Meeting efficiency targets: reducing CO2 emissions

The energy market and energy policy are subject to constant change and present companies with new challenges time and again.

In order to meet ambitious political targets, it is therefore necessary to comply with ever stricter standards and laws. On the other hand, standards are also considered to be state of the art and are of great importance for the solution of many technical and economic tasks. Find out which are the most important energy efficiency standards and how we can help you to successfully implement standards and laws.

Laws and standards

The EU Energy Efficiency Directive

The EU Energy Efficiency Directive is implemented in Austria through the Federal Energy Efficiency Package, which includes the Federal Energy Efficiency Act (EEffG).

Obligations exist under the Federal Energy Efficiency Act for:

  1. large companies (definition > 249 employees and annual turnover > 50 million Euro or balance sheet total > 43 million Euro)
  2. Energy suppliers
  3. the Confederation

Commitments in detail

  • Energy suppliers are required by the Federal Energy Efficiency Act to demonstrate energy efficiency measures corresponding to at least 0.6% of their energy sales to their end customers in Austria. These in turn give their customers (eg. large companies) the possibility of averting a resulting increase in electricity prices by implementing planned energy efficiency measures.
  • According to the Federal Energy Efficiency Act, there are three obligations for large companies:

    1. There are two options to choose from
    a. Four-yearly performance of external energy audits
    OR
    b. Introduction of a certified energy management system, environmental management system or an equivalent state-recognised management system, with regular internal or external energy audit

    2. Continuous documentation of management system or energy audits

    3. Immediate notification of the introduction of a management system or the performance of the energy audit to the energy efficiency monitoring body.

    Energy efficiency measures developed by the large companies must be validated by the monitoring body (method evaluation). If the company's own relevant measures for the energy supplier are not achieved, these can also be acquired from external companies through measure trading.
  • SMEs are exempt from the EEffG and thus not obliged to implement measures, but they can make them available via the trade in measures (trade sheet forms) if they are evaluated.

Carbon footprint

CO2 footprint: significance for customers, investors etc.

For companies, the carbon footprint is an important indicator of their contribution to sustainability and climate protection.

 

The sustainability commitment of companies is also gaining in importance among customers in the manufacturing industry: more and more frequently, they are looking for sustainably produced products and regard the issue as an essential component in their purchasing decisions. The analysis of climate risks in their portfolios is also playing an increasing role among investors, decisions on the purchase of goods are also made on the basis of the eco-balance, and shareholders expect compliance with environmental and climate protection standards.

 

More and more companies are publishing their climate protection activities and their carbon footprint with various reporting initiatives: for example, in the course of reporting to CDP (formerly Carbon Disclosure Project) or GRI (Global Reporting Initiative).

Calculation of the carbon footprint


In accordance with ISO standard 14064 and the guidelines of the Greenhouse Gas Protocol, emissions from three different areas (so-called scopes) are used to calculate the carbon footprint.

Scope 1: Emissions from the operation and use of the company's own vehicle fleet and the use of self-generated energy.

Scope 2: Climate impact of purchased energy, i.e. electricity, heating and cooling.

Scope 3: CO2 emissions from business travel and other purchased services and products.

 

In order to improve the emissions balance and emphasise the commitment to sustainability, green electricity certificates of origin or emission reduction certificates from climate protection projects can also be used.

ISO 50001

Energy management according to ISO 50001

With the use of an energy management system, e.g. in accordance with the international standard ISO 50001, the company can fully exploit its energy potential.

The main objectives of the ISO 50001 standard are to increase energy efficiency and reduce energy consumption and CO2 emissions.

The standard is not subject to mandatory certification. However, certification is becoming more important as a result of the new EU Energy Efficiency Directive and the national efficiency laws derived from it.

 

Experience with the introduction of energy management in companies and organisations shows that energy savings of up to 10 % are already triggered by the introduction process. And this without having to "take a lot of money in hand", because the structured approach to the analysis of the entire energy use reveals many wastes. These can often be remedied by simple organisational and control measures.

The overall responsibility for the energy management system lies with the management. This ensures that the management really stands behind the introduction of the system and also releases the necessary resources.

Energy efficiency in production – in reality

Energy-efficient production means more than simply reducing energy consumption, CO₂ emissions, or costs – it also involves linking energy and production data in order to analyze and optimize not only energy consumption but also the energy productivity of machines, plants, and processes. These measures provide the opportunity to achieve all-round improvements in process productivity and efficiency.

Transparent visualization of energy data

The question:

Do two similar machines consume different amounts of energy?

 

The answer:

Measuring devices are installed on both machines to record and evaluate the consumption data. The analysis shows that machine A requires more energy for vacuum operation and the conveyor belt requires more electrical energy.

 

The solution for greater efficiency:

A leakage in the vacuum system is identified and repaired. A motor with a defective bearing is identified on the conveyor belt, and it is replaced with a more efficient motor during its next maintenance.

Assessing and analyzing the energy efficiency of machines

The question:

I would like to purchase a new machine. How can I compare the consumption performance of the machines on offer and reduce energy consumption that does not contribute to added value?

 

The answer:

Using an appropriate solution, energy consumption can be ascribed to the individual energy operating states (off, standby, ready for operation, in operation) and evaluated and compared accordingly.

 

The solution for greater efficiency:

Machine suppliers can provide their customers with an energy consumption profile (standardized acceptance form) during the purchasing phase. Actual energy consumption on-site can be analyzed by means of a reference measurement. Using key energy performance indicators (EnPI) and benchmarks, all machines can be evaluated continuously and comprehensively and appropriate optimization measures can be implemented, e.g., adaptation of the standby mode.

Meeting requirements, identifying savings potential, optimizing contracts

The question:

How can I identify the savings potential in my operations, optimize my contract with the energy supplier, reduce my tax payments, and benefit from state subsidies?

 

The answer:

Introduce a certified energy data management system in production that reports and archives energy data in accordance with legal requirements (e.g., ISO 50001, German Renewable Energy Act).

 

The solution for greater efficiency:

Identifying the major energy consumers allows you to avoid energy peaks. An automated load management system can automatically shut down systems and make them available again. Forecasting the expected load profile enables you to negotiate an optimized contract with the energy supply company. Transparent energy consumption helps make personnel more aware of energy efficiency within the company, and energy efficiency measures and targets such as the annual increase in energy efficiency can be tracked and verified.
