Polycyclic aromatic hydrocarbons (PAHs) enter the environment in large quantities via the combustion of fossil fuels and organic matter. They are a cause for concern given their known toxicity, potential to cause cancer and ability to move large distances in the atmosphere — meaning that they are found in remote or protected areas, such as the Arctic, even if not emitted there. This study explores how PAH levels in the Arctic atmosphere have changed over the past 20 years at three sites in Canada, Norway and Finland. The results show that, despite a global decrease in PAH emissions in the same timeframe, the air concentrations in the Arctic are not significantly declining — possibly partly as a result of local warming causing more volatile PAHs to move from the surface to the air.

IOWA CITY — The University of Iowa on Thursday unveiled new sustainability goals for the next decade that — if accomplished — would cut its greenhouse gas emissions in half from a decade ago and transform the campus into a “living laboratory for sustainability education and exploration.”

But the goals fall short of what a collective of Iowa City “climate strikers” have demanded for more than a year — that the UI end coal burning immediately at its power plant, commit to using only renewable energy by 2030 and unite with the city of Iowa City in a “town-gown” climate accord.

“It’s ridiculous for the UI to announce a 2030 climate plan as it continues to burn coal for years and burn methane-spewing natural gas for decades at its power plant,” said Massimo Paciotto-Biggers, 14, a student at Iowa City High and member of the Iowa City Climate Strike group.

The university’s new 2030 goals piggyback off its 2020 goals, which former UI President Sally Mason announced in 2010 in hopes of integrating sustainability into the campus’ mission.

Her goals included consuming less energy on campus in 2020 than in 2010, despite projected growth; diversifying the campus’ energy portfolio by using biomass, solar, wind and the like to achieve 40 percent renewable energy consumption by 2020; diverting 60 percent of solid waste; reducing the campus transportation carbon footprint with a 10 percent cut in per capita transportation and travel; and increasing learning and research opportunities.

The university, according to a new report made public Thursday, met or surpassed many of those goals — including, among other things, a slight dip in total energy use, despite 15 new buildings and major additions across campus.

The campus also reported 40 percent of its energy consumption comes via renewable energy sources, and it reduced annual coal consumption 75 percent.

As for waste production, the university diverted 43 percent from the landfill and reported diverting 70 percent more waste than in 2010.

In just the first phase, the new 2030 goals — a result of collaboration across campus involving a 2030 UI Sustainability Goal Setting Task Force — involve fewer numbers and hard percentages. Aside from the aim to cut greenhouse emissions by 50 percent compared to a 2010 baseline, the phase one goals aim to:

• Institutionalize and embed sustainability into campus culture, allowing individual units across campus to develop plans to meeting campus sustainability goals.

• Expand sustainability research, scholarship and other opportunities.

• Use the campus as a “living laboratory” capable of improving campus sustainability and ecosystems.

• Prepare students to live and work in the 21st century through sustainability education.

• Facilitate knowledge exchange among the campus community and with the state, nation, and world.

PHASE 2 EXPANDS ON GOALS

As the campus moves into phase two of its 2030 plan, it will expand on first-phase goals by identifying specific and measurable tasks and metrics.

Leadership plans to finalize that second phase later in the fall semester.

“This approach has meant including units engaged in activities such as academics, research, operations, planning, engagement, athletics, and student life,” Stratis Giannakouros, director of the Office of Sustainability and the Environment, said in a statement.

‘Ambitious and forward-looking’

Sen. Joe Bolkcom, D-Iowa City, who serves as outreach and community education director for the UI Center for Global and Regional Environmental Research, told The Gazette the new goals are “ambitious and forward-looking.”

“The new goals will engage students and research faculty to help build a sustainable path for the campus and broader community,” he said.

The university recently made big news on the utilities front by entering a $1.165 billion deal with a private French company to operate its utility system for 50 years. The deal nets the university a massive upfront lump sum it can invest and pull from annually. It gives the private operator decades of reliable income.

And the university, in making the deal, mandated its new provider pursue ambitious sustainability goals — promising to impose penalties if it failed to do so.

Provided are emissions treatment systems for an exhaust stream having an ammonia-generating component, such as a NOx storage reduction (NSR) catalyst or a lean NOx trap (LNT) catalyst, and an SCR catalyst disposed downstream of the ammonia-generating catalyst. The SCR catalyst can be a molecular sieve having the CHA crystal structure, for example SSZ-13 or SAPO-34, which can be ion-exchanged with copper. The LNT can be layered, having an undercoat washcoat layer comprising a support material, at least one precious metal, and at least one NOx sorbent selected from the group consisting of alkaline earth elements, rare earth elements, and combinations thereof and a top washcoat layer comprising a support material, at least one precious metal, and ceria in particulate form, the top washcoat layer being substantially free of alkaline earth components.

Techniques are provided for increasing spectral efficiency over data channels in a storage or communication system. In some embodiments, data may be encoded and transmitted over multiple channels. The transmitted data from the multiple channels may be considered together as a channel bundle, thereby increasing the edge transitions of the group of signals to improve clock recovery and reduce coding constraints. In some embodiments, the channel bit size is reduced to maximize data rates based on the reduced coding constraints. Furthermore, the channel bundle has only one channel with timing markers, so that a receiver may receive information from the channel bundle and recover clocking based on the timing markers in the one channel.

Inventive embodiments are directed to components, subassemblies, systems, and/or methods for infinitely variable transmissions (IVT). In one embodiment, a control system is adapted to facilitate a change in the ratio of an IVT. In another embodiment, a control system includes a carrier member configured to have a number of radially offset slots.

The present invention relates to a method for producing hydrogen, with reduced carbon dioxide emissions, from a hydrocarbon mixture. In said method, the hydrocarbon mixture is reformed so as to produce a synthetic gas that is cooled, then treated in a shift reactor so as to be enriched with H2 and CO2. Optionally dried, said mixture is treated in a PSA hydrogen purification unit in order to produce hydrogen. The residue is treated by means of partial condensation with a view to capturing CO4 before said residue is sent as fuel to reforming.

An emissions recycling system is used on a vehicle towing an agricultural implement to enrich the fertility of the soil. The system includes an exhaust collector for collecting exhaust emissions from the internal combustion engine of the towing vehicle and an exhaust distribution system for injecting at least a portion of the exhaust emissions collected by the exhaust collector into the ground worked by the ground working tools of the agricultural implement. Fertility of the soil is enriched by bioactivity within the soil's micro flora which consumes the greenhouse gas and emissions.
