Not Yet on Track to Net Zero: The Urgent Need for Greater Ambition and Policy Action to Achieve Paris Temperature Goals
Mr. Simon Black, Ian Parry, Mr. James Roaf, and Karlygash Zhunussova
Achieving the Paris Agreement’s temperature goals requires cutting global CO2 emissions 25 to 50 percent this decade, followed by a rapid transition to net zero emissions. The world is currently not yet on track so there is an urgent need to narrow gaps in climate mitigation ambition and policy. Current mitigation pledges for 2030 would achieve just one to two thirds of the emissions reductions needed for limiting warming to 1.5 to 2oC. And additional measures equivalent to a global carbon price exceeding $75 per ton by 2030 are needed. This IMF Staff Climate Note presents extensive quantitative analyses to inform dialogue on closing mitigation ambition and policy gaps. It shows purely illustrative pathways to achieve the needed global emissions reductions while respecting international equity. The Note also presents country-level analyses of the emissions, fiscal, economic, and distributional impacts of carbon pricing and the trade-offs with other instruments—comprehensive mitigation strategies will be key.

Border Carbon Adjustments: Rationale, Design and Impact
Mr. Michael Keen, Ian W.H. Parry, and Mr. James Roaf
This paper assesses the rationale, design, and impacts of border carbon adjustments (BCAs). Large disparities in carbon pricing between countries raise concerns about competitiveness and emissions leakage. BCAs are potentially the most effective domestic instrument for addressing these challenges—but design details are critical. For example, limiting coverage of the BCA to energy-intensive, trade-exposed industries facilitates administration, and initially benchmarking BCAs on domestic emissions intensities would ease the transition for trading partners with emission-intensive production. It is also important to consider how to apply BCAs across countries with different approaches to emissions mitigation. BCAs alone do not solve the free-rider problem in carbon pricing, but might be a step to an effective international carbon price floor.

Carbon Pricing: What Role for Border Carbon Adjustments?
Ian W.H. Parry, Mr. Peter Dohlman, Mr. Cory Hillier, Mr. Martin D Kaufman, Florian Misch, Mr. James Roaf, Mr. Christophe J Waerzeggers, and Miss Kyung Kwak
This Climate Note discusses the rationale, design, and impacts of border carbon adjustments (BCAs), charges on embodied carbon in imports potentially matched by rebates for embodied carbon in exports. Large disparities in carbon pricing between countries is raising concerns about competitiveness and emissions leakage, and BCAs are a potentially effective instrument for addressing such concerns. Design details are critical, however. For example, limiting coverage of the BCA to energy-intensive, trade-exposed industries facilitates administration, and initially benchmarking BCAs on domestic emissions intensities would help ease the transition for emissions-intensive trading partners. It is also important to consider how to apply BCAs across countries with different approaches to emissions mitigation. BCAs are challenging because they pose legal risks and may be at odds with the differentiated responsibilities of developing countries. Furthermore, BCAs provide only modest incentives for other large emitting countries to scale carbon pricing—an international carbon price floor would be far more effective in this regard.

Still Not Getting Energy Prices Right: A Global and Country Update of Fossil Fuel Subsidies
Ian W.H. Parry, Mr. Simon Black, and Nate Vernon
This paper provides a comprehensive global, regional, and country-level update of: (i) efficient fossil fuel prices to reflect their full private and social costs; and (ii) subsidies implied by mispricing fuels. The methodology improves over previous IMF analyses through more sophisticated estimation of costs and impacts of reform. Globally, fossil fuel subsidies were $5.9 trillion in 2020 or about 6.8 percent of GDP, and are expected to rise to 7.4 percent of GDP in 2025. Just 8 percent of the 2020 subsidy reflects undercharging for supply costs (explicit subsidies) and 92 percent for undercharging for environmental costs and foregone consumption taxes (implicit subsidies). Efficient fuel pricing in 2025 would reduce global carbon dioxide emissions 36 percent below baseline levels, which is in line with keeping global warming to 1.5 degrees, while raising revenues worth 3.8 percent of global GDP and preventing 0.9 million local air pollution deaths. Accompanying spreadsheets provide detailed results for 191 countries.

Implementing the United States’ Domestic and International Climate Mitigation Goals: A Supportive Fiscal Policy Approach
Ian W.H. Parry
The United States has pledged to become carbon neutral by 2050, meet sectoral objectives (e.g., for carbon free power, electric vehicles) and encourage greater mitigation among large emitting countries and of international transportation emissions. Fiscal policies at the national, sectoral, and international level could play a critical role in implementing these objectives, along with investment, regulatory, and technology policies. Fiscal instruments are cost-effective, can enhance political acceptability, and do not worsen, or could help alleviate, budgetary pressures. Domestically, a fiscal policy package could contain a mix of economy-wide carbon pricing and revenue-neutral feebates (i.e., tax-subsidy schemes) with the latter reinforcing mitigation in the transport, power, industrial, building, forestry, and agricultural sectors. Internationally, a carbon price floor among large emitters (with flexibility to implement equivalent measures) could effectively scale up global mitigation, while levies/feebates offer a practical approach for reducing maritime and aviation emissions.

Global Fossil Fuel Subsidies Remain Large: An Update Based on Country-Level Estimates
Mr. David Coady, Ian W.H. Parry, Nghia-Piotr Le, and Baoping Shang
This paper updates estimates of fossil fuel subsidies, defined as fuel consumption times the gap between existing and efficient prices (i.e., prices warranted by supply costs, environmental costs, and revenue considerations), for 191 countries. Globally, subsidies remained large at $4.7 trillion (6.3 percent of global GDP) in 2015 and are projected at $5.2 trillion (6.5 percent of GDP) in 2017. The largest subsidizers in 2015 were China ($1.4 trillion), United States ($649 billion), Russia ($551 billion), European Union ($289 billion), and India ($209 billion). About three quarters of global subsidies are due to domestic factors—energy pricing reform thus remains largely in countries’ own national interest—while coal and petroleum together account for 85 percent of global subsidies. Efficient fossil fuel pricing in 2015 would have lowered global carbon emissions by 28 percent and fossil fuel air pollution deaths by 46 percent, and increased government revenue by 3.8 percent of GDP.

How Large Are Global Energy Subsidies?
Mr. David Coady, Ian W.H. Parry, Louis Sears, and Baoping Shang
This paper provides a comprehensive, updated picture of energy subsidies at the global and regional levels. It focuses on the broad notion of post-tax energy subsidies, which arise when consumer prices are below supply costs plus a tax to reflect environmental damage and an additional tax applied to all consumption goods to raise government revenues. Post-tax energy subsidies are dramatically higher than previously estimated, and are projected to remain high. These subsidies primarily reflect under-pricing from a domestic (rather than global) perspective, so even unilateral price reform is in countries’ own interests. The potential fiscal, environmental and welfare impacts of energy subsidy reform are substantial.

Natural Gas, Public Investment and Debt Sustainability in Mozambique
Mr. Giovanni Melina and Yi Xiong
Mozambique has great potential in natural gas reserves and if liquefied/commercialized the sum of taxes and other fiscal revenue from natural gas will, at its peak, reach roughly one third of total fiscal revenue. Recent developments in the natural resource sector have triggered a fresh round of much needed infrastructure investment. This paper uses the DIGNAR model to simulate alternative public investment scaling-up plans in alternative LNG market scenarios. Results show that while a conservative approach, which simply awaits LNG revenues, would miss significant current growth opportunities, an aggressive approach would likely meet absorptive capacity constraints and imply a much bigger (and, in an adverse scenario, unsustainable) build-up of public debt. A gradual scaling up approach represents indeed a desirable path, as it allows anticipating some, though not all, of the LNG revenue and, even in an adverse scenario, keeping public debt at sustainable levels. Structural reforms affecting selection, governance and execution of public investment projects would significantly enhance the extent to which public capital is accumulated and impact non-resource growth and, ultimately, debt sustainability.

Emergence of the Gulf of Guinea in the Global Economy: Prospects and Challenges
Damian Ondo Mañe
The Gulf of Guinea's tremendous potential is creating investment opportunities for the region. Some of its resources, such as oil, minerals, and forests, continue to attract significant investments whereas others, like natural gas, could be exploited to their full potential if necessary investments were undertaken. Nevertheless, the Gulf of Guinea has to cope with numerous challenges, both exogenous and endogenous, before it can fully benefit from its riches. One of these problems stems from the overwhelmingly weak institutions and governance, pointed by stylized facts, which add to the risks of "natural resource curse" and can feed the theory of the "Paradox of Plenty." The case is made that regional institutional arrangements and increased involvement of the international community and the African Diaspora should complement the efforts in which countries in the region should engage to address policy and governance issues. Complementary avenues are proposed, including maintaining stability and security, making better use of the region's own assets, putting in place a favorable business environment, and augmenting exports with value addition.
