What are scope 1 emissions?

Scope 1 emissions refer to direct greenhouse gas (GHG) emissions from sources that are owned or controlled by a company. These emissions include those from combustion of fossil fuels, such as coal, natural gas, and oil, used for heating, transportation, and other activities.


Measuring and reporting on scope 1 emissions is important for companies as it allows them to understand their direct GHG emissions and identify areas for improvement. It also enables companies to set and track emissions reduction targets and take action to reduce their environmental impact. This is particularly important as governments and investors are placing more emphasis on companies to reduce their GHG emissions in order to mitigate the impacts of climate change.


There are several methods for measuring and reporting scope 1 emissions, including the use of emissions factors and direct measurement. Emissions factors are estimates of the emissions per unit of activity, such as emissions per unit of fuel consumed. Direct measurement involves measuring the emissions directly from the source, such as using a CEMS (Continuous Emissions Monitoring System) to measure emissions from a boiler. These methods are commonly used in combination, to ensure accurate and comprehensive measurement.


Additionally, companies can also opt for using a life-cycle assessment (LCA) approach to measure their scope 1 emissions. LCA is a methodology that takes into account the entire life-cycle of a product or service, from raw material extraction to disposal or recycling. This enables companies to identify and account for emissions from all sources in their value chain, including those that are not controlled by the company.


In conclusion, scope 1 emissions refer to direct GHG emissions from sources that are owned or controlled by a company. Measuring and reporting on scope 1 emissions is important for companies as it allows them to understand their direct GHG emissions, identify areas for improvement, and set and track emissions reduction targets. By using a combination of emissions factors, direct measurement, and LCA, companies can ensure accurate and comprehensive measurement of their scope 1 emissions and take action to reduce their environmental impact. This is particularly important as governments and investors are placing more emphasis on companies to reduce their GHG emissions in order to mitigate the impacts of climate change.
