Coca-Cola Co said on Thursday that it would eliminate a major greenhouse gas in its new vending machines and coolers, raising the bar for climate friendly refrigeration in the food and beverage industry.
Coke’s chief executive Muhtar Kent said that the company, which sells everything from soda and juice drinks to water, will replace hydrofluorocarbon (HFC) in its new vending machines and coolers by 2015.
While Coke’s 10 million vending machines, coolers and other refrigeration equipment around the world keep its drinks chilled, they are also the biggest contributor to the company’s carbon footprint.
Together, the refrigeration systems emit 15 million metric tonnes of greenhouse gases each year — about 40 percent of the company’s total.
Greenhouse gases from HFCs are partly blamed for global climate change and are expected to make up 28 to 45 percent of carbon emissions by 2050.
That has prompted the food and beverage industry to find other ways to cool products and cut their environmental impact. Earlier this year Pepsico Inc launched a pilot program for greener vending machines with carbon-dioxide cooling. Coke executives said that carbon dioxide is the company’s preferred replacement, followed by hydrocarbon refrigeration.
While carbon dioxide is a global-warming gas, proponents point to its lower environmental impact — more than 1,400 times less than conventional refrigerants. To ramp up the transition to greener machines, Coke and its bottling partners will buy 150,000 units of HFC-free equipment next year, doubling the company’s current pace for buying the systems.
“Our hope is that our initial investments will trigger adoption by other companies in the food and beverage industry,” Kent said in a conference call with reporters.
He said that wider adoption would help drive the cost of the replacement technology down. Coke has invested US$50 million in research for climate friendly replacements.
DETERRENCE: With 1,000 indigenous Hsiung Feng II and III missiles and 400 Harpoon missiles, the nation would boast the highest anti-ship missile density in the world With Taiwan wrapping up mass production of Hsiung Feng II and III missiles by December and an influx of Harpoon missiles from the US, Taiwan would have the highest density of anti-ship missiles in the world, a source said yesterday. Taiwan is to wrap up mass production of the indigenous anti-ship missiles by the end of year, as the Chungshan Institute of Science and Technology has been meeting production targets ahead of schedule, a defense official with knowledge of the matter said. Combined with the 400 Harpoon anti-ship missiles Taiwan expects to receive from the US by 2028, the nation would have
North Korea yesterday fired about 10 ballistic missiles to the sea toward Japan, the South Korean Joint Chiefs of Staff (JCS) said, days after Pyongyang warned of “terrible consequences” over ongoing South Korea-US military drills. Pyongyang recently dashed hopes of a diplomatic thaw with Seoul, Washington’s security ally, describing its latest peace efforts as a “clumsy, deceptive farce.” Seoul’s military detected “around 10 ballistic missiles launched from the Sunan area in North Korea toward the East Sea [Sea of Japan] at around 1:20pm,” JCS said in a statement, referring to South Korea’s name for the body of water. The missiles
‘UNWAVERING FRIENDSHIP’: A representative of a Japanese group that co-organized a memorial, said he hopes Japanese never forget Taiwan’s kindness President William Lai (賴清德) yesterday marked the 15th anniversary of the Tohoku earthquake and tsunami, urging continued cooperation between Taiwan and Japan on disaster prevention and humanitarian assistance. Lai wrote on social media that Taiwan and Japan have always helped each other in the aftermath of major disasters. The magnitude 9 earthquake struck northeastern Japan on March 11, 2011, triggering a massive tsunami that claimed more than 19,000 lives, according to data from Japanese authorities. Following the disaster, Taiwan donated more than US$240 million in aid, making it one of the largest contributors of financial assistance to Japan. In addition to cash donations and
North Korea tested nuclear-capable rocket launchers, state media reported yesterday, a day after Seoul detected the launch of about 10 ballistic missiles. The test comes after South Korean and US forces launched their springtime military drills, due to run until Thursday. North Korean leader Kim Jong-un on Saturday oversaw the testing of the multiple rocket launcher system (MRLS), the Korean Central News Agency (KCNA) said. The test involved 12 600mm-caliber ultra-precision multiple rocket launchers and two artillery companies, it said. Kim said the drill gave Pyongyang’s enemies, within the 420km striking range, a sense of “uneasiness” and “a deep understanding
