Conserving Natural Resources and Reducing Waste


At our Energy Star certified Corporate Headquarters in Worcester, Massachusetts, we have made numerous energy investments, including:

  • 100 percent wind power for electrical consumption at our 800,000 square foot facility, equating to over 80 percent of the entire electricity demand across our entire 1,400,000 square foot U.S. office portfolio
  • An ice harvesting thermal storage program to keep our facility cool and conserve approximately 400,000 KwH per year
  • Parking garages equipped with LED lighting on motion sensor controls
  • Charging stations for electric cars
  • A data center cooled with outside air when the exterior temperature falls below 40° 
  • Fan systems operating on high efficiency, variable speed drive motors
  • Continuous commissioning energy management systems to resolve operating problems and optimize energy use
  • White roofs on buildings to lower heating and cooling requirements, also at our other major campus in Howell, Michigan

In addition, the company's U.S. field offices include four LEED-certified and 11 Energy Star buildings, and seven additional buildings that have earned both certifications.


  • Recycling and composting program includes approximately 60 tons of single-stream, co-mingled recycling, 54 tons of on-site document destruction, 7 tons of composted material, and 26 tons of construction and demolition material, which diverts 38 percent of the total waste stream away from landfills
  • Our cafeteria offers 100 percent compostable and/or recyclable dining materials
  • A comprehensive paper shredding and recycling program in each of our Hanover-owned offices
  • A vendor partnership to clear all computer hard drives of sensitive data with the remainder of our computer equipment recycled
  • A bulb and battery recycling program, resulting in approximately 2,500 bulbs and 350 pounds of batteries recycled annually at our Worcester and Howell facilities

Additionally, in conjunction with our Hanover 2021 strategic plan, we strive to identify new ways to leverage technology to reduce paper, resources and gas/carbon emissions.


  • Automatic water cut-off sensors and ultra-low flow water aeration restrictions throughout our buildings
  • Landscape irrigation water sourced entirely from an onsite well to reduce water treatment needs
  • Filtered water filling stations at our corporate headquarters, conserving the equivalent of more than 120,000 plastic water bottles in less than a year's time


  • A partnership with MassRIDES, a ride-matching service sponsored by the Massachusetts Department of Transportation encouraging employees to walk, bike, telecommute, carpool, vanpool, utilize transit or work a compressed week, including tax benefits for qualifying transportation expenses
  • Flexible work schedules and remote work, helping to reduce carbon emissions associated from commuting
  • Environmentally friendly fertilizers used for all landscaping at our headquarters
  • Donations of used office furniture and supplies so they can be reused
  • Community supported agriculture (CSA) program for employees to support local, sustainable agriculture
