WASTEWATER & WASTE
Greenhouse gas (GHG) emission management is included in our overall environmental management
process. Results per production site are consolidated into tons of carbon dioxide equivalent (tCO2e) in both
absolute amounts and in terms of intensity (emission per unit of production). Monthly data is gathered
centrally from our production sites and forms the basis for monitoring against, and if necessary corrective
actions for, the annual targets. Conversion and emission factors used for the report were in consultation
with the Greenhouse Gas Protocol developed by World Resources Institute (WRI) and the World Business
Council for Sustainable Development (WBCSD). As the GHG emissions are directly related to energy
consumption, operative targets are expressed in energy intensity (GJ/t produced). Further details can be
found in this report under “Resource Efficiency”.
Water being discharged into open watercourses is an important topic regarding environmental pollution.
It is a basic requirement that manufacturing industry should discharge the water back into the ecosystem
without additional pollution load. How efficiently we manage and treat our effluent is of concern to all
stakeholders, especially regarding hazardous waste – and as such this is a reported under a separate
topic “Waste”. Any significant spills would also be reported under this topic. We also have an opportunity
to report on the positive influence of our technology systems on downstream customer’s wastewater
discharge.
For this reporting period we have not considered non-production sites (offices, off-site warehousing etc.).
We will be initiating measure to include these metrics in future reports, but our expectation is that the
overall impact on our total emissions will be relatively low.
Scope 1 and scope 2 GHG emissions for FY2018 amounted to 99 576 tCO2e. This represents a 2.9% increase
compared to FY2017 (96 798 tCO2e). Of the total for FY2018, 4 198 tCO2e are attributed to the additional
plants that came into the Archroma site portfolio due to the M. Dohmen acquisition. If these emissions
are excluded, for direct comparative reasons, our absolute emissions would have decreased by 1.5%
in comparison to the previous reporting period. The data for the Maracay site, Venezuela, has not been
included in both the current and previous reporting period to allow direct comparison.
All production plants have, or access to, wastewater treatment facilities that use physical and biochemical
treatment processes. All discharged treated wastewater are in compliance with the relevant standard
limits and mass loading requirements as stipulated by local environmental authorities.
Archroma discharged a total of 6.74 million m3 of water, 66% of this discharged to surface water after
suitable treatment to ensure conformity to the local requirements. The remainder is discharged to third
party effluent treatment sites for further processing before being discharged to surface water. The total
discharge represents 76% of total water withdrawn for operations.

Scope 2 emissions amount to 48 291 tCO2e, representing 48.5% of the total scope 1 & 2 emissions.
Of this 38 312 tCO2e (79%) is derived from purchased electricity, the remainder 9 978 tCO2e from purchased
steam.
75 %
Scope 1 emissions amount to 51 285 tCO2e, representing 51.5% of the total scope 1 & scope 2 emissions.
Of this 47 327 (92%) is derived from the combustion of natural gas, the remainder consisting of diesel and
heating oil. None of the Archroma sites use coal as a fuel for on-site generation of energy.

Our target will be carbon neutrality for scope 1 and scope 2 emissions in 2023, deriving annual targets
to reduce intensity levels, with the objective to off-set the remaining absolute GHG emissions.
Scope 3 emissions have not been calculated or estimated for Archroma for the reporting period, due to
the complexity of raw material supply distributed between global and local vendors to the sites and the
distribution to the industries which we serve. This will be an area of focus for the future and our target is
to establish a baseline for the FY2020 reporting period. After this has been done, targets will be established
to positively impact the results.

For the required fossil fuel based emission factors, we have used the 2018 Defra Greenhouse Gas Emission
Factors, developed by the UK Department for Business, Energy & Industrial Strategy and the UK Department
for Environment, Food and Rural Affairs. Electricity emissions factors have been determined from the data
supplied by the respective energy provider.
