Possibilities:

Travel to and from the conference:

• Offset green house gas (GHG) emissions associated with your travel
• Book your travel via the most direct route possible as multiple take-offs and landings cause substantial increases in emissions
• Utilize public transit bus shuttles from the airport to your hotel to reduce GHG emissions

At the conference:

• Recycle your bottles, cans and paper at recycling
  stations throughout the conference and exhibition centre to reduce waste
• When printing or copying materials, make sure to print double-sided versions
• Bring your own reusable mug, water bottle, pen and pencil
• Collect business cards of presenters/exhibitors and have them e-mail reports and other information rather than collecting printed hand-outs (presentations will be available on the ERAPPA Conference website proceeding the conference)
• When attending the exhibition, take only what information you really require

At your hotel room:

• Turn off any lights, TV, air conditioner or heaters when you leave your hotel room for the day to decrease energy consumption
• If your accommodation offers this service, take the option of not having sheets and towels changed every day to reduce consumption of energy, water and soap

While in Ottawa:

• Do your sightseeing by foot, by rental bike (RentABike) or public transit (Ottawa Public Transportation)
