CDP Releases 2018 Global Supply Chain Report

The number of companies forging ahead with an industry-leading approach to tackling emissions in the supply chain has doubled in a year, according to CDP’s Global Supply Chain Report 2018. But despite a high awareness of climate-related risks, this leadership is not yet spurring wide-scale action down the supply chain, leading to missed opportunities for cutting emissions and costs. https://www.cdp.net/en/research/global-reports/global-supply-chain-report-2018

 

Rewritable Paper from Functional Materials and Systems

By Maria Stournara

The consumption of paper globally has been continuously growing during last three decades, with 300 million tons of paper currently being produced on a yearly basis. The concept precisely relies on the fact that rewritable paper can be reused multiple times based on a “write-erase-write” cycle, therefore, reducing the demands of paper consumption. Reversible writing and erasing occurs through coloration or de-coloration of materials. In their review in Advanced Materials, Prof. Kim and co-authors from the Institute of Nano Science and Technology – INST in Korea, present a detailed overview of concepts, design principles and examples of rewritable paper applications. Depending on the stimulation protocol and mechanistic description of chromism, the article categorizes the approaches depending on the type of materials such as hydrochromic, photochromic, mechanochromic, thermochromic, halochromic, redox dyes and photonic crystals. The authors of the review say, “As it is highly likely that practical applications of rewritable paper will emerge in the future after considerable effort is given to addressing the various key issues, we hope that this review article will serve as stimulus for future research in this area.” http://www.advancedsciencenews.com/rewritable-paper-functional-materials-systems/

 

Elephants Are Very Scared of Bees. That Could Save Their Lives

By Karen Weintraub 

…when bees swarm — and African bees swarm aggressively — hundreds of bees might sting an elephant in its most sensitive areas, the trunk, mouth and eyes. And they hurt. The threat of bees is so intensely felt by elephants that conservationists are using it to help prevent the kinds of conflict that put the behemoths at risk. The endangered animals have sometimes been shot by farmers trying to save their crops from elephants foraging at night for late-night snacks, or by poachers allowed access to help guard the fields. Now there’s a weapon — and a mutually beneficial one — in the arsenal. In recent years, researchers and advocates have persuaded farmers to use the elephant’s fear of bees as a potential fence line to protect crops. By stringing beehives every 20 meters — alternating with fake hives — a team of researchers in Africa has shown that they can keep 80 percent of elephants away from farmland. https://www.nytimes.com/2018/01/26/science/bees-elephants-.html?utm_source=affiliate&utm_medium=ls&utm_campaign=GzQJ77VmgP4&utm_content=486358&utm_term=1&siteID=GzQJ77VmgP4-R.mmoJWG_gAbi0F.gLoBlg

 

Yahoo Adds Sustainability Company Data

This month, a group of nine asset managers including Bill McNabb of Vangauard will write CEOs asking them to expanding their reporting to include data on “key risk factors and mega trends (such as climate change) … For too long, companies have sacrificed long-term value creation to generate short-term results.” Now it’s the turn of the retail investor, as Yahoo Finance joins the discussion. The website has begun offering sustainability scores on more than 2,000 publicly traded companies, furnished by Sustainalytics, the independent supplier of environment, social, and governance (ESG) research. https://www.barrons.com/articles/yahoo-adds-sustainability-company-data-1517599809

 

Barron’s 100 Most Sustainable Companies

By Leslie P. Norton

To create our ranking, we turned to a sustainable-investing stalwart: Calvert Research and Management, an arm of Eaton Vance (EV). Calvert ran one of the first U.S. socially responsible mutual funds and has been applying ESG factors to company research for decades. “What’s essential for investors, the planet, and communities is that sustainability work be done in a way that works within our capitalist system,” says Calvert CEO John Streur. TO ASCERTAIN SUSTAINABILITY, Calvert began by taking the 1,000 largest publicly held companies by market value, with headquarters in the U.S., as of Dec. 31. It excluded real estate investment trusts and master limited partnerships because their sustainability data remain uneven. Then, Calvert looked at 300 performance indicators for each company from data providers including Institutional Shareholder Services, Sustainalytics, and Thomson Reuters Asset4 in five categories: shareholders, employees, customers, planet, and community. The shareholders category included items like accounting policies and board structure; employees, workplace diversity and labor relations; customers, business ethics and product safety; planet, greenhouse-gas emissions; and community, human rights along the supply chain. https://www.barrons.com/articles/barrons-100-most-sustainable-companies-1517605530

 

Celebrate B Corp Month: Small Changes for Big Impact

What Is a B Corp? – Certified B Corporations are for-profit businesses using the power of the marketplace to help solve social and environmental problems. Unlike other certifications, B Corps complete a third-party-verified assessment, administered by the nonprofit B Lab, for the entire operations of the business, from how the products and services are created and deployed to how their workers are treated, and more. B Corps meet comprehensive, rigorous standards of social and environmental performance, accountability and transparency. Every two years, B Corps are re-assessed, and with every assessment must earn an average of 80 points out of 200 possible to gain and retain certification. There are now more than 2,300 B Corps — including names you probably recognize, like Patagonia, Ben & Jerry’s, Eileen Fisher and King Arthur Flour — operating in more than 50 countries and 130 industries. And more are signing up every week. https://bthechange.com/celebrate-b-corp-month-small-changes-for-big-impact-51426cca8a16
