Appendix 1: Detailed Emissions Report
Executive Summary The purpose of this appendix is to provide a transparent accounting for the GHG emissions reported in the CECAP report including the scope, boundaries, data sources and activities currently included in the reporting.
In 2018/19, BU’s GHG emissions across all scopes were recorded as 5,880 tonnes of carbon dioxide equivalent (tCO2e) for the year. In 2019/20 this reduced to 4,305 tCOe2 and in 2020/21, 4,230 tCOe2. In 2020/21, the SBT targets for scope 1 and 2 were missed, but the scope 3 target and overall target was met (see below table). Further scope 3 activities are to be defined and methods for the accurate recording of these activities are to be developed.

Introduction
Boundaries
Included in this report are activities that took place between 1st August 2020 and 31st July 2021. Operational activities from BU’s estate (for example, energy emissions) are included and the boundaries of the estate are as defined in the EEMS; “the provision of a fused experience of education, research, professional practice and related support services at Bournemouth University Talbot and Lansdowne campuses, University Centre Yeovil, Chapel Gate sites, Student Village and Unit 5 Drewitt’s Industrial Estate.”
Scopes
In order to fully account for BU’s GHG emissions and identify future opportunities for reduction, activities across scopes 1,2 and 3 need to be accurately recorded. Scope 1 to 3 are defined in the below table. Scopes 1 and 2 are currently recorded fully and the table indicates which areas of Scope 3 are only partially recorded, or not recorded at all. Methods for recording activities that fall under scope 3 are to be defined fully, as recommended by the original CECAP report. Purchased goods and services have been identified as a priority, given the likely amount of emissions and the opportunity for BU to engage with suppliers to reduce these significantly.
Scope Direct/ Indirect Source types
Scope 1 Direct Emissions associated with sources that are owned or controlled by the reporting organisation.
Scope 2 Indirect Emissions from generation of purchased energy Scope 3 Indirect Emissions from activities that occur from sources not owned or controlled by the reporting organisation (upstream/ downstream) Sources examples Recorded in CECAP report

Natural Gas Data sources:
1.Direct manual reads of all billing level meters (kWh converted from m3 or ft3 of gas) 2.DEFRA carbon factors, published July 2020
Results in 2021/21:
1,437tCO2e, an increase from the baseline year (1,345tCO2e) Natural gas is the main heating fuel for the BU Estate.

Factors that are external to the Energy Management System that increase or decrease natural gas usage include the size of the BU estate, the Covid-19 pandemic and the weather. Controllable factors affected by BU’s operational decisions include the amount of onsite renewable/ low carbon generation (GSHPS and the biomass boiler) and the operation and monitoring of the BMS and AMR systems as part of the ISO50001 Energy Management System.
Results in 2021/21:
71.6tCO2e, an increase from the baseline year (69.3tCO2e) LPG is the heating fuel for the Chapel Gate Sports ground. Similar to natural gas, the weather and changes to operations due to Covid-19 have impacted the emissions amount.

However, there are other GHG gases released into the atmosphere during combustion, so it is not carbon dioxide equivalent neutral. There was a decrease in emissions from this source in this reporting year due to a mechanical fault on the boiler which left it inoperational for part of the winter. This would, in turn have increased the Natural Gas emissions. The CECAP suggests an improvement for data capture of this activity, in measuring the tonnes of wood chip delivered and moisture amounts to convert to carbon, rather than heat output.
Results in 2021/21:
4.7tCO2e, a decrease from the baseline year (19.5tCO2e). The amount of electric fleet vehicles has increased, and this has been reflected in the decrease in emissions. During the Covid-19 pandemic, there has also been a decrease in nonEstates fleet usage also.

The change in ventilation has impacted electricity less than natural gas, although there has been an increase in usage in areas that use electrical heating (e.g. EBC) or are mechanically ventilated or use GSHPs. On site renewable generation has also increased. The ISO50001 Energy Management System was used to monitor the on-site usage via the BMS and AMR systems.

The estate by the end of 2020/21 had a 18% larger floor area compared to 2005/06 and 14% increase in floor area compared to the baseline year of 2018/19. The estate at the end of the reporting year 2020/21 was 104,795m2 (compared to 91,857m2 in 2018/19); during the period of October 2020 to February 2021, the size of the estate was even larger (114,025m2 in October and November and 113,731m2 in December and January).
