Energy and carbon

Energy and carbon are two of our biggest environmental impacts. Heightened environmental awareness, costs, regulation and advances in technology are also driving Marston’s to develop new programmes to improve efficiency and reduce carbon emissions. The use of energy throughout our business has been 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.

Net Zero Roadmap

We are a signatory to the Hospitality Zero Carbon Forum, established to decarbonise the sector at pace. Together with 18 other hospitality organisations and backed by UK Hospitality and BBPA, we have created a team of leading sustainability experts to combine resources to systemise adoption of emission reduction initiatives and publish an industry-wide net zero roadmap by September 2021.

The forum is pledging to act now to achieve net zero carbon targets faster, more efficiently and cost effectively than acting alone. We believe this approach could act as a template for future industry sector collaborations in the UK and globally.

Carbon data

Electricity and gas usage are dominant. As we move towards higher food sales and increased efficiency it becomes increasingly difficult to decrease our absolute energy use and greenhouse gas emissions year-on-year. However, we are reviewing other ways to reduce these emissions like moving to renewable energy or offsetting.

Gas and electricity usage within the breweries and managed pubs is automatically monitored and this data is validated continuously. Energy use is collected by AMR, and also from manually read meters. This data is cross checked against expected consumption. Fuels used by delivery trucks and drays is recorded and validated against expected values. Other emissions are estimated and are relatively insignificant.

Managed and franchised pubs

Individual pubs

Our managed pubs represent the largest contributor to the carbon footprint under our direct control and we are committed to reducing our energy and associated emissions. The table below represents average energy consumption and CO2 emissions per pub within our managed portfolio for which we consider the data collated to be reliable over the previous six years.

Energy & Carbon reduction initiatives

Throughout Marston’s portfolio of pubs food sales have steadily increased. As such the energy demand of our kitchens has also increased. To increase efficiencies and minimise costs, Marston’s have worked on the catering specification to reduce the energy consumption and increase life expectancy of catering equipment. Innovations have included highly efficient fryers that filter oil to increase oil life, and high efficiency chargrills.

Traditional fluorocarbon refrigerants are ozone depleting or have a significant global warming impact. As such Marston’s are committed to reducing the use of these HFC’s. All of Marston’s cabinet refrigerators purchased are high-energy efficiency hydrocarbon units, which are manufactured in the UK.

LED Lighting
Lighting makes up a significant proportion of the electrical consumption of a pub. We have installed LED lighting to all internal areas across the whole of our pub estate. LED lighting consumes 80% less energy than tradition incandescent lighting. In back of house areas we have installed LED lighting integrated PIR occupancy sensors, reducing the operational hours of the lighting.

Voltage Optimisation
Voltage optimisation increases the efficiency of electrical equipment, whilst also preventing electrical surges. We have installed voltage optimisation in all of our new-builds and have retrofitted to over 100 sites. The units are more efficient and have a considerably reduced embedded carbon footprint, meaning carbon payback is reduced by 17 per cent

A BREEAM assessment uses recognised measures of performance, which are set against established benchmarks, to evaluate a building's specification, design, construction and use. The measures used represent a broad range of categories and criteria. They include aspects related to energy and water use, the internal environment (health and well-being), pollution, transport, materials, waste, ecology and management processes.

Many of our new-builds are now built to Breeam Standards; many to Breeam Very Good and one Breeam Excellent.

Case study: BREEAM Excellent New Build - Blaina Wharf, Newport

Blaina Wharf, Newport Blaina Wharf successfully achieved BREEAM excellent. Photovoltaic panels have been installed to generate renewable electricity from the sun’s energy. Air Heat Source Pumps have been installed, which transfer heat from the atmosphere outside to inside the pub. The lighting is provided by LED that uses approximately 80% less energy than conventional lighting. Fresh air is used to cool beer when temperatures are low enough outside. The building has been constructed adhering to the BREEAM excellent standard, ensuring the environmental impacts of the building are minimised during its life cycle.

Energy Heroes

Energy Heroes

Employee engagement and behaviour change has a great impact on energy and water consumption, empowering our employers is key to reduce our environmental impacts. Environmental training is provided to our pub teams via our training platform Talent Academy Online and is available to all sites where we are responsible for utilities.

Tenanted and leased pubs

Our tenants and lessees are responsible for the energy used in the pubs they operate. However, we aim to support their efforts in energy and carbon management by the transfer of our knowledge and experience. Through our online portal – “My Marston’s Online” - we offer information on energy saving strategies. We promote our tenants to install energy efficient equipment, where possible we extent procurement arrangements to our tenants so they can benefit from energy saving solutions. We are currently investigating innovative finance solutions to assist with the implementation of measures and will be offering training and support.

Marston’s Rapid Electric Vehicle Charging Network

One of the biggest private networks Europe

We have reached our next environmental milestone after completing the installation of rapid EV chargers across 100 pubs in partnership with Osprey Charging.


We have committed to installing rapid chargers at 200 sites and have recently completed our 100th site, making our network one of the biggest of its kind in Europe. The chargers are powered by 100% renewable energy with up to three cars able to charge at any one time. The rapid chargers can charge an EV with 80-100 miles in around 30 minutes, depending on the type of car and way it is driven. The charging dwell time is perfect for our model, with drivers able to top up while they enjoy a coffee, light bite or meal in one of our pubs. As an early adopter of EV chargers we are able to secure electric grid capacity, future-proof our sites and attract the fast-growing EV population.

Usage is in line with the national average and we have seen positive media and public reaction to the charging experience, locations and quality of food and service in our pubs.

Water management

Water consumption is core to operating our business. Water, wastewater and associated emissions have significant environmental impacts.

Our pubs use water for in our kitchen for preparing food and cleaning. Within our managed pub and franchised portfolio we operate water management systems which drive significant improvements in efficiencies.

Marston's Water - Self Supply

Marston's Water

On 1st December 2017 Marston’s Water was launched. Supplying water to our own properties gives Marston’s more control over water usage and allows us to drive forward with saving initiatives.

The new open water market launched in April 2017 and is the largest of its kind in the world. The market allows eligible companies and other organisations to self-supply and manage their own water retail services, providing an alternative to using a separate retailer and the additional costs that might entail.

Marston’s was the 3rd company in the UK to be granted a water-self supply licence by Ofwat in the new water market.

To date, Marston’s have switched over 1,778 water and wastewater supply points to Marston’s Water. Marston’s now uses a total of 33,601 m3 per day. Since the launch, we have saved 162,000 pints of water a day by driving water saving initiatives.

Marston’s PLC hold a Water Supply and Sewerage Licence limited to Self-Supply (Licence Numbers: 055/2017/WL & 054/2017/SL). We have been operating in the Open Market since December 2017.

Marston’s PLC only supply sites in England where water and sewerage services are our responsibility. Our licence does not cover Franchised or Landlord supplied sites. Managed English pubs that are included in this Licence can be found here: https://www.marstonspubs.co.uk/pubs/finder/.

For any enquiries regarding sites that Marston’s PLC supply, please contact marstons@waterscan.com. As part of our licence obligation, we will provide a live list of sites to Ofwat once every quarter.

Waste management

A Zero waste to Landfill Business

At Marston’s, we understand the importance of managing our waste responsibly. Food waste, glass bottles, plastics, cardboard and cans are all part of our everyday lives, and within our industry we see this waste on a much larger scale. The UK catering industry produces 3.4 million tonnes of waste every year, and we at Marston’s generate around 64,000 tonnes through our breweries, pubs, restaurants and lodges. As a company, we look to avoid, reduce and reuse our waste, but where that is not possible we aim to recycle as much as we can. In 2018, we became the first zero waste to landfill pub group, two years before our 2020 target.

Since 2016, we’ve been working in partnership with UK Waste Solutions and our overall group recycling rate has increased to 88%. We are proud to be leading the way in our sector and continue to focus on innovation to drive further improvements.

Our success got external coverage in the Express & Star – https://www.expressandstar.com/news/business/business-picks/2018/09/11/marstons-achieves-zero-waste-to-landfill-goal/

Focus on our Pubs and Inns

Approximately half of our waste is generated in our 1,000 managed and franchised pubs. We recycled 76% in 2019 and continued to rationalise waste and recycling specifications at all our pubs. 98% of our sites are recycling glass and 97% have a dry mixed recycling service for paper, cardboard, plastics, tins and cans. Of our pubs with a food offer, 82% were recycling food waste, equating to 4,800 tonnes diverted from energy from waste.

Our ongoing ‘Wise up to Waste’ awareness campaign is designed to encourage our teams to think before they throw, so more of waste can be recycled and we can reduce our impact on the environment further. Our engagement tools include; posters, internal labels, recycling league tables, social media and competitions. Take a look at our educational video which highlights the importance of correct segregation and what happens to our waste when it leaves our pubs.

Single-use plastics

We continue to show innovation and drive cultural changes throughout the business to avoid and reduce single-use plastics. Highlights include;

  • Removing single-use water bottles from hotel rooms – saving half a million bottles annually
  • Switching to paper straws – 76% reduction in straw usage vs last year
  • Removing plastic stirrers completely from our estate
  • Identifying closed-loop plastic solutions such as rolling out recycled plastic furniture into our pub gardens

Case study: Beer Garden Innovation

The Sun in Romsley has a great outdoor garden area that’s perfect for summer drinks and al fresco dining, but it was due a makeover.

The result is a first-of-its-kind for Marston’s – a redesigned space made from mixed plastic waste that would otherwise be sent to landfill or incineration. With support from recycling firm Plastecowood, we’ve turned our plastic waste into plastic lumber for the garden’s walkways, fences and new raised patio area.

Jonathan Davies, Waste and Recycling Co-ordinator for Marston’s commented, “We are committed to contributing to the circular economy and plastic waste from our pubs in Yorkshire and the North East of England makes its way into Plastecowood products. Such circularity is key to making the transition to a more sustainable society. By purchasing products made from 100% recycled plastics we are helping to build a steady market for such materials, ensuring the continuation of recycling operations and preventing these materials from ending up in landfill”.

Long-term sustainability is always a priority, actions taken over the last year to improve recycling efficiency and reduce vehicle movements to and from our pubs include;

  • Installing 190 cardboard balers in our pubs. The units compact cardboard into dense bales resulting in improved segregation, space saving for our pubs and reduced vehicle movements for collections
  • Backhauling used cooking oil on our drays. Backhauling has the advantage of increasing storage space at pubs and reducing emissions from transport. We recycle approximately 800 tonnes of used cooking oil annually
