What is Newcastle University doing to achieve Net-Zero?

As a world-leading institution, Newcastle University has always recognised its responsibility to protect the natural environment – whether through large-scale sustainability initiatives like the Climate Action Plan, or through trailblazing research on marine biomes, extreme weather, and more…

The Sustainability Team at Newcastle University was launched in 2006, and the team’s remit has grown ever since! There are now eight key themes that their work focuses on, including waste, travel, biodiversity and carbon. Their work ranges from large-scale infrastructure projects, to engaging colleagues and students through events and certifications.

Read on to find out about some of the major developments facilitating decarbonisation on campus, ran by the Sustainability Team in collaboration with colleagues in Estates & Facilities and across the University.

Declaring a Climate Emergency

Newcastle University declared a climate emergency in 2019, becoming the second UK university to do so. This declaration was influenced by increasing public discourse on climate change, spurred by activist movements such as Fridays for Future and the work of Greta Thunberg.

By 2021, in response to mounting scientific research and national policy developments – such as the UK government’s legally binding net-zero target for 2050 – the University accelerated its own carbon reduction target from 2040 to 2030. A key step towards this commitment also included full divestment of endowment funds from fossil fuel industries.

Climate Action Plan and Net-Zero Target

The University’s net-zero target includes both our direct emissions from on-campus sources like gas boilers and fleet vehicles (known as Scope 1 emissions) and indirect emissions from purchased energy such as electricity and steam (Scope 2 emissions).

Scope 3 emissions, which encompass travel and procurement, are currently excluded from the 2030 target because of less robust methodologies and reporting. Nevertheless, efforts to address Scope 3 are ongoing, including engaging with supply chains and conducting travel surveys.

The Climate Action Plan outlines key strategies, including reducing energy consumption, increasing renewable energy generation and transitioning away from fossil fuels.

Solar Photovoltaics on Campus

In 2023, Phase 1 of the University Solar Photovoltaics (PV) project began. As a city-centre campus, we have limited space for solar panels. Rooftop installations provide an ideal solution, maximizing sunlight exposure without taking up valuable ground space.

Phase 1 concluded in 2024, with the installation of panels on the Cochrane Park Sports Pavilion, the fourteenth building to support solar PV. Other buildings covered by Phase 1 included:

  • Frederick Douglas Centre
  • Urban Sciences Building
  • The Catalyst
  • Park View Student Village (6 buildings)
  • Sports Centre (2 buildings)
  • Philip Robinson Library
  • Henry Daysh Building

Over a period  of less than two years, the panels have generated 71.5 MWh of electricity and have saved 147,000 Kg of carbon from being emitted. This is equivalent to charging an electric vehicle for nearly 4.7 million miles and avoiding the emissions of approximately 147 transatlantic flights.

Our largest and most productive array is at the Sports Centre which at its peak of 150kW, can generate the entire electrical requirement of the building.

Phase 2 is now underway, seeing installations already finished on the Bedson and Stephenson buildings, and many more to come.

Merz Court CHP Plant and District Heating

The biofuel Combined Heat and Power (CHP) plant at Merz Court was installed as part of the Stephenson Building project, showcasing an innovative approach to sustainable energy.

At the heart of Merz Court’s heating system is its energy centre, a powerful and efficient plant room tucked away in the building’s basement. Recognising its impressive potential, the University saw an opportunity to divert excess energy to the Stephenson Building. This meant that Stephenson would not require its own energy centre, thereby reducing unnecessary emissions from both construction activity and excess energy production.

The heating plant is designed to provide very-low carbon energy to a growing network of buildings via an underground pipe system including:

  • Henry Daysh Building
  • Stephenson Building
  • King Edward VII Building
  • Percy Building
  • Old Library Building

The CHP is projected to provide approximately 25% of the University’s electricity base load. The approach links back to the Climate Action Plan, investing in district heating and reducing emissions through centralised renewable energy sources.

Future Sustainability Projects
Exciting developments are on the horizon as Newcastle University prepares to launch the next phase of its net-zero strategy, focusing on a more tailored building-by-building approach. This includes working closely with external consultants to refine business cases for various projects.

Engaging the University Community
Alongside larger infrastructure projects, achieving net-zero also relies on the involvement of the wider University community:

If you are a colleague, you can participate in sustainability programmes like the LEAF lab accreditation for wet labs, or the Green Impact award for staff teams. Students can attend free Dr Bike repair events, join the Sustainability Network, or become Green Impact auditors. If you are interested in joining any of these programmes, please see the Sustainable Campus website or contact: sustainable-campus@newcastle.ac.uk

For a better breakdown of the projects the Sustainability Team do across campus, check out our brand-new Sustainability Campus Map.

A big thank you to the Sustainability Team – Matt, Hannah, Luke, and Jordan – for their help in writing and compiling information for this article. I’d also like to thank Tony from the Capital Developments team for providing data and figures, as well as Peter and Sam for their involvement in the Solar PV video.

Combining energy and sustainability: upgrading Newcastle University’s Merz Court Energy Centre

Heating and powering our campus is one of the University’s largest sources of carbon dioxide emissions and so work to improve the efficiency of these systems is very effective at reducing our institution’s impact on the environment.

To this end, a major project the University is currently undertaking is the installation of a Combined Heat and Power (CHP) plant in Merz Court’s Energy Centre. This new infrastructure has required the work of a variety of University teams alongside multiple external companies to plan this major energy upgrade and coordinate its installation. Now, as the completion of the project is coming into view, this blog will explore how CHP systems work, and how the University’s new power plant is set to save significant emissions for years to come!

What impact will this have?

Combined heat and power or ‘cogeneration’ plants increase efficiencies by utilising the waste heat generated when creating electricity to warm buildings. These systems are especially effective when hooked up to district heating networks – where one energy centre powers multiple buildings. So, when different teams were coming together to plan the power supply for the newly refurbished Stephenson Building, an upgrade to our existing district heating network centred in Merz Court fit the bill nicely.

Now, after lots of hard work from many colleagues across the University, the new 27-tonne CHP engine has been successfully installed in Merz Court’s Energy Centre! On top of the improved efficiencies of cogeneration systems, the University’s new CHP uses greener biofuel to generate its heat and electricity – greatly reducing carbon emissions as compared to conventional systems.

Additionally, the CHP’s impact on carbon savings will be further reinforced as Merz Court Energy Centre’s district heating is connected to a whole swathe of the campus, including the:

  • Henry Daysh Building,
  • Stephenson Building,
  • King Edward VII Building,
  • Percy Building,
  • Old Library Building,
  • And Merz Court itself!

Across these buildings, the CHP’s lower carbon factor energy will pull down our campus’s carbon emissions by thousands of tonnes a year. Additionally, after recent progress, the first batch of biofuel has now been delivered and we’re happy to announce that the new system will be generating power for the next heating season!
