A white paper describes the ECR specification in further detail.

The ECR is applicable to a large number of communities:
ECR for Businesses
The ECR defines an energy-efficiency rating applicable to Internet service providers as well as all ICT-dependent enterprises.
The ECR ratings can be utilized for enterprises purchase decisions, providing an immediate and direct means of reducing energy relative to expenses in data centers and private network infrastructures. Data centers provide the horsepower for the global economy, and the cost of energy consumption by enterprise telecom centers can no longer be ignored. The ECR allows educated decisions to be made related to equipment selection and network design
In addition, ISPs can benefit from the ECR specification by reducing the internal test effort required to qualify equipment for internal corporate standards and external government-driven goals and regulations. Telecom products carrying ECR readings can be easily compared against each other during the network design and RFP processing stages at no extra cost or effort. In addition, the ECR methodology provides a turn-key infrastructure for energy and facility planning, allowing operational expenses to be kept under tight control.
ECR for Telecommunication Equipment Vendors
The ECR specification offers a standardized way of estimating the energy efficiency across a vendor's product portfolio in a repeatable and automated way. This can significantly improve the effectiveness of R&D process. Best-practice energy management engineering efforts, such as dynamic power consumption, slow/fast corner component analysis, and voltage/performance regulation, can be regulated at a high level with the ECR methodology. In addition, the ECR provides a common set of terms to express the operational cost of products to customers.
ECR for Government Agencies
Due to their sheer simplicity and direct physical meaning, ECR metrics can be readily employed to set compliance goals and approval programs. When used for this purpose, the metric syntax may change to reflect the authority name, compliance revision and product class, for example:
ECR-2008, Class C1.1 (green label) awarded to qualifying platforms within 25% of the reference metric of 15 Watts/Gbps (or better).
ECR-2008, Class C1.1 (yellow label) awarded to qualifying platforms within 35% of the reference metric of 15 Watts/Gbps (or better).
ECR-2008, Class C1.1 (red label) non-compliant platforms within 45% of the reference metric of 15 Watts/Gbps (or worse).
Forward-looking labels can be defined in accordance to the goals of government certification, environment goals (i.e. CO2 reduction), local business or regulatory needs, i.e. ECR-2010, Class C2.2 (green label) awarded to qualifying platforms within 25% of the reference metric of 8 Watts/Gbps (or better). The metric constitutes the minimum requirement for equipment to be put in service in 2010 and later.
ECR for Standard Bodies and Organizations
The ECR is a commercially proven, turn-key methodology that can be easily adapted for use in telecom-related energy efficiency standardization efforts. For example, in the goal of standardizing the framework of building a datacenter, if the upper-level metric is defined as payload-per-energy unit, every technology archetype (power conversion, cooling, computing, telecom) gets its own efficiency vector. ECR can be used to cover the telecom part of the equation. Likewise, in standardization of the broadband infrastructure, there are consumer and ISP levels of energy consumption; ECR can be used for the aggregation (telecom) portion of the equation.
