Introduction
0.1 General
This document shows how an organization that manages its energy performance can use that processto achieve net zero energy (NZE). It explains what is meant by NZE and how an energy managementsystem (EnMS) in accordance with ISO 50001:2018 can be implemented to achieve maintain andin new and retrofitted facilities which is beyond the scope of ISO 50001. In addition it is designed to plement organizational action to achieve net zero carbon (NZC).
criteria it remends for showing that it meets NZE or NZC goals. Many jurisdictions use the twoterms interchangeably and others promote one goal over the other as discrete choices. This document attempts to reconcile these definitions. It distinguishes between several different scopes and boundariesfor these different net zero goals and their targets which are increasingly effective at reducing energyEnMS be structured to allow continual improvement from lower targets to higher ones. and greenhouse gas (GHG) emissions and correspondingly more difficult to achieve. It suggests that an
A number of countries around the world have pledged to achieve a net zero goal and many more havemitted to significant energy savings and carbon reductions in their societies.1Zl Meeting these mitments over the ing decades requires accelerated improvements in energy management.
Many organizations are undertaking specific actions to reduce their carbon emissions by better management of energy including targeting NZE. These actions may include:
- measuring managing and minimizing energy use to achieve NZE through operations;- designing and constructing new buildings or other facilities to meet a target of NZE;- retrofitting existing buildings to improve their performance toward or beyond NZE;-integration of renewable energy e.g. photovoltaics (PVs) solar water heating geothermal energy on-site wind turbines;coordinating robust energy management with other sustainability initiatives to achieve or surpass
NZC.
The EnMS conforms to ISO 50001:2018. This document remends establishing specific quantifiable This document shows how an EnMS can include objectives such as specified levels of NZE and NZC.targets for energy consumption that can serve as a pathway to NZE. Use of this document should enablecloser harmonization of claims of NZE within and between organizations and across regions and nations.
