Sustainability Priorities For Global Companies
October 17, 2012 05:46 AM - Editor, Justmeans
Results from the fourth annual "BSR/GlobeScan State of Sustainable Business Poll 2012," released today, outline the progress global business has made on 14 key sustainability challenges over the past 20 years, the areas where business is likely to make the most progress over the next 20 years, and key priorities for the year ahead—including human rights and climate. BSR and GlobeScan surveyed more than 500 business leaders drawn from BSR's global network of nearly 300 member companies. To examine the progress made in sustainability over the 20 years since BSR was founded, the survey asked executives to evaluate the past and likely future progress on 14 key sustainability challenges. Considering the next 20 years, respondents rated sustainability reporting, water, and responsible supply chains as the areas in which business will likely make the most progress. In contrast, respondents were least optimistic about future progress being made in public policy, governance, and employee treatment.
Intercropping with nitrogen-fixing crops leads to increased maize yields, says study
October 17, 2012 05:25 AM - Allison Winter, ENN
Growing maize crops alongside legume trees has been shown to naturally fertilize fields and increase crop yields in many parts of sub-Saharan Africa. As a region known for its extremely volatile climate and it's population facing global hunger issues, this discovery is extremely important for the future of agroforestry in the area. In a study published in the Agronomy Journal by researchers at the World Agroforestry Center, researchers compared yield stability in three scenarios: maize intercropped with the nitrogen-fixing legume tree Gliricidia, continuously cropped monoculture maize receiving inorganic fertilizer, and the typical practice of resource-poor farmers who grow maize without any external input.
Fall Colors and the natural Carbon Cycle
October 16, 2012 06:26 AM - Roger Greenway, ENN
As Fall turns leaves to colorful displays, starting in northern New England, and moving ever southward as Fall progresses, we think of the approaching Winter. We might also think of all the carbon that the once green leaves contain that will be released to the atmosphere as they decay. In the springtime, leaves soak up carbon dioxide from the atmosphere, converting the gas into organic carbon compounds. Come autumn, trees shed their leaves, leaving them to decompose in the soil as they are eaten by microbes. Over time, decaying leaves release carbon back into the atmosphere as carbon dioxide. In fact, the natural decay of organic carbon contributes more than 90 percent of the yearly carbon dioxide released into Earth’s atmosphere and oceans. Understanding the rate at which leaves decay can help scientists predict this global flux of carbon dioxide, and develop better models for climate change. But this is a thorny problem: A single leaf may undergo different rates of decay depending on a number of variables: local climate, soil, microbes and a leaf's composition. Differentiating the decay rates among various species, let alone forests, is a monumental task.
Turning Trash into Art
October 15, 2012 08:57 AM - Kristina Anderson, Sierra Club Green Home
When you think of the words "garbage dump," the first thoughts or images that spring forth from your mind probably aren't related to art. But if you were to visit the Recology collection center in San Francisco, you would be seeing—and thinking about—trash in a whole new way. What you would witness is not only the incredible amount of debris that comes in every day, but also the artists who thrive on it. Twice a year, Recology SF brings in new artists to its Artist in Residence Program, a one-of-a-kind program that utilizes the center as inspiration, as a studio, and as an art supply closet.
Update: Fusion Power
October 13, 2012 07:06 AM - Roger Greenway, ENN
Green house gasses, nuclear waste.....these are concerns with our most widely used power generation technologies, fossil fuel combustion and nuclear fission. Fusion power holds the promise of abundant energy, no green house gas emissions, and little to no waste products. Fusion is getting closer to commercial reality. Until now, it has been produced only in the lab, and only for the briefest of time scales. Scientists in several countries are getting much closer to sustained fusion and this offers the real potential for commercial power production! The crucial next steps on the roadmap to developing fusion energy will be the focus of more than 70 top fusion scientists and engineers from around the world who will gather at the University of California-Los Angeles (UCLA) this month. The Oct. 15-18 session will kick off a series of annual workshops under the auspices of the International Atomic Energy Agency (IAEA) that will address key scientific and technological challenges facing countries developing fusion as a source of clean and abundant energy for producing electricity.
Major Wind Energy Project Approved in Wyoming
October 10, 2012 05:46 AM - Roger Greenway, ENN
The pace of wind energy development on public lands is picking up. Interior Ken Salazar announced this week that the Department has reached its goal of authorizing 10,000 megawatts of renewable power on public lands with the approval of the Chokecherry and Sierra Madre Wind Energy Project site as suitable for wind energy development. The Project is a proposed complex that could generate up to 3,000 megawatts of power in southeastern Wyoming. The project developers expect the proposal to create an estimated 1,000 construction, operation and maintenance jobs and generate enough energy to power nearly 1 million homes. The decision authorizes the BLM to proceed with site-specific environmental analyses for the Sierra Madre Wind Farm, the Chokecherry Wind Farm, the internal haul road, the internal 230 kilovolt transmission line, the rail distribution facility, and substations to connect the generated power to the electric grid. The Record of Decision also approves amendments to the BLM’s Rawlins Resource Management Plan, identifying the project area as available for wind energy development. The BLM Rawlins Field Office oversees more than 3.5 million acres in Albany, Carbon, Laramie and Sweetwater counties.
Update: Lab-grown Meat
October 8, 2012 06:11 AM - Tom Levitt, The Ecologist
Lab-grown meat could help reduce the environmental footprint of intensive farming. But will it ever appeal to vegetarians or even more eco-conscious consumers? Tom Levitt reports Lab-grown meat will create up to 96 per cent less greenhouse gas emissions. Before the end of the year, Dutch scientists are promising a high-profile debut for a burger made from meat grown not on a farm but in their laboratory. Synthetic or lab-grown meat involves taking a small amount of cells from a living animal and growing it into lumps of muscle tissue in the lab, which can then, in theory, be eaten as meat by people.
Stop the trade in Bear Bile!
October 7, 2012 07:43 AM - Miguel Llanos, NBC News
Two brother bear cubs rescued from suspected smugglers in Vietnam have become poster children for a campaign against the use of capturing and harvesting bears for their bile. The two men arrested said "they bought the cubs for $1,500" and were "going to sell them for a much higher price," most likely to a farm that harvests bear bile, Tuan Bendixsen, the Vietnam director for the nonprofit charity Animals Asia, told NBC News. "To get the cubs they would have to kill the mother," Bendixsen added, "and the mother's body parts would be sold" for the trade in purported medicinal cures from bear parts. The body parts most in demand are gallbladders and paws.
Northern forests may become stressed due to increasing outdoor recreation
October 3, 2012 06:20 AM - Allison Winter, ENN
Federal and state park systems in the United States are known for their natural beauty, uninhabited forests and pristine environments. We also think of them for the variety of outdoor recreation they provide. However, as regional populations grow along with the influx of tourists and daily visitors, forests will surely be affected. This increase will call for a greater development of land and water resources as the demand for outdoor recreation expands.
Large Earthquakes create more aftershocks and farther away than previously thought
October 3, 2012 05:14 AM - Roger Greenway, ENN
New research by the University of California has produced significant new data on large earthquakes the related aftershocks that can occur nearby and in distant locations. The largest earthquake in 2012 a magnitude 8.6 temblor on April 11 centered in the East Indian Ocean off Sumatra, did little damage, but it triggered quakes around the world for at least a week, according to a new analysis by seismologists from the University of California, Berkeley, and the U.S. Geological Survey (USGS). The April 11 quake was unusually large — the 10th largest in the last 100 years — and, similar to a few other recent large quakes, triggered small quakes during the three hours it took for seismic waves to travel through Earth's crust. The new study shows, however, that some faults weren't rattled enough by the seismic waves to fail immediately, but were primed to break up to six days later.
