Investigations suggest a large share of ‘used’ cooking oil being imported could be wrongly labelled as demand outpaces supply

Tighter rules are needed to ensure that the imported “used” cooking oil that airlines hope will power cleaner flights is not in fact virgin palm oil, campaigners have warned.

About 80% of waste oil is imported to create biofuels that are mostly still used in cars, vans and lorries despite growing demand from aviation. About 60% of those imports come from China.

The US Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management (FECM) is looking to advance infrastructure for transport and storage of CO2 from industrial and power generation sources in pursuit of federal climate goals.

California boosted the issuance of compliance-grade offsets since the prior distribution in November, but none of the credits were tagged with direct environmental benefits to the state (DEBs) this time round, according to data published by the state regulator ARB on Wednesday.

Voluntary carbon market (VCM) proponents are pressed to bring integrity to the ecosystem with new tools outlined across multiple events on the sidelines of the COP28 UN climate summit, but the collapse of negotiations on international emissions trade in Dubai may hinder efforts to converge markets.

Bolivia has signed a memorandum of understanding (MoU) with a global carbon standard to educate stakeholders and share knowledge about the nation's carbon market activity.

AEMO says more gas power might be needed to cover early coal closures, but predicts longer term decline as wind, solar and storage over growing demand for electrification.

The post AEMO says more gas needed in W.A. to cover coal exits and electrification, but maybe not appeared first on RenewEconomy.

Researchers evaluating the robustness of carbon credit baselines for jurisdictional-scale avoided deforestation projects have exposed serious challenges in their accuracy and consistency, according to a new study.

Looming over this year’s climate talks was the spectre of Donald Trump regaining the US presidency

The climate emergency needs better than this. It has taken almost 30 years of climate talks for the world to call on nations to transition “away from fossil fuels” in a “just, orderly and equitable manner”. Cop28’s final text was stating the obvious but it needed saying, and not a moment too soon. Ahead of the Dubai summit, the UN said that under current policies, global temperatures were on track to rise 2.9C above pre-industrial levels – nearly double the goal cited in the climate summit final declaration.

The measures agreed – to triple renewable capacity and double the rate of energy efficiency – could limit warming to the 1.5C threshold. But this relies on an equitable climate financing deal for developing countries. On this key issue, the Cop28 outcome had little to say. A report for the UN has stated that developing countries – excluding China – would need $2.4tn a year. This is a lot of money, but then what is the price of saving the planet? The US is the richest nation on Earth. It should take the lead as the globe’s largest oil and gas producer. Instead it will expand fossil fuel extraction – reckless and inexcusable behaviour given Washington’s historical responsibility.

The agreement on fossil fuel phase-out is full of loopholes, but those of us fighting for climate justice won’t give up

As Cop28 ended after 14 gruelling days, many people were clutching at straws and looking for meaning in the mere mention in the text of a transition from fossil fuels. There will be headlines talking about what huge progress it is simply to say this – even without any requirement for real action.

This would have been very welcome 20 or even 10 years ago, but it wasn’t the gamechanger needed to prevent climate catastrophe, to end the era of deadly fossil fuels, or to save the north star of 1.5C. To claim that it is a triumph, or anything even close to that, is simply a lie.

Developing countries call agreement to transition away from fossil fuels ‘unfair’ and ‘inequitable’

As the leaders of the developed world hailed the Cop28 agreement to “transition away” from fossil fuels as historic, Indigenous people, frontline communities and climate justice groups rebuked the deal as unfair, inequitable and business as usual.

The global stocktake (GST) – and the entire UN talks – were dominated by whether or not agreement could be reached to phase out or phase down fossil fuels – in order to curtail global heating.
