We regularly advise our clients on their Finland WhatsApp Number List strategy for their applications and data. These strategies take into account the costs and financial issues of our recommendations. The choice is usually on hosting in the Cloud or On-Premise. We have never studied the CSR impact of these choices in the past, but we are now able to do so and we can help you . Here are some elements on a limited scope, with a focus on greenhouse gas (GHG) emissions in the case of ISLEAN. For lack of studies and documents on this subject, I propose to restrict ourselves to the case of a consulting firm like ours for which I have access to

information such as the amount of data hosted and the use of the network. I will also study what is happening in RUN, and exclude transformation projects and assets from the scope of the article. We host the majority of our 2TB or so of data on a Google Cloud. Our ERP mainly on Google Workspace and our applications are also mainly online. Our network usage to access and work is approximately 2.5GB per day per consultant . The majority is devoted to the use of video, followed by access to our work tools and our documents.

Data and applications

What are our current emissions related to data and application hosting? What would be the CSR impact (emissions in particular) if we decided to migrate our data and on-premise applications from the cloud? We have already assessed the contribution of our storage, grid usage and applications when we did our carbon footprint . The hosting of our data globally emits 4 tonnes of CO2 per year just by their energy consumption. Our use of applications offered by Google (excluding video, already taken into account elsewhere), generates a maximum consumption of 110 kWh per year in a Google datacenter, hosted in Ireland. (1)


You have to realize that these figures come from marginal consumption. They do not take into account machine and room construction actions or maintenance activities. A web host such as Google optimizes its energy consumption more easily than a company which is not its core business. (2) For each kWh consumed directly by a Google server, an additional 0.1 kWh is necessary to make it work (air conditioning, etc.). For a typical company not specialized in this trade, it is necessary to count 1 kWh indirectly consumed for 1 kWh of energy used by the server.

Cloud hosting

Assessment of our emissions linked to the use of applications and Cloud hosting: 5.44 tonnes of CO2 equivalent for 22 consultants, or 247 kg of CO2 equivalent per consultant or 6.69% of our emissions. What would happen if we hosted our data on a NAS ( Network Attached System ) ourselves and worked with equivalent tools hosted locally on a server? To obtain an equivalent level of service to the firm, we should acquire a server with sufficient storage capacity, computing power and connectivity to serve all users of the firm on site or remotely. It is also necessary to ensure a redundancy equivalent to that offered by the host, so install 1 server in 3 different places.

We choose for the example a Netgear ReadyNAS 3312 (3). Commissioning and migration would involve other actions and therefore other emission factors. This should include the storage of additional data, construction of the machine, rooms, installation, maintenance in operational conditions, supervision, and renewal of equipment. To make a fair comparison, we will not take these actions into account because we do not have access to the equivalents at Google. We only consider the energy consumption of the servers and the indirect consumption to make them work.
