Canada has adopted the US approach to calculating the SCC, but also recently agreed a national price of C$10/tCO2 ($8), rising to C$50 in 2022 ($38 at current exchange rates). It’s one way to put a price on CO2 emissions – but the Trump administration may try to amend it. A 2015 survey of 200 general economists found that most preferred a rate between 1% and 3%.

Guest post: How climate change is turning glaciers into lakes, Guest post: How public attitudes towards ‘CO2 removal’ differ in the UK and US. Each of the four elements in the models is uncertain and incomplete. This does not apply to the US. They are predominantly based on literature from the 1990s and early 2000s, since which time the science has evolved substantially.

In response to this criticism, the US Court of Appeals has said that “global effects are an appropriate consideration when looking at a national policy.” It’s worth asking what would happen if the the US were to ignore global effects. Rather than what the temperature would be once the climate system balances out completely, there is a simpler metric known as the Transient Climate Response (TCR). [18] Calculating the SCC brings about a degree of uncertainty particularly due to unknown future economic growth and development as well as pending climate system response. The SCC in the latest version of DICE (DICE-2016) has a considerably higher SCC than previous incarnations.
There is obviously also an ethical argument to be made. The year following in 2009 there was a call for a uniform calculation of social cost from carbon to be utilized by the government. Under the heading, “Ending the use of the social cost of carbon in federal rulemakings”, it says: “The Obama administration aggressively used the social cost of carbon (SCC) to help justify their regulations. The EU has also moved away from policy appraisal based on the SCC towards a target-consistent approach. The social cost of carbon (SCC) is the marginal cost of the impacts caused by emitting one extra tonne of greenhouse gas (carbon dioxide equivalent) at any point in time, inclusive of 'non-market' impacts on the environment and human health. One alternative is to choose a temperature limit first, drawing together scientific and economic evidence along with political and ethical considerations. Climate change is a classic market failure. Economists approach this question using discounting. Third is benefits and damages: How will climate change affect crop yields? In attacking the standards, it suggested that the DOE had been “arbitrary and capricious” in even using the SCC, that the calculations used to come up with the SCC were “irredeemably flawed”, that the analysis overestimated the benefits and underestimated the costs of cutting carbon, and that it was wrong to consider the global, rather than national, impacts of climate change. “He can’t get rid of the court decision…You can’t get around the need to have a cost-benefit analysis,” Denise Grab, a senior attorney at the Institute for Policy Integrity, told Carbon Brief. [1] The purpose of putting a price on a ton of emitted CO2 is to aid policymakers or other legislators in evaluating whether a policy designed to curb climate change is justified. As such, some models only partially account of climate impacts that scientists think can, in turn, raise or lower emissions, known as “feedbacks“. US government guidance is to use discount rates of both 3% and 7% for valuing costs and benefits within a single generation of, say, 30 years.

All Rights Reserved. This hedges their investments if a CO2 tax were to be adopted. The DICE model defines the SCC to be "equal to the economic impact of a unit of emissions in terms of t-period consumption as a numéraire". In a major survey of 197 economists, the average long-term discount rate was 2.25%. This value can then be used to weigh the benefits of reduced warming against the costs of cutting emissions. [11], Recent large studies estimate the social cost of carbon as high as $417 tCO2[12] or as low as $54 tCO2. )", "Expert Consensus on the Economics of Climate Change", "The IPCC Report is a Wake Up Call for Scholars, Advocates, and Philanthropists", "Why do carbon dioxide emissions weigh more than the original fuel? The SCC was bred from both the executive orders demanding the integration of cost-benefit analysis in new regulations and the CBD lawsuit, which established that such analysis could not ignore CO2 emissions. The SCC puts the effects of climate change into economic terms to help policymakers and other decisionmakers understand the economic impacts of decisions that would increase or decrease emissions. In 2009, it was Barack Obama who ordered a uniform US social cost of carbon be drawn up for the first time, but, indirectly, Americans also have Ronald Reagan, Bill Clinton and George W Bush to thank for the measure. The effects of climate change will be felt over many hundreds of years, whereas cutting emissions costs money now. Carbon Brief has also produced a timeline, above, showing the key dates in the scientific, regulatory and legal history of the social cost of carbon. In its latest report, the Intergovernmental Panel on Climate Change (IPCC) put the likely value for ECS in the range 1.5-4.5C. A questionnaire sent by Trump’s transition team, which they later disavowed, to the Department of Energy asked: “Can you provide a list of all Department of Energy employees or contractors who have attended any Interagency Working Group on Social Cost of Carbon meetings? What are PAGE, DICE, FUND, and how do they differ? “There are regulations in place using that number and they can’t be undone with the stroke of a pen,” adds Grab. According to a search of the government Federal Register, the SCC is currently a factor in 69 final rules and a further 80 proposed rules.
Everything you ever needed to know about the Social Cost of Carbon, Published by Carbon Brief Ltd - Company No. But the IAMs used by the US government to calculate SCC aren’t generally considered fully up to date in terms of the latest science. This means that IAMs’ assumptions and equations for GDP growth are important, too.
Far bigger influences come from how the models represent the climate system, the expected costs for a given temperature rise and the discount rate. In this detailed Q&A, Carbon Brief looks at the basics, the science and the politics of the social cost of carbon, as well as the legal situation in the US.

For policy appraisal, it found countries including Chile, Canada, the US, France, the UK and Germany using an average 2014 price of $56/tCO2, rising to $115 in 2050.
