  5. 5. Foreword The 007 Lowy Institute Poll found that tackling climate change is as important to Australians as improving standards in education - and more so than improving the delivery of health care, ensuring economic growth and fighting international terrorism. This Report is a first attempt at a nationwide quantification of the carbon savings and financial benefits resulting from using telecommunications networks to conserve energy and increase clean energy use at home, in the workplace and in ways we connect people, enterprises and communities. The analysis presented in this report finds that the telecommunications sector is uniquely placed to provide important services that can yield nationally significant reductions in greenhouse gas emissions. Indeed a key finding is that many of the telecommunication solutions for living and working in a future carbon-constrained world can actually lead to cost savings for business and the consumer. There is scant information in the public domain that quantifies the opportunities presented by telecommunications to reduce greenhouse gas emissions. This report does. This report is not the last word on telecommunications and carbon emissions, but one of the first. We welcome a robust public dialogue around the ideas presented in the report – including critiques by national and international specialists who may provide more detailed insights and more refined ideas. Climate Risk, the authors of the report, and Telstra are committed to raising the level of public discourse and to capture and share learning that can result. This dialogue will, we hope, lead to a more comprehensive understanding of how we can work together to achieve the benefits of a high bandwidth, low carbon society. Time is of the essence as we find innovative solutions to reducing carbon emissions. We are delighted to offer this study into the marketplace of ideas and we invite you to share your reactions, insights and ideas with us and with each other through forums, the media and private discussions.
