EPA Refuses to Control Pollution from Ships, Aircraft and Non-Road Engines
The U.S. Environmental Protection Agency (EPA) announced that it would not take action to control global warming pollution from major mobile sources at this time. The agency’s decision not to regulate ships and other non-road engines, and its indefinite delay in regulating aircraft, comes in response to a 2010 lawsuit from an environmental coalition asking the EPA to address these types of pollution. The announcement, which presents a major setback to efforts to curb global warming emissions, came despite a recent court ruling that the EPA has a duty to address greenhouse pollution from aircraft.
Together, aircraft, ships and non-road vehicles and engines are responsible for 24 percent of U.S. mobile source greenhouse gas emissions and emit approximately 290,000 tons of soot every year. Pollution from these sources is projected to grow rapidly in the coming decades.
The coalition petitioned the EPA in late 2007 and early 2008 to determine whether greenhouse gas emissions from marine vessels, aircraft and non-road vehicles and engines respectively endanger public health and welfare and, if so, to issue regulations to control greenhouse gas emissions from these sources. In 2009 the EPA found that greenhouse gas emissions from cars do harm human health but the agency has yet to take action to control these same emissions from non-road sources.
“The shipping industry is a major contributor to global warming pollution, but it’s also one of the few sectors where climate solutions will actually save companies money. Annually U.S. ships release more carbon dioxide than 130 million cars and this is on track to triple over the next 20 years. It is time for EPA to issue common sense rules—like setting fuel efficient speed limits—to control pollution from this important sector, especially since it would be a ‘win-win’ proposition,” said Jackie Savitz, vice president for North American Oceans at Oceana.
“Now is the time for EPA to turn to these sources of pollution,” said Sarah Burt of Earthjustice, representing the coalition. “EPA has a clear moral obligation and legal duty under the Clean Air Act to act decisively to protect public health and the environment on which all Americans depend.”
“The Clean Air Act successfully reduces dangerous air pollution and saves lives,” said Kassie Siegel, director of Center for Biological Diversity’s Climate Law Institute. “Cost-effective solutions to reduce greenhouse emissions from ships, airplanes and non-road engines are available now. The Obama administration’s decision to shelve these common-sense pollution-reduction measures is tragic and absurd.”
“The evidence of climate change is becoming clearer each and every day,” said Marcie Keever, oceans and vessels project director for Friends of the Earth. “We can no longer afford the EPA’s refusal to address important and growing sources of greenhouse gas emissions.”
“EPA needs to shift into high gear and limit the impact that industrial non-road vehicles and engines impose on our common airshed,” said Dan Galpern, an environmental attorney representing the International Center of Technology Assessment, the Center for Food Safety and Friends of the Earth on the non-road petition. “The climate crisis will not be allayed without the maximum achievable reduction in GHG emissions. This requires reasonable restrictions on monster earth movers, heavy mining and logging equipment, agricultural pumps and other industrial machinery that presently spew climate pollution without end.”
The lawsuit at issue on June 19 was filed in federal district court in the District of Columbia by Earthjustice and the Western Environmental Law Center on behalf of Oceana, Friends of the Earth, the Center for Biological Diversity, the Center for Food Safety and the International Center for Technology Assessment.
Independent U.S. scientists, having evaluated the paleoclimate and instrumental records, as well as increasingly sophisticated geophysical models, have determined with high confidence that global warming caused by greenhouse gas emissions from the burning of fossils fuel has begun to disrupt global and regional climate systems. They predict that, unless these emissions are reduced sharply within decades, natural and human systems on which species and civilization respectively depend will be disrupted irretrievably. In partial response, the U.S. EPA has begun to restrict such emissions from new cars and light trucks, but the government’s determination to act strongly to preserve a habitable climate system remains in question. Major sector sources of GHG emissions, including aircraft, vessels and other non-road vehicles and engines, must not be given a free ride.
Aviation and global warming
Aircraft emit 11 percent of carbon dioxide emissions from U.S. transportation sources and 3 percent of the United States’ total greenhouse gas emissions. The U.S. is responsible for nearly half of worldwide CO2 emissions from aircraft, and such emissions from aircraft are anticipated to increase substantially in the coming decades due to the projected growth in air transport. According to the Federal Aviation Administration, emissions from domestic aircraft will increase 60 percent by 2025. While some countries, such as the European Union, have already begun to respond to these challenges, the U.S. has failed to address this enormous pollution source.
Ships and global warming
In 2008 marine vessels entering U.S. ports accounted for 4.5 percent of domestic mobile source greenhouse gas emissions. The global fleet of marine vessels releases almost 3 percent of the world’s CO2, an amount comparable to the total greenhouse gas emissions of Canada. Because of their huge numbers and inefficient operating practices, marine vessels release a large volume of carbon dioxide, nitrous oxide and black carbon, or soot. If fuel use remains unchanged, shipping pollution will potentially double from 2002 levels by the year 2020 and triple by 2030. Despite their impact on the global climate, greenhouse gas emissions from ships are not currently regulated by the U.S. or the international community.
Non-road vehicles and engines and global warming
Non-road vehicles and engines are used in the agricultural, construction, commercial, industrial, mining and logging sectors. In 2008 such industrial non-road vehicles and engines were responsible for approximately 9 percent of U.S. mobile source CO2 emissions, as well as significant emissions of black carbon, or soot. Nearly one-third of these emissions are produced by the construction and mining sectors, while one-fifth are from agriculture. The EPA projects that CO2 emissions from the non-road sector will increase approximately 46 percent between 2006 and 2030.

Natural gas is a versatile fossil fuel that accounts for about a third of U.S. energy use. Although it produces fewer greenhouse gas emissions and other pollutants than coal or oil, natural gas is a major contributor to climate change, an urgent global problem. Reducing emissions from the natural gas system is especially challenging because natural gas is used roughly equally for electricity, heating, and industrial applications.

What RNG Is and Why it Matters<p>Most equipment that uses energy can only use a single kind of fuel, but the fuel might come from different resources. For example, you can't charge your computer with gasoline, but it can run on electricity generated from coal, natural gas or solar power.</p><p>Natural gas is almost pure methane, <a href="https://www.eia.gov/energyexplained/natural-gas/" target="_blank">currently sourced</a> from raw, fossil natural gas produced from <a href="https://www.eia.gov/energyexplained/natural-gas/where-our-natural-gas-comes-from.php" target="_blank">deposits deep underground</a>. But methane could come from renewable resources, too.</p><p><span></span>Two main methane sources could be used to make RNG. First is <a href="https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks" target="_blank">biogenic methane</a>, produced by bacteria that digest organic materials in manure, landfills and wastewater. Wastewater treatment plants, landfills and dairy farms have captured and used biogenic methane as an energy resource for <a href="http://emilygrubert.org/wp-content/uploads/2019/02/eia_860_2017_map.html" target="_blank">decades</a>, in a form usually called <a href="https://www.eia.gov/energyexplained/biomass/landfill-gas-and-biogas.php" target="_blank">biogas</a>.</p><p>Some biogenic methane is generated naturally when organic materials break down without oxygen. Burning it for energy can be beneficial for the climate if doing so prevents methane from escaping to the atmosphere.</p>
Renewable Isn’t Always Sustainable<p>If RNG could be a renewable replacement for fossil natural gas, why not move ahead? Consumers have shown that they are <a href="https://www.nrel.gov/analysis/green-power.html" target="_blank">willing to buy renewable electricity</a>, so we might expect similar enthusiasm for RNG.</p><p>The key issue is that methane isn't just a fuel – it's also a <a href="https://www.eia.gov/environment/emissions/ghg_report/ghg_overview.php" target="_blank">potent greenhouse gas</a> that contributes to climate change. Any methane that is manufactured intentionally, whether from biogenic or other sources, will contribute to climate change if it enters the atmosphere.</p><p>And <a href="http://doi.org/10.1126/science.aar7204" target="_blank">releases</a> <a href="https://doi.org/10.1016/j.wasman.2019.07.029" target="_blank">will happen</a>, from newly built production systems and <a href="https://theconversation.com/why-methane-emissions-matter-to-climate-change-5-questions-answered-122684" target="_blank">existing, leaky transportation and user infrastructure</a>. For example, the moment you smell gas before the pilot light on a stove lights the ring? That's methane leakage, and it contributes to climate change.</p><p>To be clear, RNG is almost certainly better for the climate than fossil natural gas because byproducts of burning RNG won't contribute to climate change. But doing somewhat better than existing systems is no longer enough to respond to the <a href="https://doi.org/10.1038/nclimate2923" target="_blank">urgency</a> of climate change. The world's <a href="https://www.ipcc.ch/sr15/chapter/spm/" target="_blank">primary international body on climate change</a> suggests we need to decarbonize by 2030 to mitigate the worst effects of climate change.</p>
Scant Climate Benefits<p><a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab9335/meta" target="_blank">My recent research</a> suggests that for a system large enough to displace a lot of fossil natural gas, RNG is probably not as good for the climate as <a href="https://investor.southerncompany.com/information-for-investors/latest-news/latest-news-releases/press-release-details/2020/Southern-Company-Gas-grows-leadership-team-to-focus-on-climate-action-innovation-and-renewable-natural-gas-strategy/default.aspx" target="_blank">is publicly claimed</a>. Although RNG has lower climate impact than its fossil counterpart, likely high demand and methane leakage mean that it probably will contribute to climate change. In contrast, renewable sources such as wind and solar energy do not <a href="https://www.eia.gov/environment/emissions/carbon/" target="_blank">emit climate pollution directly</a>.</p><p>What's more, creating a large RNG system would require building mostly new production infrastructure, since RNG comes from different sources than fossil natural gas. Such investments are both long-term commitments and opportunity costs. They would devote money, political will and infrastructure investments to RNG instead of alternatives that could achieve a zero greenhouse gas emission goal.</p><p>When climate change first <a href="https://www.nytimes.com/1988/06/24/us/global-warming-has-begun-expert-tells-senate.html" target="_blank">broke into the political conversation</a> in the late 1980s, investing in long-lived systems with low but non-zero greenhouse gas emissions was still compatible with aggressive climate goals. Now, zero greenhouse gas emissions is the target, and my research suggests that large deployments of RNG likely won't meet that goal.</p>

For all its posturing on climate change, the Democratic Party has long been weak on the actual policies we need to save us from extinction. President Barack Obama promised his presidency would mark "the moment when the rise of the oceans began to slow," and then embraced natural gas, a major driver of global temperature rise, as a "bridge fuel." Climate legislation passed in the House in 2009 would have allowed industries to buy credits to pollute, a practice known to concentrate toxic air in black and brown neighborhoods while doing little to cut emissions.

When an elephant dies in the wild, it's not uncommon to later find its bones scattered throughout the surrounding landscape.
Elephant Burial Grounds<p>Highly social creatures that form deep familial bonds, elephants have long been observed gathering at the site where a peer or family member has died — often spending hours, even days, quietly investigating the bodies or the bones of other dead elephants.</p><p>Although the popular idea that dying elephants are instinctively drawn to special communal graves — so-called "elephant graveyards" — is a myth, their tendency to go out of their way to visit the bones and tusks of the deceased isn't unlike human rituals at graveyards, says animal psychologist Karen McComb.</p><p>"They spend a lot of time touching and smelling skulls and ivory, placing the soles of their feet gently on top of them, and also lifting them up with their trunks," McComb, who's been studying African elephants for 25 years in Kenya's Amboseli National Park, told DW.</p><p>The most striking part of watching an elephant experience loss, Poole recalls, is the quietude. She still remembers one of the first elephant deaths she witnessed; a mother who birthed a stillborn calf. That elephant stayed with its baby for two days, trying to lift it and defending it from vultures and hyenas.</p><p>"I was so struck by the expression on her face and her body. She looked so dejected. It was really like, 'Oh God, these animals grieve…'. It was just so different," Poole told DW. </p>
Witnessing Emotions in Animals<p>Not all scientists are comfortable concluding that elephants grieve. Among the more than 30 reports of elephant reactions to death that Wittemyer co-reviewed in <a href="https://link.springer.com/article/10.1007/s10329-019-00766-5" target="_blank">a study published in November 2019</a> were accounts of "enormous variation and nuance" he says. "It can be incredibly involved and intricate for extended periods or can be relatively cursory checks."</p><p>In Wittemyer's own experience, it can be difficult not to attribute some kind of emotional experience to the more involved interactions between elephants and their dead.</p><p>He shares the story of an "extraordinary event" involving the death of a 55 year-old matriarch in Kenya in a protected area that happened to be near his place of work. She was visited by multiple unrelated families while she was dying, including another matriarch that exerted such enormous effort attempting to lift her to her feet that she broke her tusk, which Wittemyer says, is "like breaking a tooth." </p><p><span></span>"It was a remarkable example of this heightened emotional state, it was very clearly a very stressful interaction," he says.</p>
A Different Sensory World<p>One factor that limits our ability to fully grasp the way elephants process and respond to loss is our markedly different sensory experiences of the world.</p><p>An elephant's world is fundamentally olfactory — based on smell. Ours is visual. Previous <a href="https://pubmed.ncbi.nlm.nih.gov/25053675/" target="_blank">research</a> has shown elephants possess the most scent receptors of any mammal, and can <a href="https://pubmed.ncbi.nlm.nih.gov/17949977/" target="_blank">use smell</a> to discern the difference between different human tribes from the same local area.</p><p>That could explain why elephants exhibit such interest in sniffing the bones and tusks of others, as a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1617198/" target="_blank">2005 study</a> from McCombs highlighted. When presented with the skulls and ivory of long-dead elephants and those from other large herbivores, including rhino and buffalo, McCombs and her team found elephants approached and were specifically attracted to the remains of their own species. </p><p>Without access to the smells an elephant picks up on, Wittemyer says "an enormous amount of stuff" could be missed by humans when studying these behaviors.</p>
