The range of technologies used in the compliance regime are eligible in the voluntary market, as well as others not currently accepted, such as certain forestry, land use and transport methodologies. VER projects also have no geographical limitation and can be generated from projects globally.
As with the compliance regime, there are two main types of transactions, Spot and Forward. Spot transactions are carried out for VERs, which have already been generated and have completed or are in the process of verification by an independent third party. A spot transaction can be arranged based on current prices, as long as VER delivery is expected within approximately three months. Forward transactions are carried out for VERs with a generation schedule over several years, typically up to 2012.
