Carbon Reporting

At Guernsey Electricity we are committed to reducing our carbon intensity for the benefit of the island. This means staying not only abreast of but ahead of international best practice for reporting.

As a signatory of the Kyoto Protocol - the UN Convention on Climate Change's framework for Greenhouse Gas (GHG) emissions mitigation, adaptation and finance - Guernsey has committed to tackling climate change and a ‘80% reduction of carbon emissions on 1990 levels by 2050’.

Guernsey Electricity is fully supportive of this target. As a business we have already taken steps to reduce our emissions by 66% on our 1990 levels. In the 2017/18 financial year 86% of the energy supplied by Guernsey Electricity was low carbon, supplied from hydroelectric and nuclear plants through the cable link with France.  We are also taking measures to further reduce our carbon emissions, including installing community scale solar panel arrays and phasing electric vehicles into our fleet. 

In April 2018 Guernsey Electricity launched a new reporting methodology, which has enabled us to disclose all of our greenhouse gas emissions involved in the company’s activities directly under the control of Guernsey Electricity. Currently, supplier and contractor emissions are not included in our reporting.

We took the proactive decision to introduce a new carbon emissions reporting process to align the company with the best practice guidelines and requirements of the Paris Agreement, which is the due to replace the Kyoto Protocol in 2020.

The process also now enables us to break our carbon reporting data down, as shown in the diagram below, into direct emissions sources (such as fuel used in energy generation and company vehicles) as well as indirect emissions (such as imported electricity). This has been possible through the use of the international accounting tool, the GHG Protocol and the DEFRA 'Environmental Reporting Guidelines: Including mandatory greenhouse gas emissions reporting guidance June 2013'. Our methodology and reporting process is reviewed annually by external GHG reporting specialists.

Note

Emissions are calculated for the financial year running March to April. 

The figures stated are Carbon Dioxide equivalent intensity, which means that for every unit (kWh) of energy produced in a single quarter, an average of the figure shown equals the grams of CO₂e emitted.

Emissions of the greenhouse gases; carbon dioxide, methane, nitrous oxide and fluorinated gases (hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride) are all included in our reporting, they are all presented in the form of CO₂e.

Emissions associated with imported energy, are calculated using figures published by EDF and include both direct and indirect emissions - the carbon intensity of hydroelectric is 6 gCO₂ e/kWh and nuclear energy is 4 gCO₂ e/kWh.

Our emissions are broken down into the following scopes, as defined by the Greenhouse Gas (GHG) Protocol:

  • Scope 1: Fuel consumed in GEL’s Vale Power Station to generate electricity, fuel used and fugitive emissions across our our distribution network, and our company vehicles and plant.
  • Scope 2: Electricity consumption in networks, electricity transmission and distribution losses and electricity consumed in GEL’s office buildings.
  • Scope 3: Electricity lost in the transmission across the Channel Islands Energy Group (CIEG) transmission network.
  • Gross Emissions
