The carbon footprint of the carbon feedstock CO2

investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

Estimation of the Carbon Footprint in Dairy Sheep Farm

By 2050, the earth’s population is expected to be more than 9 billion. The need for secure food and water supply will force agriculture to increase production. The major greenhouse gases (GHGs) from the livestock sector are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) throughout the production process. These gases are the key contributor to an in...

The importance of carbon footprint estimation boundaries.

Because of increasing concern about global climate change and carbon emissions as a causal factor, many companies and organizations are pursuing "carbon footprint" projects to estimate their own contributions to global climate change. Protocol definitions from carbon registries help organizations analyze their footprints. The scope of these protocols varies but generally suggests estimating onl...

The Carbon Footprint of Beef Production

Modern-day agriculture allows the average farmer to produce enough food to feed 125 other people. This is in sharp contrast to the historical agricultural systems exemplified by farming in the 1800s, when each farm could produce only enough food to feed one other family. The global population has increased in line with productivity, yet the rate of increase in meat consumption is greater than t...
