Denmark has a highly ambitious goal of reducing greenhouse gas emissions 70 percent below 1990 levels by 2030. While there is general agreement that carbon pricing should be the centerpiece of Denmark’s mitigation strategy, pricing needs to be effective, address equity and leakage concerns, and be reinforced by additional measures at the sectoral level. The strategy Denmark develops can be a good prototype for others to follow. This paper discusses mechanisms to scale up domestic carbon pricing, compensate households, and possibly combine pricing with a border carbon adjustment. It also recommends the use of revenue-neutral feebate schemes to strengthen mitigation incentives, particularly for transportation and agriculture, fisheries and forestry, though these schemes could also be applied more widely.

Pacific island countries (PICs) are vulnerable severe natural disasters, especially cyclones, inflicting large losses on their economies. In the aftermath of disasters, PIC governments face revenue losses and spending pressures to address post-disaster relief and recovery efforts. This paper estimates the effects of severe natural disasters on fiscal revenues and expenditure in PICs. These are combined with information on the frequency of large disasters to calculate the rate of budgetary savings needed to build appropriate fiscal buffers. Fiscal buffers provide self-insurance against natural disaster shocks and facilitate quick disbursement for recovery and relief efforts, and protection of spending on essential services and infrastructure. The estimates can provide a benchmark for policymakers, and should be adjusted to take into account other sources of financing, as well as budget risks from less severe as well as more frequent disasters.
France is the top agricultural producer in the European Union (EU), and agriculture plays a prominent role in the country’s foreign trade and intermediate exchanges. Reflecting production volumes and methods, the sector, however, also generates significant negative environmental and public health externalities. Recent model simulations show that a
well-designed shift in production and consumption to make the former sustainable and align the latter with recommended values can curb these considerably and generate large macroeconomic gains. I propose a policy toolkit in line with the government’s existing sectoral policies that can support this transition.
The pan-Canadian approach to carbon pricing, announced in October 2016, ensures that carbon pricing applies throughout Canada in 2018, with increasing stringency over time to reduce emissions. Canadian provinces and territories have the flexibility to either implement an explicit price-based system—with a minimum price of CAN $10 per tonne of carbon dioxide equivalent in 2018, increasing to CAN $50 per tonne by 2022—or an equivalently scaled emissions trading system. This paper discusses the rationale for, and design of, the price floor requirement; its (provincial-level) environmental, fiscal, and economic welfare impacts; monitoring issues; and (national-level) incidence. The general conclusion is that the welfare costs and implementation issues are manageable, and pricing provides significant new revenues. A challenge is that the floor price by itself appears well short of what will be needed by 2030 for Canada’s Paris Agreement pledge.

This paper calculates, for the top twenty emitting countries, how much pricing of carbon dioxide (CO2) emissions is in their own national interests due to domestic co-benefits (leaving aside the global climate benefits). On average, nationally efficient prices are substantial, $57.5 per ton of CO2 (for year 2010), reflecting primarily health co-benefits from reduced air pollution at coal plants and, in some cases, reductions in automobile externalities (net of fuel taxes/subsidies). Pricing co-benefits reduces CO2 emissions from the top twenty emitters by 13.5 percent (a 10.8 percent reduction in global emissions). However, co-benefits vary dramatically across countries (e.g., with population exposure to pollution) and differentiated pricing of CO2 emissions therefore yields higher net benefits (by 23 percent) than uniform pricing. Importantly, the efficiency case for pricing carbon’s co-benefits hinges critically on (i) weak prospects for internalizing other externalities through other pricing instruments and (ii) productive use of carbon pricing revenues.
Gasoline and diesel fuel are heavily taxed in many developed and some emerging and developing countries. Outside of the United States and Europe, however, there has been little attempt to quantify the external costs of vehicle use, so policymakers lack guidance on whether prevailing tax rates are economically efficient. This paper develops a general approach for estimating motor vehicle externalities, and hence corrective taxes on gasoline and diesel, based on pooling local data with extrapolations from U.S.evidence. The analysis is illustrated for the case of Chile, though it could be applied to other countries.
Fiscal instruments are potentially among the most effective, and cost-effective, options for addressing externalities related to poor air quality, urban road congestion, and greenhouse gases. This paper takes a case study, focused on Mauritius (a pioneer in the use of green taxes) to illustrate how existing taxes, especially on fuels and vehicles, could be reformed to better address these externalities. We discuss, in particular, an explicit carbon tax; a variety of options for reforming vehicle taxes to meet environmental, equity, and revenue objectives; and a progressive transition to usage-based vehicle taxes to address congestion
Negotiations toward a successor to the Kyoto Protocol on climate change have come to a critical point, and domestic climate policies are being developed, as the world seeks to recover from the deepest economic crisis for decades and looks for new sources of sustainable growth. This position paper considers the challenge posed by these two policy imperatives: how to exit from the crisis while developing an effective response to climate change. Blending the objectives of a sustained recovery and effective climate policies presents both challenges and opportunities. Although there are potential “win-win” spending measures conducive to both, the more fundamental linkages and synergies lie in the broader strategies adopted toward each other. Greater climate resilience can promote macroeconomic stability and alleviate poverty; and carbon pricing, essential for mitigation, can contribute to the strengthening of fiscal positions that is expected to be needed in many countries. There are, nevertheless, also difficult trade-offs to face, notably in the somewhat greater caution now warranted in moving to more aggressive emissions pricing. However, the simple policy guidelines for addressing climate issues remain fundamentally unchanged; the need to deploy a range of regulatory, spending, and emissions pricing measures.
