How does ISO 50001 differ from ISO 14001?
ISO 50001 focuses on energy management, whereas ISO 14001 Environmental Management Systems (EMS) helps you manage your total environmental impact including waste disposal and minimising the effect on surrounding land, air and water supplies.
ISO 14001 does touch on energy but does not give detailed specifications for an energy management system. The two standards complement each other well.
A Word About ESOS
ESOS is the UK Government’s Energy Savings Opportunity Scheme.
If your organisation meets the qualifying criteria for ESOS (generally 250 or more employees or an annual turnover of €50 million/£38,937,777) then you must be ESOS compliant by 5th December 2019.
This means you must complete and submit to the Environment Agency a detailed report which analyses your energy usage and identifies opportunities for savings.
However, if your ISO 50001 certification covers all your energy usage, then this means you are compliant with ESOS requirements.
