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

Green Car Congress

These contributions involve a large number of chemical, microphysical, transport and, radiative processes in the global atmosphere. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions. Net warming from contrail cirrus is a sum over the day/night cycle. Gettelman, R.R. Pitari, M.J.

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

Green Car Congress

In the study, the Ford team derived regional CO 2 targets for new LDVs while still providing an integrated view of the global LDV fleet—a perspective critical to the planning needs for global automotive firms. The SMP model calculates 2000?2050 They converted from an absolute amount to scale relative to 2000.

Ford Cut Plant CO2 Emissions By A Third Since 2000; Another Third By 2025 Targeted

Green Car Reports

Ford is doing just that, having cut global carbon dioxide emissions at its plants by over a third since 2000. CO2 emissions have dropped by 37 percent per vehicle between 2000 and 2012.' Ideally, the whole process of making the car should be as environmentally-friendly as possible too.

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. over the previous seven years.

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.

Study finds global CO2 emissions back on the rise in 2010

Green Car Congress

Global carbon dioxide emissions show no sign of abating and may reach record levels in 2010, according to a study led by the University of Exeter (UK). The study, which also involved the University of East Anglia (UK) and other global institutions, is part of the annual carbon budget update by the Global Carbon Project.

Analysis of drill cores links variations in CO2 40M years ago to changes in global temperatures; questions as to the source of CO2

Green Car Congress

Variations in atmosphere carbon dioxide around 40 million years ago were tightly coupled to changes in global temperature, according to new findings published in the journal Science. Algae use photosynthesis to harvest the energy of the sun, converting carbon dioxide and water into the organic molecules required for growth.
