This paper focusses on conceptualizing the quantification of the Carbon Footprint of IT-Services (CFIS). Initially, the increasing relevance of Carbon Footprint to the IS-community is pointed out. Based on literature review, we present related work that describes underlying concepts e.g. the Carbon Footprint of Products, Life Cycle Assessment as well as IT energy and performance measurement. We...

Hydropower in boreal conditions is generally considered the energy source emitting the least greenhouse gas per kilowatt-hour during its life cycle. The purpose of this study was to assess the relative contribution of the land-use change on the modification of the carbon sinks and sources following the flooding of upland forested territories to create the Eastmain-1 hydroelectric reservoir in Q...

The enormous growth in enterprise networks such as cloud computing and social networking increase the network traffic, thereby contributing considerably to the total carbon emission within the network. In this paper, we present a comparison study between transportlayer communication protocols relative to carbon footprint within enterprise network. The comparative study focuses on three factors:...

Due to the increasing use of Cloud computing services and the amount of energy used by data centers, there is a growing interest in reducing energy consumption and carbon footprint of data centers. Cloud data centers use virtualization technology to host multiple virtual machines (VMs) on a single physical server. By applying efficient VM placement algorithms, Cloud providers are able to enhanc...

Conventional cellular wireless networks were designed with the purpose of providing high throughput for the user and high capacity for the service provider, without any provisions of energy efficiency. As a result, these networks have an enormous Carbon footprint. In this note, we describe the sources of the inefficiencies in such networks. First we quantify how much Carbon footprint such netwo...

Streaming movies over the Internet has become very popular in the recent years. It is giving a stiff competition to the alternative method of DVD being shipped to the customer, after an order is placed online. It is likely that in future, the online streaming method will displace the DVD shipping method. In this paper, we evaluate the environmental impact of such a paradigm shift in delivering ...

A systematic analysis of green-house gases emission (carbon footprint) and primary energy consumption (energy footprint) of prefabricated industrial buildings during their entire life cycle is presented. The life cycle assessment (LCA) study was performed in a cradle-to grave approach: site-specific data from an Italian company, directly involved in all the phases from raw material manufacturin...

A spring calving herd consisting of about 350 beef cows, 14-16 breeding bulls, 60 replacement heifers and 112 steers were used to compare the whole-farm GHG emissions among calf-fed vs. yearling-fed production systems with and without growth implants. Carbon footprint ranged from 11.63 to 13.22 kg CO₂e per kg live weight (19.87-22.52 kg CO₂e per kg carcass weight). Enteric CH₄ was the largest s...
