The organisation-specific metric chosen to calculate the ratio was metric tonnes (t) of production. All types of energy are included within the intensity ratio: fuel, electricity, heating, cooling, and steam. The ratio used energy consumption within the organisation.
The data has been calculated to three significant figures. The base year for our calculation is 2018, as it is considered the most recent representative year for production across Infineum sites globally. The calculations account for the six major GHGs (CO2, CH4, N2O, HFCs, PFCs, and SF6) where possible.
Non-renewable electricity and steam at our site in Vado Ligure, Italy is produced by natural gas being burned in the co-generation unit and the energy use is accounted for as Natural Gas.
We use Department for Environment, Food & Rural Affairs (DEFRA) emission factors for most emissions except for refinery fuel gas where we use the molecular content of gas and stoichiometry; and grid electricity for the UK and USA, where we use the International Energy Agency (IEA) and Environmental Protection Agency (EPA) factors instead.
When refrigerant data is unavailable, we use estimates based on average leak rates supplied by DEFRA UK.
We measure GHG emissions based on the operational control criterion and follow the GHG Protocol Corporate Standard for scope 1, 2 and 3 emissions. We are measuring the following scope 3 emission categories: purchased goods and services, capital goods, fuel and energy related activities, upstream transport and distribution, waste generated in operations, business travel, employee commuting, upstream leased assets, downstream transport and distribution, processing of sold products, use of sold products, end of life treatment of sold products and investments.
We work with site leads to identify the most suitable individual(s) to identify the direct and indirect emission sources for that site and provide emissions and other environmental data each month. We engage with these representatives on a monthly basis.
Small offices (10 or fewer Infineum colleagues) are excluded from emissions estimates.
Due to the Services Utilities Materials Facilities (SUMF) agreement for our Rio de Janeiro site, estimated consumption of steam and electricity figures are yet to be independently metered. As a result, this site is billed for steam consumption in the amount of natural gas used to generate said steam.
Previously reported figures have been recalculated to correct errors and reflect more accurate and up-to-date emission factor data.
