Carbon Footprint Analysis
Reporting of Greenhouse Gases

ECI works directly with our clients to determine what items to include in the facility carbon footprint analysis. ECI understands that there is no one method used worldwide to develop/calculate a facility carbon footprint.  A carbon footprint analysis may include the basics such as fuel usage (i.e., natural gas, fuel oil, bio-fuels, etc.), transportation or forklift use. Other carbon footprint analysis may include additional items such as electricity and water usage, wastewater discharged, or raw materials used/consumed in a process.

There are a number of methods used to calculate a facility’s carbon footprint/greenhouse gas emissions. ECI has provided clients with Mandatory Reporting of Greenhouse Gases under 40 CFR Part 98 and has developed mathematical models to calculate Greenhouse Gas emissions from very complex industrial facilities using the guidance and mathematical models set forth in 40 CFR Part 98.

The methodology described herein incorporates the international guidelines provided by the Greenhouse Gas (GHG) Protocols (i.e., Scopes 1 through 3) which incorporates carbon dioxide (CO2) equivalents: CO2, methane (CH4) & nitrous oxides (N2O) emissions from various sources or operations at a facility. It should be noted that the following GHG Protocols include the guidance and mathematical models set forth in 40 CFR Part 98, but are more inclusive.

Using the GHG protocol whereby “Scopes” are defined, the items and Scopes incorporated into the calculations for a facility’s carbon footprint (i.e., under normal operating procedures) are as follows:

Scope 1:

  • Boiler & other energy fuels (Natural Gas, fuel oil, propane, bio-fuels, etc.);

  • Transportation of materials [(assumes the vehicles are owned, if not it is Scope 3) diesel, gasoline, etc.]; and

  • Forklift use.

Scope 2:

  • Electricity purchased; and

  • Water used/purchased.

Scope 3:

  • Wastewater discharge;

  • Chemicals/raw materials used and transportation of the chemicals/raw materials;

  • Employee transportation (to and from work);

  • Transportation of finished goods/products, leased vehicles; and

  • Purchased items (not included above).

Where possible ECI incorporates carbon footprint factors based on data received from the United States Environmental Protection Agency (EPA) and the United States Department of Energy (DOE) to directly calculate carbon footprint factors or to indirectly verify data obtained from other sources. In addition, ECI will develop and implement survey(s) to obtain necessary regional (i.e., facility specific) information to establish a carbon footprint factor for a specific item.

ECI has provided greenhouse gas emissions calculations for numerous private companies, municipal and government clients throughout the United States and the world. ECI has conducted surveys for greenhouse gas emissions from potable water supply (i.e., drinking water) and wastewater treatment facilities throughout the United States and has shared these results with the EPA. ECI’s survey results may impact the emission factors used by the EPA and DOE regarding their carbon footprint calculations for these utilities in the future.

ECI in communications with our clients develop a spreadsheet questionnaire with detailed instructions requesting specific information from an operational facility(s).  Each facility is requested to fill in the data requested on a spreadsheet questionnaire and forward the spreadsheet data to ECI.  Follow-up contact/questions are normally sent out to the operational facility(s) based on the specific spreadsheet data supplied to ECI.

ECI will develop a facility specific carbon footprint factor for each item (i.e., electricity, chemicals, raw materials, water, etc.) and incorporate these site-specific factors into the calculations for the facility’s carbon footprint. This methodology ensures that the calculated carbon footprint is as accurate and will withstand audit review/scrutiny in the future.

ECI personnel are familiar with virtually all “smoke stack” and chemical processes used today and the appropriate methods used to calculate facility specific carbon footprints and other emissions from these stationary sources. This familiarity allows ECI personnel to be accurate and fast saving time and money for our clients. ECI personnel have provided support nationwide and internationally for manufacturing processes related to cement, iron and steel, lime, pulp and paper, aluminum, copper, lead, zinc, steam and power generation, pharmaceutical, petrochemical, chemical, and petroleum products; and for the treatment of industrial, hazardous, municipal, radioactive, mixed, pathological, and medical waste. ECI personnel are expert in combustion, thermal treatment, destruction removal efficiency, and air pollution control (APC) technology with expertise in virtually all types of treatment, including thermal oxidation, thermal desorption, thermal/catalytic destruction, and vitrification. ECI personnel have led the development of combustion equilibrium analysis computer software, including a model to size off-gas and APC equipment; participated in EPA’s Superfund Innovative Technology Evaluation program; supported the development of cogeneration and waste to energy facilities; supported the privatization and transfer/sale of large groups of power plants; provided specifications for mobile & stationary source combustion software.

ECI personnel are familiar with all types of mobile source carbon footprint emissions. ECI developed an emissions reduction and control strategy for three cities in Northern China. The 300 page document was the result of a 2-year study that provided strategies for reducing vehicle (i.e., carbon footprint) emissions. ECI was involved with vehicle emissions testing and ambient air testing for greenhouse gases and other emissions during this project. The final report contained proposed regulations and standards for inspections, certification/registration, testing, and operations of motor vehicles; alternate energy/fuel sources for motor vehicles; road and traffic designs to reduce air emissions; and an overall guideline to reduce air emissions from private and fleet motor vehicles.

In addition, ECI developed the extensive environmental work plan for the private bridge to link Buffalo, New York with Fort Erie, Ontario. One of the major concerns for the environment is the mobile source emissions (i.e., carbon footprint and other emissions) from vehicle traffic and traffic patterns. ECI developed the work plan using both the United States and Canadian regulations and guidance for this very extensive and internationally recognized project.
