Data sources, quality and allocation Crown Paints primary data was used for all internal processes. The products included in the product group presented in this EPD are 903, 905, 906, Brilliant White, and Magnolia shades packaged in 2.5, 5, and 10 litre containers. The different products were combined using production volumes to obtain a weighted average of impacts for all shades and pack sizes.

Data provided directly by Crown were collated under EN15084 guidelines to ensure cut-off criteria and other LCA requirements were met. Data were sense-checked against published data for similar products and other secondary sources. Data questions arising during the analysis were satisfactorily answered by technical experts at Crown.
Site wide, 2020 data were received for manufacturing and physically allocated, on a per litre basis, to the paint produced during the period.
Secondary characterisation and resource use factors were obtained from the Ecoinvent 3.7.1 database for life cycle modelling up and down the supply chain. Additional data used were as follows: ● Data from published EPD to estimate amounts of plastic sheeting used during paint application; ● Data from Plastics Europe to determine the impacts from polypropylene primary packaging; ● End of life reuse and disposal stream rates are listed on the basis of Crown knowledge and recent data from reliable sources; ● Substrate disposal reuse and disposal streams are made on the basis of UK construction industry recycling statistics from Defra´s UK Statistics on Waste (2015) Table 3.1: Recovery rate from non- hazardous Construction and demolition waste 2010-2012, and end-of-life scenarios from the PEFCR for Decorative Paints.
Overall, data received were technologically, temporally and geographically representative and of good quality.
Cut-off criteria
Cut off criteria are: 1% of the renewable and non-renewable energy usage 1% of the mass of the process under consideration. The total neglected flows shall be no more than: 5% of the energy usage 5% of the total mass.
Biogenic Carbon
The mass of biogenic carbon containing material in the product is less than 5% of the mass of the product and is omitted from this declaration.
The mass of biogenic carbon containing material in the packaging is less than 5% of the total mass of the packaging and is omitted from this declaration.
