This report provides a useful summary of tax and non-tax incentives in use in 31 countries, which may be helpful for developing country policymakers who wish to see which incentive measures are being used in other countries, as a starting point for comparative analysis.

This note provides a basic introduction to the use of incentives to support renewable energy investments. It is included here because it considers some general principles of when to use tax and nontax incentives, and outlines the main types of tax incentive (p. 3). The note briefly explores how tax and nontax incentives can be combined, and presents a short case study on how Spain combined tax and nontax incentives for renewable energy.

The Mirrlees Review was an extremely comprehensive review of the design of a good tax system. This chapter provides an overview of key economic issues in the use of taxation as environmental policy. Sections 5.2–5.4 discuss the economic principles of environmental taxation, reviewing the arguments for using taxes and other market mechanisms in environmental policy, the efficient design of environmental taxes, and the fiscal value of the revenue contribution from environmental taxes. Sections 5.5–5.8 apply these principles to four specific environmental tax areas—energy, road transport, aviation, and household waste.

This short briefing paper provides a basic introduction to the role of fiscal policy in the transition to greener economies, in particular the use of environmental taxes. It also briefly covers energy subsidy reform and introduces some lessons learned from experience of fiscal policy reform so far.

This policy guide introduces the use of taxes to achieve environmental outcomes. It outlines why countries might consider using environmental taxes (rather than, for example, subsidies), and then explores some principles for how to design effective environmental taxes, including defining the target and scope of the tax, and setting the rate. It also briefly covers how the revenues raised can be used, and how to overcome obstacles to implementing environmental taxes.

In Vietnam, investment incentives are provided in several ways, including taxation (e.g. favorable income tax rates), low import duties and fees, loss transfer, and accelerated depreciation of assets. This report assesses investment incentives for renewable energy in Vietnam. It focuses on small hydro, wind, solar, biogas, and biomass resources. Section 4.4 of the report provides an overview of the different tax measures in Vietnam’s investment incentive framework that apply to all sectors, and section 4.6.2 presents preferential tax incentives for renewable energy companies in Vietnam. The impact of different incentives is discussed in section 5, and conclusions are presented in section 6.
