New technology to define greenhouse gas sources

Scientists know where greenhouse gases are coming from, but for the human eye, it remains invisible.  That is until now, until the announcement of the Hestia system on 9 October 2012. US-based researchers developed this remote sensing system to measure, quantify and visually show carbon and other greenhouse gases through mapping.  By combining also traffic and energy consumption models as well as public data, greenhouse gases and its source can be traced down to street and individual building levels. The advantages are vast – more accurate identification and definition of greenhouse gas generating activities, including level and volume of gas produced.  With this information and quantified data, authorities can set to work to reduce and eliminate carbon emitting activities. No wonder the Arizona State University believes that the Hestia Project will change the entire game field in combatting global climate change.  US cities already under the Hestia-magnifying glass include Indianapolis, Los Angeles and Phoenix.  According to the Hestia-team, two major sources of carbon already identified from the 3-D system are traffic congestion and electricity generation.  This fine scale system is well in advance of the previous broad scale estimations used.  It is also thought that this new system will boost carbon trading, with accurate, real values now on the trading table.
