CDU achievements

In 2020 the Times Higher Education (THE) University Impact Rankings positioned CDU 99th in the world out of 768 Universities across 85 countries for our social and economic impact based on the United Nations’ Sustainable Development Goals.

This outstanding result was driven by the substantial work undertaken by CDU staff in the areas of Outstanding Education, Gender Equality, Good Health and Wellbeing, and Partnerships for the Goals.

Awards

  • The Envirocollective won the Environment and Conservation Award at the 2020 NT Natural Resource Management Awards night for their long-running Conservation on Campus project.

    Activities have included:

    • cane toad management
    • feral cat education events and actively campaigned for greater campus feral animal management
    • native plant identification walk and promotion of planting native species with a focus on why they are important to the local Endangered Black Footed Tree Rat
    • Gamba Grass eradication
    • campaigning for a student representative on the CDU Student Council and on the CDU Sustainability Leadership Group
    • engagement with external stakeholders such as Darwin Wildlife Sanctuary, Birdlife Top End, City of Darwin, Climate for Change, Inspired NT, Power and Water Living Water Smart, Territory NRM, Friends of Casuarina Coastal Reserve and local experts.
    • engagement with internal stakeholders such as Northern Institute Aboriginal Cosmology researchers, Research Institute of Environment and Livelihoods researchers, and CDU Facilities Management.
  • The Creating Impact category recognises institutions that have achieved significant sustainability-related outcomes, on-campus or within their community, using minimal and/or limited resources. Initiatives need to demonstrate the relationship/link between the number of resources used (for example staffing, budget, time) and the level of impact achieved (for example quantifiable changes in behaviours and/or reportable metrics). Initiatives could include: those which can demonstrate significant sustainability achievements (such as sustainable products, processes or learnings) in a relatively short period and/or with a restricted budget, and/or with a small staff base e.g. good progress from a low base. Projects that raise the broader profile of sustainability will be particularly favoured.

    Applications must show how learning from others has been implemented and for the greater chance of success go beyond legal compliance. Initiatives can cover a single aspect of sustainability or have multiple foci, including but not limited to: facilities & operations; learning & teaching, research; leadership and governance; community; procurement, and; engagement. However, regardless of the topical focus, the primary aim of this category is to demonstrate how institutions can still achieve creative and high impact outcomes with limited resources.

    CDU has been shortlisted for its application Guerrilla Gardening

    How the cultivation of mutually beneficial relationships has enabled CDU’s Facilities Management to achieve targets without a ratified Sustainability Plan.

    CDU started its journey towards sustainability in 2013 by developing, through engagement with staff and students, a draft CDU Sustainability Plan.

    Facilities Management, in anticipation of ratification of the plan, seized opportunities to improve its sustainable practices and this has resulted in significant sustainability improvements across a number of areas, many of which could not have been achieved without the assistance of the staff and students in other fields.

      The following information is part of a larger application providing financial, social and student impact.

       

      SDG 7: Affordable and Clean Energy

      Energy targets: Increase use of renewable energy to at least 10% of all NT campus energy requirements by 2020; Reduce overall non-renewable energy use at NT campuses by 2020 by at least 5% compared with 2016.

      • CDU has reduced its energy use by 11% since 2015 across 6 campuses/centres.
      • CDU has 3% renewable energy use compared with total requirements. (In 2017 this was the 3rd highest of any University in Australia (2017 TEFMA)).
      • LED lighting installed across Sydney campus and new buildings. Replacements with LED elsewhere with large-scale replacement proposed.
      • Working with Engineering students and staff to improve HVAC efficiency and heat mitigation on our campuses.
      • Working with the Centre for Renewable Energy to increase CDU's campus generated renewable energy.

      SDG 15: Life on Land

      Biodiversity targets: Increase carbon sequestration on CDU properties through planting; All biodiversity conservation areas on CDU campuses are identified and appropriately managed by 2020.

      • 3000 native trees planted during 2017 - 2019 through working with Conservation and Land Management lecturers and students, Greening Australia and Conservation Volunteers.
      • Biodiversity survey scoped with Environment staff and other environmental advice provided by staff and students.
      • Provision of possum boxes by Facilities Management working with an Environment research student.
      • Undertaking regular toad busts, weed and pest management. Toad busts were initially conducted by Conservation Volunteers and have been recently undertaken by Conservation and Land Management students. They will be undertaken for the bulk of the coming year by the Envirocollective.
      • Creation of flood mitigation drains and berms, removal of substantial areas of the weed 'coffee bush' by working with Civil Construction lecturers and students.

      SDG 11: Sustainable Cities and Communities

      Recycling and waste minimisation target: Reduce the total volume of CDU waste to landfill in 2020 by 20% compared to 2015.

      • 29% combined decrease 2015 – 2019 in waste-to-landfill on Casuarina, Palmerston and Waterfront campuses
      • Removed emptying of desk bins from cleaning contract and improved waste stream reporting. Simultaneously undertook change management communications and actions to aid implementation including the introduction of “Recycling Champions”.
      • Waste from food preparation from both CDU food retailers is sent to the Lakeside Drive Community Garden (on CDU leased land) for compost. This had led to other retailers from surrounding areas approaching the LDCG to learn how to undertake their own composting.
      • CDU has also supported fundraising for community groups using the Cash for Containers scheme, eg Down Syndrome Association of the Northern Territory, and supported the FM staff-led: ‘Too Much Stuff’, Darwin’s only upcycling, recycling Flea Market.

      SDG 6: Clean Water and Sanitation

      Water target: By 2020 reduce overall water consumption by 20% compared with 2015.

      • Water consumption decreases 2015 – 2018: Casuarina Campus 13%, Palmerston Campus 26% (Irrigation bore water decrease 36%) and Waterfront Campus 12%.
      • The 2017 Water Management Plan developed by Living Water Smart (Power and Water) suggested various changes including smart controller irrigation systems, water-saving devices and better water management which have been implemented.

      Top three learnings:

      1. We made a start internally on almost all of our sustainability initiatives, no matter how small, as a basis to build interest and momentum as we went along. 
      2. We engaged early with our organisational community to build commitment and buy-in to our sustainability initiatives.
      3. We developed mutually beneficial sustainable goals with members of our organisational community.

    1. Lakeside Drive Community Garden was started by CDU students over 10 years ago. It is a holistic, productive and sustainable garden that incorporates natural habitats and ecosystems. It provides regular workshops and community events focus on sustainable living, sharing skills, knowledge and building a stronger community. It is located on CDU leased land and a variety of support is provided to the garden by CDU. 

    2. TOO MUCH STUFF is a CDU supported event - Darwin's only upcycling, recycling flea market - held on CDU grounds once a month. TOO MUCH STUFF was nominated in the Sustainable Enterprise Award category. It was co-founded by CDU's Facilities Help Desk Coordinator Esther Lloyd-Taylor who has received the following accolades for her efforts in promoting sustainable practices: 

      • Nominated 2020 Northern Territory Community Achievement Awards
      • Nominated 2020 NT Volunteer of the Year Awards
      • Nominated in 2020 Australian of the Year Awards
      • Shortlisted in 2019 Local Hero Australian of the Year Awards
      • Winner 2018 Ryan Family Award.
    3. The $30 million complex was ‘officially’ opened at the Charles Darwin University Casuarina Campus on 26 April 2012, by the then Prime Minister Ms Julia Gillard.

      In 2014 Charles Darwin University was recognised for championing sustainable building practices in the Northern Territory.
      The university received a nationally recognised Green Star rating for the iconic Blue 2 Indigenous Leadership precinct on Casuarina campus.
      The sophisticated facility received a 4 Green Star Education Design v1 certified rating from the Green Building Council of Australia for its environmentally sustainable building practices.

      The building’s design featured superior sustainable technologies, such as set-point air-conditioning and motion triggered, low energy lighting.

      Water captured from the building’s air-conditioning system is reused in the outdoor ponds, waterfall and garden, and recycled rainwater is reused in the building’s toilet facility and garden.

      The building’s physical placement takes advantage of the surrounding environment and shields it from the western sun. Bamboo flooring, environmentally friendly paint, sustainable furniture and carpet are used throughout the facility.

      In 2018, the redesign of the Ceremonial Space won the Yali McNamara Award at the Australian Institute of Architects NT Awards.

      The redesign project consists of a new ceremonial space, seating and woven shading structures which dramatically improve the usability and experience of this important cultural meeting place. Individual elements take inspiration from the surrounding cultural, natural and built environments. The careful use of colour, material and built form was significant to create harmony with and enhance the comfort of the ceremony space, providing a culturally relevant and vibrant space for the community.

      The complex has awesome environmental credentials and minimizes its carbon footprint by;

      • capturing run-off and condensate, and recycling this water in appropriate ways throughout the complex, for the flushing of toilets and the like;
      • reducing power costs and keeping the use of electricity to a minimum, by automating lighting to all rooms with “daylight harvesting”;
      • maximising airflow and use of natural light in all areas possible;
      • using “green” star-rated furniture, furnishings and materials throughout the complex;
      • and, recycling and composting of waste, amongst other things.

    CDU sustainability by campus location

    • CDU is making sustained efforts to have more sustainable campuses. However fluctuations in results should be viewed in the context of the natural environment. Biodiviersity has natural cycles and water and energy use fluctuate greatly depending on the humidity, rainfall and temperature. Climate summaries for each year are found on the Bureau of Meterology site. 

      Energy

      Target: Reduce overall non-renewable energy use at NT campuses by 2020 by at least 5% compared with 2016.

      Result: Reduction of 13.8% between 2016 - 2019.

      Data includes Casuarina, Palmerston, Alice Springs, Waterfront, Sydney and Katherine Rural College Campuses.

      Recycling and Waste Minimisation

      Property and Facilities Services has reviewed and improved our procedures for managing and quantifying CDU's waste, and as a result, our 2019 figures do not conform to previous year's metrics. We will be establishing a new baseline in 2020.

      Target: Reduce total volume of CDU waste to landfill in 2020 by 20% compared to 2015.

      Result: 29% reduction in waste to landfill 2015 - 2018

      Recycling and waste minimisation has only been implemented on Casuarina, Palmerston and Waterfront campuses.
