The typical event can reduce its carbon footprint by 90 percent by hosting the meeting virtually, according to research from ClimatePath.
Travel-related activity, such as air miles, airport transfers, driving and hotel, can account for up to 90 percent of the carbon footprint of many an event.
Dave Rochlin of ClimatePath said that most events can generate more than a ton of CO2 per attendee, whether it's a business meeting or the Super Bowl.
He said that regional events can be up to 70 percent less emissions intensive.
"Selecting a central location with good public transportation options can make a big difference," he said.
One company, Manpower, avoided 400,000 pounds of CO2 emissions by holding its annual Global Leadership Team meeting virtually, which reduced air travel by one million miles.
