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.
