Video conferencing has been around for a surprisingly long time. AT&T ran the first call in 1927. Since then, pundits have been consistently predicting that video conferencing was just about to take off. They have been wrong for eighty years. Why should we believe the techno-optimists now?
In the last year, several companies have launched video conferencing products that provide an experience similar to real meetings. The quality is surprising and even sceptics have begun to see the advantages of using a meeting room for an hour rather than spending three days going to Hong Kong and back. Cisco’s Telepresence product is generating enthusiasm that is tempered by the enormous costs of setting up the equipment and providing the bandwidth. But the company says that prices will fall dramatically over the next few years.
Is this going to be enough to get people out of planes? The signs are good. Even low bandwidth alternatives suitable for home use are getting praise from the experts. So if Cisco doesn’t make video conferencing work, Bay Area start-ups like VSee will probably start eating into the market for lower cost products.
Only 1% of imported organic food comes by air. But the Soil Association says that air freight ‘can generate 177 times’ the CO2 of shipping. Air transport is necessary for some fruit and delicate vegetables which provide a vital source of income in some poor countries.
The Pre-Budget review in early October disappointed green activists. Environmental measures formed a small fraction of the government’s initiatives. It doesn’t look as though Alistair Darling sees climate change as one of the priorities of this administration. But there were two important commitments: a revision to Air Passenger Duty (APD) and (via BERR) a competition to run a commercial-scale carbon capture project.
Both the Conservative and Lib Dem parties have produced position papers on climate change in the last few weeks. The Conservative document is over 500 pages long but contains very few specific proposals. To be harsh, it is little more than a prolonged agonising over whether the climate change problem can be addressed using conventional free-market mechanisms. The Lib Dem paper is a tenth of the length but does contain the outlines of a coherent set of policies.
In early September, researchers from the Tyndall Centre in the UK put out a report that said that incorporation of the airline industry into the Emissions Trading Scheme (ETS) will not provide significant incentive to cut emissions. The big polluters today are paying about €20 per tonne for their emissions. When aviation joins the scheme in 2012, this price would add about €5 for a flight to Barcelona. Tyndall argues that the EU and national governments cannot escape the conclusion that the ETS is not enough and that aviation must be constrained by other fiscal or legislative measures as well as by inclusion in the carbon tax net.
