Deep-sea mining: A new gold rush or environmental disaster?
In the depths of the Pacific Ocean between Mexico and Hawaii, trillions of potato-shaped rocks scattered across the seabed contain minerals such as nickel, cobalt and manganese that are vital for green technologies in the global energy transition.
In this region – the Clarion-Clipperton Zone (CCZ) – an abundance of the rocks, known as polymetallic nodules, is fuelling debate about the mining of metals needed to produce technology such as batteries for electric vehicles.
Environmentalists say deep-sea mining could cause critical damage to ecosystems that scientists know little about, yet mining companies argue that it is better for the environment than land-based extraction.
More than a dozen nations have sponsored small-scale exploration projects, but commercial mining of international waters is not permitted. That ban will be debated at a UN meeting in Jamaica beginning this week.
Gerard Barron, CEO of The Metals Company, which is leading efforts to scoop up the nodules thousands of metres underwater, said mining the ocean does less damage to nature than extraction in places like the Indonesian rainforest.
“Our oceans are full of metals,” Barron said in an interview.
India targets net-zero carbon emissions by 2070, says Modi
India’s economy will become carbon neutral by the year 2070, the country’s prime minster has announced at the COP26 climate crisis summit in Glasgow. The target date is two decades beyond what scientists say is needed to avert catastrophic climate impacts. India is the last of the world’s major carbon polluters to announce a net-zero target, with China saying it would reach that goal in 2060, and the United States and the European Union aiming for 2050.
COP26: What climate summit means for one woman in Bangladesh
China's carbon emissions are vast and growing, dwarfing those of other countries. Experts agree that without big reductions in China's emissions, the world cannot win the fight against climate change. In 2020, China's President Xi Jinping said his country would aim for its emissions to reach their highest point before 2030 and for carbon neutrality before 2060. His statement has now been confirmed as China's official position ahead of the COP26 global climate summit in Glasgow. But China has not said exactly how these goals will be achieved.

Deliver on promises, developing world tells rich at climate talks
A crucial U.N. conference heard calls on its first day for the world's major economies to keep their promises of financial help to address the climate crisis, while big polluters India and Brazil made new commitments to cut emissions. World leaders, environmental experts and activists all pleaded for decisive action to halt the global warming which threatens the future of the planet at the start of the two-week COP26 summit in the Scottish city of Glasgow on Monday. The task facing negotiators was made even more daunting by the failure of the Group of 20 major industrial nations to agree ambitious new commitments at the weekend.
