Frequently Asked Questions

Why do Node Pole launch a Fossil Free Data label?

Through the Fossil Free Data label Node Pole aims to set a new transparent standard for sustainable and fossil free data.

Node Pole are in a unique position to take a leadership role in sustainable data based on location, network, knowledge and capacity. As the tech industry develops, they see the need for a more proactive sustainability perspective and want to help ambitious companies demonstrate their sustainability efforts. This is why Node Pole introduces a transparent label for Fossil Free Data.

What criteria do applicants need to meet? 

In order to obtain the label, companies must meet certain criteria including the following:
·      100% renewable energy
·      World-class energy usage efficiency (≤1.4 Power Usage Effectiveness)
·      Less than 0.19 kg carbon emissions per kWh IT energy

The criteria are based on the iMasons DCPI report to identify modern and efficient data centers.

Why should data center actors apply for the Fossil Free Data Label?

The Fossil Free Data Label is a competitive and comparative tool for sustainability leaders.

As consumers shift their lifestyles toward environmentally-friendly products and put pressure on companies, many are beginning to realize that their data has a CO2 footprint. And as they do, demand will increase rapidly for sustainable data solutions.

What kind of documentation is needed when applying for the label?

The review process is based on the following documentation:

Renewable energy sourcing (market-based)

The value of this criterion requires a commitment to 100% renewable energy through the purchase of a 100% renewable energy certificate. The proof points of this commitment will be apparent via the following materials:

·       Energy attribute certificates that meet GHG ProtocolScope 2 Quality Criteria, such as Renewable Energy Certificates (RECs, I-RECs) or Guarantees of Origin (GOs).
·       Contracts for electricity (e.g. PPAs) where electricity attribute certificates do not exist or are not required for a usage claim.

Energy efficiency
Power Usage Effectiveness (PUE) is a benchmark comparing your data center’s infrastructure to your existing IT output. The PUE value is calculated by dividing the total power consumption of a data center by the amount of energy used by the IT equipment inside it, indicating efficient energy use. To meet the criteria, your energy efficiency of operation should be no higher than 1.4 PUE. The verification of energy efficiency will based on the following:

·      Actual measured PUE as defined in ISO 30134-2 international standard (12 month rolling value).

Low carbon emissions (location based)
Carbon Usage Effectiveness (CUE) is a metric developed by The Green Grid for measuring the carbon gas that a data center emits on a daily basis. Carbon emissions should be less than 0.19 kg CO2 equivalent per kWh used for IT equipment based on use of renewable energy, efficient use of energy and geographical emission factor.

CUE = PUE*CEF. Total CO2 Emissions caused by the Total Data Center Energy / IT Equipment Energy used (equal to iMasons DCPI Environmental grade A). The following apply to the low carbon emissions criteria: 

·      Own account using energy efficiency value (PUE) combined with official available data (CEF) from IEA (EPA in US).
·      Location-based Carbon Emission Factor (CEF) sourced from International Energy Agency (IEA- country data) or EPA for the US.

Why is the PUE limit set to 1.4?

A PUE of 1.4 represents modern and efficient data centers and the criteria are based on the iMasons DCPI report.

How do the different climate zones affect PUE?

Different climate zones affects PUE, but only in the second decimal.

How does capacity utilization affect PUE in datacenters?

Higher levels of capacity use give a slightly lower PUE, but the variation is not significant and only affects the second decimal (the criteria are based on the iMasons DCPI report).

Why is heat recycling not among the criteria?

Our focus initially is to only focus on energy efficiency. However, if you use electric energy for heat recovery, it can be deducted from PUE.

How long does the label last?

As long as your data center meets the criteria. Reviews and checks on how the criteria are met can be implemented.

How do one calculate a PUE for a recent established, or not yet constructed data center?

In this case it is applicable to use the option designed Power Usage Effectiveness (dPUE). (Calculated as per ISO 30134-2 international standard) However, a certification in such a case requires a re-submission of verified, actual PUE within the following 12-month period.

Is nuclear energy regarded as renewable energy?

The material most often used in nuclear power plants is a rare type of uranium, U-235. Uranium is a non-renewable resource. Consequently, nuclear energy is not regarded as renewable.
