About us Our Vision Protecting the environment

Our environmental responsibilities

As a sustainable business, we've always put protecting the environment and reducing our impact upon it at the heart of our activities. As a supplier and distributor of over a third of the Island's energy, we wholeheartedly support the Government’s carbon neutrality ambitions.

Our responsibility is three-fold:

  • We act to reduce our impact on the drivers of climate change through our internal business activities
  • We supply our customers with low-carbon power
  • We help customers and the Island as a whole to use energy more efficiently

Our environmentally friendly energy mix

We import 95% of Jersey's energy requirements from low carbon nuclear (64%) and hydro (36%) sources in France through three undersea supply links. These links are known as Normandie 1, 2 and 3.

Together, they give the Channel Islands access to 263MW of low carbon power of which Jersey has access to 202MW. This importation strategy helped the Island achieve a 47% reduction in emissions between 1990 and 2017.*

Inspiring a zero-carbon future

But we know there is more to be done. We now want to inspire a zero-carbon future by intensifying our efforts to replace gas and oil for heating and cooling, encouraging electric transport and providing customers with energy-saving technologies.

In 2019, we began introducing locally-generated solar PV power on to the grid to give all Islanders a share in local renewables. We also invest in research of large-scale renewable technologies such as tidal and wind power.

As a business, we've undertaken several initiatives to reduce our environmental impact from our day-to-day activities.

Reducing our emissions

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 into 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 equivalent amount of global warming. This way, a carbon footprint consisting of lots of different greenhouse gases can be expressed as a single number.

Our historical emissions

The below table gives information on JE's GHG emissions. All emission data is displayed in tonnes of CO2e:

Emission source 2019-20 2018-19 2017-18
Combustion of fuel & operation of plant 1,226 3,151 1,702
Electricity transmission and distribution losses 512  438 525
Electricity importation 13,432 12,901 11,691
Gross Emissions 15,170 16,490 13,981

Company's intensity measurement

Company intensity is measured in grams of CO2e per kilowatt hour (g CO2e kWh) of distributed electricity*.

In the year ending September 2020, it was 24g CO2e/kWh, one-tenth that of the UK’s supply calculated at 233g CO2e/kWh** and much less than local oil (298g CO2e/kWh)*** and gas (241 g CO2e/kWh).***

* Distributed electricity includes transmission losses of the electricity through our network and internal usage.

Our Environmental Management System

We have an Environmental Management System (EMS) which covers air and water-based emissions, waste minimisation, water use and energy efficiency and we use the stringent standards of the British Safety Council (BSC) Five Star Environmental Audit to benchmark ourselves and ensure continual improvement.
