"Without the active partnership with the business community we are not going to achieve our goal," he said.
Mr Howard said a new report, to be released by the Australian Bureau of Agricultural and Resource Economics (ABARE), shows that by adopting cleaner technology, greenhouse gas emissions in the six nations taking part in the summit would fall by 20 percent by 2050.
The report show the spill-on effect would be a 13 percent cut in greenhouse gas emissions around the world, he said.
"On this basis the adoption of new technologies are therefore a credible and essential part of any suite of measures needed to reduce global emissions growth," he said.
Mr Howard said countries taking part in the summit have a responsibility to work towards not only reducing greenhouse emissions but also poverty, while at the same time maintaining economic growth.
"We have a responsibility to current and future generations to maintain that compatibility and I regard the partnership is playing a fundamentally important role in realising that goal."
Mr Howard said that the six nations in the partnership would hold their next meeting in 2007.
Delegates attending the summit focused on putting pressure on big business to adopt cleaner technologies to help reduce greenhouse gas emissions.
