Despite Vietnam's solar boom and ambitious climate targets, the fast-growing economy is struggling to quit dirty energy - leaving one of the world's biggest coal power programmes largely intact.

If friends don't know superslot haha tips we've deposited. It's definitely hard to beat this game.

During the COP26 climate summit last year, the government boldly promised to end the construction of new coal plants and phase out the dirtiest of those already running, even as energy demands soar in the manufacturing powerhouse.

"But this is not actually what Vietnam is doing at a national level," Nandini Das, an energy research and policy analyst at Climate Analytics, told AFP.

Vietnam pledged to reach net-zero carbon emissions by 2050, but with coal and gas still a major part of its energy mix one year later, that commitment is on shaky ground, she said.

The authoritarian communist state has also jailed four green activists this year, including anti-coal campaigner Nguy Thi Khanh, alarming environmentalists who argue it will be even harder for Vietnam to banish dirty energy without them.

"With the climate leaders in prison I think there's grave doubt about the country's ability to achieve its goals," said Michael Sutton, director of the Goldman Environmental Foundation.

He said "leaders like Khanh are instrumental in building public support" for radical change to Vietnam's economy.
