PRAGUE, May 27 (Reuters) - The Czech Republic could sell up to 100 million tonnes of surplus greenhouse gas emissions rights under the UN-run Kyoto Protocol, and talks are underway to sell a portion to Japan, a government official said on Tuesday.
A large part of the quota may be offered in an auction later this year.
Kyoto binds some 37 industrialised nations to limits on their greenhouse gas emissions between 2008 and 2012, but allows countries which undercut their caps to sell that unused quota to other states busting theirs.
European, former communist countries like the Czech Republic are well within their targets to cut emissions by 8 percent compared to 1990 levels, because of the collapse of their smokestack industries -- and carbon emissions -- in the 1990s.
The Czechs have a surplus of 150 million credits, out of which they could sell around 100 million for a total of at least 1 billion euros ($1.58 billion), Pavel Zamyslicky from the Environment Ministry's climate change department told Reuters.
The credits, known as Assigned Amount Units (AAUs), are sold under the Kyoto Protocol scheme, aimed at cutting emissions of the greenhouse gases blamed for global warming.

Zamyslicky said Japan could buy around 10-20 percent of the whole amount of credits for sale. The two countries should sign a memorandum of understanding in the coming days, agreeing on further negotiations.
He said the price was yet to be negotiated, but it should exceed 10 euros per credit allowing one tonne of carbon dioxide emissions.
"We have several potential buyers and Japan is the most serious one," Zamyslicky said in a telephone interview.
"Ideally some credits could be sold at the turn of the year," he added.
A source told Reuters last week Japan was also in talks with Russia and Poland, after signing a memorandum with Hungary.
Trades in AAUs has been limited so far by criticism that such deals have nothing to do with funding extra emissions cuts, the main aim of the Kyoto pact, and have been dubbed "hot air" by environmental groups.
The Czech government says it wants to use the proceeds for environmental projects such as power production from renewable sources.
Zamyslicky said the Czechs were in talks with other buyers such as Finland, Spain, Netherlands and some private companies interested in buying the unused emissions rights.
The ministry is also considering auctioning part of the 100 million surplus credits in the autumn, he said, but gave no details.
The remaining 50 million surplus allowances has to be kept as a reserve and for other environmental projects. Czechs have the fifth biggest surplus of carbon credits after Ukraine, Russia, Romania and Bulgaria.
By buying AAUs, countries with higher emissions than their Kyoto targets can avoid the cost of reducing emissions at home.
