Reporting for Calendar Year (CY) 2021
ES3’s GHG emissions are broken down by scope and reported as follows:
Scope 1 GHG emissions represent the smallest contributor to ES3’s carbon footprint and come from process emissions, combustion of gasses on site (heating), and the combustion of gasses from ES3 owned and operated vehicles. Natural Gas is used as the main heating source for ES3 buildings. During CY20, ES3 enhanced the air distribution systems in our two manufacturing facilities by installing modern air ducting and filtration systems. The modern ducting evens the heat distribution across the facility, improving the efficiency of our heating systems which continues to reduce our on-site Scope 1 GHG emissions for our two production facilities. ES3 company vehicles are used for transportation to off-site work locations as well as pickup of supplies and delivery of work products. In 2020, ES3 purchased an electric vehicle and implemented more efficient logistical planning both of which provided us with Scope 1 GHG reductions in 2021. ES3’s GHG emissions from company owned vehicles are well below the estimated US average of 4.6 MT CO2E per vehicle.
Scope 2 emissions are ES3’s primary GHG contributor and consist primarily of purchased electricity used for lighting, equipment power, and air conditioning. Scope 2 emissions are highly variable from year to year and depend on factors such as company workload and weather conditions.
Scope 3 emissions for ES3 are primarily due to business travel and shipping. During the pandemic of 2020 and 2021, there was a decrease in business travel due to COVID-19 restrictions Much business travel was replaced with online video conference calling when possible.
ES3 will continue to maintain environmentally conscious work practices at all facilities located across the US. ES3 continues to maintain an Environmental Management System (EMS) certification (ISO 14001:2015). With this certification, ES3 tracks and monitors various environmental metrics, including energy use and air emissions. The data obtained from the EMS is used to help increase environmental awareness to employees, help ES3 understand its environmental impact, ensure ES3 is meeting all local, state, and federal regulations, and help ES3 set realistic and attainable goals for reduction of GHG emissions.
ES3 reports a total GHG emission of 1371.33 metric tons of CO2E for CY2021. With employees located at five facilities across four US states, that equates to 8.4 metric tons of CO2E per employee. That results in 7.5% reduction per employee compared to CY2020.
