Energy and carbon are two of our biggest environmental impacts. Heightened environmental awareness, costs, regulation and advances in technology are helping us to develop new programmes to improve efficiency and reduce carbon emissions.
The use of energy throughout our business is re-evaluated each year. For Marston’s, improvements in energy utilisation through green technology, building design and behavioural change are intended to drive significant savings in emissions.
Electricity and gas usage are dominant. As our food sales increase it becomes more difficult to decrease our absolute energy use year-on-year. However, we are reviewing other ways to mitigate these emissions such as moving to renewable energy or offsetting.
Gas and electricity usage in managed pubs is monitored and this data is validated. Energy use is collected by Automated Meter Readings, and also from manually read meters. This data is cross checked against expected consumption.
(including Scope 1 and 2, and Scope 3 emissions)
|Electricity and gas||71,297||79,491|
|Petrol and diesel||8,866||12,031|
|CO2 tonnes per £100k (turnover)||16.97||12.05|
|Scope 1 and 2||346,892||441,564|
1. We report on all the measured emissions sources required under the Companies Act 2006 (Strategic Report and Directors’ Reports) Regulations 2013.
2. Data collected is in respect of the year ended 30 June 2021, in accordance with the Streamlined Energy and Carbon Reporting regulation.
3. Total gas consumption compared to last year reduced by 3% which reflected the temporary shutdown of our pubs during the winter. Electricity consumption decreased by 18%, usage for lighting fell during the lockdown. Fuel usage fell by 26% due to the periods of lockdown when deliveries to the pubs were suspended. Fuel usage became a scope 3 emission from November to June 2021 following the commencement of CMBC.
4. To reduce the energy consumed we focus each year on various initiatives. Our catering equipment is sourced to increase efficiencies including fryers that filter oil to increase oil life, and high efficiency chargrills. All of Marston’s cabinet refrigerators purchased are high efficiency hydrocarbon units. We install LED lighting in all the internal areas and use integrated movement sensors in our back of house areas, reducing the operational hours of lighting. We also fit voltage optimisation in all of our new-builds and have retro-fitted them into other sites across the estate.
5. The Greenhouse gas emissions intensity ratio has been distorted by the pub lockdown, and the reduced turnover of the business. While we have taken steps to reduce energy usage in our pubs during the lockdown, we still had to maintain refrigeration, heating and lighting, particularly in those pubs where the manager lives on site.
