We strive to reduce carbon emissions from our operations and provide customers with resilient, low-carbon solutions.
Construction is a carbon-intensive industry that typically involves the extraction, manufacture and transport of large quantities of materials, as well as construction activities. The way we design and construct buildings and infrastructure projects can have a significant effect on the amount of emitted greenhouse gases. Skanska measures carbon footprints on both project and Group level and work on how to reduce our emissions.
Greenhouse gas reporting
Skanska's greenhouse gas reporting covers all Business Units. We measure carbon emissions in accordance with the Greenhouse Gas Protocol. Activity data is based on invoiced data, real-time meters, models and estimates or data as reported by suppliers.
Energy conversions are done using publically available conversion factors and emission factors are sourced from open databases like International Energy Agency (IEA) and Reliable Disclosure Systems for Europe (RE-DISS).
Greenhouse gases included in the reported carbon inventory are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Skanska applies the financial control approach. Emissions data is subject to inherent uncertainties due to incomplete scientific knowledge used to determine emission factors and resulting effects on measurements and estimations.
A limited assurance engagement of the Skanska carbon emission inventory is undertaken by Skanska's auditors.
Carbon emission categories
Scope 1 emissions include direct emissions that occur from sources owned or controlled by Skanska, such as boilers, furnaces and vehicles. Scope 2 includes indirect emissions from the generation of electricity, heating and cooling purchased and consumed by Skanska. Scope 2 emissions physically occur at the facility where the electricity, heat and cooling is generated.
In 2017, Skanska achieved Leadership level (A-) in the CDP (Carbon Disclosure Project) climate change, water and forest/timber rating. This indicates Skanska has implemented actions to manage environmental impacts related to climate change, water, and forest and timber.
