The Howard Government initially negotiated favourable Kyoto Protocol targets for Australia (8% growth on 1990 levels) and Australia was estimated to have matched that target in 2007 at the close of the Howard Government's term.
Nevertheless, it elected not to sign the Treaty following the withdrawal of United States support for the process.
Howard argued that without the involvement of the United States and without binding emission reduction targets for the other large emitters in the developing world, in particular China and India, the Treaty would not be viable and could harm Australia's coal industry without effectively reducing global emissions.

[Ratifying Kyoto] could have damaged the comparative advantage this country enjoyed as a result of our abundance of fossil fuels and the importance of that abundance to Australia's export and general performance. [...]
I do not intend to preside over policy changes in this area that are going to rob Australia of her competitive advantage in the industries that are so important to us.

— John Howard, speech to the Business Council of Australia, 2006
On 6 June 2006, Howard announced a task force to conduct the "Uranium Mining, Processing, and Nuclear Energy Review", the terms of reference of which include "the extent to which nuclear energy will make a contribution to the reduction of global greenhouse gas emissions".

Howard announced on 10 December 2006 the formation of a Prime Ministerial Task Group on Emissions Trading.
On 3 February 2007, the Australian government announced that it could not by itself have a significant effect on mitigation of global warming, though it would continue to make efforts to cut greenhouse gases; it would be necessary for Australia to find means of adaptation.
On 4 June 2007, Howard reversed the decision and announced a new Carbon Trading Scheme to be in place in Australia by 2012.
The lengthy timeline was welcomed by investors, who were only asking for three years to plan for the scheme's introduction.

In July 2007, Howard announced in a video message on his website, a government plan to introduce a new "cap and trade" emissions trading system and a $627 million increase to spending on measures to tackle climate change.
The scheme was planned to enter into operation by 2011, however the policy could not be implemented following the Coalition's loss at the 2007 election.

At APEC 2007, Howard and other leaders signed the Sydney Declaration which saw developing countries officially agree, for the first time, on the need to set goals for cutting greenhouse gas emissions.
