  • Bird-friendly building design now also required in Minnesota: Astonishingly, one billion birds die each year as a result of bumping into buildings, mainly building with glass facades. After San Francisco and several municipalities in the Chicago area, the city of Oakland, California and the state of Minnesota are the latest to pass legislation that requires bird-friendly building designs now.
  • Seaweed is reappearing as building material in modern architecture: A new house in Denmark is clad almost completely in bundled seaweed. However this “new building material” is actually an old favorite making its comeback. Seaweed cladding exhibits many positive characteristics, including durability, thermal, and acoustic insulation, and resilience to moisture and vermin. Seaweed houses could also have a negative carbon footprint if  combined with a wood structure, since the stored CO2 exceeds the amount emitted during fabrication and construction.

  • Top six green cities around the world: In 2009 global CO2 emissions totaled 30.4 billion metric tons. Check out how are these top six cities-New York, Vancouver, Copenhagen, London, Amsterdam and Stockholm-embracing the green revolution. The provided infographic compares their efforts in the race to reduce global CO2 emissions by planting trees, promoting energy-efficiency including incorporation of renewable sources, reducing the number of cars, reducing water consumption and with rigorous recycling. According to some scientists, by 2050 we need to reduce our carbon footprint by 80% globally to prevent catastrophic climate changes.
