Prime Minister Julia Gillard is pleased with an APEC leaders' agreement to slash the region's energy intensity and cut tariffs on environmental products.

Ms Gillard was in Hawaii on Sunday (local time) with US President Barack Obama and the leaders of 19 other nations for the annual Asia-Pacific Economic Cooperation (APEC) summit.

The leaders agreed to a non-binding target to reduce the region's high energy intensity, which measures the energy efficiency of national economies, by 45 per cent of 2005 levels by 2035.

"That means the whole region will collaborate to reduce energy intensity," Ms Gillard told Australian reporters shortly after the meeting ended.

"The setting of this ambitious goal is an important outcome.

"APEC is setting an example to the world on green energy and green growth."

The leaders also agreed to cut tariffs on environmental goods to five per cent.

That means Australian companies will be able to get their products - such as solar panels and fuel cells - to regional markets at lower prices.

"This is unambiguously good news for Australia," Ms Gillard said.

"We do not have tariffs of more than 5 per cent on any environmental good.

"What that means is that we will not experience any of the pain that will come from those tariff reductions."

The leaders also chose to endorse Australia's position that the stalled Doha round of global trade liberalisation talks be broken into smaller events.

They also called on European leaders to do more to address the eurozone debt crisis.

Ms Gillard is due to leave Hawaii later on Sunday.
