Tanzania has urged East African heads of state to take a common stance ahead of COP28 in opposing the dominance of foreign firms in the region’s carbon trading activities, according to domestic media sources.

The European Commission will put forward an action plan for upgrading the bloc's electricity grids in which it estimates €584 billion in investments are necessary by 2030 to deal with the influx of renewable energy, according to a leaked document seen by Carbon Pulse.

Ove Hoegh-Guldberg’s pioneering research in the 1990s found increasing sea temperatures would damage the world’s coral reefs, killing them faster than they could recover. Hoegh-Guldberg speaks with Guardian Australia about being labelled an alarmist while championing one of the world’s richest ecosystems.

This video is part of Weight of the World: a climate scientist's burden. The series features three pioneering Australian climate change scientists - Graeme Pearman, Lesley Hughes and Ove Hoegh-Guldberg. The series tells the story of how the three scientists made their discoveries, how they came under attack for their science and the personal toll it has taken on them. And importantly, how they stay hopeful.

The existential battle against global heating requires connecting science, politics and community life, often much harder than it looks

A lot of the time, politics feels incremental. But every now and again, a big thing happens suddenly. Chris Bowen made it clear this week the government intends to transform the fundamentals of Australia’s energy grid. Labor has been saying this for ages of course, but this week, words were matched by a concrete plan of action.

Bowen unveiled a radical expansion of a capacity scheme intended to reshape the national electricity market. Coal is coming out, renewables moving in and taxpayers will underwrite the transformation. This is the biggest strategic shift Australians have seen in this policy area for a decade or more.

The Philippines has signed a memorandum of understanding (MoU) with a local climate tech firm which will help the nation to build an ITMO registry, setting the stage for the country to enter the carbon market, local media reported Friday.

The Global Investor Commission on Mining has been backed by 82 investors with over $11 trillion in assets collectively under management, with the aim of making the sector more socially and environmentally responsible by 2030.

Study’s author says ‘we need to reduce exposure in order to ensure men who want to conceive are able to without interference’

Exposure to several widely used insecticides probably decreases sperm concentration and may have profound effects on male fertility, new US research finds.

The George Mason University paper analyzed five decades of peer-reviewed studies to determine if organophosphates and carbamate-based pesticides exposure correlated with decreased sperm concentration.

European carbon prices advanced for a second day, giving rise to speculation that the month-long decline fuelled by speculative selling may have come to an end as the expiry of the December contract approaches, while energy markets were slightly weaker as the weather outlook remained uncertain.

Global fall averaged 4.2% between 2010 and 2022 but would have been far more if vehicle sizes stayed same

Emissions from the motor sector could have fallen by more than 30% between 2010 and 2022 if vehicles had stayed the same size, a report has found.

Instead, the size of the average car ballooned as the trend for SUVs took off, meaning the global annual rate of energy intensity reductions – the fall in fuel used – of light-duty vehicles (LDV) averaged 4.2% between 2020 and 2022.

Project aims to release hundreds into lochs and streams after centuries of habitat loss and exploitation

The medicinal leech is one of nature’s least loved hunters. Armed with three strong interlocking jaws and with a taste for blood, they will swim hungrily towards humans, deer or cattle that wander into their ponds to bathe, fish or drink.

Yet this small predator is the focus of an unlikely reintroduction programme by conservationists working in a small laboratory deep in the Scottish Highlands, at a wildlife park best known for its polar bears, wildcats and wolves.

Trading volume in China's carbon market plunged over the past week despite stable allowance prices, as most major Chinese emitters have fulfilled their obligations now that the primary compliance deadline set by the government has passed.

Revenues from carbon pricing mechanisms reached $93 billion last year, slightly lower than the prior year, with more than half of this total specifically redirected towards climate activities, according to a report from a group of climate economics researchers.

More than 50 people dead in Tigray and Amhara regions while UN warns of ‘crisis-level hunger or worse’ in Somalia

The regions of Tigray and Amhara in northern Ethiopia have continued to experience severe drought conditions with more than 50 people dead, as well as 4,000 cattle.

While northern Ethiopia suffers from droughts, the southern and eastern parts of the country, along with Kenya and Somalia, have been hit by flooding. Somalia suffered the worst of the flooding, with 50 people reported dead. According to the Somali disaster management agency almost 700,000 people have been forced to leave their homes.

South Korea may push back the timeline for the release of a basic plan underpinning the next phase of the domestic carbon market, which has been hampered by an oversupply of emissions permits, local media reported. 

The federal government of Pakistan is considering a cap-and-trade model for its imminent carbon market, an official said according to local media.

European Environment Agency says half of deaths could have been avoided by cutting pollution to recommended limits

Dirty air killed more than half a million people in the EU in 2021, estimates show, and about half of the deaths could have been avoided by cutting pollution to the limits recommended by doctors.

The researchers from the European Environment Agency attributed 253,000 early deaths to concentrations of fine particulates known as PM2.5 that breached the World Health Organization’s maximum guideline limits of 5µg/m3. A further 52,000 deaths came from excessive levels of nitrogen dioxide and 22,000 deaths from short-term exposure to excessive levels of ozone.

A Japanese university will invest in a direct air capture (DAC) venture that aims to begin capturing CO2 via nano-separation membranes later this decade.

A Swedish drone firm has been granted a €2.7-million grant by the government for a three-year project to refine forest-thinning technology it says will reduce the need for energy intensive, habitat-wrecking heavy machinery on the ground.

Letter says government pushing ahead with new fossil fuel projects while criminalising activists who raise alarm

Emma Thompson, Stephen Fry and Ben Okri have joined the former archbishop of Canterbury Rowan Williams and leading climate scientists to highlight what they describe as a “collective act of madness” that is driving “the destruction of life on Earth”.

A letter signed by more than 100 actors, authors, scientists and academics says the UK government is ignoring the scientific reality of the climate and ecological crisis, pushing ahead with new fossil fuel developments and criminalising peaceful protesters who raise the alarm.
