Finally, C14 dating is not able to date very old fossils. It is often assumed that carbon dating can date anything. But with a 5600 year half life, anything over 45,000 years will only have 1/16th the concentration of C14 it had when the animal died. As concentrations decrease, the me...

LOW-CARBON CITY LIFE The concept of green development has enabled Changzhou not just to prosper economically and reduce carbon emissions, but also to create a low-carbon lifestyle for its residents. The city recently built an advanced heat-storage station, which can extract leftover heat from in...

Similar to carbon intensity, higher efficiency in carbon emission control and larger scale of breeding can reduce the carbon footprint growth of live pigs by half [27]. Besides the production-related factors, other factors that influence carbon emissions include labor prices, land prices, livestock...
Finally, improving the quality of life in cities increased the total carbon emissions due to increased demand for larger living spaces and more vehicles and increased the use of home electronic appliances. For example, China has become the world leader in vehicle manufacturing and sales since 2009...
(Fig.4a). In pathways of moderate and slower decarbonisation, the energy share increases in the second half of the century. The average share of energy for the energy system in the fourteen pathways for the median-EROI scenario during the 2020–2030 period is ~14%, with the highest ...
