Final session on international mercury convention this week expected to culminate in agreement; UNEP Global Mercury Assessment 2013 finds industrial source Hg emissions may be rising

Green Car Congress

Unintentional emission sectors: Coal burning, ferrous- and non-ferrous (Au, Cu, Hg, Pb, Zn) metal production, cement production. The 2013 assessment is the most comprehensive to date, and includes information on the release and impacts of mercury in aquatic environments for the first time. Source: UNEP. Click to enlarge.

Emissions of Air Pollutants down in EU-27

Green Car Congress

The European Community’s air pollutant emission inventory report released by the European Environment Agency finds that in 2007, sulphur oxides (SO x ) emissions were down by 72 % from 1990 levels. Energy use by households (the burning of wood, gas, coal etc) is the most important source of PM 2.5

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

Shale gas in particular has grown rapidly, from less than one percent of US production in 2000 to 34% in 2012, and projections show strong production growth continuing for the foreseeable future. With this abundance of natural gas comes a variety of questions.

Shell updates energy scenarios; world entering an era of volatile transitions

Green Car Congress

In summary, Shell believes that the world is entering an era of volatile transitions as the effects of energy consumption on the environment become increasingly clear. Underlying global demand for energy by 2050 could triple from its 2000 level if emerging economies follow historical patterns of development. Zone of uncertainty.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

For comparison, they also modeled the production of methanol using only biomass as a fuel and also using coal as source of both carbon and energy. Solar-Driven Biomass Gasification Biomass-Fired Biomass Gasification with CO 2 Capture Coal Gasification with CO 2 Capture. Ten percent of carbon is oxidized and released to the environment.
