Finance ministers and officials from 15 different countries have met in the Polish capital Warsaw to discuss the economic downturn.
At the same time in Poznan, Poland, representatives from almost 200 countries are meeting to for the UN Climate Change Conference to discuss a replacement for the Kyoto Protocol.
Achim Steiner, executive director of the UN Environment Programme (UNEP), said the two issues are inextricably linked.
He said: "Combating climate change is the stimulus package needed to power the planet out of its current malaise and set the stage for a 21st century green economy - one that prizes resource efficiency, innovation and decent employment in developed and developing societies alike."
A survey for UNEP, the World Bank and the International Union for Conservation of Nature (IUCN) of 1,000 experts from 115 countries found three-quarters thought economic recovery and climate change went hand in hand.
