GHG Inventory

INEOS has developed a science-based method for emissions accounting to gather GHG data for compliant scope 1 and scope 2 reporting according to the GHG Protocol. It tracks GHG performance across all INEOS sites based on robust performance metrics and to assess GHG reduction measures against quantified targets by 2030 and 2050.

INEOS respects the general principles on GHG reporting: relevance of information to internal and external audiences, consistency and transparency of methods, data sources and assumptions, comprehensiveness and accuracy of tables and figures, and traceability of progress; to the extent as reasonably possible.


Using the INEOS science base, the Group footprint is calculated per calendar year according to the GHG protocol. The financial control approach is used with INEOS AG as parent company, including all subsidiaries, joint ventures and joint operations, except for offices, sports and fashion activities. Petroineos and INEOS Infrastructure (Grangemouth) Ltd are included in the 2021 reporting boundary of INEOS AG, despite sitting to the side of INEOS AG in the organogram since they are classed as JVs in the consolidated financial accounts of INEOS Group Holdings SA.

The operational boundaries of the GHG inventory cover all process emissions, material emissions from stationary and mobile combustion, flaring and emissions from purchased energy.


GHG data are sourced from all INEOS sites within the scope defined above, using operational data, emission factors and recognised tools such as the GHG Protocol CHP tool. The quality of the GHG inventory is ensured with internal data consolidation with feedback loops.

a 2019 is defined as reference year for tracking INEOS' footprint over time; historical data is recalculated following the all-year/same-year approach taking into account the structural changes.
b Other GHG emissions are converted to CO2e using the 100-year Global Warming Potential (GWP) factors from IPCC's fifth assessment report; CH4 and N2O emissions are 3004 t and 136 t respectively in 2021, while other GHG data are collected only in t CO2e due to lower materiality.
c Emissions on energy exported to 3rd parties are reported as a separate subcategory of scope 1; all emissions in this category are in CO2 with negligible contribution of other GHGs (<0.01%).
d The scope 2 figure is based on gross energy purchase with negligible contribution of other GHGs (<0.01%); highest quality available emission factors are used as per the hierarchy in the GHG protocol.
e Total emissions are calculated using the market-based scope 2 figure; this figure is also reported in INEOS' sustainability report and is used as basis for INEOS' emission reduction strategy.
f Captured CO2 is mostly transferred outside our boundary and sold to 3rd parties; only 1% of the capture is mineralised onsite to produce carbonate.
