China is the world's largest emitter of carbon dioxide – a potent greenhouse gas – accounting for 28 percent of the world's total output every year. In 2019, China's emissions surpassed those of the U.S., Europe and Japan combined. Despite China's per capita emissions being less than...
To fight fire, use water, carbon dioxide, dry chemical, fog, mist.Water and foam may be ineffective on fire.If material on fire or involved in fire: Do not extinguish the fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may spread fire....
which is formed as a byproduct of degraded anesthetic agents by carbon dioxide absorbents, and endogenous CO that is formed by the body and rebreathed in closed-circuit, low flow anesthesia. Low flow anesthesia is a technique to conserve anesthetic agents and associated costs by using a fresh ...
The conversion of carbon dioxide to value-added products using renewable electricity would potentially help to address current climate concerns. The electrochemical reduction of carbon dioxide to propylene, a critical feedstock, requires multiple C–C coupling steps with the transfer of 18 electrons per...
Carbon dioxide (CO2) blood tests evaluate the presence of the gas in your blood. If your CO2 levels rise too high or fall too low, the test results may be an indication that you have a health condition that needs diagnosis and treatment. ...

Global warming and fuel depletion are currently driving the scientific community toward technologies based on capture, storage and conversion of carbon dioxide. CO2ER demonstrated to be an effective way to produce low-carbon fuels starting from waste CO2, thus contributing to a sustainable development ...
Human actions—primarily burning fossil fuels but also deforestation and other activities—have resulted in a rapid increase in the concentration of GHGs in the atmosphere. GHGs, including carbon dioxide, methane, and nitrous oxide, trap heat close to the surface and cause global temperatures to ris...
Carbon trading, which allows buying and selling permits to emit carbon dioxide or other greenhouse gases, is regarded as one of the most critical tools to help reduce carbon footprints and meet emissions targets. "Overall, the basic framework of the national carbon market has been initially establ...
