* Nearly 200 nations attending climate talks in Germany
* Guterres calls for more carbon pricing, markets
* Says climate action will help, not hinder, economic growth

BONN, Germany, Nov 15 (Reuters) - Governments should put a price on carbon emissions to help combat global warming and stop making bad bets on fossil fuels, U.N. Secretary-General Antonio Guterres said on Wednesday at talks on a climate pact weakened by a U.S. pullout.
Guterres told almost 200 nations in Bonn, where they are working on details of the 2015 Paris climate agreement that aims to end the fossil fuel era this century, that a shift to cleaner energies would boost rather than hamper economic growth.
The Nov. 6-17 meeting is trying to bolster climate action after U.S. President Donald Trump, who doubts that man-made emissions are the main cause of rising temperatures, decided to withdraw and instead promote domestic fossil fuels.
Guterres urged governments to put a price on carbon to deter emissions and encouraged carbon trading as a way to restrict emissions. Last year, he said carbon pricing initiatives generated $22 billion.
"Growing carbon markets in Europe and North America, and China's expected announcement of one of the world's largest emissions trading systems, are a good sign," he said.
"But to meet the Paris goals we need at least 50 percent global coverage and a higher price on carbon to drive large-scale climate action," he said.
Some U.S. states have carbon trading even though there is no national market.
Guterres called on the Group of 20 biggest economies to lead.
Only 13 percent of global carbon dioxide emissions, mainly from burning fossil fuels, are subject to a price penalty, a global health study said last month in the Lancet medical journal.
It said the average global price was $8 a tonne, too low to drive changes that will both combat warming and restrict air pollution. Many energy companies and economists say a price of $40 or so would be needed to shift investments.
Guterres warned against gambling on fossil fuels, the main driver of rising temperatures that are causing more heat waves, floods, more powerful storms and species extinctions, according to mainstream scientific findings.
"In 2016, an estimated $825 billion were invested in fossil fuels and high-emissions sectors. We must stop making bets on an unsustainable future that will place savings and societies at risk," he said.
He said the Organization for Economic Cooperation and Development had estimated that climate policies could add one per cent to average economic output in the G20 countries by 2021.
"For years, many insisted that lowering emissions would stifle growth, and that high emissions were the unavoidable cost of progress," he said. "Today that dogma is dead." (Reporting By Alister Doyle)
