Green Seminar Series

Academics emit between 10 and 30 tons of CO2 per year through flying. That’s a lot! A round trip from New York to Geneva in business class generates 2-3 tons of CO2, about the same amount each of us produces per year for food. International interactions are essential to share knowledge and technologies, but does scientific progress have to come at such a high carbocost?


Zoom provides a Unified Meeting Experience platform that brings HD video conferencing, mobility and web meetings together as a cloud service. A crystal-clear video conversation and high quality screen sharing with up to 25 people or rooms. It is available for Windows, Mac, iOS, Android.


Go to Zoom Download and download Zoom. After the install you can enter your first, last name and your e-mail address to sign up.

  • Use the desktop installment.
  • Find quiet room.
  • Use a fast wired network connection (avoid Wifi).
  • Wall mount power supply for your PC (to avoid battery issues).
  • We recommend diffuse lighting from the front (e.g. window). We do not recommend lighting from behind or above (neons), because this causes underexposed and poorly lit faces.
  • A neutral and static background helps to reduce distractions during the talk.
  • Some people prefer giving the presentation while standing. This significantly improves the intonation and makes the presentation more dynamic.


After you launch the app, you have two options, Join a meeting, or Host a meeting. If you do not wish to log in, and just want to join a meeting in progress click on Join a meeting. If you would like to log in and start you own meeting, click on Host a meeting.

Join a meeting


Select "Join a meeting".



Enter meeting ID(this is displayed in the email invitation) and password if prompted.



Click on Join.

Host a meeting


Click either the Start without video or Start with video button, depending on your needs.



Click the Invite button at the bottom of the meeting window.



You can share the invitation in a few different ways:

  • Clicking the Copy URL button, then paste the URL into an email message to the participants you wish to invite.
  • Click the Copy invitation button, then paste the message into an email to the participants you wish to invite.
  • Click one of the email service buttons. Your chosen email service will appear with a preformatted invitation.

Before your meeting

Network connection.

Connect your computer to a wired network. Bandwidth is possibly the most important asset to a successful video conference call.

The yellow bar for download and upload should be above 1.2Mbps for one-on-one meetings. A group(for example 5) zoom meeting should be above 20Mbps.

Optimize Zoom.

  • To optimize video quality go to the start video arrow on the lower left side. Select Video settings....

  • Select Enable HD and Touch up my appearance.

Control video and audio quality.

Invest in a quality webcam and speaker and microphone headset. These provide better video and audio than your computer’s built-in system. Try to hold meetings in quiet, indoor locations to control ambient noise.

Adjust your lighting.

Don’t sit directly in front or beside a bright light source, or else all the audience sees is a bright light and a shadowy figure. Experiment with moving lamps and your camera until you can see your brightly-lit face on the screen.

Think about your background.

Try to provide a nice, plain background. You can’t control everything in a mobile environment, but you should give some thought to background prior to your meeting.

During your meeting

Mute your microphone when necessary.

Zoom has a “Mute Microphone” option that cuts down on ambient feedback for the audience. When there is a lot of back-and-forth discussion you will turn this off, but you should mute yourself when listening to a presenter.

Use Zoom’s chat function.

You can send a question or statement to everyone or privately to a participant Think about your actions on camera.
