Biogas Clause Samples

Biogas. The production and use of biogas is relatively new in Norway. Our time series starts in 2006 and until 2014 we collected consumption data from only a few units (included losses from flaring). This was mainly biogas used for land transport (▇▇▇▇ 49) and in sewerage management (▇▇▇▇ 37). We also had consumption data from a few units in manufacturing and from district heating plants. The production was imputed by summing up the intermediate consumption. In 2016, we sent out questionnaire to potential producers and suppliers of biogas. This was successful, and we will send out an annual survey from now on. From the year 2015, we have data on production and losses by 5-digit ▇▇▇▇, and we have sales data to ▇▇▇▇ aggregates. In some cases, these sales data are more aggregated that the requirements in PEFA. We then use break-down keys and simple assumptions to allocate the data. For example; sales to ▇▇▇▇ division 77-82 are grouped together. We place this sale as consumption under “N80-N82 Security and investigation, service and landscape, office administrative and support activities” in full. Intermediate consumption in manufacturing and energy producing industries are excluded from the biogas questionnaire. This data is instead collected by our annual business surveys. We also use some additional data from the Norwegian Environment Agency to make sure that we cover all the consumption (by type of use; for transformation and own use) in “E37-E39 Sewerage, waste management, remediation activities”.
