http://www.endseurope.com/12955), McKinsey calculates the potential emission reductions and costs of more than two hundred mitigation actions across ten sectors and 21 regions from now to 2030.
The authors conclude it is technically and economically feasible to cut carbon emissions by 35 per cent by 2030 versus 1990 levels, amounting to a 38-gigatonnes (Gt) reduction. Achieving this would cost E200-300bn annually, below McKinsey's previous predictions and around half of UK economist Nicholas Stern's estimate (EE 30/03/07 http://www.endseurope.com/13290 and EE 30/10/06 http://www.endseurope.com/12571).
McKinsey identifies three priority abatement categories where the cost of action is under E60 per tonne of carbon. First, 14 Gt of carbon could be saved through energy efficiency improvements in vehicles, buildings and industrial equipment, largely at a net profit (EE 14/02/08 http://www.endseurope.com/14701).
Another 12Gt could be saved through the application of low-carbon energy technologies such as wind, nuclear, and hydropower, carbon capture and storage (CCS), and biofuels, the consultants say. These technologies could provide 70 per cent of global electricity in 2030 versus 30 per cent in 2005, they estimate.
Changes in forestry and land-use could save another 12Gt, according to the report. On top of these three main avenues for emission reductions, the authors suggest another 9Gt could be won through behavioural change, albeit at higher cost than E60 per tonne.
But capturing the full potential for emission reductions will be a "major challenge" say the authors (EE 12/11/08 http://www.endseurope.com/17112). It will require global cross-sectoral action and commitment, a strong policy framework, and a start on all this in 2010, they say.Follow-up: McKinsey report http://globalghgcostcurve.bymckinsey.com/ plus reactions from WWF

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
