A carbon price and increased use of other forms of true-value pricing is one of the deliverables necessary by 2020 in WBCSD Vision 2050, a scenario for a sustainable future. We need a pricing for goods and services that includes their full cost and benefits. In the case of a carbon price, this value reflects the impact of CO2 emissions on the environment. Establishing a carbon price, implicitly or explicitly, is potentially one of the most powerful mechanisms available to reduce national greenhouse gas emissions. The goal of carbon pricing is to create a change in the economy, whereby the market begins to differentiate between goods and services on the basis of their carbon footprints.
