18 June 2010 – Investa has released its latest sustainability report,  with findings from seven years of data revealing the energy and greenhouse emissions of the group’s tenants.

The sustainability report, Investa’s eighth, is presented in a new online format with interactive graphs that allow the user to view performance and trend data for energy, emissions and water usage in each of Investa’s buildings.

Key environmental points from the report include:

  • Energy and Greenhouse emissions: An 11 per cent reduction in greenhouse gas emissions from operations within all businesses and facilities under Investa’s operational control.
  • Water: A 15.5 per cent reduction in Investa’s water footprint
  • NABERS Ratings: Of the 32 Investa properties rated during 2009, the weighted average NABERS Energy rating dropped from 3.89 to 3.73 stars. According to the report this was mainly due to a 62 per cent reduction in GreenPower purchases ahead of the introduction of Mandatory Disclosure.
  • Pollution and waste: In 2008, recycling rates dropped slightly to 66 per cent from 68 per cent and total waste collected (including recycled materials) reduced by 26.8 per cent
  • Materials use: 79 per cent of cut earthworks were reused on sites as fill.
  • Green Leases: Introduced in 2005, in 2007 Investa introduced a green lease schedule and guide to help tenants with the details of their sustainability requirements. Since then 100 per cent of tenants have moved into Investa buildings with the most advanced energy lighting and controls.
