Appendix: Operational footprint data

Restatement of CO₂ emissions data

In 2020, we performed a review of our reporting scope and calculation as follows:

The sale of ReAssure in 2020 resulted in the removal of three offices in the UK from our reporting scope. As they were a significant source of emissions in the EMEA region, this led to a large reduction in the Group’s overall emissions.
After further analysis of green energy assurances for grid power in the UK, we have changed the calculation method for our offices in this region to using market-based factors for electricity emissions. This caused a sharp drop of 46% in overall emissions per employee (kg/FTE) for power.
An update to our technical gas calculations now allows us to more accurately track leakages from large tanks and generators, rather than only “charging“ emissions at the point of refill. This led to a significant increase in the emissions tracked for technical gases.

Our three ReAssure offices in the UK were responsible for a substantial part of our CO₂ footprint. In connection with the sale of ReAssure in 2020, we made two significant changes to our emissions reporting scope and calculation. Firstly, we removed the three offices, which included a large data centre, from the scope. Secondly, we switched from conventional to market-based factors because we use renewable energy at our offices in London and Folkestone.
Beyond accounting for the removal of our ReAssure offices in the UK, we made corrections concerning locations where we have clarified that we do not consume heating fuels.
The ReAssure offices were paper-intensive due to the nature of their consumer-facing insurance business.
As the ReAssure offices had a zero-waste policy and low water consumption, their removal from our reporting scope led to an increase of the Group’s average figures in these categories.
We now include a 5% estimate for losses on all technical gas stores, whereas only actual refills were previously reported.
The employees who commuted to our ReAssure offices had higher-than-average usage rates of CO₂-intensive car travel.
Totals are actuals before rounding, rather than the apparent sum of integers.

The unit “tonnes“ represents metric tons.
“Scope 1“ includes operational road travel, heating oil/gas, technical gas.
“Technical gas“ is reported as Scope 1 as Swiss Re has direct control over the majority of its fugitive emissions. Also included is a smaller amount with indirect control.
“Scope 2 emissions (market-based)“ UK data series corrected in 2020 to include renewable CO₂ factors (previously assumed UK government kept green credentials).
“Renewable electricity“ figures include green electricity, self-produced (solar) as well as locally-sourced renewable energy certificates.
“Commuting“ figures obtained by means of biannual survey have considerable measurement uncertainty.
“Other Scope 3“ includes energy transmission, technical gas, paper, waste and water.
“Business travel“ figures include air travel, rental cars and rail, and exclude operational shuttle bus.
“Carbon certificate offset“ covers total absolute CO₂ emissions (less commuting).
Dataset rebaselined in 2020 to remove ReAssure after its sale.
Reporting year is on a hydrological calendar year basis (ie 1 October 2019 until 30 September 2020).
