Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. This is an immobile infrastructure representing the drilling of an offshore well for oil or/and gas exploration extraction. The infrastructure represents all the types of offshore drilling. The rotary drilling method is predominantly used in wells for finding and producing oil/natural gas. The offshore drilling activity requires space for both supply and disposal. A temporary area of about 0.2 ha is required for the storage of the roughing cement and other supplies (chemicals fuels) for a well of about 3 400 m depth. The drilling time is about 2 months. The stress on the benthos (animal and plant life of the seabed) as a disposal site is assumed for the duration of one year. Thus per meter drilled about 260 m2 of seabed is severely impacted. The process includes all energy uses materials and emissions for drilling of an offshore bore hole and finishing of the well. No differences depending on depth of sea and type of geological formation are taken into account. The cut-off classification is allocatable product. The activity type is market activity. The reference product amount is 1.

Emission intensity of supply chain in GBP spend on: buildings and building construction works. Provided by BEIS/DEFRA in the official report on UK and England's carbon footprint to 2019. Retrieved from the UK full dataset 1990 - 2021 including conversion factors by SIC code (sheets: ghg_sic_mult and co2_sic_mult).

Emission intensity of supply chain (with margins i.e. cradle to shelf) in US dollars spend on: commercial and institutional building construction. This factor is representative of the described goods or services category as defined by the 2017 version of the North American Industry Classification System (NAICS). Refer to the source for the source-specific data quality assessment. Retrieved from Supply Chain Factors Dataset v1.2.

Commercial and institutional building construction

Emission intensity of supply chain (with margins i.e. cradle to shelf) in US dollars spend on: commercial and institutional building construction. This factor is representative of the described goods or services category as defined by the 2017 version of the North American Industry Classification System (NAICS).

Emission intensity of supply chain in EUR spend on: construction work. Retrieved from the EXIOBASE v3.8.2 model outputs for products. These factors were calculated based on 2019 data. They include emissions from land-use. The split into constituent gases is not provided as the source does not provide a split of gases. The LCA boundaries of these factors are not defined by the source. These factors include effects of international trade.
