Eco-Economy: Building an Economy for the Earth
Earth Policy Institute
http://www.earth-policy.org/Books/Eco_contents.htm

[dall'introduzione]
The idea for this book came to me just over a year ago, shortly
after I moved from President to Chairman of the Board of the
Worldwatch Institute, an organization I founded in 1974. In this
new role and with more time to think, three things became more
apparent to me. One, we are losing the war to save the planet.
Two, we need a vision of what an environmentally sustainable
economy—an eco-economy—would look like. And three, we need
a new kind of research organization—one that offers not only a
vision of an eco-economy, but also frequent assessments of progress
in realizing that vision.

The Future is Now vol.2: Equity for a Small Planet
 Now online at: http://www.iied.org/pdf/tfin_Volume2.pdf

 The subjects tackled in this booklet outline some of the most 
significant
 contexts for sustainable development. They address particular 
situations,
 but have more generally applicable lessons and questions. And they 
raise a
 number of critical challenges which should underpin whatever comes out 
of
 the World Summit on Sustainable Development.
