29. How many household members use video-conferencing, tele-commuting, or similar, whenever possible? (instead of always travelling to the office, to meetings, etc.)
For many jobs, you just have to be there, but working from home sometimes, if you can, reduces your transport emissions. Perhaps you can log in to your work computer from home and spend the day doing whatever you would have done if you were at the office.
If you have the sort of job that involves interstate or overseas travel for business meetings, you can ask your company to install video-conferencing equipment so that you can have virtual meetings without leaving your office. Aircraft emissions are particularly damaging because they occur at high altitudes, so any IT investments that reduce the need to travel are very worthwhile.
