Good day, Clean Power Programme: Stanford researchers talk over the new energy dominion

The U.S. Ecology Protection Agency replaced the Obama-era Clean Power Program this week with one that focuses on efficiency improvements at generating stations. Stanford experts on law, energy policy and economics discuss the move and its potential impacts.

On June 19, the U.Southward. Environmental Protection Agency (EPA) put the final nail in the coffin of the Obama administration's signature environmental policy.

The EPA'due south newly released Affordable Clean Energy (ACE) rule replaces the Make clean Ability Plan (CPP), which was intended to reduce greenhouse gas emissions from the power sector by 32 percent in 2030 compared to 2005 levels. The program, which went into effect but was almost immediately put on hold by the courts, would accept allowed states to meet those goals through a variety of means, including switching from burning coal to natural gas, which produces significantly less greenhouse gases, or increasing renewable energy sources. Information technology would also have fabricated it difficult to build new coal-fired power plants. By contrast, the new rule aims to reduce power plant carbon emissions without actually setting limits on them. Instead, the rule calls for efficiency improvements at generating stations and directs states to take the initiative on how they choose to regulate ability plant emissions.

Supporters applaud the dominion's flexibility, empowerment of states and legal defensibility. Critics say the alter will lead to higher emissions, damage the health of people and the environment and slow the transition to a clean-energy economic system.

Stanford News Service spoke with economist Charles Kolstad, legal scholar Deborah Sivas and energy and climate policy expert Michael Wara about the new rule and its potential impacts.

Is there annihilation surprising virtually the revised plan?

Sivas: I idea the Trump administration might just suspend the Clean Power Plan and delay doing anything else at all. Simply I'm certain lawyers for the assistants have figured out that under the Clean Air Act and court precedents, EPA actually must take activeness to abate greenhouse gas emissions. So, rather than ignore the police entirely, the administration has promulgated a final, much weaker rule.

Kolstad: I am struck that EPA'southward previous approach – supercede the CPP with the ACE – has been scrapped, due to logical flaws in their arguments, I presume, in favor of a two-stride approach. Starting time, declare the CPP as having no effect on emissions as well as having other flaws and then repealing it. Secondly, show that the ACE is a cost-do good improvement on the new status quo of no CPP – impressive. Information technology'southward a sleight of manus.

Wara: I recall the almost of import aspects of this rule take to practise with how the benefits of reduced air pollution are treated. The Trump EPA has – from the commencement – emphasized the dubiousness of benefits associated with reducing emissions of particulates and ozone. They continue this approach under the final ACE rule. This is likely to have knock-on furnishings for future air pollution regulations, and will be a precedent that is hard to disengage fifty-fifty if a future assistants wants to count these benefits. That will make farther reductions in ozone and particulate affair harder to achieve.

What does this mean for coal ability in the U.S.? What is the industry's prognosis?

Kolstad: The main problems with coal power in the U.Due south. are cheap natural gas and risks associated with investing in it. Neither CPP nor the ACE are critical to the industry's outlook. Information technology is interesting to annotation that the Dow Jones index of coal stocks had dropped about 10 percent from when Donald Trump took over. The introduction of the ACE acquired the index to rise about vii per centum – a small sign of the extent to which markets call back the ACE will help the U.S. coal industry. My sense is that the ACE will accept very little touch on on the continuing decline of coal-fired electricity production over the coming decade.

Wara: The ACE rule forthrightly acknowledges that coal power is struggling economically in the U.South. Indeed, the dominion points out that the Obama Make clean Ability Plan targets are set up to be achieved ahead of time and without any regulation. Unless in that location is a dramatic change in the price of natural gas, coal-fired electricity is likely to proceed to decline in importance while natural gas and renewable energy volition increment as sources of power.

Sivas: A flurry of lawsuits past states and conservation groups will probably offset soon and continue well beyond the 2020 election. That likely means that for the side by side few years, today's rule volition have little on-the-ground touch. Given the legal uncertainty, at that place is a substantial question of how the power sector will answer in the short term to market risks. But if today'southward rule is upheld past the courts and if Trump is reelected, the overall result of EPA's activeness could be some extension of the life of coal-fired plants. Information technology all depends on how markets reply to the legal and political uncertainty.

Is focusing solely on improving the efficiency of facilities sufficient to tackle the problem?

Wara: No. Merely the Trump assistants has taken the position that efficiency improvements are all that the legal authority provided by the Clean Air Deed will permit. Heat rate improvements at coal- and gas-fired power plants will merely become so far. Ultimately, we demand to supplant coal and gas-fired power plants with nil-carbon resources if we are to have whatsoever hope of avoiding unsafe climate alter.

Sivas: Increased efficiency is a skillful thing, of class, because it reduces the pollution generated for each unit of energy produced. Information technology remains to be seen whether the power industry will conclude that it is cost-effective to retrofit existing coal or other natural gas plants for increased efficiency – as opposed to looking toward renewable energy or options that permit consumers to reduce or shift their electricity usage in response to financial incentives. The problem from a climate perspective is that EPA's focus on retrofitting existing coal plants entirely ignores that switching to cleaner energy sources and demand-response policies is, in fact, the all-time fashion to reduce emissions. Energy efficiency improvement alone will never bend the greenhouse gas emissions curve the way we need to.

If in that location are no caps on emissions, what incentives are there for states to control emissions?

Kolstad: None from the feds, except for generating efficiency improvements. But states have many other reasons for wanting to reduce carbon emissions. Carbon emissions are clearly in the crosshairs. Maybe not for this federal administration but quite possibly the next. Financial markets consider carbon emissions a financial risk, and the populations of many states, such as California, Oregon and Washington, want to clean upward their human activity.

Wara: Nether ACE, states have to ensure that ability plants within their borders meet efficiency requirements. These are essentially rate-based standards set up at the power institute level. Under the Clean Power Plan, by contrast, states had to attain a statewide standard. Given the evolution of the power system due to low natural gas prices, neither dominion would create strong incentives for states to command emissions.

What was the basis of the analysis that undergirds the new rule?

Sivas: In the proposed rule, EPA was able to reach a different result than the Clean Power Plan through various sleights-of-hand. For instance, the EPA has changed how information technology calculates the social price of carbon. The rule also ignores the incidental public wellness benefits – beyond reduced greenhouse gas emissions – associated with reduced power plant pollution. In certain ways, the rule narrowly reinterprets EPA's authority under the Clean Air Act. All of these changes, collectively, allowed EPA to significantly weaken the dominion equally compared to the Clean Power Plan and withal claim it is in compliance with the Clean Air Human action.

What do you lot brand of EPA estimates that the new rule, when fully implemented, will lead to a 10-million-ton reduction in carbon dioxide (CO₂) emissions and will provide annual net benefits of $70 one thousand thousand to $100 million or more?

Kolstad: A reduction of 10 million tons is nice, but it is near a one-half a percent of current power sector emissions. The benefits are probably understated since the Trump administration controversially cutting the social toll of carbon past about an order of magnitude, compared to the Obama administration's $40 per ton for damages from CO₂.

Sivas: The Clean Ability Plan projected emission reductions at full implementation of 870 million tons. So if that is an apples-to-apples comparison, it pretty much says it all. With respect to the monetary benefits, it all depends on how one calculates the social cost of carbon and whether non-GHG [greenhouse gas] emissions reductions are factored into the "benefits" calculation – things like reduced particulate emissions that accept serious morbidity and bloodshed effects. Playing with those benefits assumptions, every bit EPA did here, pretty much renders the resulting numbers meaningless.

Is information technology true, equally EPA Administrator Andrew Wheeler has said, that the new dominion is more legally defensible than CPP was?

Wara: The Clean Ability Program utilized a novel interpretation of the Clean Air Act to allow for more than stringent regulation of polluting sources. The ACE sticks to the traditional estimation of the New Source Functioning Standards section of the act. So it does accept less legal hazard in that sense. However, various aspects of the rule'south arroyo to quantification of benefits and costs volition no doubt exist challenged in court, perhaps successfully. Both rules were radical, albeit in different means. I think there's a decent gamble of this regulation failing to pass muster earlier the courts.

Sivas: The courts volition ultimately decide, I approximate. Wheeler's statement turns largely on the Trump administration and power industry argument that the Clean Power Plan illegally considered "best system for emission reduction" under the Clean Air Deed to include such "beyond the fenceline" options as fuel switching and need response. Indeed, the only way that the current EPA arrived at free energy efficiency as the best organization for emission reduction was by saying that any action across retrofitting of the existing power constitute itself could not exist considered in setting standards and developing the rule. Wheeler'southward new interpretation of the law is definitely much narrower than the pre-2016 estimation, but that doesn't necessarily mean it is more legally defensible. EPA's regulations implementing this provision of the Clean Air Act have historically allowed for practices like emissions trading schemes to see standards. It is hard to judge what the courts might do with all of these circuitous, interwoven pieces.
