How to avoid the 'climate apocalypse' in 2018 | GreenBiz - 0 views

    The story that should dominate every end of year round up from every media outlet on the planet came last month in the form of two reports released at the U.N. climate summit in Bonn. The first confirmed atmospheric concentrations of carbon dioxide are at their highest levels in at least 800,000 years and possibly 3 million to 5 million years. As Emily Shuckburgh of the British Antarctic Survey said, the last time concentrations of greenhouse gas were as high as they are, sea levels were around 10 meters higher. Up to two meters of sea level rise this century is now entirely plausible. However, the second report was the real kicker. The Global Carbon Project predicted carbon emissions will rise this year after four years when flat emissions fuelled hopes global economic growth and carbon emissions had been decoupled

  • create the world's first bio-based interior textile that doesn't compromise performance, value or aesthetics.
  • In 1981, Carnegie introduced a polyethylene (PE) textile under the brand name Xorel that, at the time, was one of the few healthier alternatives to vinyl (PVC) for interior panels, wall coverings and upholstery. Thirty years later, that product has received an eco-friendly update with the launch of BioBased Xorel, an interior textile made from plants.

  • BioBased Xorel,
  • BioBased Xorel is comprised of 60-85 percent polyethylene sourced from sugarcane instead of fossil fuels
  • but our goal is to source the polyethylene for the entire product line from plants in three years.  
  • We achieved this while keeping the price, aesthetics and performance exactly the same
  • Using a rapidly renewable material reduces our company's dependence on the planet's finite fossil fuels resources
  • sugarcane uses 60 percent less energy and generates 40 percent less greenhouse gas emissions when compared to making petrochemical ethylene
  • sugarcane plant naturally captures carbon dioxide
  • PE takes 2.5 tons of carbon dioxide out of the atmosphere
  • Sugarcane has a much higher yield per acre than corn
  • doesn't require genetic modification
  • Cradle to Cradle certified program

    Production of palm oil - the most widely used vegetable oil in the world - and a strong El Niño have converged into a perfect storm to amplify the effects of Indonesia's dry season. Indonesia produces half of the world's palm oil, which has led to illegal burning to clear land and plant African oil palm trees. Deforestation typically accounts for about 60 percent of Indonesia's total greenhouse gas emissions.
