In a recent letter, Ricke andCaldeira (2014Environ. Res. Lett. 9 124002) estimated that the timing between an emission and themaximum temperature response is a decade on average. In their analysis, they took into account uncertainties about the carbon cycle, the rate of ocean heat uptake and the climate sensitivity but did not consider one important uncertainty: the size of the emission. Using ...

In the past decade, fuel consumption and CO2 emission have increased in the airline industry. Large CO2 footprint has a damaging effect on the environment. Global concerns over this issue has made the airline industry to be greener. Most efforts of the green airline industry are improving the fuel consumption to reduce the CO2 emission and its environmental damage. Here, we use cruise speed con...

electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. electric motors account for between 43 and 46% of all global electricity consumption approximately. they give rise to about 6 040 mt of co2 emissions. end‐users approximately spend usd 565 billion per year on electricity [1]. in recent years, increase in e...

Reducing the CO2 levels in the atmosphere is one of the emerging challenges for human society. It is commonly accepted that CO2, as a greenhouse gas, is partly responsible for climate changes. It is thus important to reduce those CO2 levels in every possible way. This can be achieved in different manners, for example by decreasing CO2 emission by developing energy efficient processes with a red...

"Satisfying customers' traffic engineering connection requests is one of the biggest challenges of today's service providers. However, routing mechanisms which only consider service level specifications as the path selection criteria may not be aware of energy consumption and Co2 emission rate of the routed paths. This can generate huge Co2 emissions and consume energy inefficiently. This paper...

Global climate change due to CO2 emissions is an issue of international concern that primarily attributed to fossil fuels. In this study, Genetic Algorithm (GA) is used for analyzing world CO2 emission based on the global energy consumption. Linear and non-linear forms of equations were developed to forecast CO2 emission using Genetic Algorithm (GA) based on the global oil, natural gas, coal, a...

In the transport field, much attention is given to estimation and mitigation of CO2 emission. Much prior research has estimated CO2 emission using aggregate data on total energy consumed or average vehicles kilometres travelled (VKT), while not considering the influence on emission of factors that operate at a more resolved functional level, such as the neighbourhood-scale built environment (e....

Power generation industry is the key industry of carbon dioxide (CO2) emission in China. Assessing its future CO2 emissions is of great significance to the formulation and implementation of energy saving and emission reduction policies. Based on the Stochastic Impacts by Regression on Population, Affluence and Technology model (STIRPAT), the influencing factors analysis model of CO2 emission of...
