283,000 – FTE jobs sustained nationally

$12.5 billion – value of international freight and 16% of NZ total

$10.7 billion – the value airport adds to Auckland economy

153,900 – FTE jobs sustained in Auckland

25.1% – of region’s GDP

25.2% – of region’s employment

Auckland Airport Economic Impact Assessment was prepared by independent New Zealand based consultancy, Market Economics (2007)

climate change and sustainability
Climate Change and Sustainability

Operate in a safe, secure, sustainable and efficient manner

  • Sustainability is an integral part of our company vision “representing our country” and is inherent in our new branding.
  • Comprehensive five year sustainability action plan covering fourteen key areas of our environmental, social and economic performance.
  • First sustainability report FY07 included public disclosure of our carbon footprint.
  • Responded to the Carbon Disclosure Project 2007 and 2008.
the principles of carbon accounting
The Principles of Carbon Accounting

RELEVANCE Ensure inventory appropriately reflects the emissions of the company and serves the decision-making needs of users – both internal and external to the company.

COMPLETENESS Account for and report on all emission sources and activities within the chosen inventory boundary. Disclose and justify any specific exclusions.

CONSISTENCY Use consistent methodologies. Transparently document any changes to the data, inventory boundary, methods, or any other relevant factors in the time series.

TRANSPARENCY Address all relevant issues in a factual and coherent manner, based on a clear audit trail. Disclose any relevant assumptions and make appropriate references to the accounting and calculation methodologies and data sources used.

ACCURACY Ensure that the quantification of GHG emissions is neither under or overstated and that uncertainties are reduced as far as practicable. Achieve sufficient accuracy to enable users to make decisions with reasonable assurance as to the integrity of the reported information.

carbon accounting standards
Carbon Accounting Standards

Two standards available:

ISO14064-1 “Specification with guidance at the organizational level for quantification and reporting of greenhouse gas emissions and removals” 2006.

“Greenhouse Gas Protocol - A Corporate Accounting and Reporting Standard Revised” World Business Council for Sustainable Development (WBCSD) and World Resources Institute (WRI) 2007

carbon accounting methodology
Carbon Accounting Methodology

Setting Organizational Boundaries

Equity share approach

Under the equity share approach, a company accounts for GHG emissions from operations according to its share of equity in the operation.

Control approach

Under the control approach, a company accounts for 100 percent of the GHG emissions from operations over which it has control (financial or operational).

Setting Operational Boundaries

Have to be comprehensive with respect to:

Direct GHG emissions - emissions from sources that are owned or controlled by the company.

Indirect GHG emissions - emissions that are a consequence of the activities of the company but occur at sources owned or controlled by another company.

Carbon Accounting Methodology

Setting Operational Boundaries

Scope 1: Direct GHG emissions

Direct GHG emissions occur from sources that are owned or controlled by the company, for example, emissions from combustion in owned or controlled boilers, furnaces, vehicles.

Scope 2: Electricity indirect GHG emissions

Scope 2 accounts for GHG emissions from the generation of purchased electricityconsumed by the company. Purchased electricity is defined as electricity that is purchased or otherwise brought into the organizational boundary of the company. Scope 2 emissions physically occur at the facility where electricity is generated.

Scope 3: Other indirect GHG emissions

An optional reporting category that allows for the treatment of all other indirect emissions. Scope 3 emissions are a consequence of the activities of the company, but occur from sources not owned or controlled by the company. Some examples of scope 3 activities are extraction and production of purchased materials; transportation of purchased fuels; and use of sold products and services.

kpi targets carbon neutrality
KPI/Targets/Carbon Neutrality


  • Has to be based on emissions intensity to allow for growth:
      • CO2/pax
      • CO2/aircraft movement


  • Auckland Airport has a target of a 10% reduction in emissions per international passenger by 2012 (Adjusted FY06 base year).

Carbon Neutrality

  • Auckland Airport signed the ACI declaration on climate change in April 2008.
  • Working towards carbon neutrality.
  • Proceeding with caution (Inclusion/exclusion of scope 3 could be significant, NZ ETS, price of carbon, carbon neutral status of fuel and energy purchased).
drivers initiatives next steps
Drivers/Initiatives/Next Steps


  • Representing Our Country - a sustainable destination
  • Negative public perception of aviation/climate change and air travel potential negative impact
  • New Zealand Sustainable Tourism Strategy 2015
  • Company stakeholder expectations

Initiatives/Next Steps

  • GPU have been installed to allow airlines to switch off APU
  • CAT III lighting installed to ensure landings even in fog conditions (reducing diverts and fuel burn)
  • Operational efficiency improvements assisting with OTP
  • Work with Auckland Regional Transport Authority to further improve public transport to the airport
  • Development of our travel plan to improve surface access for employees and passengers.
drivers initiatives next steps16
Drivers/Initiatives/Next Steps

Initiatives/Next Steps

  • Pro-active energy conservation group
  • Energy audit underway and energy management plan that will be shared with retailers and tenants
  • Continue to produce annual profile
  • Continue to respond to CDP
  • Continue to investigate emissions from construction as an indicator for the sustainable development of airport infrastructure
  • Produce a whole of airport operations profile (including LTO emissions)
  • Put Auckland Airports’ profile in the context of “the whole airport operations”
  • An airport company with a 10,000 tonne profile may only contribute 5% of total emissions therefore whole of airport profile could be 200,000 tonnes p.a. - offsetting the 5% could be seen as greenwash.
  • Continue to investigate best practice and benchmarking.
