ENERGY AND GREENHOUSE GAS REPORT
ANNUAL ENERGY USE AND EMISSIONS
As part of the Streamlined Energy and Carbon Reporting
(SECR) requirement, RWS is required to report its energy
and Greenhouse Gas (GHG) emissions within its Directors’
Report. The Group’s GHG emissions were prepared in
accordance with the UK Government’s SECR guidance.
The analysis conforms with the GHG Protocol Corporate
Standard (2004) and relates to the emissions of all
locations within the Group.
Our annual global energy use (in MWh) and associated
greenhouse gas emissions (tCO 2e) have been summarised
in the table. As mentioned previously, we have expanded
and enhanced our carbon emissions data collection
methodology which has resulted in a significant increase
in our reported Scope 3 emissions when compared with
the previous year. These now account for circa 90% of our
overall carbon footprint and will be used to develop our
carbon reduction strategy going forward.
The overall data quality was "considered good and
comprehensive, with common and statistically
insignificant data quality issues".
The results of the analysis will be used to provide us with
transparency on our emissions, enable us to setup and
implement specific carbon reduction measures and the
foundation to track our progress in reducing carbon
emissions, as well as to evaluate the effectiveness of our
reduction measures. In FY22, RWS offset all non-avoidable
emissions with high-quality carbon offsetting projects.
Overall results* (FY22)
Scope 1
473.41 tCO 2e
Scope 2
4,415.63 tCO 2e
Scope 3
47,736.02 tCO 2e
Total
52,625.06 tCO 2e
* location-based: although we have reported on location-based carbon
emissions, these were also calculated from a market-based perspective. Scope
1 and Scope 3 remained the same however, Scope 2 reduced to 4,232.18 tCO 2 e
from a market-based perspective
Explanation: A location-based method reflects the average emissions intensity of
grids on which energy consumption occurs (using mostly grid-averaged emission
factor data). A market-based method reflects emissions from electricity that
companies have purposely chosen.

*** Our Scope 3 emissions methodology was enhanced in FY22 and we were
able to report on more Scope 3 categories than in previous years. This fully
supports our commitment to set science-based targets. Scope 3 emissions
previously covered two categories including waste and business travel. This
has now been expanded to seven categories which includes purchased goods
and services, capital goods, fuel and energy related activities, waste generated
in operations, business travel, employee commuting and home office, and
upstream leased assets.
UK data covers office locations in Alnwick, Bloxham,
Chalfont St Peter, London (Great Tower Street and
Tavistock Square), Maidenhead, Nottingham and
Sheffield. The UK share makes up 9% of the total energy
consumption.
