Customer Climate Report
EcoDataCenter provides a monthly customer CO2e reporting service
Together with independent leading expertise within sustainability and data centers (John Booth and Nick Morris, Carbon3IT), EcoDataCenter has created a monthly Climate Report for their customers.
The report is based on Green House Gas Protocol standards and aims to fully disclose all relevant carbon footprints associated with the customers’ data center operations.
Unique open-source Climate Report
Customers of EcoDataCenter now recieve a transparent climate report from their data center operations every month
Read more about our sustainabilityBy doing this, we pave the way for the industry to follow. That's why we are fully transparent and disclose all emissions associated to the data center.

Scope 3
Carbon Emissions
The term Scope 3 Carbon Emissions represent all the carbon emissions associated with producing a finished physical project. These emissions arise from the point of acquiring the raw materials right through to production of components, their transport and assembly of the final product. In the case of a building this includes preparation of the site and construction.
Carbon Emissions
Building
Once the building has been commissioned, its Scope 3 emissions remain largely unchanged for duration of its operational use, with quantitatively minor changes occurring when components are replaced or minor renovations occur.
The figure illustrates the case of a building that has 200,000 Kg CO2e embodied-, or Scope 3 carbon emissions. If the building has an operational lifetime of 30 years, then the Scope 3 carbon may be allocated approximately evenly across each month of this period, as illustrated. In this example, the monthly Scope 3 carbon allocation, or ‘rate’, is 200,000 𝐾𝑔 𝐶𝑂2𝑒 360 𝑚𝑜𝑛𝑡ℎ𝑠=556 𝐾𝑔 𝐶𝑂2𝑒/𝑚𝑜𝑛𝑡ℎ.
Example
IT Infrastructure Use
Consider Client C, whose IT services use 2% of the total IT energy use in each month, m. For a total IT energy use of 5,952,000 kWh, corresponding to an IT load of 8MW, Client C has used 119,040 kWh of energy.
Building Completeness
Embodied Carbon
Since the monthly quantity of building-related Scope 3 carbon required to support operation of the data center is 556 Kg CO2e, the proportion of this value required to delivery of Client C’s services may be considered as the direct proportion of IT energy used by Client C in that month, in this case 2%. Hence, the quantity of building-related Scope 3 carbon required to support Client C’s activity in this month is 556 𝐾𝑔 𝐶𝑂2𝑒 ∙2% ~11 𝐾𝑔 𝐶𝑂2𝑒, as illustrated.
Uptake
IT-load
The selection of planned optimum IT load (design operating load) for the reference value for determining the proportion of IT energy used by Client C reflects the fact that for most of the operational lifetime of the data center, the actual capacity will be far from the values in initial client acquisition mode and much closer to planned optimum load.
This approach is coherent with the fact that the building Scope 3 carbon emissions are also distributed throughout the operational lifetime of this asset. The uptake in IT load for the example above is illustrated in the figure.
Scope 3 – Carbon Emissions
Data Center Infrastructure
The same approach described above for building-related Scope 3 carbon may be applied to data center infrastructure Scope 3 carbon. A key difference between the two asset classes, infrastructure and building, is that the operational life of infrastructure components is likely to be less than that of the building. Here the monthly Scope 3 carbon allocation is distributed across the whole set of infrastructure assets and the proportion supporting a client’s services evaluated as for building-related Scope 3 emissions. Consider a single infrastructure asset with Scope 3 carbon of 1000 Kg CO2e which is replaced every ten years. The monthly Scope 3 carbon allocation from this asset is simply: 1000 𝐾𝑔 𝐶𝑂2𝑒120 𝑚𝑜𝑛𝑡ℎ𝑠~8.3 𝐾𝑔 𝐶𝑂2𝑒/𝑚𝑜𝑛𝑡ℎ.
The value apportioned for any client’s services in that month is evaluated using the ratio of IT energy used versus total IT energy, as described previously, illustrated in the figure
The total monthly data center infrastructure Scope 3 quantity is therefore simply the sum of all the monthly rates for all infrastructure assets. Note that reuse by a third party at end of operational use in the data center will simply reduce the effective monthly Scope 3 rate allocated within the time and physical system boundaries of the data center.
Scope 1 and Scope 2
Diesel Generators and Data Center Infrastructure
Direct emissions of carbon occur directly due to the use of diesel backup power generators. A known quantity of diesel with associated carbon emissions is used monthly. Likewise, the quantity of energy and associated carbon emissions arising from operating data center infrastructure responsible for cooling, power and so forth are quantified monthly. These emissions are apportioned as supporting client IT services in the same way as described for Scope 3 emissions.
Direct Power Consumption
Customer Equipment
The actual customer specific power consumption measured at the PDU level, the same amount of power every customer is billed per month. The value is used to determine the customers part of the total max IT-power for each specific data center building.
Shared Power Consumption
Data Center Infrastructure
This segment of the report consists of the customer part of shared power consumption for the specific data center building that the customer is located in. Everything above the PDU level in terms of infrastructure as DH units, AHUs, chiller/adiabatic compressors, CRACs etc. Equipment that is shared among all customers in the same data center building.
Comparison
Swedish Traditional DC
The benchmark for the standard Swedish data center was made using the model of a data center of the same IT capacity (8MW), built with standard construction methods*, on the assumption of identical Mechanical and Electrical Infrastructure and a PUE of 1.5, probably close to the mean PUE for Swedish data centers. The carbon intensity (or Emissions Factor) of the electricity used to power the standard model data center was the same as for EcoDataCenter**, and with representative transmission and distribution losses of 8%, versus quantified value for EcoDataCenter of 1%.
* EcoDataCenter uses structural wood in place of steel wherever possible, resulting in cumulative reductions in required load throughout the building structure, foundations and energy required for site preparation, with associated and carbon emissions.
