Solar Radiation Modification might provide an auxiliary tool to help reduce climate risk, limit suffering, lessen ecosystem degradation and improve the chances of sustainable development, but SRM is far from perfect, write scientists Claudia Wieners, Ben Hofbauer, Iris de Vries, Matthias Honegger, Daniele Visioni, Herman Russchenberg, and Tyler Felgenhauer in an open letter already supported by around 50 global scientists.

Scientists are calling for increased research and governance into solar geoengineering as the controversial practice may be deployed to help curb warming amid accelerating climate change, cautioning against the current free-for-all that has resulted in the first privately-funded "carbon cooling" credits.

Draft plan addresses inflated claims about products’ environmental credentials

Companies will have 10 days to justify green claims about their products or face “effective, proportionate and dissuasive” penalties, under a draft EU crackdown on greenwashing seen by the Guardian.

Inflated claims by firms about their products’ environmental bona fides have grown along with public awareness of global heating in recent years.

Complaint filed against retail giant after an experiment found that the teabags did not biodegrade after a year buried in soil

A team of researchers has filed a complaint against Tesco, saying its “biodegradable” teabags do not fulfil that claim following an experiment that involved burying them in soil for a year to see what happened.

Dr Alicia Mateos-Cárdenas from University College Cork (UCC) set out to investigate how well teabags advertised as biodegradable broke down. She buried 16 Tesco Finest Green Tea with Jasmine pyramid teabags in garden soil. However, when the teabags were dug up, they remained intact.

Australian Academy of Science report says country is behind others in carbon dioxide removal and a nationally coordinated approach is urgently needed

Australia should set targets for the amount of carbon dioxide that could be pulled permanently from the atmosphere using “carbon drawdown” techniques like tree planting and direct air capture, according to a report from the Australian Academy of Science.

A national coordinated approach is urgently needed to promote projects that remove carbon dioxide from the air, the report says, with a lack of policies seeing Australia fall behind other countries.

Almost one-third of homes have panels, the highest in the world, says SunWiz, and will soon outpace capacity from coal

Australia’s rooftops now boast 20 gigawatts of solar panels and will soon have the capacity to produce more electricity than the country’s entire coal industry, according to the industry consultancy SunWiz.

Almost one in three Australian households have solar photovoltaics – or solar panels - the highest penetration in the world. Queensland had the highest share of solar panels installed on dwellings deemed suitable for the technology with an 82% penetration, ahead of South Australia’s 78%, New South Wales’ 51% and Victoria’s 43%.

Were we able to perceive afresh the sheer scale of fossil fuel impact we might be horrified, but because this is an old problem too many don’t see it as a problem

If fossil fuel use and impact had suddenly appeared overnight, their catastrophic poisonousness and destructiveness would be obvious. But they have so incrementally become part of everyday life nearly everywhere on Earth that those impacts are largely accepted or ignored (that they’ve also corroded our politics helps this lack of alarm). This has real consequences for the climate crisis. Were we able to perceive afresh the sheer scale of fossil fuel impact we might be horrified. But because this is an old problem too many don’t see it as a problem.

Human beings are good at regarding new and unfamiliar phenomena as dangerous or unacceptable. But long-term phenomena become acceptable merely because of our capacity to adjust. Violence against women (the leading form of violence worldwide) and slower forms of environmental destruction have been going on so long that they’re easy to overlook and hard to get people to regard as a crisis. We saw this with Covid-19, where in the first months most people were fearful and eager to do what it took to avoid contracting or spreading the disease, and then grew increasingly casual about the risks and apparently oblivious to the impacts (the WHO charts almost 7 million deaths in little over three years).

Popularity of sport utility vehicles driving higher oil demand and climate crisis, say experts

The continued global rise in sales of SUVs pushed their climate-heating emissions to almost 1bn tonnes of carbon dioxide in 2022, according to the International Energy Agency.

The 330m sport utility vehicles on the roads produced emissions equivalent to the combined national emissions of the UK and Germany last year. If SUVs were a country, they would rank as the sixth most polluting in the world.

European carbon prices stabilised at around €100 on Tuesday morning after a strong auction offset early weakness, though the market continued to seek a definitive direction as more analysts issued cautious reports predicting price weakness.

A major Asian investor organisation on Tuesday launched an initiative to support regional investors in developing risk management processes and investment policies to help ending deforestation.

The EU's upcoming second ETS covering buildings and road transport may not be enough to deliver emissions cuts by individuals and small businesses, according to an analysis published this week.

Switzerland has authorised another emissions trade transaction under Article 6.2 of the Paris Agreement, striking a deal with Thailand for the first time as it continues to leverage bilateral agreements between nation states to meet its climate targets.

Stakeholders in African forest carbon expressed scepticism about the prospects for significant progress on channelling sufficient funding to the sector during an upcoming summit to be held in Gabon, with the role of carbon credits also expected to be a significant point of discussion.

Fishing will be banned to allow nature to recover in three areas but critics say the plans lack ambition.

Australia experiences slight rise in emissions, as increased use of diesel and jumps in agriculture emissions offset gains from use of wind and solar in the grid.

Climate activist Greta Thunberg joins protesters calling for removal of two wind farms found to have interfered with indigenous rights.

The wave of bullish sentiment that has driven EUA prices to record highs in the past week does not reflect market fundamentals and is unlikely to prevent a pullback because macroeconomic factors are likely to exert an influence for much of the current year, according to bank analysts.

A European oil firm has signed a letter of intent with the forestry commission of Ghana to secure as many as 1.2 million credits from nature-based carbon projects in the country as part of a jurisdictional REDD+ deal, local media sources reported.

Norway's government has invested NOK 36.3 million ($3.5 mln) in a direct air capture pilot project, the first funding provided by the country for the technology, according to a release Tuesday.

The Just Energy Transition Partnership (JETP) deals made with Indonesia and Vietnam represent significant initial breakthroughs in transitioning these key Asian economies from coal reliance, but their longer-term impact will largely depend on how the agreements will be operationalised by both governments to bring about an earlier coal-phase out date, according to analysts.
