As the dust settles from Rio+20, I finally have a moment to reflect upon the outcomes of the historic Earth Summit Conference. The non-committal nature of the Rio text was a surprise to no one, yet the identification of buildings as an important strategy for the development of sustainable cities and urban infrastructure was still a “win” for the green building movement. Energy efficiency was also recognized as a strategy for combating climate change within both the developed and developing world.
