There is a saying that what gets measured gets improved. For this reason, many organizations are measuring greenhouse gas emissions. In an ideal scenario, carbon accounting is transparent, consistent, accurate, verifiable, and complete. There are now many tools available to assist in the accounting process, including carbon accounting software and consulting firms if you want help crunching the numbers. While many organizations have a handle on the most obvious sources of emissions like business travel, energy use, and paper use, here are a few sneaky sources of emissions you might not have considered.
Although many hardware suppliers have a close relationship with their final assembly plants, there is often little to no information about the primary and secondary components that arrive there for product manufacture. “A lot of electronics components are purely commodities: circuit boards, resistors, chips, transistors, wires,” says Andrew Hutson, director of global value chain initiatives for the Environmental Defense Fund. “They can be sourced from anywhere, a couple of tiers down in the supply chain, and it’s virtually impossible for a company to know where they’re coming from.”
Supply chain transformation may be the answer, but it isn't an easy task. Starbucks achieved transparency by simplifying its supply chain and clarifying functional roles.
Boosting knowledge about the supply chain and the industry can hedge against this issue, and 3rd-party audits are one possible way to increase transparency, depending on the industry in questions.
When Levi Strauss conducted a lifecycle analysis for their jeans, they made some big discoveries that impacted their sustainability strategies. "To our surprise, we learned that 58 percent of the energy and 45 percent of the water used during the lifetime of a pair of Levi’s jeans occurs during the consumer-use phase," says the company. "This is huge and we know it. So we've invited a global dialogue with costumers about how caring for their clothes affects the environment through initiatives such as Care Tag for Our Planet." They now encourage customers to wash jeans every two weeks (instead of weekly), to use cold water, and to line dry.
When considering consumer use, the possibilities are endless. Tide even introduced a new product to encourage consumers to use lower temperatures when washing clothes. Tide Coldwater Clean claims consumers can save 500 pounds of carbon dioxide emission annually by washing in cold water. Microsoft has created software that helps computers use an estimated 27 percent less energy. Such initiatives often begin with a lifecycle assessment to clarify areas of opportunity.
This initiative began with an exploration of the current organizational culture of Iron Mountain and how to enhance it through with a new corporate headquarters. The company has also been looking for creative ways to reduce the environmental impact associated with its vast real estate footprint.
“The greenest and most cost effective square footage we have are the spaces we don’t have,” explains Kevin Hagen, director of corporate responsibility for Iron Mountain.
