The most sustainable journey is arguably the one not taken!  By avoiding unnecessary personal or business travel in the first place can reduce the potential environmental impacts associated with that travel.

The improvement of technologies that allow remote working and virtual meetings can help avoid a lot of unnecessary business travel, reducing greenhouse gas emissions, as well as saving travel time and costs.  A 2012 study suggests 60% of office based employees could be regularly working from home in the next decade as a result of technological advances in the workplace.  High speed broadband, smartphones, social media and software for virtual meetings by video have all helped the growth in home and remote working.
