TECHNICAL
The 80/20 approach to data collection on significant emissions is used to prioritise effort and resources on the most significant sources of emissions within a company’s inventory. It’s based on the observation that, in many cases, approximately 80% of effects come from 20% of the causes. How the process works For companies making their first carbon assessment, the process is based on a collective approach, consisting of four separate sessions of three hours each, plus individual support. We have chosen a powerful cloud- based tool which converts physical flow into CO 2 equivalent, relying on public databases and taking into consideration the country of origin where activities take place. Information remains confidential. Over the course of just four months, all members have carried out a first carbon assessment for their Organisation. The approach brings several huge benefits: n Accurate figures can be shared with reporting bodies, peers, and value chain partners n Commercial data remains confidential Examples of usable public data and sources n Energy and fuel bills n Employee travel information (especially air travel, e.g.travel agency or expense reports) n Travel information (e.g., mobility survey) n Information on the transport of goods (if goods)
of mature members as well as members at various stages of carbon assessment expertise. The group is supported by external experts and specialised tools. The pilot intends to validate: n whether the FTTH Council could help organisations to build their scope 1,2,3 n whether a consensus on a sector data format could be found so that organisations would agree to share n whether this would allow to build a sector database n whether a carbon sector model could be built on top For a sector organisation such as the FTTH Council, this would make it possible to: n communicate on the decarbonisation of the fibre sector n onboard more companies to make their carbon assessment and identify their main levers n create synergies and dynamics around GHG emission mitigation in the FTTH sector n estimate the carbon footprint of the organisation itself n emulate and follow the sector progress n offer the biggest European group of sustainability experts dedicated to the fibre sector n allow peers to share practices, ideas and create sustainability synergies n support and accelerate the European green deal through a sector initiative Members can obtain an initial estimate of the main emission categories prior to their first formal carbon assessment. They also have access to complementary data that helps them achieve a fast, realistic carbon assessment or contribute to complete an existing assessment. The collective approach with peers also means all members can develop and optimise methodologies and learn faster. For an initial estimate, transparency and honesty are key. All assumptions for data collection and choice of emission factor should be recorded. Including information on how data was obtained and consolidated is valuable for updating. What is particularly important is to set an accuracy level for each data, leading to a global accuracy level.

The conversion methodology
All of a company’s activity flows are translated into physical metrics. This data is not always readily available. Automating collection of this data can be challenging. The frame of the study introduces another challenge. Companies can deliver to other markets in addition to FTTH and other geographies besides Europe. Production sites are usually organised by means rather than by market. Therefore, distribution key needs to be discussed and agreed internally. Once available, such data is converted into CO 2 equivalent through proven conversion factors. Depending on the company’s activity, a list of relevant data covering all its GHG emissions is defined. And each activity data is then converted to kgCO 2 e using emission factors drawn from public databases (e.g. ADEME carbon base in France or DEFRA database in UK). The result is eventually expressed in CO 2 e (CO 2 equivalent), categorised per scope, emission categories and different greenhouse gases.
