Protecting the environment and lessening our impact upon it are fundamental to sustainable business. As a supplier and distributor of power, our responsibility is three-fold: to act to reduce our impact on the drivers of climate change through our internal business activities; to reduce that of our customers by supplying them with low carbon power and to help customers and the Island as a whole use energy more efficiently.
We have already virtually de-carbonised Jersey's electricity supply which has helped Jersey reduce its overall carbon emissions by 40% since 1990 down 240kt from 600kt in 1990 to 360kt in 2015* by switching from on-Island generation using oil to imported low carbon supplies from France via a network of subsea interconnectors.
Normandie 3 was installed in 2014 and Normandie 1 in 2016. Combined with the existing Normandie 2 cable (2000), they give the Channel Islands access to 245MW of low carbon power and enable us to meet the Jersey's entire demand for electricity from guaranteed low carbon supplies from nuclear (66%) and hydro (34%) sources. We also invest in research into large scale renewable technologies such and tidal and wind power and in 2018 we announced plans to enable small, pilot ground-mounted solar farms with the guarantee of long-term purchases agreements.
As a business, we have undertaken several initiatives to reduce our environmental impact from our day-to-day activities. The States of Jersey gave us ECO-ACTIVE Business Leader status in April 2012 following a British Safety Council Five-Star environmental audit. The audit provided a road map for the implementation of an Environmental Management System (EMS) which covers air and water based emissions, waste minimisation, water use and energy efficiency. As part of that efficiency we installed the largest Photo Voltaic (PV) array in the Channel Islands at our Powerhouse administration office and which generates over 20,000 units a year.
We voluntarily began reporting our Green House Gas Emissions in line with the requirements of the Companies Act 2006 (Strategic and Directors’ Reports) Regulations 2013. We use the DEFRA "Environmental Reporting Guidelines: Including mandatory greenhouse gas emissions reporting guidance June 2013".
The methodology breaks down the emissions in to scopes (please see below); our methodology is reviewed by Mott MacDonald to ensure we are applying it correctly.
The above Regulations and reporting guidelines link in with the Kyoto Protocol, which has six reportable Green House Gases;
- Carbon dioxide (CO2)
- Methane (CH4)
- Nitrous oxide (N2O)
- Hydrofluorocarbons (HFCs)
- Perfluorocarbons (PFCs)
- Sulphur hexafluoride (SF6)
The individual quantities of these emissions are calculated and added up and finally expressed as CO2e or carbon dioxide equivalent, it is a standard unit for measuring carbon footprints.
The idea is to express the impact of each different greenhouse gas in terms of the same amount of CO2 that would create the same amount of global warming. This way, a carbon footprint consisting of lots of different greenhouse gases can be expressed as a single number.
The below table gives information on JE's GHG emissions:
(Tonnes of CO2e)
(Tonnes of CO2e)
(Tonnes of CO2e)
|Scope 1: Combustion of fuel & operation of plant.
|Scope 2: Electricity transmission and distribution losses.
|Scope 3: Electricity Importation (Energy from Waste and Électricité de France)
|Company's chosen intensity measurement: grams of CO2e per Kilo Watt hour (g CO2e KWh) of distributed electricity*
* Distributed electricity includes transmission losses of the electricity through our network and internal usage.
In the year ending September 2018, it was 24g CO2 e / kWh, one tenth that of the UK’s supply calculated at 238g CO2 e / kWh** and much less than local oil (298g CO2 e / kWh)*** and gas (241 g CO2 e / kWh)*** and we expect further reductions in future.

Emissions testing, known as Stack Testing in the industry, is carried by independent accredited contractors who work to National, International and other recognised standards when sampling the air ensuring they meet the requirements of:
The data is interpreted in-house and with experts to ensure that our engines and other plant are running efficiently. We carry out monitoring on all our plant, the frequency depends on whether we have carried out any major modification to the plant.
