It’s a familiar debate in the month of December. Eco-minded consumers want to know which is more sustainable: a fresh cut Christmas tree or an artificial one?

This year, an ISO-compliant third-party peer reviewed Life Cycle Analysis (LCA) gives us some insight and helps clear up common misperceptions about the environmental impacts of Christmas trees.

The study, conducted by the international research firm PE International, found that ultimately, consumers need to consider a number of different factors before deciding which type of tree is more environmentally friendly. For instance, the findings show that length of ownership, disposal method and “tree miles” can make a difference regarding which tree is more “green.”

The ISO-compliant third-party peer reviewed LCA was sponsored by the American Christmas Tree Association (ACTA), a non-profit organization representing artificial Christmas tree retailers and real Christmas tree retailers.  Based on the results of the study, the ACTA recommends that consumers demonstrate responsible consumerism by following these steps: (more…)

Earlier this month, the Greenhouse Gas Protocol launched two new standards to help businesses better measure, manage and report their greenhouse gas (GHG) emissions:

• The Corporate Value Chain (Scope 3) Standard reveals opportunities for companies to make more sustainable decisions about their activities and the products they produce, buy and sell. Large and small companies can look strategically at greenhouse gas emissions across their value chain, showing them where to focus limited resources to have the biggest impacts.
• The Product Life Cycle Standard enables companies to measure the greenhouse gas emissions of an individual product. Covering materials, manufacturing, use and disposal, the product standard will help companies improve and design new products and provide insights for more informed consumer choices.

The two new standards were developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD). They were created in response to businesses that want to better understand and measure their climate impacts beyond their own operations, and they’ll enable companies to save money, reduce risks and gain competitive advantage, the Greenhouse Gas Protocol says.

“The new standards provide companies with a comprehensive view of the emissions produced when making a product and across the value chain. They will help companies make better business decisions and stimulate innovation of products and production methods,” explained Björn Stigson, President, WBCSD. “In today’s world, it is necessary to understand and measure the costs for production, labor and transportation of products, which become visible and actionable through emissions.”

Already, these new standards are gaining widespread traction: (more…)

Last week, Cotton Incorporated released a first-ever comprehensive life cycle inventory and life cycle analysis of cotton products.

The study, which took two years to complete, takes a holistic and comprehensive view, focusing solely on cotton (and not competitive fibers).

More specifically, the life cycle inventory (LCI) is a quantification of relevant energy and material inputs and environmental release data associated with the production of cotton from cradle-to-gate (fiber) and manufacturing from gate-to-gate (fabric).

The associated life cycle assessment (LCA) models the environmental impact of representative cotton apparel (a knit golf shirt and woven cotton trousers) from the field through to consumer care, use and disposal (cradle-to-grave).

Cotton Incorporated says the peer-reviewed data and assessment methodology will help direct sustainability research efforts for the cotton industry, as well as to aid textile decision-makers in achieving their own sustainability goals.

Data for the cradle-to-gate segment was collected from the three largest cotton producing countries (China, India, and the United States) and reported as a global average. Similarly, the data for the textile processing phase was culled from surveys among representative mills in the four largest textile processing areas (Turkey, India, China, and Latin America) and are also presented as a global average. Data for the cut-and-sew and consumer use phase were supplemented by a range of credible secondary sources.

US bottle and can recycling rates are lagging. Of the 224 billion beverage containers sold annually, Americans recycle only a mere 29 percent by weight. The remainder is thrown in landfills or incinerated –a huge waste of natural resources.

Fortunately, several major US beverage brands now appear willing to support efforts to reverse that trend.

A new report, Waste & Opportunity: U.S. Beverage Container Recycling Scorecard and Report, from shareholder advocacy group As You Sow, concludes that leading beverage companies are showing both steady, incremental progress on source reduction and a new willingness to support laws making producers financially responsible for collection and recycling of post?consumer beverage packaging.

The report is As You Sow’s third review of the beverage industry since 2006, and the efforts to promote Extended Producer Responsibility (EPR) mandates are new –at least in the US.

“The major development since our last survey has been the willingness of leading beverage companies to consider new legislative mandates requiring them to take responsibility for their post?consumer packaging,” said Conrad Mac?Kerron, Senior Director of As You Sow’s Corporate Social Responsibility Program. “Many beverage and consumer packaged goods companies pay fees in other countries to finance recovery of their packaging. It’s significant that companies are finally acknowledging the need to take responsibility in the US as well.”

Here are a few other key findings: (more…)

New lifecycle assessment (LCA) data from the Dow Chemical Company’s Building Solutions Group shows that thermal insulation plays a key role in the building sector to reduce energy consumption and related green house gas (GHG) emissions.

This new LCA study examined each stage of Dow’s insulated sheathing product’s life cycle (raw material extraction, production, delivery, use and disposal) to determine the total amount of CO2 emissions that occur in order to use the insulation. The results showed that, over the life cycle of Dow’s insulation products, the GHG emissions saved are, on average, 48 times greater than the GHGs emitted to produce, use and dispose of the product itself.

In addition, Dow says the results validate that its insulated sheathing products –when properly installed –are estimated to provide energy-saving benefits that last for more than 50 years.

According to an earlier McKinsey & Company study, improving building insulation is one of the most cost-effective ways to reduce GHG emissions and lower energy costs. (more…)
