Comprehensive assessment concludes black carbon second-most important human emission in warming climate

Green Car Congress

A comprehensive assessment of black-carbon climate forcing accepted for publication in the Journal of Geophysical Research: Atmospheres estimates that black carbon, with a total climate forcing of +1.1?W?m m -2 , is the second-most important human emission in terms of its climate-forcing in the present-day atmosphere.

NASA-led study finds 50 vol% biofuel blend reduces soot particle emissions during aircraft cruising; reduced climatic impact of contrails

Green Car Congress

Of these effects, the largest uncertainties are associated with aviation-induced cloudiness, both directly from contrail-induced cirrus clouds and indirectly from the contribution of black carbon, organic and sulfate aerosols that may act as cloud condensation nuclei and ice nuclei. —Moore et al.

MAN ES and research partners to develop methanol retrofit solutions for medium-speed marine engines; CliNeR-ECo

Green Car Congress

The three-year research project, ‘ CliNeR-ECo ’, is funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK) with initial work having already commenced at the beginning of 2023. For us, the path to the decarbonization of the maritime economy begins with the switch to climate-neutral fuels.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

ARB: carbon intensity of biomethane from wastewater sludge could be as low as -65.27 g CO2e/MJ

Green Car Congress

Staff estimated the carbon intensities (CIs) for biomethane produced under two alternative scenarios; under the first scenario, the CI of biomethane is 10.86 In this model, the majority of the biogas is allocated to the production of renewable power using a device such as a gas-fired turbine with an exhaust heat recovery system.
