New mercury convention could help fund climate efforts

Drive to cut toxic pollution from power plants likely to have knock-on effects for greenhouse gas emissions

By John Upton in Cancun

A global effort to bridle toxic mercury pollution could also slow down the upward creep of mercury levels in thermometers.

Coal-burning power plants are major sources of mercury pollution, which sicken people and wildlife. Those same power plants are also leading carbon dioxide polluters, making them leading targets of efforts to curb global warming.

It’s this confluence of opportunities – to reduce coal power plants’ mercury emissions while also cutting back on their carbon dioxide pollution – that has captured the attention of the Global Environment Facility.

The GEF administers pledges from wealthy nations under five conventions that support environmental projects in poorer ones. Those environmental conventions include one that deals with mercury and other toxic forms of pollution and another that deals with climate change.

The Minamata Convention on Mercury was finalized by 140 countries early last year. Many environmentalists were disappointed that the agreement won’t require binding caps on pollution levels.

One thing that the convention does require, though, is for developed countries to “promote and facilitate” the “development, transfer and diffusion” of technologies that help developing countries curb toxic pollution.

New finance

During meetings in Mexico this week, the GEF is considering how it will use $4.4 billion pledged during the past year by 30 wealthy countries – money that will be spent on environmental programs in more than 140 poorer ones over four years.

Those pledges include more than $1 billion for climate change programs and more than $100 million under the mercury convention.

And one of the group’s newest priorities is figuring out how to sink funds into projects that simultaneously meet the objectives of multiple environmental conventions.

“For example,” the GEF Secretariat and World Bank state in a 243-page report prepared in advance of this week’s meetings, “with the GEF as the financial mechanism of the Mercury and the Climate Change Conventions, there are opportunities to explore co-benefits of carbon and mercury emissions reduction at coal-fired power plants.”

Fernando Lugris, a Uruguayan ambassador who chaired the mercury convention’s negotiating committee, told RTCC that work is already underway to identify potential technologies that would need to be incorporated into new coal-burning power plants.

A technical committee has met once, he said, and it plans to meet three more times before producing its report.

“With the technology that we have nowadays, if you have the most advanced technology to capture mercury, then you’re going to be capturing many other things,” such as carbon dioxide, Lugris said.

“So we’re going to contribute a lot to the climate change issue as well.”

    This article is really puzzling to me. What upward creep of mercury levels in thermometers? I hope the writer is not referring to global warming causing a higher reading on the thermometer because the thermometer mercury level is unchanged as to quantity. Is the article telling us that thermometers are requiring more mercury now – what, are they making bigger diameter tubes? For what reason? And if you really want to undergo an exercise in futility, try to find a mercury thermometer from some supplier. About the only mercury thermometers left in this country are the super expensive standard thermometers which sell for several hundred dollars. I wanted to check my electronic thermometer but never found a reasonable, accurate mercury thermometer. They have not been available for several years.

    If Obama believes it, it must be wrong. Scientists are running from the IPCC and the US report on climate as fast as they can. Politicians came in and added lies and deleting facts. Only those researchers dependent on Obama money continue the lies and corruption. In the world order, it is the same. Some governments pay these researchers to lie like Obama does. News journalists love alarmism and lies. They help Obama spread lies and kill people. News journalists have now become the new Mafia! Soon, the people will start a revolt and news journalists will find it dangerous to walk on the street.
