Dairy cows are ruminant animals that produce methane emissions. Methane is a potent greenhouse gas. Nitrous oxide, another greenhouse gas, is released from their manure and urine. Open manure storage can also generate methane. Energy is used to grow food for dairy cattle and that energy typically comes from fossil … [continued]
The recent failure of MethaneSAT, the widely publicized methane-monitoring satellite developed by the Environmental Defense Fund, attracted global attention. The satellite lost communication with ground control in June 2025, just 15 months after its launch, and was officially declared irrecoverable in July. This event disappointed climate scientists, environmentalists, and policymakers … [continued]
If you like learning about various foods, the United States Dept. of Agriculture’s FoodData Central might be for you. It is a searchable online database with a massive amount of information about nutrients in a huge range of foods. Within the publicly available database, I searched used the term ‘almonds.’ … [continued]
After writing about two of the highest carbon foods, which are beef and lamb, it seems a mini-series is developing. The next high-carbon food, to make a trio, is farmed shrimp. Some of us may have had a kiddie shrimp cocktail or taken a family vacation to a southern state, … [continued]
After writing about how high in carbon beef is and some of its other problems, it seemed logical to consider what other animal-based foods are also high carbon. There are many, including one of the highest-carbon, which is lamb. Lambs and mature sheep are ruminant animals that emit methane, a … [continued]
It has been a few months since CleanTechnica reported on the innovative Australian company, ClearVue, so it is high time for an update. You can read our previous coverage here, and the connection with the US military here. As we see with most new technologies, it takes time and collaboration … [continued]
Generation Z (Gen Z), born between 1997 and 2012, are aged 13–28. They’re a perceptive group. Behind-the-scenes marketing strategies aren’t a secret to this generation — Gen Z has been digitally savvy since their earliest years on their LeapFrog LeapPads. They were raised with the internet and now are highly … [continued]
There is an idea floating around online that because fossil fuel corporations generate the most greenhouse gas emissions and therefore are the most responsible for climate change and its impacts that individual humans don’t really need to do much to reduce our own personal carbon footprints. This reasoning doesn’t make … [continued]
As the world seeks urgent solutions to decarbonize food systems, two nature-based technologies are gaining traction for their ability to tackle multiple challenges at once: Biochar Carbon Removal (BCR) and Enhanced Rock Weathering (ERW). Together, these approaches not only sequester carbon at scale, but when used in the correct contexts … [continued]
Today is the 4th of July in the US. Around the country people will be firing up their grills and eating juicy hamburgers. Few party-goers, though, will think about the methane emissions that result from vast herds of US factory farmed-cattle. Scientists have been trying for years to find just … [continued]
