^{Scope 1 and 2 emissions FY17 – FY19 (tCO2e) ¹ ²} 

1 Scope 1 includes direct emissions from operations we own or control. Scope 2 includes indirect emissions from the generation of purchased electricity, heating, cooling and steam that we consume or use.
2  FY18 Scope 2 emissions were recalculated and restated as a result of increased activity data accuracy used as the basis of estimated data. This resulted in a 332 tCO2e (10%) increase to the values previously reported in the FY18 Sustainability Report (3,328 tCO2e). The impact of the recalculation on the FY17 and earlier figures was deemed to be immaterial and did not warrant a prior period adjustment.

^{Science-based targets Scope 1 and 2 trajectory ¹}

1 ERM has set a science-based target against 100% of Scope 1 and 2 emissions. The FY14 base year and FY25 target are shown in the graph. ERM is on track to meet this target, with the performance following the science-based target reduction path. 

^{GHG emissions intensity Scope 1 and 2 FY17 – FY19 (tCO2e/FTE)¹} 

1 Scope 1 and 2 emissions normalized by average full-time equivalent (FTE) employees. 

^{Scope 3 emissions FY18 – FY19 (tCO2e) ¹ ² ³}

1 Scope 3 emissions include our indirect emissions from business travel, employee commuting and shared space electricity.
2 FY18 base year was recalculated to reflect new activity data for employee commuting, a new methodology and more specific emission factors (see references). Our reduction target from FY18 to FY25 remains the same.
3 Scope 3 emissions in North America increased due to a large project resulting in a 7% increase in North America business travel.

^{Science-based targets Scope 3 trajectory ¹}

1 ERM has set a science-based target for business travel and employee commuting, covering 73% of the total Scope 3 inventory. 

^{GHG emissions intensity Scope 3 FY18 – FY19 (tCO2e/FTE) ¹}

1 Scope 3 emissions from business travel and employee commuting normalized by average full-time equivalent (FTE) employees.

^{Global office energy use FY17 – FY19 (MWh) ¹ ² ³}

1 Office electricity consumption is restated by 501 MWh (3% of total energy use) in FY18, due to more precise measurement of our office electricity and new activity data.
2 Renewable Energy Certificate (REC), i.e. the tradeable part of generated electricity from renewable resources representing attributes such as GHG emissions.
3 Shared electricity is the portion of shared resources for which ERM is responsible in multiple-occupant buildings. This category does not fall under ERM’s science-based targets.

Data presented here supports the Climate change section of this report. All data has been calculated using a market-based approach, unless otherwise stated.The emissions data presented includes data from the BrownFlynn acquisition. Emissions data normalized by average full-time equivalent (FTE) employees to reflect this in the intensity graphs. All 2019 ERM acquisitions are included in the Health and Safety data starting the date of the acquisition. Our People data includes the complete data sets from BrownFlynn and MP&A.

All emission data presented is expressed as carbon dioxide equivalent (CO2e) and includes all Kyoto gases and refrigerants. ERM uses the Fifth Assessment Report as a source of Global warming potential (GWP) without Climate feedback. The detailed reference table can be found below.
