Environmental management report
Royal Botanic Gardens
The Royal Botanic Gardens and Domain ‘Every Drop Counts’ water efficiency rating showed a 21 per cent reduction in potable water use. Although below average rainfall for November through to March resulted in a 16 per cent increase in total water usage compared to last year, there has been a total reduction of 37 per cent since benchmarking in 2000-01.
Additional water savings initiatives included careful planting, mulching, watering only high-use lawns, and installing rainwater tanks at some display gardens.
Mount Annan Botanic Garden
Energetics (for Sydney Water) awarded Mount Annan Botanic Garden a fourstar rating for water use; the first NSW government agency to achieve this level.
Last year, monitoring meters identified that one third of annual irrigation water flow was lost through leaks and pipe breaks. A pipeline replacement program resulted in 62 per cent water saving in 2007-08.
Mount Tomah Botanic Garden
Mount Tomah uses 100 per cent nonpotable water for irrigation and facilities management. Water is sourced from local dams, creeks and rainwater tanks. Following treatment, this water is also used to supply public facilities.
Energy consumption and CO2 emissions
The Trust completed the DECC Sustainability Management Diagnostic in March and received a two-star rating (2.9 of 5.0) - the highest result any organisation has received to date. An action plan and data analysis section will be completed by the Trust next year.
The Trust reduced its total electricity consumption by 29 per cent, despite increased numbers of events, especially at Mount Annan and Mount Tomah. The Royal Botanic Gardens and Domain also reduced its gas consumption by 43 per cent. The Trust continues to use six per cent GreenPower across the organisation and all events in the Domain’s Phillip Precinct now use 100 per cent GreenPower.
Overall, the Trust has reduced its CO2 emissions by 30 per cent since 2007-08, and by six per cent since benchmarking in 2002-03.
