2018 SUSTAINABILITY REPORT

Understanding our impact to
enhance operational efficiency
and conserve resources across
our operations

Environmental Footprint

Defining and mitigating our impact on the environment is the most critical aspect of our sustainability performance. Each ESCO subsidiary, through the employees who serve on the ESCO Sustainability Council helps to set goals for development and implementation of energy efficiency initiatives. Many of these goals involve improvements in energy management at our facilities.

Our efforts to conserve energy and reduce greenhouse gas emissions (GHG) have focused on modifications, upgrades and improvements to our facilities and to our manufacturing processes. Members of the Sustainability Council at each subsidiary have led the charge to develop and implement these initiatives. We are proud to report on these activities and look forward to continuing to build upon our progress and find new ways to improve the sustainability of our businesses in the years ahead. Some highlights of facility improvements this year include:

  • Solar Collection.
    • PTI in Oxnard, California is our second facility to embrace a significant investment in solar collectors, NRG being the first. In 2017-18, PTI installed 2636 solar collector panels positioned on the roof and over the parking areas. These panels generate approximately 828 kw/dc. The system is expected to generate approximately 1,300,000 kWh of clean electricity for each year of operation. This is equivalent to the following for every year the system in on-line: (i) removal of 207 passenger vehicles from the road; (ii) 1,058,000 lbs. of coal burner; or (iii) CO2 absorbed by 1.1 acres of forest.
  • Lighting Replacement. Throughout ESCO, our facilities have or are in the process of replacing lighting with more energy efficient LED bulbs.
    • Westland changed its entire plant to LED lighting in 2018.
    • PTI installed new lights and timers in conjunction with their solar installation.
    • ETS has replaced approximately 105 of 225 light fixtures (56% of its total) with LED lights in its Cedar Park location. Only one new light is needed for every 3-4 existing light fixtures. The new lights are 40% more energy efficient.
    • ETS has replaced 30-40% of its lights with LED lights in its Durant, Oklahoma plant. Each new light replaces 9 old lights and is 30-40% more energy efficient.
    • Plastique doubled the size of its facility in Poland. For the new space, all LED lights were used as well as photocells for automatic turn off in most areas. Plastique also updated the lighting in its warehouse to LED and introduced LED lighting in its UK facility saving 4.4 tons in carbon emissions per year.
    • Crissair converted all of the administrative areas in its plant, which comprise approximately 40% of the total space, to LED lights with motion sensors.
    • TEQ replaced the mercury vapor lights in production areas with LED lights with motion sensors. This replacement reduced its electrical usage by 15%. The local utility company recognized this accomplishment by giving TEQ a rebate on its electric bill.
  • Automatic Thermostats.
    • ETS replaced 24 of its thermostats and put them on a phone application so that maintenance personnel can regulate needs and turn off A/C when it is not needed.
  • Recycling.
    • ETS initiated several new recycling efforts including forming new agreements with companies that recycle its scrap metal and old computer equipment. ETS also has recycling programs for wood, metal and cardboard.
    • Mayday initiated a new recycling program in May 2018 where it separates paper, plastic and aluminum cans for recycling. Mayday also improved its scrap metal sorting which makes its scrap more appealing to recyclers.
    • Freemont has begun to recycle its polystyrene and now recycles over 2 tons of polystyrene per week.
    • VACCO has redesigned its etching process for ferric chloride and is now recycling approximately 20,000 gallons of materials. Since October 2018, VACCO has recieved a monthly fuel recycling certification.
  • Other
    • TEQ has recently commenced construction of a 48,600 square foot addition to its plant in Huntley, IL to add an extrusion line and warehouse space. Completion is expected in June 2019. The new addition will reduce the number of trucks required to bring in raw materials which can now be stored in the new warehouse. The addition will use LED lighting throughout and outside ventilation rather than cooling for temperature control. It is expected to be one of the most energy efficient extrusion plants in the United States.
    • ETS completed a 12,000 square foot addition to its facility in Cedar Park, Texas in August 2017. The new space includes a warehouse which eliminated 3 external storage warehouses. The new warehouse eliminates the need to transport raw materials back and forth from these external locations. ETS is also moving to a new more energy efficient in Beijing, China with an expected move in date of early 2019. The new facility has all LED lighting and more efficient heating systems. In addition, ETS did some internal restructuring resulting in closure of factories in Germany and the UK and consolidation of those operations in Cedar Park and Finland. These reorganizations were energy positive for operations. ETS also replaced its waste water evaporator with a newer more efficient version and reengineered its air conditioning in Cedar Park, based on suggestions from an audit done by the local electric company. ETS now stages the startup of its air conditioning units so that only 5 units are activated at a time in 30 minute intervals. This saves significant amounts of energy at peak times. ETS also replaced 5 furnaces in 2017 and 2018 in Durant.
    • Westland was the subject of a comprehensive federal and state environmental review to look at its waste generation and handling practices. The audit gave Westland an outstanding report and found that it was operating within best practices.
Environmental Management at ESCO

This year we automated the process of gathering our data by licensing software to automatically collect our electric utility data and calculate our greenhouse gas emissions.

We collected the utility information from each ESCO facility in excess of 10,000 square feet to match our 10k reporting. This task required a significant number of man hours from each participating site. We now have visibility into and the ongoing collection of data from 54 different utility providers and 94 separate utility accounts across the globe. The resulting information allows us to more easily quantify, monitor, and seek ways to reduce our GHG emissions in a timely manner. Going forward we plan to include water consumption, natural gas and propane in this automated process and ultimately waste.


Energy Consumption & Greenhouse Gas Emissions – The Numbers

This is the third report we have competed to document our GHG emissions. Due to the new collection method and the new baseline of including only facilities in excess of 10,000 square feet, we cannot compare usage numbers to the previous two years. Going forward the numbers will be more directly comparable. The tables and graphs below reflects our usage of electricity for facilities exceeding 10,000 square feet for 2017.

Calendar Year 2017
Total Energy Consumption (MWh) 61,737
Total GHG Emissions (MTCO2e) 30,133
Direct Greenhouse Gas Emissions 3,429
Indirect Greenhouse Gas Emissions (Scope 2) 26,831
Energy Intensity (MWh/sq.ft.) 47
GHG Intensity (MTCO2e/sq.ft.) 19






Our efforts to conserve energy are described throughout this report. We are proud of our efforts, upgrades, new solar collection system and manufacturing process and product improvement efficiencies. We will continue to build on this momentum in the coming years while continuing our efforts at maximizing data collection efficiencies while remaining transparent to our stakeholders.
