Q&A: What is China's carbon trading scheme?

  Q&A: What is China's carbon trading scheme? China Friday launched the world's biggest carbon trading system to help lower carbon emissions, but critics and analysts have raised doubts about whether it will have a significant impact. - China is drafting a new climate change law that environmentalists say might address some of the shortcomings in the current carbon trading system. Campaigners are also hoping that the current scheme gets rolled out across more industries, with stricter penalties."China... has set a long-term goal to be carbon neutral (but) the carbon market in its current form just isn't going to play much of a role in realising these ambitions," Myllyvirta said.

Keeping warm has become more expensive as coal-fire power outages take a toll on Australia's energy market.

Prices rebounded significantly between April and June because of outages and colder-than-average weather, the Australian Energy Market Operator says.

Wholesale electricity prices, or those paid by retailers before they supply to customers, averaged $95 per megawatt hour.

This compared with $37 per megawatt hour in the first three months of 2021.

The price hikes were driven largely by coal-fired power station outages.

Expert says massive green energy hub project in WA 'could power Australia'

  Expert says massive green energy hub project in WA 'could power Australia' If it goes ahead, the Western Green Energy Hub on the edge of the Great Australian Bight will be 20 times larger than the biggest renewable energy project in the world now.And WA's Hydrogen Minister Alannah MacTiernan says that, while it is early days, the Western Green Energy Hub plan holds the promise of a major opportunity for the state, and Australia, to develop a "more ambitious strategy" than producing and exporting iron ore and gas.

A turbine hall exploded at Queensland's Callide Power Station in May.

It tripped generators and transmission lines, leading to volatile prices in that state and NSW.

Meanwhile, flood damage at Victoria's Yallourn power station in June meant three units were taken offline for repairs.

Gas-powered generation provided backup for Callide and Yallourn, and prices went up for the east coast.

They averaged $8.20 a gigajoule for the April to June quarter, nearly double the price from the same period in 2020.

They also increased from an average of $6.03 a gigajoule between January and March this year.

Australia has the world's seventh-highest wholesale gas prices, according to the Institute for Energy Economics and Financial Analysis.

Colder-than-average weather across the eastern seaboard compounded price pressures, AEMO said.

National energy market demand for the second quarter rose by 250 megawatts compared to the same period in 2020.

This reversed a downward trend since 2018.

Perth had its coldest June in 31 years.

There was a 71 per cent rise in heating requirements compared to the second quarter of 2020.
