A Green House Gases (GHG) emission inventory or Carbon Footprint – is the quantity of CO2 and other GHGs (CH4, N2O, HFCs, PFCs & SF6) emitted from a facility (either directly or indirectly) on an annual basis. Larger companies such as Walmart and others are requiring their customers to complete a carbon footprint. EPA requires the reporting of direct GHG emissions from certain industrial facilities.
What IES will do
IES environmental engineers will visit your facility to complete the GHG inventory by taking natural gas and electrical usage data and calculating the corresponding GHG emissions according to the scope shown below:
- Scope 1 determines direct emissions from combustion sources (boilers) and refrigerant gas leaks. Company owned vehicles are also included in Scope 1 assessments.
- Scope 2 includes Scope 1 emissions above and indirect GHG emissions such as those associated with electrical use or importing process steam from other facilities.
- Scope 3 includes Scope 1 and 2 emissions and GHG emissions from sources such as product transport, raw materials, product usage and disposal, employee commuting and other activities (some companies do not require Scope 3 emissions to be included).
Information is typically reported in units of CO2 equivalents (CO2e). The report format will be structured so that data can be directly uploaded into the GHG registry – of choice (CDP, Climate Registry, etc)
What happens with the results?
Based on your calculated GHG levels, an IES specialist can also assist you in developing CO2 reduction goals and the corresponding action plans or projects that will help meet those goals
