IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. giga tonne carbon dioxide equivalent (GtCO 2 eq) (2.2%) per year from 2000 to 2010 compared to 0.4

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

In a fairly bleak assessment of global progress towards low-carbon energy, the International Energy Agency (IEA) concluded that, despite a few bright spots such as the rapid expansion of renewable technologies and the growth of hybrid and EV sales, the progress is far below that required to achieve a 2 °C pathway—i.e., Source: IEA.

Study Concludes Large Scale Use of Miscanthus Could Reduce Atmospheric CO2 Concentration by 162 ppmv by End of Century; Carbon Debt Payback in 30 Years

Green Car Congress

They estimate payback of the Miscanthus carbon debt—the carbon emissions cost of displacing natural vegetation—in 30 years. Previous estimates for other liquid biofuels, such as corn ethanol, were estimated to take 167-420 years to pay back their carbon debt.

KPMG study identifies 10 sustainability “megaforces” with accelerating impacts on business; imperative of sustainability changing the automotive business radically

Green Car Congress

KPMG developed 3 nexuses linked by climate change to represent the challenges of sustainable growth. The KPMG research finds that the external environmental costs of 11 key industry sectors jumped 50% from US$566 to US$846 billion in 8 years (2002 to 2010), averaging a doubling of these costs every 14 years.

Draft of EPA Greenhouse Gas Inventory Shows Overall GHG Emissions Down By 2.9% in 2008; Transportation Emissions Down 5.7% in Largest Annual Change Recorded Since 1990

Green Car Congress

This report attributes the downward trend primarily to the decrease in demand for transportation fuels associated with the record high costs of these fuels that occurred in 2008.

EC JRC report explores future of road transport; moving away from system centered on private car ownership

Green Car Congress

The Joint Research Center (JRC), the European Commission’s science and knowledge service, has released a report exploring the future of road transport, given the advent of automated, connected, low-carbon and shared mobility. The growth in road passenger transport is estimated at 16% during 2010-2030 and at 30% for 2010-2050.
