Fiscal frameworks influence behaviour by means of government revenue and spending, and comprise both positive and negative price incentives. Examples for positive are tax exemptions, subsidies or credits that can stimulate circular goods and services. Examples for negative price incentives are taxes, penalties or charges which impede and disincentivize an undesired, linear activity.
