Greenhouse Gas Emissions

Reporting for Calendar Year 2019

The Greenhouse Gas (GHG) Protocol categorizes a company’s GHG emissions as one of three “Scopes”. Scope 1 is classified as direct emissions from owned or controlled sources (i.e. mobile combustion, stationary combustion, process emissions). Scope 2 emissions are classified as indirect emissions (i.e. purchased energy). Scope 3 emissions are all remaining indirect emissions not included in Scope 2 (i.e. business travel, distribution, shipping and logistics).

GHG emissions are commonly reported in metric tons of carbon dioxide equivalent (CO2e). CO2e is a way to quantify and combine various greenhouse gasses, such as CO2, NH4, and N2O, into a singular unit. ES3’s GHG emissions are broken down by scope and displayed as follows:

Scope 1 GHG emissions are the smallest contributor to ES3’s carbon footprint and come from ES3 owned and operated vehicles.

Scope 2 emissions—purchased energy for facilities, including our manufacturing, overhaul, and test facilities—make up the majority of ES3’s carbon footprint. In 2018, ES3 purchased and installed 400 high efficiency lighting fixtures at our 120,000 square foot Material Research & Development Center (MRDC). In 2019, ES3 installed modern, high efficiency Heating, Ventilation, and Air Conditioning (HVAC) units at the MRDC, our largest facility. Although ES3 is improving the efficiency of our energy usage, our Scope 2 energy usage is increasing because ES3 workload is increasing.

ES3’s Scope 3 emissions are primarily due to travel and shipping. ES3 was able to reduce our business travel from previous years, however, shipments of the heavy components we manufacture and overhaul are increasing as our workload is increasing.

Goals for 2020

ES3 sets a GHG emission reduction goal of 5% for 2020 adjusted by revenue. Our approach for meeting this goal includes:

Reduction Goals for Scope 1 Emissions:

    • Maintain vehicles to operate at maximum efficiency
    • Replace ES3 fleet vehicles with electric or hybrid vehicles when possible.


Reduction Goals for Scope 2 Emissions:

    • Replace old windows with energy efficient windows
    • Install high efficiency water heaters
    • Expand usage of timers/motion detectors for lighting


Reduction Goals for Scope 3 Emissions:

    • Replace business travel with video conferencing if possible.
    • Be mindful of shipping practices and workout efficient shipping logistics when sending multiple products to customers
    • Expand the work we do with companies that have ‘green’ initiatives

ES3 continues to maintain environmentally conscious work practices that include paper, metal, and plastic recycling. ES3 working to reduce our purchase of items that are packaged with single use plastics.

Offsetting our Carbon Footprint

At this time, ES3 does not to purchase carbon credits through the voluntary compliance markets.  Instead, ES3 has chosen to mitigate our carbon footprint by making contributions to institutions researching energy advancement and climate science.
