Internal Operations

Investa’s internal operations are immaterial compared with the environmental impact of managing our property assets. However, these impacts are significant when compared to the consumption impact of the ‘world average person’. In response to this fact, to reap potential savings, and to encourage a sustainability culture in the business, we report on the impact of our internal operations in several key areas.

Travel

Staff air travel produces a significant environmental impact and also a considerable cost to the company both in terms of expenditure and staff time.

On a mileage / intensity basis, Investa’s emissions from air travel have reduced 76 percent per staff member since 2004/05. Our staff numbers more than doubled with the acquisition of Clarendon in 2005 but our total distance flown and therefore our greenhouse gas emissions from air travel decreased significantly last year.

While we have calculated our emissions based on 166g.CO2-e/person/km sourced from the Department of Climate Change (DCC), Climate Friendly calculated our emissions intensity to be 0.76 Tonnes CO2-e per person. Their calculations are based on in-house algorithms and factors from the International Panel on Climate Change and the Greenhouse Gas Protocol which take into account not only carbon emissions, but also the other effects of flying that contribute to global warming, such as nitrogen oxides that convert to ozone at high altitude, contrails, and ice clouds. They note that the global warming impact of air travel is approximately 2.7 times that of fuel alone.

While our expenditure on LPG for Clarendon’s staff fleet increased significantly over the period, so did the LPG price. The price of LPG for period was estimated to be 69.6c/L (based on figures (references, and here) from the Department of Resources, Energy and Tourism) compared with 51c/L in 2007. Analysis shows therefore little change since the last report, but a 13% decrease since 2006/07. Similarly taxi expenditure increased significantly in the reporting period compared with the previous reporting year but kilometers and therefore emissions only increased 0.01Tonnes/person.

  • 1. Based on an average price of 51¢/L and a fuel efficiency of 0.176L/km (using DCC figures) and 1.6tonnes CO2-e/kL for LPG (also from the DCC)
  • 2. Based on an average price of 69.6¢/L and a fuel efficiency of 0.176L/km (using DCC figures) and 1.6tonnes CO2-e/kL for LPG (also from the DCC)
  • [NB, Fleet relates to Clarendon exclusively.]

  • 1. The actual number of trips is not available but based on the spend at a kilometre rate of $1.68 plus the flag fall of $2.90 and using 0.176L/km and 1.6tonnes CO2-e/kL for LPG (DCC figures).
  • 2. The actual number of trips is not available but based on the spend at a kilometre rate of $1.85 plus the flag fall of $3.10 and using 0.176L/km and 1.6tonnes CO2-e/kL for LPG (DCC figures).

Office stationery

During the reporting period, paper use increased dramatically. In part this was due to the re-launch of the Clarendon business in Victoria. However, due to improvements in purchasing arrangements, the number of writing instruments purchased for each staff member dramatically reduced. The number of toner cartridges used reduced significantly due to the purchase and operation of new, more efficient multi-function devices across the business.
