CO2

The article discusses carbon capture and storage (CCS) as a technology central to many nations' net-zero strategies, with the UK investing £21.7bn in its development. Critics argue CCS is costly, tied to fossil fuels, and unproven at scale, while organizations like the IPCC emphasize its importance for decarbonizing high-emission industries.

A study suggests organic eggs have twice the climate impact of caged chicken eggs, with switching UK egg production to an organic free-range model emitting 2,316,000 tonnes of CO2 equivalent, compared to 1,184,000 tonnes for caged systems.

The article discusses how elevated CO2 levels in indoor environments may impair decision-making and cognitive performance. It references a study suggesting poor air quality can act as a bottleneck for productivity and clarity of thought.

Greenhouse gas emissions reached an all-time high of 56.8 billion tonnes of CO2 in 2024, according to a study. Climate scientists have called for urgent action to address the rising emissions.

UK vehicles will emit an extra 17m tonnes of CO2 by 2030 due to a loophole allowing more plug-in hybrid electric vehicles (PHEVs). Campaigners urge the government to resist weakening electric car sale rules, while parts of the car industry call for a second review of regulations requiring increasing electric vehicle sales.

A German town in Bavaria uses a local currency called 'Chiemgauer' to support businesses and reduce carbon emissions. The initiative began as a school project and has since evolved into a tool for environmental sustainability.

Cement production accounts for about 8 percent of global CO2 emissions, and a new paper suggests using a different type of rock could eliminate direct process emissions. The current method of producing Portland cement releases CO2 gas as a byproduct. Researchers are exploring alternative methods to reduce emissions.

A new metric shows that compound climate extremes rise faster with cumulative CO2 emissions than models project, implying higher risks and smaller remaining carbon budgets for the 1.5 °C and 2 °C targets. The study was published in Nature. Cumulative CO2 emissions have a significant impact on climate extremes.

A study published in Nature corrects previous data, confirming that atmospheric CO2 and CH4 levels have remained broadly stable over the past 3 million years. The correction addresses prior analyses to ensure accurate representation of long-term greenhouse gas trends.

The Middle East crisis is causing potential shortages of chicken and pork, with ministers considering CO2 rationing to address supply issues. Product availability concerns are rising amid geopolitical tensions.
