German Chancellor Angela Merkel vowed here Tuesday to press ahead for binding targets to combat global warming before the summit of Group of Eight (G8) nations.

"We need multilateral agreements to deal on a global basis with the challenges facing humanity," Merkel said after meeting visiting U.S. House Speaker Nancy Pelosi.

She said the United States was "moving a lot" on climate change, but made no reference to the differences threatening to abort a deal at the June 6-8 summit in the Baltic resort of Heilingendamm.

Pelosi urged for "global and sustainable solutions" to halt global warming, including making greater use of advanced technologies.

The United States will reportedly block a declaration on global warming at the summit as the George W. Bush administration opposes a proposal by Germany to curb greenhouse gas emissions to 50 percent below 1990 levels by the year 2020.

Germany, which takes the fight against climate change as one of its priorities during its G8 presidency, has vowed to fight to the end for a climate change declaration.

Merkel will make a last-minute effort by meeting Bush right before the summit opens on June 6.
