We report our data voluntarily to the HESA Estates Management Record. This data is reported without context and it can be difficult to assess universities’ performance without factors such as size, research intensity, construction activity and student accommodation ownership being taken into account.

The data reported below includes our HESA submission, but also additional information to help contextualise figures in the activity of the University.

Scopes 1 and 2 carbon emissions

Scope 1 emissions are those that we are directly responsible for, for example the emissions from our fleet of University vehicles and the gas we use in our boilers for heating buildings. Scope 2 emissions are mainly those produced through the generation of the electricty we use on campus.

Scopes 1 and 2 emissions are usually reported together.

Total emissions

Reporting through the Higher Education Statistics Agency (HESA) requires the use of gross emissions using UK grid average carbon intensity.

Because the University purchases 100% renewable electricity, the gross (ie, grid-average) figures do not accurately portray the carbon intensity of our electricity supply. The net figures therefore highlight the contract-specific emissions associated with the University’s procured electricity. Over time (from when the contracts started in 2020), the gross and net figures reported will diverge so we include both figures to show the impact of our electricity purchasing choice on our carbon emissions.

Waste and recycling

The University produces a wide variety of waste, from normal office and commercial waste associated with most large organisations, to residential waste at our residences, food waste from our commercial outlets, and hazardous, clinical and radioactive waste related to research. These figures are for waste and disposal by tonnage; for Scope 3 emissions relating to waste, please see above.

Waste totals

Waste by source (tonnes)

We are committed to reducing the amount of waste produced from our activities and increasing the percentage of waste that is reused and recycled.
 
We collect and report on waste produced as a result of University activities holistically:

• Waste generated directly from our activities, for example waste generated on campus, at the AMRC, and from our commercial activities. Waste generated by the Students Union is also also included in this total.
• Waste generated indirectly from our activities, for example waste generated from residents at University managed accommodation and the waste generated by our construction activities.
• Other works waste is waste arising from capital works, for example construction activities. These works can have a large impact on our waste arisings and the years where we have undertaken significant capital construction and refurbishment projects result in a significant increase in waste arisings (for exmaple in 2017/18 and 2018/19). We only report these waste arising in the Other Works category.

We chose to take this approach to reporting as it provides a complete account of our activities and impact.

Waste disposal

Non-residential waste: direct waste from institutional activities (tonnes)

Our policy is to only send waste to landfill when we are legally obliged, for example asbestos. The table below provides an overview of the organisation’s performance, listed in order of environmental preferability.

Percentage of waste recycled / recovered	94.6%	55.2%	92.6%	95.2%	94.7%

*In 2018/19 a substantial amount of asbestos was found during a building demolition, which legally has to be sent to landfill. This is why our landfill total for this year is much higher than the long terms average.

Residential waste: indirect waste from student accommodation (tonnes)

The University owns and manages residential accommodation. Our residents are provided with general waste bins, recycling bins and food waste bins, which means all the waste generated by our residents is diverted from landfill. 

	2017/18	2018/19	2019/20	2020/21	2021/22

Fleet

Fleet decarbonisation

We are continuing to decarbonise our fleet through the introduction of electric and hybrid vehicles where possible.

The University operates a number of larger and specialist vehicles, such as tractors, refrigerated units and trucks with tail lifts, which it is currently not possible to replace with electric vehicles. When these vehicles come to the end of their operational life they are being replaced with Euro 6 Class (low emission) vehicles.

As of February 2023, of the 23 vehicles in the fleet not electric or hybrid, 15 have Euro 6 Class engines.
