The OECD today confirmed its forecast of weak economic growth in Europe next year, while most of the other major world economies would see stable output.
According to the latest edition of its composite leading indicators (CLIs), the data "continues to point to a loss of growth momentum, with stronger signals of a slowdown in the case of Germany and Italy," the OECD said.
In France, however, the CLI - designed to anticipate turning points in economic activity - suggests a stable growth momentum.
In the UK "stable growth may ease, albeit from relatively high levels", the Paris-based Organisation for Economic Cooperation and Development, which provides economic analysis and advice to its industrialised country members said.
Among the countries anticipating stable growth in 2015 were Canada, the US, Brazil, China and Russia, according to the OECD.
The CLI for Japan points to "growth losing traction, though this may be related to one-off factors," the OECD said.
The only major economy where the CLI shows a pick-up in growth momentum is India, it added.
World can't afford European economic 'lost decade' - US
The US urged European governments to do more to stoke growth, warning that monetary easing by the European Central Bank is not enough to avoid a deeper slump.
"The world cannot afford a European lost decade," US Treasury Secretary Jacob Lew said, criticising "status quo policies" in the continent.
"The ECB has taken forceful steps to support the economy through accommodative monetary policy," Lew said.
"But as recent economic performance suggests, this alone has not proven sufficient to restore healthy growth. Resolute action by national authorities and other European bodies is needed to reduce the risk that the region could fall into a deeper slump."
Lew added that the world is relying too much on the US to drive a global economic recovery.
"The global economy cannot prosper broadly relying on the US to be the importer of first and last resort, nor can it rely on the US to grow fast enough to make up for weak growth in major world economies," he said.
Lew's comments came ahead of the meeting of G20 leaders in Brisbane, Australia this weekend. Sluggish global growth and backsliding by the euro zone economy are expected to be key topics in the summit.
