The UK is in danger of building too many waste treatment plants and could reach over-capacity by 2015, new research warns.

A study from Eunomia Research & Consulting claims that if all of the facilities which have been granted planning consent are built and if waste arisings remain flat, then the country will have 5m tonnes more capacity than it requires.

The situation will be exacerbated if any plants which are currently in planning or unannounced are also built, or if waste arisings continue to fall, as they have for the past five years.

Talks between Iran and six world powers on its disputed nuclear program failed to produce a breakthrough on Thursday, in an apparent diplomatic setback for both sides.

The six wanted a freeze on Iranian production of uranium enriched to 20 percent purity, which is considered a short step from bomb grade. The Iranians wanted an easing of the onerous economic sanctions imposed by the West and recognition of what they call their right to enrich.

Hopes are fading that climate talks in Qatar late this year will make even modest progress towards getting a new globally binding climate deal signed by 2015, as preliminary negotiations in Germany this week have left much work to be done.

The fear is that if work plans and agendas are not set by the end of this year at the latest it could have a knock-on effect, holding up the entire effort to avert potentially devastating global warming.

China spurred a jump in global carbon dioxide (CO2) emissions to their highest ever recorded level in 2011, offsetting falls in the United States and Europe, the International Energy Agency (IEA) said on Thursday.

CO2 emissions rose by 3.2 percent last year to 31.6 billion metric tons (34.83 billion tons), preliminary estimates from the Paris-based IEA showed.

China, the world's biggest emitter of CO2, made the largest contribution to the global rise, its emissions increasing by 9.3 percent, the body said, driven mainly by higher coal use.

Germany has asked for discussion on deeper EU carbon emissions cuts to be put on the agenda at a meeting of environment ministers in June, EU sources said.

If agreed, a more ambitious target could help to spur the European Union's carbon market, which has sunk to record lows.

Previous debate of bigger carbon cuts, however, has been difficult, with coal-reliant Poland objecting that they could damage its economy.

Climate researchers said Thursday the planet could warm by more than 3.5 degrees Celsius, boosting the risk of drought, flood and rising seas. The UN's target is a 2 C limit on warming from pre-industrial levels for manageable climate change. In a report, scientists said Earth's average global temperature rise could exceed the dangerous 3.5 C warming they had flagged only six months ago.

A German development aid organisation said on Thursday it was in talks with the Indian government to dispose of 350 tonnes of toxic waste from the 1984 Bhopal gas disaster.

“We are in discussions with the Indian government,” a spokesman for the government-run Society for International Cooperation (GIZ) said, adding that Indian officials had approached Germany with the request.

No contract had been concluded yet, he said.

Details of the possible deal were unclear, but the GIZ would likely transport the toxic waste to Germany for treatment.

A yearly review of countries' greenhouse gas emissions cut pledges under an extension to the global climate pact the Kyoto Protocol could be a way to raise climate ambitions, the European Union's lead climate negotiator said on Wednesday.

Negotiators from over 180 countries are meeting in Bonn, Germany, until Friday to work towards getting a new global climate pact signed by 2015 and to ensure ambitious emissions cuts are made after the Kyoto Protocol expires at the end of this year.

Europe yesterday warned at climate talks in Bonn that efforts to forge a new global pact to avert environmental disaster were in danger of floundering, and some pointed fingers at China.

Nine days into talks meant to set the stage for a United Nations gathering in Qatar in December, where countries must adopt an amendment to the Kyoto Protocol on climate change, negotiators complained that procedural bickering was quashing progress hopes.
