The Y-factor visualizes the complexity of climate change abatement. There is a wide variety of technologies to reduce greenhouse gas emissions, spread throughout all sectors of the economy. Abatement options are typically presented in terms of the abatement costs and abatement potential, in a so-called marginal abatement cost curve (MACC). The abatement potential represent the emissions that can be avoided (ton CO2) with this abatement measure. The abatement costs represent the costs needed to reduce reduce a tonne of greenhouse gas emissions (Euro/ton CO2).
But there is more to it than Euro's and tons. Although costs important, low-cost options are not necessarily easy to realize. Many other factors also play a role. Understanding why some abatement measures are adopted and others is a complicated matter. Lot's of different things appear to play a role for lot's of abatement options - an understanding of a wide variety of complex interacting systems including the technologies and infrastructures, the behavior of many stakeholders rules, local conditions and rules and regulations is necessary.
