Prior to the 1990s, there was little concept of corporate sustainability within the textile and apparel industry. However, beginning in the mid-1990s, clothing and apparel corporations began receiving pushback from consumers regarding social, environmental and economic sustainability. In an effort to qualify the process of investing in corporate sustainability, University of Missouri researchers examined two major international apparel brands, Nike and Adidas, to determine the paths taken to reach corporate sustainability. Saheli Goswami, a doctoral student in the MU College of Human Environmental Sciences, says that while both companies are currently models of corporate sustainability, they took very different paths to reach the end goal.

Though cassava is easy to cultivate, it is particularly vulnerable to plant pathogens which can significantly reduce crop yields. With the help of genomics, researchers hope to apply advanced breeding strategies that can improve cassava’s resistance to diseases and improve crop yields.
Evolutionary changes could lead to reduced fishery yields. A new IIASA study shows how alternative management practices could mitigate the problem in a key North Sea fishery.
Although the second-largest and rather concrete metropolis in the United States might not be anywhere near one's immediate association for a biodiversity hotspot, the fly fauna of Los Angeles is quite impressive. As part of BioSCAN, a project devoted to exploring the insect diversity in and around the city, a team of three entomologists report on their latest discovery - twelve new scuttle fly species. Their study is published in the open access Biodiversity Data Journal.
The worldwide reliance on burning fossil fuels to create energy could be phased out in a decade, according to an article published by a major energy think tank in the UK.
Clear-cutting loosens up carbon stored in forest soils, increasing the chances it will return to the atmosphere as carbon dioxide and contribute to climate change, a Dartmouth College study shows.
Women live longer in areas with more green vegetation, according to new research funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. Women with the highest levels of vegetation, or greenness, near their homes had a 12 percent lower death rate compared to women with the lowest levels of vegetation near their homes. The results were published Apr. 14 in the journal Environmental Health Perspectives.
To effectively combat climate change, an ISU economist says we need to better understand the costs. Ivan Rudik says estimates of the damage from greenhouse gas emissions are highly uncertain. Better assessment will help find effective ways to address climate change.

Coral reefs are early casualties of climate change, but not every coral reacts the same way to the stress of ocean warming. Northwestern University researchers have developed the first-ever quantitative “global index” detailing which of the world’s coral species are most susceptible to coral bleaching and most likely to die. Based on historical data, the index can be used to compare the bleaching responses of the world’s corals and to predict which corals may be most affected by future bleaching events.
The western United States relies on mountain snow for its water supply. Water stored as snow in the mountains during winter replenishes groundwater and drives river runoff in spring, filling reservoirs for use later in summer. But how could a warming globe and a changing climate interrupt this process?
A research team confirms that 97 percent of climate scientists agree that climate change is caused by humans. The group includes Sarah Green, a chemistry professor at Michigan Technological University, and is led by John Cook from the University of Queensland.
Must greater prosperity necessarily lead to a greater carbon footprint and increased greenhouse gas emissions? "In theory, no, but in practice this seems to be the case", says researcher Max Koch from Lund University in Sweden. His study of 138 countries is the first ever to take a global approach to the connections between growth, prosperity and ecological sustainability. The study was recently published in the journal article Global Environmental Change.
