Report Says Global Carbon Dioxide Emissions on the Rise

The Nicholas Institute for Environmental Policy Solutions at Duke University

The International Energy Agency’s (IEA) first Global Energy and CO2 Status Report, released last week, had two major findings: preliminary estimates for 2017 suggest that global energy demand rose 2.1 percent—more than twice the previous year’s rate—and carbon dioxide emissions rose 1.4 percent, the first time they’ve increased in three years. Although emissions increased in most countries, they decreased in the United States and several other countries largely due to renewable energy deployments.

“The significant growth in global energy-related in 2017 tells us that current efforts to combat climate change are far from sufficient,” said IEA Executive Director Fatih Birol, who identified “a dramatic slowdown in the rate of improvement in global energy efficiency” as one of the causes.
That improvement in energy efficiency slowed from a rate of 2.3 percent a year over the last three years to 1.7 percent last year. Meanwhile, some 70 percent of 2017’s increased energy demand was met by fossil fuels. Emissions decreases in the United States, the U.K., Japan, and Mexico were insufficient to cancel out the increases in China and India.

According to the report, global energy-related carbon dioxide emissions reached a historical high of 32.5 gigatons in 2017, and current efforts to curb them are insufficient to meet Paris Agreement targets to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit it to 1.5 degrees Celsius.

“Global emissions need to peak soon and decline steeply to 2020; this decline will now need to be even greater given the increase in emissions in 2017,” the report says.

Some of the report’s other findings:

  • Oil demand grew by 1.6 percent, more than twice the average annual rate over the past decade, driven by the transport sector and rising petrochemical demand.
  • Natural gas consumption grew 3 percent, the most of all fossil fuels, driven by China and the building and industry sectors.
  • Coal demand rose 1 percent, reversing declines over the previous two years, driven by an increase in coal-fired electricity generation, mostly in Asia.
  • Renewables had the highest growth rate of any fuel, meeting a quarter of world energy demand growth.
  • Electricity generation increased by 3.1 percent, much faster than overall energy demand, with India and China accounting for most of the growth.
  • Fossil fuels accounted for 81 percent of total energy demand, continuing a three-decades-long trend.

Decision on Tailpipe Emissions Standards Expected

The U.S. Environmental Protection Agency (EPA) is up against an April 1 deadline to determine whether to loosen vehicle tailpipe emissions standards for the years 2022 to 2025, leave them unchanged, or increase them. Reports in the Wall Street Journal and other media outlets suggest the decision is likely to indicate that future vehicle emissions standards should be eased.

The rules, negotiated with the vehicle industry in 2011, presently require automakers to nearly double the average fuel economy of new cars and trucks to 54.5 miles per gallon by 2025.

“The draft determination has been sent to OMB [Office of Management and Budget] and is undergoing interagency review,” said Liz Bowman, an EPA spokeswoman. “A final determination will be signed by April 1, 2018, consistent with the original timeline.”

Unclear is how a decision to ease standards might affect California, which can set its own fuel standards and is authorized to do so under the Clean Air Act. The state has suggested it may withdraw from the nationwide program if the EPA eases regulations.

“California is not the arbiter of these issues,” said Scott Pruitt, EPA administrator, in an interview with Bloomberg. The state “shouldn’t and can’t dictate to the rest of the country what these levels are going to be.”

“We have not seen the document in question, and California had no input into its content,” said California Air Resources Board spokesman Stanley Young. “We feel strongly that weakening the program will waste fuel, increase emissions and cost consumers more money. It’s not in the interest of the public or the industry.”

EPA Holds Final Clean Power Plan Hearing

The U.S. Environmental Protection Agency (EPA) wrapped up public hearings concerning its repeal of the Clean Power Plan—an Obama-era regulation that sets state-by-state carbon emissions reduction targets for power plants—in Wyoming on Tuesday. All public comments on the proposed repeal of the Clean Power Plan are due April 26.

Dialogue in Tuesday’s hearing followed the trend of the EPA’s three other public hearings, with some arguing that the Clean Power Plan is needed to combat climate change and others questioning its effectiveness in achieving climate goals. One point of contention is how the costs and benefits of the rule were calculated. Opponents say the benefits were inflated and the costs were minimized. Supporters say the rule actually undercounts the additional benefits of reducing hazardous air pollutants.

The EPA was expected do away with the signature climate regulation, which the Supreme Court stayed in early 2016 and which would require the U.S. electricity sector to cut its carbon dioxide emissions by up to 32 percent from 2005 levels by 2030. But the Trump administration might consider a replacement at the urging of power companies fearful that a repeal could trigger courtroom challenges that would lead to years of regulatory uncertainty.

Any replacement rule may be affected by the EPA’s plans to propose measures to limit which studies the EPA can use in pollution rules—measures that could potentially reduce calculation of the health benefits that come along with controlling carbon dioxide emissions.

Study: Cutting Emissions Sooner Could Save 153 Million Lives This Century

The Nicholas Institute for Environmental Policy Solutions at Duke University

A new study suggests that premature deaths linked to air pollution would fall across the globe if nations agree to limit warming to 1.5 degrees Celsius above pre-industrial levels rather than postponing emissions cuts and allowing warming to reach 2 degrees Celsius. The research funded by the National Aeronautics and Space Administration (NASA), led by scientists at Duke University, and published in the journal Nature Climate Change finds that targeting the more ambitious of the Paris Agreement’s two temperature goals—although more costly—could avoid 153 million premature deaths.

“The lowest-cost approach only looks at how much it will cost to transform the energy sector,” said lead author Drew Shindell of Duke’s Nicholas School of the Environment. “It ignores the human cost of more than 150 million lost lives, or the fact that slashing emissions in the near term will reduce long-term climate risk and avoid the need to rely on future carbon dioxide removal. That’s a very risky strategy, like buying something on credit and assuming you’ll someday have a big enough income to pay it all back.”

The study is the first to project the number of lives that could be saved, city by city, in 154 of the world’s largest urban areas if nations agree to speed up the emissions reductions timetable and limit global temperature rise to 1.5 degrees Celsius. The greatest gains in saved lives would occur in Asia and Africa. India’s Kolkata stands to benefit most—seeing 4.4 million fewer early deaths by 2100 by cutting carbon pollution.

The researchers ran computer simulations of future emissions of carbon dioxide and associated pollutants such as ozone and particulate matter under three scenarios: accelerated emissions reductions and almost no negative emissions over the remainder of the 21st century, slightly higher emissions in the near term but enough overall reductions to limit atmospheric warming to 2 degrees Celsius by century’s end, and near-term emissions reductions consistent with a level that would limit atmospheric warming to 1.5 degrees Celsius. The researchers then calculated the human health impacts of pollution exposure under each scenario using well-established epidemiological models based on decades of public health data on air-pollution-related deaths.

Groups Press FERC to Revisit Energy Storage Decision

In February, the Federal Energy Regulatory Commission (FERC) unanimously approved rules to remove barriers to batteries and other storage resources in U.S. power markets, a potential game-changer for integration of renewables onto the grid. Monday, the Midcontinent Independent System Operator (MISO), the National Association of Regulatory Utility Commissioners (NARUC), and others filed separate requests asking FERC to reconsider this storage order. Some said that the proposal infringes on state authority.

“NARUC seeks clarification because the final rule specifies that states will not be allowed ‘to decide whether electric storage resources in their state that are located behind a retail meter or on the distribution system are permitted to participate in the [regional transmission organization/independent system operator] markets,’” the NARUC’s rehearing request said. “This statement should be deleted from the final rule.”

FERC oversees the regional transmission organizations (RTOs) and independent system operators (ISOs) that run wholesale electricity markets. In doing so, FERC establishes market rules that “properly recognize the physical and operational characteristics of electric storage resources” in its February decision after finding in November 2016 that existing market rules created barriers to entry for those resources. Under the rules, grid operators can use technologies such as batteries and flywheel systems to dispatch power, to set energy prices, and to offer capacity and ancillary services.

Although FERC’s rule directs regional grid operators to set a minimum size requirement for energy storage resources to participate in their markets that doesn’t exceed 100 kilowatts, it deferred issues about aggregations of smaller distributed energy resources to a technical conference in early April. MISO asked for clarification regarding the minimum size of storage for wholesale market participation, bid parameters, and a six-month extension on the order’s deadlines.

Pruitt May Release Measures to Restrict Science Used in Regulations

U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt may have plans to propose measures to limit exactly what data and studies the EPA can use in pollution rules. The idea would be to cease using scientific findings whose data and methodologies are not public or cannot be replicated.

Pruitt hinted at these intentions in a closed door meeting at the Heritage Foundation and in recent media interviews, saying “we need to make sure their [EPA] data and methodology are published as part of the record. Otherwise, it’s not transparent. It’s not objectively measured, and that’s important.”

Although formal plans have not been released, interviews indicate that Pruitt’s new rules would require EPA regulators to consider scientific studies that make the underlying data and methodology available to the public. The same rules would govern studies funded by the EPA. It is unclear whether the EPA would apply the directive to regulations now in place or only to new regulations. The former could affect several regulations at the EPA, including some wide-ranging air-quality regulations based on two studies from the 1990s that do not reveal their data.

Some critics, like Yogin Kothari of the Union of Concerned Scientists’ Center for Science and Democracy, say the move could undermine environmental laws. “It’s just another way to prevent the EPA from using independent science to enforce some of our bedrock environmental laws, like the Clean Air Act,” said Kothari.

Steve Milloy, who served on Trump’s EPA transition team and attended the meeting at the Heritage Foundation, said Pruitt’s plan could come “sooner rather than later.”

A similar proposal was passed in the U.S. House of Representatives in March 2017 as the Honest and Open New EPA Science Treatment (HONEST) Act, which would prohibit the use of “secret science” at the EPA. It’s since been referred to the Senate Environment and Public Works Committee.

Regional Grid Operators Weigh in on Resilience

The Nicholas Institute for Environmental Policy Solutions at Duke University

Regional grid operators filed comments on efforts to enhance the resilience of the bulk power system in a proceeding initiated by the Federal Energy Regulatory Commission (FERC) after rejecting a Notice of Proposed Rulemaking by U.S. Department of Energy (DOE) Secretary Rick Perry to subsidize coal and nuclear power plants. The comments by the nation’s federally overseen regional transmission organizations and independent system operators (ISOs) came in response to two dozen questions FERC asked about resilience.

The message of operators to FERC: allow them time to develop additional resilience measures and respect their existing efforts aimed at ensuring that grids can cope with man-made and natural disasters that pose a risk of electricity service disruption. None of the operators suggested that resilience requires preservation of uneconomical power plants. All appeared to be open to, in the words of the New York ISO, “additional dialogue regarding concepts for market-based resilience services and practices.”

Nevertheless, the PJM Interconnection filing departed from the other operator filings. In essence, PJM wants FERC to direct operators to update market compensation for power plants to reflect resilience attributes. The request comes amid concerns that PJM’s resilience filing and ongoing price reforms could basically have the same effect as the DOE subsidy proposal rejected by FERC in January—a proposal that would have benefited coal and nuclear generators.

Those concerns were echoed in a “joint statement on power market principles,” released last week by U.S. public power and rural electric co-ops, state utility advocates, wind and solar energy groups, the Natural Resources Defense Council and the American Council on Renewable Energy. The group asked FERC to apply technology-neutral and market-based solutions to the resilience docket.

The Perry proposal and the FERC proceeding it inspired are likely to lead to some kind of change. Last week at CERAWeek in Houston, FERC Chairman Kevin McIntyre said the lack of compensation to power plants for resilience contributions would be of concern to FERC and a particularly complicated element of the proceeding. He also said that “only hypothetically is nothing an option. I will be very surprised if we go through all that process and take no action.”

At the heart of that action could be how FERC defines resilience. In its filing, the California ISO questioned FERC’s working definition of resilience. It wrote that FERC’s reliance order “does not address any potential overlap between resilience and reliability, clearly articulate the differences between the two, state why a new, wholly separate concept is needed, or indicate what specific requirements a resilient system must meet.”

Two of my colleagues at Duke University’s Nicholas Institute for Environmental Policy Solutions made a similar point last month, noting that whether resilience is “a stand-alone concept or just a component of the well-recognized concept of reliability” is a “foundational question”—one that spells the difference between new market and regulatory responses or tweaks to existing reliability mechanisms. They conclude that “A well-functioning market that clearly defines and values the attributes needed for grid reliability and resilience—in a fuel-neutral, technology-neutral fashion—will comply with the law and support both concepts.”

China Unveils Environmental Restructuring Plan

A draft plan, introduced Tuesday, reorganizes China’s government into a State Council composed of 26 ministries and commissions. Compared with the current setup, the number of ministerial-level entities is reduced by eight and that of vice-ministerial-level entities by seven.

One of the changes is renaming the Ministry of Environmental Protection. The new Ministry of Ecological Environment would take over responsibility for climate change policy and become the only entity in charge of policies related to climate change, water resource management, and pollution.

“China’s decision to create a new environment ministry in China, which includes the country’s climate change agenda, is a big shake up in the country but may well be a positive long-term development,” said Jackson Ewing, senior fellow at Duke University’s Nicholas Institute for Environmental Policy Solutions and adjunct associate professor at the Sanford School of Public Policy. “Although the practical impacts of China’s reorganization are not yet apparent, the Ministry for Ecological Environment appears poised to carry a strong mandate to strengthen the country’s air, water, soil and ecological focus.”

Tonny Xie, director of the Secretariat for the Clean Air Alliance of China noted that the change is “ … also a sign that China will continue the unprecedented commitment and investment to improve environmental quality in future, which will generate significant market potential for clean technologies.”

The plan, submitted by the government to parliament is expected to be approved this weekend after deliberations by the National People’s Congress, China’s parliament.

China, the world’s largest polluter, is in the midst of launching a nationwide emissions trading system to set emissions quotas for companies in the power sector. Announced in December, the program could more than double the volume of worldwide carbon dioxide emissions covered by tax or tradable permit policy.

Trump Fires Tillerson, Nominates New Secretary of State

President Donald Trump on Tuesday announced the exit of Secretary of State Rex Tillerson and the nomination of Mike Pompeo, the present director of the CIA, to replace him.

“Rex and I have been talking about this for a long time. We got along actually quite well, but we disagreed on things,” Trump said. “When you look at the Iran deal, I think it’s terrible, I guess he thought it was OK … So we were not really thinking the same. With Mike Pompeo, we have a very similar thought process. I think it’s going to go very well.”

Tillerson stood as a lonely voice in the Trump administration urging the president not to withdraw from the Paris Agreement, a global treaty that aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. But Trump announced last year that the United States would be the only nation in the world not party to the agreement, though it cannot formally withdraw until 2020.

As a former Congressman, Pompeo described the new 2015 Paris Agreement as a “costly burden” to the United States. He noted then that “Congress must also do all in our power to fight against this damaging climate change proposal and pursue policies that support American energy, create new jobs and power our economy.”

Pompeo will appear before the Senate Foreign Relations Committee for his confirmation hearing in April, but his path to confirmation is uncertain.

Some Say Planned Steel, Aluminum Tariffs May Add Up to Losses for U.S. Energy

The Nicholas Institute for Environmental Policy Solutions at Duke University

On Monday, President Donald Trump said “we’re not backing down” on his intent to propose steel and aluminum tariffs that some legislators and analysts worry could have a negative effect on the U.S. energy industry and undercut the president’s goal of “energy dominance.”

Trump shared his desire for the tariffs—25 percent on steel imports and 10 percent on aluminum imports—last week. On Wednesday, White House press secretary Sarah Huckabee Sanders said that countries may be exempted on a “case-by-case basis” from the tariffs and that the president will make an announcement on the tariff issue by the week’s end.

Energy industry groups say that the plan to put a 25 percent tariff on overseas steel could a have a detrimental impact on the U.S. oil and gas industry and could be a double blow for the solar power industry, which is navigating new solar tariffs that went into effect last month. The groups contend that the steel tariff would raise costs for oil and gas pipelines and for solar power arrays, which would also face increased costs from Trump’s anticipated tariff on aluminum imports.

The 25 percent steel tariff could add as much as 2 cents a watt to the cost of a utility-scale solar project, according to the Solar Energy Industries Association. Additional price increases on steel and on aluminum, which are used in ground-mount and rooftop solar racking systems, could slow U.S. solar deployments already decreased by the solar tariff.

In the oil and gas industry, the 25 percent steel tariff could have an impact on pipelines. A study commissioned by oil and gas groups and released last year showed that a 25 percent price hike means an additional $76 million in costs for a traditional 280-mile pipeline and more than $300 million for a major project like the Keystone XL or Dakota Access pipelines.

Rules Governing Pollution from Oil and Gas Operations Under Microscope

The U.S. Environmental Protection Agency (EPA) announced amendments to two provisions of the New Source Performance Standards for the oil and natural gas industry. The 2016 standards aim to reduce the amount of methane and volatile organic compounds from oil and gas drilling.

One of EPA’s amendments would require that oil and gas operators repair leaking components during unplanned or emergency shutdowns and would impose monitoring requirements for wells on Alaska’s North Slope.

EPA said the changes were necessary because under the current requirements, repairs conducted during unscheduled or emergency shutdowns “could lead to unintended negative consequences both at well sites and compressor stations, including emissions that are higher than emissions that would occur if the leaks were repaired during a scheduled shutdown.”

The changes “provide regulatory certainty to one of the largest sectors of the American economy and avoid unnecessary compliance costs to both covered entities and the states,” said EPA Assistant Administrator for Air and Radiation Bill Wehrum, noting that the amendments are expected to save electric utilities $100 million per year in compliance costs and that they could help oil and gas operators reap $16 million in benefits by 2035.

Environmental advocates, meanwhile, expressed concerns that the changes could lead to dirtier air and water and reduce or remove consequences for large-scale polluters.

As Bloomberg Gets UN Climate Envoy Job, Study Pushes Emissions Trading

Former New York Mayor Michael Bloomberg was named U.N. special envoy for climate action on Monday. In his new role, Bloomberg will support a 2019 U.N. Climate Summit and mobilize more ambitious action to implement the 2015 Paris Agreement, which aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius.

“Around the world, bottom-up solutions are leading the fight against climate change,” Bloomberg said in a Twitter post. “As the new @UN Special Envoy for Climate Action, I’ll work with state and non-state actors to help implement policies that reduce emissions & build resilience.”

Three researchers wrote in the journal Science that allowing countries to satisfy their climate commitments by trading credits could bring down implementation costs.

“Linkage is important, in part, because it can reduce the costs of achieving a given emissions-reduction objective,” the authors write. “Lower costs, in turn, may contribute politically to embracing more ambitious objectives. In a world where the marginal cost of abatement (that is, the cost to reduce an additional ton of emissions) varies widely, linkage improves overall cost-effectiveness by allowing jurisdictions to finance reductions in other jurisdictions with relatively lower costs while allowing the former jurisdictions to count the emission reductions toward targets set in their NDCs [nationally determined contributions].”

Tax Credit Could Help Increase Carbon Capture and Storage, Some Say

The Nicholas Institute for Environmental Policy Solutions at Duke University

As part of the Bipartisan Budget Act of 2018, Congress gave a boost to carbon capture—a method for diverting emissions from crude production and coal- and gas-fired power plants—through the so-called 45Q tax credit. For every qualifying project, the boosted 45Q doubles a pre-existing tax credit to $50 per ton of carbon dioxide buried in underground storage and to $35 per ton that is used in a consumer product or to stimulate oil recovery.

“The act also expands the ‘EOR’ [enhanced oil recovery] credit to carbon oxides used for other industrial purposes, changes the definition of the entities to whom the credit applies, and sets capture thresholds for small facilities, electric generating facilities, and direct air capture facilities,” write Frederick R. Eames and David S. Lowman Jr. in Lexology.

Many see the potential for this credit to spur a renewed look at projects with carbon capture and storage and re-enliven policies around it.

“Now, with [the tax credit], the economics are looking very attractive,” said Roger Ballentine, a consultant and board member of 8 Rivers Capital, which is financing NET Power, a carbon capture project near Houston. “People are asking, should I do this. Before, those conversations weren’t even happening. Any major project like this will be a challenge. But the business case gets that much better with [the tax credit]. Once there is a business case, that’s why they happen.”

The nudge from the tax credit could help the technology to be more profitable.

“The reality of any technology development, particularly in the energy space, is it’s very difficult to move technologies into the marketplace without some sort of push,” said Walker Dimmig, spokesperson for NET Power. “The energy marketplace is incredibly competitive.”

Court Orders Enforcement of Methane Leak Rule

Last week, U.S. District Judge William Orrick issued a preliminary injunction blocking the Trump administration’s attempt to delay an Obama-era Bureau of Land Management (BLM) rule that sought to reduce venting, flaring and leakage of methane gas on public and tribal lands. The U.S. District Court for the Northern District of California ruled that BLM did not justify its decision to delay core provisions of its 2016 Methane and Waste Prevention Rule by one year.

“The BLM’s reasoning behind the Suspension Rule is untethered to evidence contradicting the reasons for implementing the Waste Prevention Rule, and so plaintiffs are likely to prevail on the merits,” Orrick wrote. “They have shown irreparable injury caused by the waste of publicly owned natural gas, increased air pollution and associated health impacts, and exacerbated climate impacts.”

In the lawsuit brought by environmental groups and two states—California and New Mexico—Orrick also denied a request to move the case to Wyoming where a similar case is pending.

The ruling was only on the BLM’s proposed one-year delay. It does not directly affect the BLM’s proposed repeal of several methane rule provisions announced earlier this month. That proposal removes at least seven elements introduced under Obama’s rule, including creation of waste minimization plans by companies and emissions reduction standards for well completion.

In announcing the changes to that portion of the rule, the BLM said that many of the former requirements were duplicative of state laws or had a higher cost or lower benefit than previously estimated. Once the BLM proposed repeal is published in the Federal Register, a 60-day public comment period will begin.

Reports Indicate Growth in Renewables in Cities

Worldwide, 101 cities are getting at least 70 percent of their total electricity supply from renewable energy—more than double the number since the 2015 signing of the Paris Agreement according to the Carbon Disclosure Project, which tracks climate-related commitments by corporations and governments.

The London-based Carbon Disclosure Project attributes the increase to the growing number of cities reporting to it (currently 570) and to a global shift to renewable energy. It reports that cities are investing $2.3 billion in 150 clean energy development projects and $52 billion in low-carbon urban infrastructure projects such as energy efficiency upgrades, electric transport networks and smart city programs.

“Cities are responsible for 70 percent of energy-related CO2 [carbon dioxide] emissions and there is immense potential for them to lead on building a sustainable economy,” said Kyra Appleby, director of cities at the Carbon Disclosure Project.

Notably, more than 40 of the cities identified in the report are powered entirely by renewables, including Burlington, Vermont, which gets its electricity from wind, solar, hydro and biomass. Although only a few of the 100-plus U.S. cities that report their energy mix to the project have achieved 70 percent or greater renewables generation, another 58 U.S. cities, including Atlanta and San Diego, are planning to hit the 100 percent renewables target within 20 years.

Meanwhile, two new studies shed light on renewables potential and actual deployment in the United States.

In one, scientists at the University of California at Irvine, the California Institute of Technology, and the Carnegie Institution for Science revealed that the country could reliably meet about 80 percent of its electricity demand with solar and wind power generation “by building either a continental-scale transmission network or facilities that could store 12 hours’ worth of the nation’s electricity demand.” Both options would entail huge—but not inconceivable—investments, they said.

A study by Southern Alliance for Clean Energy revealed that solar deployment is growing in some southern states, including North Carolina, where the solar market, one of the nation’s largest, is driven by favorable implementation of federal laws requiring renewable energy procurement, a state tax credit, and a renewable energy mandate. South Carolina, Florida, and Georgia are also emerging as significant state markets.

Globally, falling costs are playing a role in renewables uptake. According to data released by the World Economic Forum, unsubsidized renewables were the cheapest source of electricity in 30 countries in 2017, and they are expected to be consistently more cost effective than fossil fuels globally by 2020.
