Implementing an energy management system (EMS) in line with ISO 50001 can help identify often unsuspected sources of energy savings. And in so doing, contributes to improving the organization’s environmental performance.
La lutte contre le changement climatique est une clé de voûte de la transition écologique. Limiter la hausse des températures à 2 °C d’ici à 2100 implique d’éradiquer progressivement les énergies fossiles et de les remplacer par des énergies renouvelables. Or, celles-ci ne couvrent encore que 14 % de la consommation d’énergie finale en France. En attendant qu’elles montent en puissance, et en préalable, il est impératif d’améliorer l’efficacité énergétique des équipements, des procédés et des bâtiments : il faut consommer moins, à service rendu égal.
European regulations require companies with over 250 employees or sales in excess of €50 million to carry out energy audits every four years. At the same time, the 2018 ELAN law requires occupants of 1,000 m² buildings housing tertiary activities to save 40% energy by 2030 compared with 2010, then 50% by 2040 and 60% by 2050.
Bien choisir et construire ses indicateurs de performance environnementale
Le GHG Protocol (Green House Gas Protocol) est le plus ancien référentiel de comptabilisation des émissions de gaz à effet de serre (GES). Il a servi de base à la norme NF EN ISO 14064 « Quantification et rapport des émissions de gaz à effet de serre pour les organisations ». Il distingue trois grands groupes d’indicateurs tout au long de la chaîne d’approvisionnement :
- les émissions directes (scope 1) ;
- les émissions associées à la production d’électricité, de chaleur ou de vapeur importée ou achetée (scope 2) ;
- les émissions résultant des activités de la société, mais qui proviennent des fournisseurs (scope 3).
To help you get up and running, we strongly advise you to set up an energy management system (EMS). This methodical management focuses above all on energy sobriety and efficiency, according to the adage: “The best energy is the energy we don’t spend. The application of voluntary standard ISO 50001 facilitates this exercise, as it explains how to organize yourself to ensure that energy savings materialize over the long term. The text was revised in 2018 to reflect the state of the art in collecting consumption data and measuring energy performance improvements.
Management de l’énergie : des résultats quantifiables grâce à l’ISO 50001
A strategic management tool, like the EMS for the environment with ISO 14001, the EMSn starts with an assessment of the various energy uses. It involves deploying a metering plan (measurement, data collection, analysis, monitoring), which can help identify areas for improvement, such as taking energy efficiency into account in product and equipment purchasing. Once the simplest, most easily cost-saving measures have been implemented, the EMSn can be used to move on to more elaborate operations covering the entire production system. As all the results are quantifiable, the advantage of an EMSn is that it enables you to prioritize the various possible actions according to your company’s financial capacity, context and objectives.
A voluntary approach, the SMEn can lead to AFAQ ISO 50001 certification, which proves to third parties that the effort undertaken is not a self-declaration and will indeed lead to energy savings, thanks to the best practices identified in the standard. Please note: large organizations with current ISO 50001 certification do not need to carry out a regulatory energy audit.
