Impacts to be offset include:

  • Emissions associated with natural gas used to operate Safeco Field on April 22 (1,584 Therms of natural gas),
  • 138,220 gallons of water (185 CCF)
  • Disposal or recycling of waste generated during the game (estimated to be 5.5 tons, 90%+ of which will be recycled)
  • 47,000 kilowatt hours of electricity
  • Air travel emissions for the Astros from Houston to Seattle and on to Oakland, as well as the air travel emissions for the umpire crew from San Francisco to Seattle and on to Milwaukee.
