By Lauren M. Graham, Ph.D. On May 5, 2017, Senator Ron Wyden (D-OR) introduced to the Senate Finance Committee legislation focused on reducing carbon pollution over the next decade by incentivizing clean energy and promoting new technologies in the private sector.  The Clean Energy for America Act, which was co-sponsored by 21 Democratic Senators, provides a simplified set of long-term, performance-based energy tax incentives to promote clean energy production and storage.  The...

By Lauren M. Graham, Ph.D. On March 23, 2017, the California Environmental Protection Agency’s Air Resources Board (ARB) announced the release of new carbon intensity pathways for fuels certified under the low carbon fuel standard (LCFS) using the CA-GREET 2.0 model.  Of the 18 pathways approved in March, eight are first generation biodiesel carbon intensity pathways and four are second generation renewable diesel carbon intensity pathways.  A pathway for biodiesel produced from...

On March 24, 2017, Neste, a member of BRAG®, announced its approval of draft proposals by the Swedish government regarding mandated reductions in traffic fuel emissions and the continued tax exemption for high-blended biofuels.  By 2030, the government aims to reduce carbon emissions from transportation by 70 percent.  In addition to reducing carbon emissions, the ambitious targets and long-term perspective will help support innovation and investments in biofuels.  Neste,...

On November 3, 2016, the European Commission announced that 144 new green and low-carbon projects from 23 Member States will be funded by a €222.7 million investment from the European Union (EU) budget, which will be combined with €175.9 from additional investments.  The funding comes from the LIFE programme, the EU’s funding body for the environment and climate action, with the goal of progressing Europe towards a more sustainable future.   The selected projects align...

On October 12, 2016, EPA convened a public advisory committee teleconference of the Biogenic Carbon Emissions Panel.  This advisory meeting discussed comments from chartered Science Advisory Board (SAB) members from the draft report on EPA’s Framework for Assessing Biogenic CO2 Emissions from Stationary Sources.  The SAB panel announced plans to overhaul the current draft report to provide emission examples at various time scales.  This change, to include longer time spans,...

On October 11, 2016, the Biofrontiers platform, a group of industry and civil society stakeholders brought together by the European Climate Foundation, released policy recommendations for the European Union’s (EU) 2030 climate policy.  The group stated that the transport sector has become the largest source of carbon emissions in the EU, and is therefore an urgent area to tackle following the Paris climate change agreement.  Policy recommendations put forth by the Biofrontiers...

On September 21, 2016, Pannonia Ethanol, a Hungarian biofuels company, spoke out against the European Commission's (EC) Low-Emission Mobility Strategy . The strategy recognizes the importance of biofuels in reducing road emissions, and plans on replacing ethanol that is currently being blended into traditional fuels with advanced biofuels. This has spurred concerns for the ethanol industry, as ethanol is increasingly phased out of government emission reduction initiatives in favor of...

On August 10, 2016, Red Trail Energy, LLC, a North Dakota ethanol producer, announced that it, along with the Energy & Environmental Research Center, had been awarded $490,000 to examine the integration of carbon capture and storage (CCS). The study will consist of installing and operating a commercial CCS system in a facility producing approximately 63 million gallons of ethanol and 180,000 tons of CO2, and tracking the technical and economic parameters required. The total...

Canada announced on January 9, 2015, that the New Substances Program has published six new risk assessment summaries for chemicals and polymers, including a summary for multi-wall carbon nanotubes.  Environment Canada and Health Canada conduct risk assessments on new substances.  These assessments include consideration of information on physical and chemical properties, hazards, uses, and exposure to determine whether a substance is or may become harmful to human health or...

The Centers for Disease Control and Prevention (CDC) published a September 20, 2012, Federal Register notice seeking comment on a proposed National Institute for Occupational Safety and Health (NIOSH) exposure assessment and epidemiological study of U.S. workers exposed to carbon nanotubes (CNT) and carbon nanofibers (CNF). The notice states that the proposed research is a cross-sectional study of the current U.S. workforce involved with CNT and CNF in manufacturing and distribution, to be...

The July 3, 2012, edition of the National Institute for Occupational Safety and Health (NIOSH) eNews includes a nanotechnology update, which states that the critical question to address is whether nanomaterials pose health or safety risks to workers employed in their manufacture and industrial use. The update includes the following “notable recent findings and areas of research”:...

The U.S. Environmental Protection Agency (EPA) announced on July 2, 2012, the availability of an external review draft document entitled Nanomaterial Case Study: A Comparison of Multiwalled Carbon Nanotube and Decabromodiphenyl Ether Flame-Retardant Coatings Applied to Upholstery Textiles (EPA/600/R-12/043A). EPA states that the draft document “does not draw conclusions regarding potential environmental risks or hazards of multiwalled carbon nanotubes (MWCNT); rather, it aims to identify...

The NanoRelease Project is intended to support the development of methods to understand the release of nanomaterials used in products. To do this, the Project will: (1) examine full life cycles of nanomaterials in products; (2) work through specific release scenarios at key exposure points of the life cycle; (3) organize existing material characteristics data and measurement methods for those release scenarios; (4) develop a “state of the science” report for release measurement; and (5)...

The U.S. Environmental Protection Agency (EPA) has announced that, in response to public comments, it will provide the public more time to comment on the December 28, 2011, proposed significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). Of particular interest, seven of the PMN substances’ reported chemical names include the term “carbon nanotube” (CNT) or “CNT.” EPA states “the comment period is being...

The U.S. Environmental Protection Agency (EPA) published on December 28, 2011, proposed significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). Of particular interest, seven of the PMN substances’ reported chemical names include the term “carbon nanotube” (CNT) or “CNT.”  EPA states that because of a lack of established nomenclature for CNTs, the Toxic Substances Control Act (TSCA) Inventory names for CNTs are...

On September 18, 2011, Nature Nanotechnology posted an article entitled “Cell entry of one-dimensional nanomaterials occurs by tip recognition and rotation.” The authors state that materials with high aspect ratio, such as carbon nanotubes (CNT) and asbestos fibers, have been shown to cause length-dependent toxicity in certain cells because these long materials prevent complete ingestion, which frustrates the cell. The authors note that, while “[b]iophysical models have...

On May 6, 2011, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as multi-walled carbon nanotubes (MWCNT), which was the subject of premanufacture notice (PMN) P-08-199. Under the final SNUR, persons intending to manufacture, import, or process MWCNT for a use that is designated as a significant new use by the final rule must...

The National Institute for Occupational Safety and Health (NIOSH) released a draft Current Intelligence Bulletin (CIB) entitled Occupational Exposure to Carbon Nanotubes and Nanofibers, which recommends that, until results from research studies can fully elucidate the physicochemical properties of carbon nanotubes (CNT) and carbon nanofibers (CNF) that define their inhalation toxicity, employers should take steps to minimize CNT and CNF exposures of all workers and implement an occupational...
