On the coattails of the U.S. Environmental Protection Agency’s proposed rule for regulating carbon dioxide emissions from existing power plants, the White House issued a report on the health effects of climate change. The seven-page report outlines six major risks linked to rising temperatures—asthma, lung and heart illnesses; infectious disease; allergies; flooding-related hazards and heat stroke.
But one week after release of the EPA rule, most conversation centered on how the states will undertake their role in executing it. States in the Regional Greenhouse Gas Initiative were hopeful their participation in the carbon trading program would help meet the requirements of the new rule. Lawmakers in at least eight states approved anti-EPA resolutions. Kentucky has enacted a new law that could block the state from complying with the rule, and West Virginia sent a letter to the EPA requesting the agency to withdraw the rule.
The proposal, which assigns each state interim and final emissions goals and asks the states to develop plans to reach them, accounts for the regional differences that affect how hard it will be to reduce emissions. The differences are both practical—how expensive one energy source is compared to another—and political. The proposal does say it “anticipates—and supports—states’ commitments to a wide range of policy preferences,” including decisions “to feature significant reliance on coal-based generation.”
States using a more traditional regulatory approach to execute their plans may be choosing a more costly approach than putting a price on carbon. New research from the Massachusetts Institute of Technology finds that a regulatory standards approach cut less carbon at a higher price than emissions reductions that could be achieved under a cap-and-trade system (subscription).
“With a broader policy, like cap-and-trade, the market can distribute the costs across sectors, technologies and time horizons, and find the cheapest solutions,” said a study author Valerie Karplus. “So the market encourages emissions reductions from sectors like electricity and agriculture, and requires reductions from vehicles and electricity at a level that makes economic sense given an emissions target. On the other hand, narrow regulations force cuts in ways that are potentially more costly and less effective in reducing emissions.”
According to a Bloomberg national poll, Americans—by nearly a two-to-one margin—are willing to pay more for energy if it helps combat climate change. A recent Rasmussen Reports poll had similar findings, showing that most voters approve of the EPA’s new regulations even if there is a rise in energy costs. Here at the Nicholas Institute for Environmental Policy Solutions, we looked ahead to the possibility of a further expansion of Clean Air Act standards limiting carbon dioxide emissions from other sectors. In particular, a new policy brief identifies key differences between the electric power and refining industries, highlighting their potential significance for regulating the refining industry. A companion working paper more deeply examines policy design as well as options for maximizing cost effectiveness while accounting for differences among refineries.
Study: Agricultural Emissions Can Be Curbed
Worldwide, agriculture accounts for about 80 percent of human-caused emissions of nitrous oxide, a greenhouse gas with 300 times as much heat-trapping power as carbon dioxide. Overuse of nitrogen fertilizer is increasing these emissions.
A study in the journal Proceedings of the National Academy of Sciences found that soil microbes were converting nitrogen fertilizer (subscription) into nitrous oxide faster than previously expected when fertilizer rates exceeded crop needs. In fact, the change was happening at a rate of about one kilogram of greenhouse gas for every 100 kilograms of fertilizer.
“Our specific motivation is to learn where to best target agricultural efforts to slow global warming,” said Phil Robertson, author of the study and director of Michigan State University’s Kellogg Biological Station. “Agriculture accounts for 8 to 14 percent of all greenhouse gas production globally. We’re showing how farmers can help to reduce this number by applying nitrogen fertilizer more precisely.”
The study offers proven ways to reduce nitrogen use—applying fertilizer in the spring instead of fall and placing it deeper in the soil for easier plant access. It also provides support for expanding the use of carbon credits to pay farmers for improved fertilizer management.
This week, the first agricultural greenhouse gas emissions offsets were issued to a Michigan farmer whose voluntary decrease of nitrogen fertilizer use on corn crops reduced nitrous oxide emissions.
Crude Oil Production to Increase
U.S. crude oil production will reach its highest level—9.3 million barrels per day—in 2015, according to the latest Energy Information Administration (EIA) forecast, issued Tuesday. The EIA estimates 8.4 million barrels per day for 2014—the United States averaged 7.4 million in 2013.
The increase will not have a dramatic effect on gas prices. The EIA reports that the U.S. average price for gasoline is expected to fall to $3.54 a gallon in September and to $3.38 a gallon in 2015.

The U.S. Department of State has received a new application from TransCanada—the company behind the controversial Keystone XL project—to ship crude oil via a proposed pipeline running from the Canadian border to existing infrastructure in Nebraska. TransCanada had its initial application rejected by the Obama administration in January. The reapplication to the U.S. State Department on Friday calls to reroute the pipeline around the environmentally sensitive Sand Hills Region of Nebraska—adding miles onto the project. Despite the new route, some in Nebraska still oppose the plan. The pipeline is causing other problems as lawmakers debate a multi-year surface transportation plan—the first one since 2005.
If approved, construction on the pipeline could happen in early 2013, with oil flowing as soon as 2014, according to The Canadian Press.
That same day, the Obama administration issued a proposed rule requiring companies drilling for natural gas on federal and tribal lands to disclose chemicals used in hydraulic fracturing. While the rules also set standards for proper construction of wells and wastewater disposal, disclosure of the chemicals used in the “fracking” process would not have to be reported until after work is complete. The regulations, which could go into effect by the end of the year, spurred debate among environmentalists, industry and lawmakers—with some saying the rules didn’t go far enough. Others highlighted the “toughest” provisions, which require tests of wells’ physical integrity and expand the scope of water protected from drilling—but pointed out the rules “only apply to a sliver of the nation’s natural gas supply.”
Gas prices have continued a steady decline the last five weeks, causing the Energy Information Administration (EIA) to revise forecasts for the summer—predicting motorists will spend $10.7 billion less than previously estimated.
Heartland Institute Pulls Controversial Billboards
The Heartland Institute made headlines again recently for suggesting—in billboard ads—that only terrorists believe in manmade global warming. The failed campaign attacking the existence of climate change prompted a firestorm of criticism and recalled another kerfuffle involving the Institute earlier this year. Reactions to the campaign caused the Institute to announce removal of the billboards after being up just 24 hours. Even after they were removed, some donors pulled funding for the Heartland Institute, but others weren’t so quick to cut their ties with the organization.
A new study focuses blame for warming on another species entirely. It links methane emissions from dinosaurs, the sauropod specifically, to climate change and a warmer Mesozoic era. Like the dinosaurs before them, modern-day methane emitters such as cows and sheep are being studied to determine how the methane they emit could be contributing to warming. Regardless, according to the study, emissions from dinosaurs were far larger than those of our modern-day plant-eating animals, and in fact may have equaled all modern methane emissions—both natural and manmade.
New data sheds light on the speed of melting glaciers, and how their changes affect sea levels. Greenland’s ocean-bound glaciers accelerated by an average of 30 percent from 2000 to 2011—not quite as quickly had been estimated in previous worst-case scenarios, but still a cause for concern.
The Rise and Fall of Renewables
While a solar-powered boat was circumnavigating the world, on land the U.S. activated the first solar power project on federal land near Las Vegas. Meanwhile, residential solar leasing is taking off, Motley Fool reported. And in the next five years, the world’s solar power generating capacity is predicted to grow more than 200 percent, although public support for green energy initiatives has dropped recently.
Japan may be taking steps toward renewable energy after taking its last nuclear reactor off line last week. The move left the country without nuclear power for the first time since 1970. But MSNBC insisted renewables wouldn’t bring immediate relief, as only 10 percent of Japan’s power generation currently comes from renewables. Saudi Arabia is exploring whether it can generate a third of its electricity by way of solar power.
In the U.S., the renewable winner may not be necessarily who you think, according to the Washington Post. The EIA now has a map showing a large uptick in renewables between 2001 and 2011. This surge in renewables can largely be attributed to state renewable portfolio standards requiring utilities to obtain a certain percentage of their electricity from renewable sources, federal production tax credits and stimulus grants. The stimulus grants have expired; the tax credit for wind will expire at the end of 2012. The Guardian reports there is an effort underway by conservative think tanks in the U.S. to eliminate all government programs aimed at promoting the use of renewables.
