Subsidies are unrequited payments from government to non-government units. They can take several forms:
- Current unrequited payments based on levels of production or on the quantities or values of goods or services produced, consumed, sold or imported.
- Lump-sum payments from government to non-government units that are not based on quantities or prices (e.g. energy vouchers, agricultural land payments), even though they do not change prices at the margin.
- Performance-based subsidies that involve transactions from government to non-government units, where the latter provides a specific climate-relevant service in return for the payment, such as carbon sequestration or biodiversity protection (e.g. payments for ecosystem services).
- Concessional loans through which a government unit lends to non-government units at intentionally below-market interest rates or provides loan guarantees or other financial risk-mitigation mechanisms, for the production, consumption, sales or import of goods or services.
- Feebates, combining a fee on high levels of GHG emissions products or activities with a rebate to producers or users of low emissions alternatives.
This excludes spending by a government unit towards forming fixed capital such as transport and energy infrastructure, or nature-based infrastructure solutions, as well as intangible assets such as research and development (R&D).
