was key in highlighting the environmental and social impacts of the Ok Tedi mine in Papua New Guinea. The 1990s were the decade in which greenhouse pollution and climate change became critical issues. ACF helped to establish the Sustainable Energy Industries Council of Australia and the Federal government agreed to cut greenhouse gas emissions by 20% by the year 2005. When Canberra backtracked on this commitment in the mid-1990s, ACF spoke out in international forums including the 1995 Berlin Climate Change Conference. In 1995 ACF launched its first website with a view to facilitating more frequent and effective communication with its diverse range of supporters. ACF worked to bring the degraded state of the Murray-Darling Basin to public attention. In 1996 ACF introduced the concept of environmental flows into the political arena and launched a major campaign to reverse the decline of Australia's rivers. ACF and other environment groups worked with the Mirrar people to halt the Jabiluka uranium mine at Kakadu. The 1998 blockade gained significant media attention and placed Jabiluka on the national and international agenda. 21st century In 2000 ACF's Natural Advantage: A Blueprint for a Sustainable Australia was launched by Sir William Deane, then Governor General of Australia. The blueprint outlined ACF's vision for a sustainable Australia and set out inspirational and long-term solutions to environmental problems. Some of the key initiatives of the blueprint were a national project of sustainability reform; a long-term, strategic commitment to land and water repair; greenhouse gas reductions and energy efficiency; environmental tax reform; reconciliation between Indigenous and non-Indigenous Australians; and building social capital to ensure all Australians benefit from their great natural advantages. In the early years of the new millennium ACF 'walked the talk' and moved its head office to the 60L Green Building in Carlton. ACF's supporter base grew and many more Australians expressed a desire to make a difference for the environment. Polls regularly placed the environment among Australians' top concerns. ACF has entered into a range of partnerships with Indigenous Australians, particularly in Northern Australia, with the scientific and business sector and with rural communities. ACF is developing a national community outreach program to inspire individual action on some of the most pressing environmental challenges Australians face. ACF's achievements for the decade of 2000–2010 include the restoration of flows to the Snowy River, the banning of radioactive waste dumps in SA, a halt to broadscale
