Calculating our carbon footprint is essential to developing an effective emissions reduction strategy. In line with the GHG Protocol Corporate Standard, our emissions comprise Scope 1, 2 and 3 across both our portfolio and the Sirius platform.
Our carbon footprint comprises emissions from our portfolio (the assets which we own and operate) and our platform which includes emissions from our operating company, i.e. our head office and Sirius management offices located on our sites.
Due to timing of our utility invoicing and other data collection and in order to provide a complete year’s analysis, our emissions calculations are based on the last full year of available data. Given there have not been any material changes in either the occupancy or the consumption patterns, this data is assumed to be applicable for the 2021/22 financial year. The data used for the basis of calculations of emissions for the leased assets (Scope 3) and for our Scope 1 and 2 for our offices based on our business parks is from 1 April 2020 to 31 March 2021. The data attributed to Scope 1 for our Berlin office is from 1 April 2019 to 31 March 2020. We continue to work with our utility providers etc to bring our emissions data in line with our financial calendar.

Due to the nature of our business model, our Scope 3 emissions account for 99.77% of our total emissions. This has slightly increased from 98.9% last year as our head office and company cars are leased and so are now allocated to our Scope 3 emissions.
As a result, the year-on-year comparison is summarised in the table below.

Our total emissions for the year come to 42,920 MTCO2-e, which compares to 37,721 MTCO2-e for the year to March 2021. A number of factors explain this increase and relate to the actions taken during the year to better account for and address our carbon footprint.
Our ongoing strategy to acquire renewable energy, shown in the breakdown of our leased locations emissions below, continues to significantly reduce our potential overall emissions. For this data period from 1 April 2020 to 31 March 2021, 82.4% of the electricity consumed by our portfolio was sourcing from renewable electricity. As we have highlighted already, this will increase to 94.6% as we now acquire just under 100% of our electricity from renewable sources.

Firstly, our total emissions for the current year include 6,777 MTC02-e of embodied carbon emissions, which were not included in our calculations in the financial year ended March 2021. As we go forward, we will look to reduce our levels of embodied carbon as part of our carbon reduction programme.
Secondly, the centralisation of our waste management has enabled better data collection which has enabled us to monitor that 42.3% of our waste was recycled and a further 54.4% was converted from waste to energy, with only the remaining 3.3% going to landfill. This has accounted for a reduction in our emissions as without the respective data, we had to assume that 100% of waste went to landfill.
Thirdly, the total number of business parks included in our emissions report increased from 65 to 69 during the period which together with a slight increase in heating use in the portfolio accounts for an increase of 4,490 MTC02-e during the year.
To highlight the work we have been doing on managing on our emissions, the table below provides an analysis of our core emissions on a per meter basis for the total portfolio estate for both years. As we continue to develop our pathway towards net-zero emissions it is clear that our approach will concentrate on the reduction of our heating emissions intensity.

Methodology
The reporting boundary was determined by Sirius. The organizational boundary covers the entire operations in Germany where Sirius has absolute financial & operational control. The reporting boundary also includes the Corporate Head Office and site offices of Sirius, its sister company SFG Nova & its leased locations.
The activity data was screened in the as-is condition for any inconsistencies or irregularities. The sources and sinks to be included in the inventory were then identified and verified as per The Greenhouse Gas Protocol – i)A Corporate Accounting and Reporting Standard; ii) Scope 2 Guidance; iii) Corporate Value Chain (Scope 3) Accounting and Reporting Standard.
Scope 1 - Stationary combustion
Scope 1 included the Stationary combustion of Berlin offices & offices occupied in every leased location of Sirius. Heating consumption emissions of these locations accounted in Scope 1 category. The emission factors are suppliers specific.
Scope 2 – Purchased Electricity
The emissions from the purchased Electricity and Cooling consumption of the offices occupied in every leased location of Sirius were accounted in Scope 2 inventory. The emission factors are used from Defra 2021.
Scope 3 – Category 1 - Purchased Goods & Services
Emission from water consumption & construction works were accounted in this inventory. For water consumption the emission factor is from Defra 2021 & the emission factor of the embodied carbon is supplier specific.
Scope 3 – Category 5 Waste Generated in Operations
The Emission from waste disposal & wastewater generated were accounted in this category. The Emission factors were specific to disposal type used from Defra 2021.
Scope 3 – Category 6 Business Travel
The emission from car, train, air & hotel stay were accounted in this category. Emission factors for all this travel is supplier specific.
Scope 3 – Category 8 Upstream Leased Assets
The purchased electricity of Berlin Head Office, electricity, heating, cooling of Sirius facilities GMBH & AXA JV Sirius Facilities GmbH were accounted in this category. Supplier Specific & Defra factors were used wherever applicable.
Scope 3 – Category 13 Downstream Leased Assets
The heating, electricity & cooling for all 69 leased sites were accounted in this category

BizSpace
We are in the process of integrating BizSpace’s environmental programme which remains at the early stages. As part of the integration, we have commenced a detailed assessment of the EPC ratings for the property portfolio. We are currently undertaking a review of the EPC data held by BizSpace to identify any gaps in the energy data requirements to build an accurate baseline on the current ratings. To date we have completed an EPC review on 20% of the BizSpace portfolio. We will then be in position to start to build a detailed model that will show any potential improvements to be made to each building. Once this process is completed, we can commence the implementation phase of a programme of improvements to achieve a higher rating in line with the UK Government’s proposed plans for all commercial rental property to have an EPC rating of “C” by 2027 and “B” by 2030.
As we have mentioned previously, we will also be including the BizSpace portfolio in our future net zero pathway for the Group and we are treating the EPC review as part of the decarbonisation programme to look at emission reduction opportunities. A first step towards this is understanding BizSpace’s GHG emissions and how they compare to those in Germany. This analysis is ongoing and continue during the current financial year. However, based on an initial assessment of the last four months of the financial year, which is the best representative period following the acquisition, we have outlined a summary of BizSpace’s GHG emissions below.

BizSpace utilises 100% renewable electricity from the grid and for the basis of this calculation we have assumed a markets based approach, so there are no emissions from purchased electricity to be accounted in the Scope 2 category. We do highlight that this assumption may change in the future as we continue the integration process. BizSpace’s total GHG emissions are calculated as 1106 MTCO2-e. As the table shows, the majority of the GHG emissions are classified as Scope 3 from the operational use of BizSpace’s properties by tenants across the 72 sites, representing over 97% of our total emissions. In the chart below, we have broken down the emissions at the leased properties, which are directly attributed to the operational use of our assets.
Leased Locations – GHG emissions breakup (MTCO2-e)
Methodology and emissions factors
The data used for the basis of calculations of emissions for the leased assets is for energy consumption from 1 December 2021 to 31 March 2022.
The area occupied by BizSpace’s space offices for each site has been assumed to be 350 sq ft in order to compute the heating emission for Scope 1 Inventory & Electricity Emission for Scope 2 Inventory.
Scope 3 Emission were calculated based on Water consumption, Waste disposal, Business travel & Downstream leased assets.
We will also, in the future, integrate BizSpace’s activities into our embodied carbon initiatives as well as our biodiversity programme.
