- The bottleneck might be the air in the room
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 have hit an all-time high: Study reveals how 56.8 BILLION tonnes of CO2 were released in 2024 - as climate scientists call for urgent action
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 urged not to further weaken EV rules as CO2 impact revealed
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.
- The German town where locals spend play money to cut CO2
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.
- Making cement from a different type of rock could clean up emissions
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.
- Enhanced response of extreme compound events to cumulative CO 2 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.
- Author Correction: Broadly stable atmospheric CO 2 and CH 4 levels over the past 3 million years
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.
- Brace for summer of shortages: Chicken and pork among products facing crunch from Middle East crisis as ministers 'plan for rationing CO2'
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.
