Nuclear Weapon Free Zone (CANWFZ) established 20 years after President Karimov’s initiative

More news from Asia today.In what way do nuclear weapons affect our environmental aims? Perhaps we are all suffering from the results of previous testing. It remains to be seen exactly how important these moves towards a nuclear free world work out, after Chernobyl's disastrous aftermath and the possibilities of Fukushima's contamination of the Pacific.

What to do with CO2

What to do with CO2

The future is bleak, with vast fossil fuel emissions reducing very little. CCS seems always to be the excuse for energy companies to keep drilling, with government aid to help them store the global-warming emissions. As nuclear and renewable energies grow in importance, they still don’t seem capable of replacing fossils. As India’s new government under Nahendra Modi sets its sights on solar, perhaps we can see more large emitters becoming used to the idea of leaving the coal, oil and gas where it is.

Nuclear deserted?

Nuclear deserted?

The function of energy production is to supply electricity to industry. With some reduction in power needs, many countries are adapting their green policies in various ways. The use of nuclear power was declining, then it began to grow, with hope of alternative nuclear fuels and breeder reactors whose waste could be recycled. This avoids the awesome prospect of getting rid of the radioactivity that can last for hundreds of thousands of years.
