- Putting a price on carbon dioxide and other greenhouse gases to curb emissions must be the centrepiece of any comprehensive climate-change policy. We know it works: pricing carbon creates broad incentives to cut emissions. Yet the current price of carbon remains much too low relative to the hidden environmental, health and societal costs of burning a tonne of coal or a barrel of oil1. The global average price is below zero, once half a trillion dollars of fossil-fuel subsidies are factored in.

The progress of GHG markets : opportunities and risks
- 2010

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The climate negotiations at the COP15 in December 2009 did not produce a new international treaty with binding emissions commitments but the Copenhagen Accord for dealing with post-2012 climate change. Given the current climate negotiation process it is unlikely that we will see a global climate agreement soon on a global cap between all Convention members participating in a single carbon market. We may be more likely to see a stepwise process moving towards this scenario, most likely involving linkages between different national policy programs when it comes to mitigation as well as offsetting emissions. In such a process countries will offer commitments based on their domestic abilities, preferences and policies, norms and institutions. National and sub-national policies are thus likely to be the de-facto building blocks of nations' abilities to make and fulfill international commitments. However, also with multilateral mitigation programs without binding commitments, carbon markets will be needed as well as international authorities that support measurement, reporting and verification rules and the international registries. Such markets will necessarily be complicated and temporary in a world without an overarching binding agreement. There will be numerous tradeoffs between different kinds of second-best arrangements. The purpose of this report is to build knowledge about the effects of the development of regional and international carbon markets and the auxiliary technology agreements that might be needed. Among the topics we address are: the evolution and integration of carbon markets, the impacts of policy and technology cost uncertainty on the cost of meeting targets through a carbon market mechanism, the effect of banking, price floors and ceilings, institutional constraints and technological change in the further development of carbon markets and their links to other environmental policy instruments, and the potential of REDD-plus to encourage sustainable forest development and climate mitigation.

Tradable performance standards in the transportation sector
- 2021

Ingår i: Energy Economics. - : Elsevier BV. - 0140-9883 .- 1873-6181. ; 102

Tidskriftsartikel (refereegranskat)abstract
- Performance standards have a long history in environmental policy. A performance standard sets a standard of technology performance but leaves technology choice to producers; it increases the relative costs of technologies with undesirable performance characteristics and lowers the costs of technologies with desirable characteristics. The primary motivations are to promote innovation, to address consumers' undervaluation of efficiency, and to reduce externalities, such as air pollution and the risks of dependence on foreign oil. In the past decade, trading has been incorporated (thus termed as tradable performance standard, TPS) into several U.S. transportation programs: regulations for greenhouse gas emissions from passenger cars and trucks (national), zero-emission vehicle programs (10 states), the Renewable Fuel Standard (national), and low-carbon fuel standards (two states). TPS allows for equalization of marginal costs across eligible technologies and is therefore more efficient than pure regulations. We show that sectoral TPS programs have high credit prices but low price effects on products and provide strong incentives for upstream innovation and technology transformation. Unlike emissions pricing, however, they do not have a strong output effect: consumers do not bear the full cost of the pollution and do not have incentive to reduce consumption of polluting products. Given that the expected carbon price may be too low to substantially affect transportation demand or technology change, combining TPS with a carbon price may be necessary to drive innovation and achieve a sustained low-carbon transformation in the sector.

Policy design for the Anthropocene

Tidskriftsartikel (refereegranskat)abstract
- © 2019, Springer Nature Limited. Today, more than ever, ‘Spaceship Earth’ is an apt metaphor as we chart the boundaries for a safe planet1. Social scientists both analyse why society courts disaster by approaching or even overstepping these boundaries and try to design suitable policies to avoid these perils. Because the threats of transgressing planetary boundaries are global, long-run, uncertain and interconnected, they must be analysed together to avoid conflicts and take advantage of synergies. To obtain policies that are effective at both international and local levels requires careful analysis of the underlying mechanisms across scientific disciplines and approaches, and must take politics into account. In this Perspective, we examine the complexities of designing policies that can keep Earth within the biophysical limits favourable to human life.

From Here to Sustainability – Is the Lisbon/Göteborg agenda delivering?
- 2004
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Executive Summary The European Councils held in Lisbon (2000) and in Göteborg (2001) gave the Union a new direction by establishing a long term strategy with sustainable development as the overarching objective. Sustainable development means, in this context, goals for economic, social and environmental policy, which are both mutually consistent and capable of delivering enhanced economic growth. To assure progress towards an agreed range of targets, the open method of coordination (OMC) has been adopted as the process for the implementation of the strategy. The strategy for sustainable development is a long-term one and, although the deadline originally set for the Lisbon agenda was 2010, it is clear that sustainable development has a much longer time-horizon and also that there is a global dimension to sustainable development, not just an EU one. In the run up to the mid-term review of the Lisbon strategy, this report by the European Panel for Sustainable Development, EPSD, offers an assessment of the EU approach to sustainable development. The report is based on official documents, research reports and background reports prepared by researchers from different disciplines. It concentrates on the EU-15 Member States, because the ten new members that acceded to the EU in May 2004 have not (yet!) been subject to the same commitments in relation to sustainable development. However, in future work by the EPSD, it is anticipated that the coverage will be extended to embrace all 25 Member States. The report starts with a discussion on the political process, followed by an examination of the economic, social and environmental dimensions of the strategy, of the potential of new technologies, and of the results delivered by the Member States. The final chapters include discussions on impact assessment and the global dimension of sustainable development. The focus of the report is on: − The integration of the three dimensions of sustai nable development and the policies that affect them into one coherent strategy − The implementation of the strategy through the open method of co-ordination The main messages of the report are that it is vital to: • Maintain the original commitment to sustainable development as the overarching objective of the Lisbon strategy and improve the co-ordination between the three pillars of the strategy: the economic, social and environmental dimensions [...]

The social cost of methane
- 2023
-
Ingår i: Climatic Change. - 1573-1480 .- 0165-0009. ; 176:6
-
Tidskriftsartikel (refereegranskat)abstract
- A rapid and sustained reduction of methane emissions has been proposed recently as a key strategy to meet the climate targets of the Paris Agreement. The social cost of methane (SCM), which expresses the climate damage cost associated with an additional metric ton of methane emitted, is a metric that can be used to design policies to reduce the emissions of this gas. Here, we extend the DICE-2016R2 model so that it includes an improved carbon cycle and energy balance model as well as methane emissions, methane abatement cost, and an atmospheric methane cycle explicitly to be able to provide consistent estimations of the SCM. We estimate the SCM to lie in the range 880–8100 USD/tCH4 in 2020, with a base case estimate of 4000 USD/tCH4. We find our base case estimate to be larger than the average SCM presented in other studies mainly due to the revised damage function we use. We also estimate the social cost of carbon (SCC) and find that SCM estimates are less sensitive to variations in the social discount rate than the SCC due to the relatively short lifetime of methane. Changes in the parameterization of the damage function have similar relative impacts on both SCM and SCC. Furthermore, we evaluate the ratio of SCM to SCC as an alternative metric to GWP-100 of CH4 to facilitate tradeoffs between these two gases. We find this ratio to lie in the range 7–33 in 2020, with a base case estimate of 21, based on an extensive sensitivity analysis with respect to the discount rate, damage cost, and underlying emission scenarios. We also show that the global warming potential (GWP) and the SCM to SCC ratio are almost the same if the inverse of the effective discounting (in the social cost calculations) is equal to the time horizon used to evaluate the GWP. For comparison, the most widely used GWP, i.e., with a time horizon of 100 years, equals 27, hence in the upper range of the ratio we find using the SCM to SCC ratio.

Climate economics support for the UN climate targets
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Under the UN Paris Agreement, countries committed to limiting global warming to well below 2 °C and to actively pursue a 1.5 °C limit. Yet, according to the 2018 Economics Nobel laureate William Nordhaus, these targets are economically suboptimal or unattainable and the world community should aim for 3.5 °C in 2100 instead. Here, we show that the UN climate targets may be optimal even in the Dynamic Integrated Climate–Economy (DICE) integrated assessment model, when appropriately updated. Changes to DICE include more accurate calibration of the carbon cycle and energy balance model, and updated climate damage estimates. To determine economically ‘optimal’ climate policy paths, we use the range of expert views on the ethics of intergenerational welfare. When updates from climate science and economics are considered jointly, we find that around three-quarters (or one-third) of expert views on intergenerational welfare translate into economically optimal climate policy paths that are consistent with the 2 °C (or 1.5 °C) target.
