California Carbon Allowance (CCA) prices saw steep declines on Wednesday following steady selling over the first half of this week, bucking the trend of significant daily increases to start the past few months.

Technology and engineering academy tells government not to wait for a ‘miracle’ and aim for net zero emissions now

Australia’s leading scientists and engineers have told the Morrison government the technologies needed to make significant cuts in greenhouse gas emissions already exist – and the Coalition should immediately implement a national net zero policy.

In an explicit response to the government’s “technology, not taxes” approach to reducing emissions, the Australian Academy of Technology and Engineering has released a position statement calling on the government to “prioritise the immediate deployment of existing mature, low-carbon technologies which can make deep cuts to high-emitting sectors before 2030”.

Extinction Rebellion members march through Westminster and target offices of JP Morgan

An occupation of the offices of the environmental group WWF by a protest in solidarity with indigenous people in Africa has continued into its second day, as Extinction Rebellion’s actions continued in London on a smaller scale.

About a dozen activists organised under the banner WTF WWF occupied the WWF offices in Woking, Surrey, on Tuesday morning. They stayed overnight, refusing to leave until it begins a dialogue with indigenous communities in Tanzania, Kenya and Cameroon who say they are being displaced by conservation efforts.

Swiss scientists develop prototype ‘nanogenerator’ that produces renewable energy when trodden on

Scientists have developed technology that can turn footsteps into electricity.

By tapping into an unexpected energy source, wooden flooring, researchers from Switzerland have developed an energy-harvesting device that uses wood with a combination of a silicone coating and embedded nanocrystals to produce enough energy to power LED lightbulbs and small electronics.

Iraqi minister and International Energy Agency chief urge countries to move away from fossil fuel dependency

• Without help for oil-producing countries, net zero by 2050 is a distant dream

The finance minister of Iraq, one of the founding members of the global oil cartel Opec, has made an unprecedented call to fellow oil producers to move away from fossil fuel dependency and into renewable energy, ahead of a key Opec meeting.

Ali Allawi, who is also the deputy prime minister of Iraq, has written in the Guardian to urge oil producers to pursue “an economic renewal focused on environmentally sound policies and technologies” that would include solar power and potentially nuclear reactors, and reduce their dependency on fossil fuel exports.

To meet climate targets and avoid economic collapse, countries such as Iraq need international support in the transition to clean energy

• Ali Allawi is deputy prime minister and finance minister of Iraq. Fatih Birol is executive director of the International Energy Agency

In the Middle East and north Africa, global warming is not a distant threat, but an already painful reality. Rising temperatures are exacerbating water shortages. In Iraq, temperatures are estimated to be rising as much as seven times faster than the global average. Countries in this region are not only uniquely affected by global temperature rises: their centrality to global oil and gas markets makes their economies particularly vulnerable to the transition away from fossil fuels and towards cleaner energy sources. It’s essential the voices of Iraq and similar countries are heard at the Cop26 climate change conference in Glasgow this November.

To stand a chance of limiting the worst effects of climate change, the world needs to fundamentally change the way it produces and consumes energy, burning less coal, oil and natural gas. The International Energy Agency’s recent global roadmap to net zero by 2050 shows the world’s demand for oil will need to decline from more than 90m barrels a day to less than 25m by 2050. This would result in a 75% plunge in net revenues for oil-producing economies, many of which are dominated by a public sector that relies on oil exports and the revenues they produce.

An exchange in China’s Fujian province has set up the nation’s first trading platform for blue carbon credits, in expectation of a government-backed push for offset projects that store carbon in the ocean.

With a record-breaking number of entries from around the world, the judges of the 57th wildlife photographer of the year have had the toughest job yet.

From lynx making a comeback to a striking ecological disaster and narwhal shrimp communicating at great depths, there is an incredible range in the unique and fascinating images in the Natural History Museum’s exhibition. The photographs are a compelling reminder of the importance of the variety and variability of life on Earth in securing the future of our planet, revealed just ahead of the first phase of the global UN conference of Cop15 on biodiversity.
