions have been set based on published reports and projections from credible New Zealand sources such as government agencies and research institutes. However, in many cases such data were either unavailable or outdated. In these cases, assumptions were set by informed judgement based on analysis of historical trends and underlying drivers. A list of data and information sources used is provided below. The evidence base on emissions reduction options for New Zealand is evolving rapidly, and several new pieces of analysis have been published since this version of the Calculator model was completed (for example, `}
