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

Green Car Congress

2050 well-to-wheels (WTW) transportation sector CO 2 emissions in 11 world regions for a number of vehicle types. The researchers used a four-step process in their study: Determining the relative change in global, all-sector CO 2 emissions required for CO 2 stabilization at 450 ppm. Because of the high LDV emissions in 2000?2010,

When peat swamps are drained for agriculture, the peat begins to decompose, and is an enormous source of carbon emissions. Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 —Miettinen et al.
