ENERGY AND GREENHOUSE GAS REPORT
As part of the Streamlined Energy and Carbon Reporting
(SECR) requirement, RWS is required to report its energy
and GHG emissions within its Directors’ Report.
As mentioned previously, during FY22 we improved the
accuracy of our footprint by improving our data collection
and GHG emissions to include both our operations and
supply chain, and committed to setting carbon reduction
targets which are aligned with SBTi.
As part of the development of our science-based targets,
and as a result of switching to an enhanced software
platform, we decided to recalculate our FY22 footprint to
ensure consistency in measurement and methodology. This
resulted in a more accurate carbon footprint for FY22 which
is detailed below.
Some of the key changes include:
Scope 1:
• Updated footprint to include comprehensive
information on building fuel usage in the previous
footprint, and added months of fuel data missing
for certain o昀케ces
Scope 2:
• Watershed used more representative emissions
factors for district heat and supported with more
transparency in reporting
Scope 3:
• Purchased goods and services – enhanced reporting
Methodology
Emissions were calculated following the GHG Reporting
Protocol (Corporate Standard) using the Watershed
platform. Energy usage data was collected or estimated
based on building square-footage for all facilities, and
was combined with emissions factors from the US
Environmental Protection Agency (EPA), Ecoinvent,
Technical Compliance Rate (TCR) and other data sources
to calculate GHG emissions. Electricity emissions factors
are chosen based on geography to re昀氀ect the emissions
intensities of the facilities’ local grid.
GHG Scope
enabled us to split localisation agencies and
freelancers and use more appropriate emission
factors (agencies’ emission factor – 0.0840782073
kgCO2e / USD and now coded freelancers as
‘Independent artists, writers, and performers’ using
emission factor 0.0142133408 kgCO2e / USD)
•
Cloud emissions – Watershed’s usage of vendorspeci昀椀c emissions factors enabled more accurate
measurements
•
IT services and equipment – transparent
reporting enabled more accurate use of EEIO

A location-based method re昀氀ects the average emissions intensity of grids on which energy consumption occurs (using mostly gridaveraged emission factor data). A market-based method re昀氀ects emissions from electricity that companies have purposely chosen.
