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

Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Emission rates of BC in the year 2000 by region, indicating major source categories in each region. Black carbon aerosol plays a unique and important role in Earth’s climate system. Source: Bond et al.

UK new car CO2 emissions fell 3.5% in 2010 and more than 20% since 2000

Green Car Congress

Average CO 2 emissions from new cars have fallen by more than 20% since 2000. Cars in the sub-130 g/km CO 2 category represented almost 40% of the market in 2010 compared with less than 1% in 2000. Executive (-28.1%) and Mini (-25.8%) segments recorded the biggest improvements against the levels of 2000. .

A.P. Moller - Maersk to launch methanol-fueled feeder in 2023; all future newbuilds to support carbon-neutral fuels

Green Car Congress

All future Maersk owned newbuildings will have dual fuel technology installed, enabling either carbon-neutral operations or operation on standard very low sulfur fuel oil (VLSFO). Maersk’s methanol feeder vessel will have a capacity of around 2000 TEU and be deployed in one of its intra-regional networks. —Søren Skou, CEO, A.P.

IPCC Scientist Says Climate Change Likely to Accelerate More Quickly and Be More Damaging Than Predicted

Green Car Congress

Without decisive action, climate change this century is likely to accelerate at a much faster pace and cause more environmental damage than predicted, according to Professor Chris Field of Stanford University, and a leading member of the UN Intergovernmental Panel on Climate Change. Chris Field.

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

Green Car Congress

The UN Intergovernmental Panel on Climate Change (IPCC) released a policymaker’s summary of Working Group III’s (WG III) latest report showing that despite a growing number of climate change mitigation policies, annual anthropogenic GHG emissions grew on average by 1.0 GtCO 2 eq (1.3%) per year from 1970 to 2000.
