Consequences of global warming are appearing much faster than assumed just a few years ago and irreversible ”tipping points” are few years ahead [IPCC, James Hansen]. So far, strategies for mitigation of global warming have mostly been focusing on technological solutions e.g. renewable energy sources (RES) in the supply sector and energy efficiency in the demand sector. Much less attention has been given to potential changes in life style and to alternative economic and social systems. This chapter will focus on non-technological strategies for mitigation of global warming including such questions as national and international equity, “limits to growth”, alternative employment policies, military and security policy and alternatives to traditional GDP as the dominant indicator of welfare and of sound development.
