  • IMO progress on black carbon in Arctic ‘welcome but long overdue’

    The decision at the International Maritime Organisation (IMO) to recommend to its environment committee a definition of black carbon arrived at by scientific consensus, after four years of debate, has been welcomed by environmental NGO Transport & Environment. Lack of agreement at sub-committee level had been holding up technical work to calibrate and test black carbon measurement methods ...

  • Black carbon – the silent killer

    Black carbon - tiny particulate of soot created from the incomplete combustion of diesel fuels, cook stoves, some industrial processes, and from agricultural and forest burning. It can cause serious health issues and is a leading cause of childhood deaths in the developing world. Helping developing nations eliminate black carbon would be quick and easy, argued numerous scientists and experts that ...

  • Black carbon a significant factor in melting of Himalayan glaciers

    The fact that glaciers in the Himalayan mountains are thinning is not disputed. However, few researchers have attempted to rigorously examine and quantify the causes. Lawrence Berkeley National Laboratory scientist Surabi Menon set out to isolate the impacts of the most commonly blamed culprit—greenhouse gases, such as carbon dioxide—from other particles in the air that may be causing the ...

  • European parliament calls for fast action on climate change

    The European Parliament is calling for fast action to reduce non-CO2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. The Parliament's call for action came in a ...

  • Californians Look to LA Testing to Identify “Ghosting” Phenomenon Caused by Soot

    In recent years, companies such as LA Testing have witnessed an increasing number of complaints relating to the sudden and unexpected appearance of soot-like material observed in homes and commercial buildings. These stains may form on carpets, walls, plastic objects and other materials, and are commonly noted around ventilation grilles and electrical outlets.  Often times, the ...

  • Black carbon pollution emerges as major player in global warming

    Soot from biomass burning, diesel exhaust has 60 percent of the effect of carbon dioxide on warming but mitigation offers immediate benefits.  Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to ...

  • Black carbon ranked number two climate pollutant by US EPA

    The US Environmental Protection Agency concluded in a report to Congress that targeted strategies to reduce black carbon "can be expected to provide climate benefits within the next several decades," based on black carbon's strong warming potential and its short atmospheric lifetime of days to weeks.   EPA concluded that black carbon was likely to be causing more warming than any climate ...

  • Fine particles trap more heat in atmosphere than previously thought

    Fine particles in the air produced by road transport trap more radiation in the earth's atmosphere than previously estimated, and therefore may contribute more to global warming than realised, according to new research. In contrast, the impact of particles from shipping appears to reflect more radiation than previously thought, whilst the effect of particles from aviation is comparatively small. ...

  • Ontario’s dirty secret: black carbon and climate change

    To date, Ontario's policy responses to climate change have primarily focused on reducing carbon dioxide emissions from both the energy and transportation sectors or methane emissions from the waste and agricultural sectors. But scientific evidence points to opportunities presented by reducing emissions of short-lived climate forcers, principal among which is black carbon. Black carbon exists in ...

  • New Report Outlines Strategies to Increase Funding for Black Carbon Reduction

    Reducing black carbon emissions could prevent millions of premature deaths annually and play an important role in the global fight against climate change. Yet despite these benefits, an array of black carbon abatement measures that are technically within reach have not yet been financed and deployed to their full potential. A report released today by the Climate and ...

  • California Testing Lab Helps Clear The Air with Wildfire Smoke Damage in Homes

    In recent years, there has been an increasing number of complaints relating to the sudden and unexpected appearance of soot-like material observed in homes and commercial buildings.  These stains may form on carpets, walls, plastic objects and other materials, and have been noted around ventilation grilles and electrical outlets.  The culprit for this “ghosting” phenomenon ...

  • A Tale of Two Cities' Black Carbon Measurement

    Advanced photoacoustic measurement of black carbon particles, using equipment available via UK-based Enviro Technology, has led to a better understanding of pollution in Los Angeles and Mexico City. PAX (Photoacoustic Extinctiometer) Black Carbon Monitors have been deployed to deliver a more accurate picture of daily black carbon trends in ...

  • Black Carbon Emissions Cut 90% in California

    In a first-of-its kind study examining the impact black carbon has on climate in California, researchers found the state's efforts to reduce air pollution, particularly from diesel engines, has cut black carbon concentrations by 90% since 1966. This has happened without any noticeable disruption to the lives of the citizens of California, but with tremendous benefits to their health, as well as ...

  • Health and climate benefits by control of methane and black carbon

    Measures to control methane and black carbon (soot) emissions could improve air quality and public health, in addition to slowing the rate of climate change, according to recent research. By 2030, the reduced pollution could prevent between 700,000 and 4.7 million premature deaths each year, with 80% of the benefits occurring in Asia. Previous studies have linked the formation of ozone at ground ...

  • Reducing Black Carbon Can Save Lives and Help Combat Climate Change

    Black carbon causes millions of deaths every year and contributes to the warming of the planet. In the atmosphere it appears as air pollution, with emissions arising mainly from the combustion of diesel fuel and biofuels, coal-fired power stations, biomass cook stoves, brick kilns and vegetation burning in open fields. The importance of reducing emissions of black carbon and other ...

  • ASTM D3849 - 07(2011) Standard Test Method for Carbon Black—Morphological Characterization of Carbon Black Using Electron Microscopy

    Carbon black morphology significantly affects the transient and end-use properties of carbon black loaded polymer systems. A carbon black's particle size distribution is its single most important property, and it relates to degree of blackness and rubber reinforcement. For a given loading of carbon black, blackness and reinforcement increase with smaller particle size. Aggregate size and shape ...
