Who Can Change This?

The Ethical Corporation Conference and Reporting Summit (25-26 November 2008, London) was attended by a competent gathering of sustainability experts, consultants, and yes, you’ve guessed it, me! It’s just a little confusing for the common bystander, I daresay. Though as a practiced reporter, I maintain that there is truth to the assertion that reporting is a catalyst to use it. The very character of raising the question: “What have you done about cutting your GHG emissions?” creates an insight that some action is necessary for the reason that certain area if the answer is a disturbing silence.

When everything blows over, how will we be located? The relevant question was asked of Ernst Ligteringen, the CEO of the Global Reporting Initiative. Ernst maintains that it’s more important now than previously that businesses maintain their sociable and environmental responsibility efforts. Since when things get to “normal” back again, (someone will establish normal, one day) the underlying issues such as the environment change, use of resources, poverty, and so on will still be high on the plan.

And those businesses who can responsibly deal with those issues will be best situated. Another estimate from Ernst, in response to the question: “Is the GRI a typical or an instrument?” Ernst says the GRI continues to evolve and symbolizes work in progress. But to all of ordinary people, it looks like a typical, it feels like the standards, it is used such as a standard, and it’s the nearest thing we have to a …

Is Your Fitness Tracker Accurate?

Fitness trackers seem to be everywhere. Millions of individuals have made wearable fitness monitors part of their day-to-day wardrobe, picking out wrist bands to match their belt and shoes. But how accurate are they when it comes to monitoring your degree of physical exercise and estimating how many calories you burn throughout your 30-minute sweat session on the stair mill?

When it involves fitness trackers, there are two general types of displays: accelerometers and heartrate monitors. Accelerometer-based screens, like the Fitbit, use predictive equations using your body’s acceleration in different directions to calculate energy expenditure. NikeFuel Rings falls into this category also, along with FitBug, BodyMedia, Actigraph, and Jawbone.

Heart-rate monitors, on the other hand, use equations predicated on age, elevation, gender, physical-activity level, and relaxing heart rate to calculate the true number of calories from fat you burn off. A closer look at the various models shows that the Fitbit, one of the most popular monitors on the market, appears to be pretty accurate as it pertains to measuring energy expenditure. The mode of exercise can play a huge role in the accuracy of these monitors.

A study released in the Journal of PHYSICAL EXERCISE and Health likened the Fitbit to a lab-based way for estimation of energy costs for various activities during six-minute periods for each. The research workers found the Fitbit to either underestimate or overestimated energy expenditure by 1-25 calories. The smallest distinctions were observed in raking and treadmill running. While 25 calories may not appear …
