Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000–2018. Pitari, M.J. Prather, R. Sausen, L.J. 2020.117834.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.

GCP Carbon Budget Finds Anthropogenic CO2 Emissions Rose 2% in 2008 Despite Global Financial Crisis; Natural Sinks Not Keeping Pace With Increasing Emissions

Green Car Congress

Despite the economic effects of the global financial crisis (GFC), carbon dioxide emissions from human activities rose 2% in 2008 to an all-time high of 1.3 tonnes of carbon per capita per year, according to a new paper published by an international team of 31 scientists in Nature Geoscience. —Dr Canadell.

Kopernikus Project P2X integrated container-scale test facility produces first fuels from air-captured CO2 and green power

Green Car Congress

Partners of the P2X Kopernikus project on the premises of Karlsruhe Institute of Technology (KIT) in Germany have demonstrated the production of fuel from air-captured CO2 using—for the first time—a container-based test facility integrating all four chemical process steps needed to implement a continuous process.

Constant Ratio Of Airborne To Absorbed CO2 In Carbon Cycle May Indicate Resilient Carbon Sinks

Green Car Congress

The analysis indicates that natural carbon sinks are maintaining overall resilience despite recent signs that the carbon uptakes of specific sinks are in decline. Approximately 40-45% of carbon emissions emitted every year remain in the atmosphere, with the balance absorbed as part of the Earth’s carbon cycle. per decade.

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

The SMP model calculates 2000?2050 The Ford team updated the SMP model with historical data for 2000, 2005, and 2010, and extended the model to calculate the total CO 2 emissions (tonnes) and the TTW (tank-to-wheel) emission rate (g CO 2 /km) for the new vehicle fleet. They converted from an absolute amount to scale relative to 2000.
