Why do I say that? Well, two reasone come to mind:
1. You need a proper virtual conference space built to do this - now perhaps Stonefield or a similar co. might do this as part of a sponsorship deal and that would sort that one but the second reason
2. is that there is very low general awareness of virtual worlds, never mind the use of them as virtual conference venues.

I guess it depends on who your target audience for the conference is. If it is Joe Consumer, then it would be very difficult but if your audience is a more tightly focussed group, they could be educated on the virtual conference idea and it might work.

I with you. I need to buy a car at the moment only because I am moving to Spain and will need one there.

Otherwise I’d hold off until there were a decent zero emissions option available.

Could such a conference be held virtually and would the experience be good enough for attendees to benefit?

The key researchers and therefore best available speakers are located on the west coast of the USA. A virtual conference would be the easiest(and most carbon efficient) way to hold such an event. Would it work?

I agree with your sentiments. I drive a Prius but it still produces > 100 grams of CO2 per km. Our second car is a Cireon. Ideally we would like a plug in hybrid electric for long journers and a pure electric for dropping the kids to school. With demand response technology to charge these cars we would be running on a very large percentage of renewable energy. We are not going to buy new cars until something more ecologically sound is available.

There are two good reasons for not buying cars at the moment. Given that there will be a huge change in technology over the next five years it is a good thing to let our car population age so that we can adopt the new technologies faster. And, secondly, if the car companies see a drop in sales as people wait for newer greener models
then this will accelerate their development.

The greatest technological barrier remains the low energy density of batteries.

In all fairness to GM, I think they have plans to move toward electric vehicles.

Personally, I think BMWs recent marketing campaigh around ‘Efficient Dynamics’ is just that; a marketing campaign. When will they bring a hybrid or plug in hybrid electic vehicle (PHEV) to market?

We’ll launch a great project about sustainable development in a near future. I’ll tell you more as soon as possible.
