CARB: clean fuels replaced more than 50% of diesel used in California in Q1 2023

Green Car Congress

The alternative fuel’s CI value is divided by its Energy Economy Ratio (EER) in order to obtain the EER-adjusted CI value, representing the emissions which occur from the alternative fuel per MJ of conventional fuel displaced.

Peking University team develops method for modeling historical global black carbon emissions from motor vehicles with reduced uncertainty

Green Car Congress

Geographical distributions of global BC emissions from motor vehicles in 1976 (A) and 2006 (B). Country-based mean values are shown for 1976 and 1° × 1° resolution was used for 2006. Black carbon is a key short-lived climate change forcer ( earlier post ) and motor vehicles are important sources of BC in the environment.

Study estimates global black carbon emissions up 72% from 1960-2007; BC emissions intensity down 52%

Green Car Congress

Black carbon emissions and BC emissions intensity per year. A study led by a team from Peking University has estimated that global black carbon (BC) emissions increased from 5.3 Historical annual BC emissions in the residential sector (A), industrial sector (B), and motor vehicles (C) from 1960 to 2007.

Unibuss orders 183 Solaris articulated electric buses

Green Car Congress

A central motor with a power of almost 250 kW will be responsible for the drive. The zero-emission Urbino 18 electric buses will replace the older Solaris Urbino model that is used in the city traffic in Oslo. The partnership between Solaris and Unibuss AS dates back to 2006. They will be recharged using a plug-in charger.

Green Car Congress

Projected growth in world carbon dioxide emissions. World carbon dioxide emissions are projected to rise from 29.0 billion metric tons in 2006 to 33.1 The IEO2009 reference case does not include specific policies to limit greenhouse gas emissions. In 2006, non-OECD emissions exceeded OECD emissions by 14%.
