A debate over finance was the dominating narrative at the UN climate talks taking place in Bonn yesterday. The BBC looks at an intervention by 134 of developing countries, who demanded that developed nations commit to scaling up public climate aid in December’s UN deal. The group said that rich nations have not followed through on their previous commitments, and also dismissed the findings of a recent OECD report which aims to track financial flows. Climate Home and Reutersalso wrote about the debate.

OPEC nations including Iran, Saudi Arabia and Nigeria have told Reuters that they will submit their climate plans to the UN ahead of its conference in Paris this December. These oil-producing nations are among the last ones not to have submitted a pledge to tackle their emissions. Pakistan and Egypt have also said they will come forward over the next month. Meanwhile, the United Arab Emirates submitted its pledge yesterday. Climate Home looks at its targets.

President Barack Obama will publish his climate change regulations on Friday, and up to 25 states are already planning on legal action to block them. The Clean Power Plan is at the heart of Obama’s efforts to tackle climate change, and will place stringent new requirements on power plant emissions. Inside Climate News points out that, even while opposing the rules, states are already looking at how they can comply, in the event that they lose their case. Reuters also covers the story.

The head of the Green Climate Fund has said she is confident that the US will deliver on its pledge to donate $3bn to developing countries, despite Republicans labelling the UN-backed bank a “slush fund”. Hela Cheikhrouhou said she was confident that the transparency and accountability standards set by the bank would reassure observers. Reuters reports that the GCF aims to allocate its first round of funding in November, ahead of the UN climate talks in Paris.

The International Energy Agency (IEA) is set to release a report on the benefits of “advanced technology” coal power stations. Seen by the Guardian, it has been produced by a group of coal industry executives that advise the IEA. The report does not mention climate change, the Guardian says, and has been criticised by financial experts as “deeply misleading”.

The steel industry might be in crisis, but it is the solar power industry that is really being “savaged” by government policies, writes Ian Birrell. Despite both international and domestic commitments to low-carbon energy, the government has withdrawn subsidies and handed out power to locals to stop new projects. This has already created job losses, he writes, with four major players already going out of business.

A footnote in the government’s Hinkley deal with China says that it is ending its “no public subsidy” policy for nuclear. This conflicts with the government cuts in subsidies for renewable energy, writes Guardian environment editor Damian Carrington. Meanwhile, a policy “reset” will create unnecessary uncertainty to investors, he adds.

A new study examines what an emissions trading scheme in China would look like from ethical and economic standpoints. The scientists look in particular at the role of emissions permit allocation and conduct a survey with Chinese climate-policy experts, who show strong support for allocating emissions permits based on consumption-based emissions with less burden on the western provinces, a medium burden on the central provinces, and a high burden on the eastern provinces.
