Office Energy Consumption
We continue to realize opportunity to reduce energy usage in our 160 offices . We have prioritized reductions in square footage per person in our offices , leading to a year over year net reduction of 104,000 sq ft . Total office energy use was reduced by 9.6 % over FY22 . Electricity use rose by 1,247 MWh , however , natural gas use fell sharply by 9,828 GJ . When normalized to full-time employees ( FTEs ), we reduced our electricity usage by 7.9 % and our natural gas usage by 46.4 % in FY22 .
Operational efficiencies , including office closures ; relocations and consolidations ; lighting upgrades ; adoption of more flexible work from anywhere practices ; and promoting awareness and behavioral changes have contributed to this reduction . We have prioritized reductions in square footage per person in our offices , leading to a net reduction of ~ 104K sq ft in FY22 , despite adding approximately 135K sq . ft . from acquisitions .
We currently lease five LEED certified buildings and have developed Green Lease specifications to assess efficient building space for all new leases .

Greenhouse Gas Emissions by Scope
Our efforts to increase energy efficiency and fuel economy translate to reduced greenhouse gas emissions when normalized to headcount .
SCOPE 1 & 2 EMISSIONS
11.4 % of 2030 target achieved since 2019
Scope 1 emissions include fuel use in all TRC fleet vehicles as well as natural gas use for office heating . Breaking down our Scope 1 emissions , fleet emissions are approximately 7.5 times greater than emissions from office natural gas use .
In line with business growth , the composition of our fleet has evolved with an increased number of trucks for field work . From FY14-FY22 , our class C-H fleet has grown from approximately 300 vehicles with 2.9 million annual miles to around 850 vehicles with 11.4 million annual miles . Much of our field work requires larger vehicles to haul equipment and handle the wear and tear at job sites . Accordingly , our overall fleet emissions have increased on an absolute and normalized basis .
Emission reduction efforts have been impacted by ongoing limited availability of new , more efficient vehicles . As supply chain issues resolve , we expect to be able to retire more of our older less efficient vehicles .
