Fraunhofer ISI/ICCT analysis of PHEV data finds real-world CO2 emissions 2-4x higher than official values

Green Car Congress

For their statistical analyses, the researchers made use of anonymized data that vehicle drivers had voluntarily reported to online portals such as Spritmonitor in Germany and MyMPG in the United States. Statistically, private users of vehicles in Germany re-charge their plug-in hybrid vehicle only on three out of four days.

PBL/JRC: Global CO2 emissions increase to new all-time record in 2013, but growth is slowing down

Green Car Congress

Global CO 2 emissions from fossil fuel use and cement production reached a new all-time high in 2013, according to the annual report “Trends in global CO2 emissions”, released by PBL Netherlands Environmental Assessment Agency and the European Joint Research Centre (JRC). in 2013, whereas in the EU emissions continued to decrease, by 1.4%

New Bayesian Approach Addressing Shared Biases Across Models Suggests That Stabilizing CO2 Concentrations at Current Levels Leaves 10% Chance of Exceeding 2C Target

Green Car Congress

” Bayesian statistics incorporate prior knowledge, along with a given set of current data, to make statistical inferences. Lemoine developed a hierarchical Bayesian framework that explicitly represents sources of uncertainty in climate models such as common biases and unknown and unmodeled feedbacks. —Derek Lemoine.

Global CO2 emissions stalled for the third year in a row

Green Car Congress

Information on the other two greenhouse gases, methane (CH 4 ) and nitrous oxide (N 2 O), is only available until 2012, as international statistics on agricultural activities—the main source of these emissions—are not updated as frequently as on energy and industry-related activities. Other greenhouse gases keep creeping up.

Study finds 1.4 Gt discrepancy between national and provincial data sets for greenhouse gas emissions in China

Green Car Congress

The area chart shows the increase of CO 2 emissions calculated from the national energy statistics since 1997 broken down by different fuel type. The dashed line represents the aggregated CO2 emissions calculated from the provincial energy statistics 1997–2010. The column chart presents the 1.4? Source: Guan et al.

Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

Green Car Congress

Most models used to predict future crop production are statistical models that really don’t take full account of the way changes in water, carbon dioxide and temperature interact to affect sugarcane production.

The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change.
