At Durban, a year ago, there was the unexpected, but welcome, agreement to begin negotiations on a new legally binding instrument involving all major emitters of greenhouse gases, to be finalised by 2015, and to take effect in 2020.
Almost 30 countries are considering or planning to introduce nuclear energy as interest remains strong despite last year's Fukushima accident, the United Nations' atomic agency said.
Japan's Fukushima nuclear crisis was a preventable disaster resulting from collusion among the government, regulators and the plant operator, an expert panel said, wrapping up an inquiry into the worst nuclear accident in 25 years.
Since Fukushima, important developments have taken place. Germany has decided to shut down its fission plants. Moreover, in a referendum, 95% of the Italian public opposed plans to restart a nuclear programme in the country.
Efforts have resumed at Japan's Fukushima Daiichi nuclear power plant to restore electrical power and cool its overheated reactors, seriously damaged by the 11 March earthquake.
The United Nations nuclear agency, IAEA, says there have been positive developments in Japan's efforts to tackle a nuclear emergency after the 11 February quake.
Engineers at Japan's stricken Fukushima nuclear power plant have managed to lay a cable to reactor 2, the UN's nuclear watchdog reports. Restoring power should enable engineers to restart the pumps which send coolant over the reactor.
As concerns about a meltdown at the Fukushima plant escalate, Britain’s the Telegraph revealed a series of two-year-old cables the paper obtained from Wikileaks that show unnamed experts telling Japanese officials they needed to update their nuclear safety protocols.
The risk of the contamination of food products from nuclear radiation in Japan is limited to the specific area surrounding the damaged nuclear plant, according to a source from the World Health Organization (WHO).
