Description

GCAM operates by determining a set of prices that ensure supply is equal to demand for all time steps. The marketplace collects the supplies and demands and uses solver algorithms to determine those prices.

Policy options

This section summarizes some of the marketplace policy options available in GCAM.

Carbon or GHG prices

GCAM users can directly specify the price of carbon or GHGs. Given a carbon price, the resulting emissions will vary depending on other scenario drivers, such as population, GDP, resources, and technology. See example.
