achieved significant reductions of CO2 emissions over the past several years—with major benchmarks reached and independently certified in 2008. By implementing initiatives such as the Green Power Certification System and the introduction of solar power generation systems, Sony claims it has reduced its global CO2 emissions by approximately 100,000 tons in fiscal year 2008 alone.
In 2008, Sony Europe achieved independent certification that every facility with over 100 employees is powered by 100% renewable energy, amounting to 190 million kWh or approximately 55,000 tons worth of CO2 emissions. Through continuous energy efficiency efforts, Sony's European operations have reduced CO2 emissions by approximately 90% between fiscal years 2000 and 2008.
Sony companies in the U.S. purchased 42 million kWh of renewable energy in fiscal year 2008. This equates to a 25,000 ton reduction in CO2 from renewable energy usage. In April 2009, Sony DADC, a producer of optical disc media, announced that it is purchasing more than 83 million kilowatt-hours of green power in the U.S. annually—enough to meet 44% of the organization's purchased electricity use.
With renewable energy less accessible in Japan, Sony has purchased Green Power Certificates equivalent to approximately 50% of the electricity to be used at Sony City (Sony's headquarters building in Tokyo) beginning October 1, 2009. This represents the entire daytime electricity usage at the building, and is equivalent to the annual electricity consumption of approximately 4,400 households. This is the first time that green energy has been introduced at Sony City, and is expected to result in an annual GHG emission reduction of approximately 6,800 tons. In fiscal year 2008, the Sony Group in Japan purchased a total of 55.49 million kWh in renewable energy through the Green Power Certificate System.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
