Wood is one of the greenest, oldest and most traditional building products available. Wood is a green material because it:
- Is natural & recyclable
- Is a renewable & sustainable resource
- Is long-lasting & durable
- Can be reclaimed & used in other projects
- Uses less fossil fuel to process than other materials
According to the USGBC, 72% of electricity consumption in the United States is from buildings. Wood uses less energy to produce than steel, concrete and aluminum and absorbs carbon from the atmosphere. Wood products also produce less waste than other materials.
The chart below from the AWI (Architectural Woodwork Institute) shows how much less carbon is emitted to produce one metric ton of wood versus other building materials.
Material
(one metric ton) | Net Carbon Emissions* | Net Carbon Emissions
(incl. carbon storage within material) |
| Framing Lumber | 33 kg or 72 lbs | -457 kg** or lbs -1,005 lbs |
| MDF (virgin) | 60 kg or 132 lbs | -382 kg** or -840 lbs |
| Brick | 88 kg or 194 lbs | 88 kg or 194 lbs |
| Concrete | 265 kg or 584 lbs | 265 kg or 584 lbs |
| Plastic | 2,502 kg 5,516 lbs | 2,502 kg or 5,516 lbs |

- eWaste Litters India -
What happens to cell phones, computers and other electronics when we are done with them? They can end up piling up in other countries like India, where e-waste adds up to approximately 1,000 tons per day. This amount could increase by 500 percent by 2020. Some e-waste enters Asian countries illegally, according to Tiny Green Bubble, and is salvaged for parts. In addition to the problem with mass amounts of waste, children living in these countries are also being exposed to dangerous chemicals.
- New Coral Reefs Found -
New coral reefs were found in the Mediterranean off the coast of Tel Aviv, Israel in an area known for sparse sea life. An exploration team from the University of Haifa’s School of Marine Sciences piloting the exploration vessel Nautilus made the discovery. The reefs are located seven hundred meters under sea and may help scientists learn more about their environment and survival.
- Walmart Produce Plans -
Walmart announced a new plan for sustainable agriculture that will help farmers with smaller operations expand their businesses and increase consumer’s access to fresh food. The plan has three major goals: to support farmers and their communities; produce food by reducing environmental impacts and waste; and sustainably source agriculture products, focusing on palm oil and beef production. In the United States, the Heritage Agriculture program will source produce from identified states and regions where agriculture is most successful. More information on the plan is available on Walmart’s corporate website.
- Coffee Cup Recycling -
Starbucks is currently using New York City as a test site for the recycling probability of its coffee cups. The company, which started the test in mid-September and will conclude it in November, is collecting cups at its NYC locations, which will then be sent off to a recycling facility. Currently, Starbucks is only looking at the cups, not the lids or sleeves, but is aiming to provide reusable or recyclable cups by 2015. The company currently uses 3 approximately billion coffee cups per year which pile up in landfills.
- Temperatures on the Rise -
The past decade was the warmest according to scientists, blaming global warming and greenhouse gases in the atmosphere. This data was included in the annual "State of the Climate" report released by the U.S. National Oceanic and Atmospheric Administration in July. Temperatures have climbed steadily, with the 1980s considered the warmest decade until each year in the 90s and 2000s exceeded those numbers.
- Dead Zones Increase -
Ocean dead zones are increasing at a dramatic rate, according to a report from the U.S. government released in September. An ocean dead zone is where hypoxia or low levels of oxygen are found. Marine life have a harder time surviving in these areas and abandon them in search of more oxygen. According to reports, the number of dead zones has increased from 12 in the 1960s to over 300 today. Hypoxia can be caused by several factors, including an increase in phytoplankton, agricultural runoff and overfishing.
