The World's Greenest Companies: IBM, HP & Johnson & Johnson

4 min
IBM, HP and Johnson & Johnson’s sense of corporate responsibility ranks them the greenest companies in the world


In 2010, Newsweek and media partner ASAP Media, in collaboration with MSCI Research, Trucost, and, set out to uncover the “greenest” companies in the world.  MSCI Research is a leader in environmental, social, and governance ratings.  Trucost specializes in quantitative environmental performance measurements. is the world’s largest online directory of environmental, sustainability, and social responsibility reports. 

The findings assign large publicly traded international companies with various performance-based scores.  The Environmental Impact Score is based on over 750 metrics and calculates overall environmental footprint.  The Green Policies and Performance Score is a comprehensive assessment of the companies’ environmental initiatives.  The Reputation Survey Score is based on a poll of CEOs, environmental officers and other experts.  Finally, an overall Green Score encompasses all the others and decides ranking.

However, what Newsweek has neglected to provide in its Green Rankings is an actual description of exactly how each company is going green.  That’s where we come in.  Let’s break down the top three companies on the list to see just what going “green” means for these corporate role models.

3.  Johnson & Johnson

Green Score: 98.51

Since 1987, Johnson & Johnson has initiated environmental and efficiency programs to “green” the company in three distinct areas.

CO2 Emissions Reduction

J & J has been working to achieve a goal of reducing CO2 emissions by seven percent from 1990-2010, but actually achieved a 12.7 percent reduction.  Another goal was to reduce vehicle fleet emissions per mile driven by 30 percent.  To help meet this goal, the company has added over 2,100 hybrid vehicles to its fleet.  

Renewable Energy

J & J is one of the founding members of the U.S. Environmental Protection Agency’s Green Power Partnership, and was honored as Green Power Partner of the Year in 2003, 2005, 2006, and 2007.  The company has directly purchased wind and on-site solar PV power units and renewable energy certificates are purchased from wind power and biomass facilities.  A recent investment in Ireland saw the country’s first biomass boiler to be used in a pharmaceutical manufacturing facility, using leftover woodchips from sustainably-logged forests as carbon neutral fuel.  


As one of the largest providers of packaged consumer goods, J & J has reduced packaging by incorporating at least 30 percent post-consumer recycled content or fiber from sustainably harvested forests in 93 percent of office paper and 83 percent of paper-based packaging.  J & J has also pushed to remove PVC from its packaging, eliminating it in 84 percent of secondary and tertiary packaging. 

“Sustainability is a process,” says Michael Maggio, Vice President, Johnson & Johnson Group of Consumer Companies, Global Strategic Design Operations. “We start with small steps and then improve as we go.”


Green Score: 99.33

HP is one of the leading IT firms going green.  The company was the first to introduce Energy Star® rated PCs, and since has released a whole line of computers, monitors, televisions, and printing and imaging products with Energy Start® certification. 

In 2006, HP partnered with the World Wildlife Fund to reduce CO2 emissions by 15 percent come 2010.  The company also reports and verifies carbon dioxide emissions from its facilities, based on the Greenhouse Gas Protocol and the World Economic Forum’s Global Greenhouse Gas Registry.  HP boasts some of the most energy efficient data centers in the industry.

HP promotes an extensive IT recycling program, and in 2006 alone reported 164 million pounds of IT equipment recycled.  The company is hoping to reach 1 billion pounds recycled by the end of 2011.

HP has even released a limited edition “Green IT for Dummies” guidebook in collaboration with the “For Dummies” brand book series to help other organizations in their greening efforts.

1. IBM

Green Score: 100

IBM holds rank as the “World’s Greenest Company,” and one major factor setting them on top is the creation of the world’s greenest data center at Syracuse University.  The data center was designed from the ground up with energy efficiency in mind, and boasts 50 percent less energy consumption than most other data centers. 

IBM has worked for the last 20 years to reduce energy and water consumption.  Between 1990 and 2010, the company reduced energy consumption by 5.1 kilowatt hours.

IBM has also developed its Sustainable Management System Technology to help clients operate their commercial buildings more efficiently.  In fact, IBM is a leader in expanding “smart” grid technology throughout the world, utilizing intelligent software to manage energy efficiency in entire cities. 

"Smarter energy is not some futuristic ideal,” says IBM CEO Samuel Palmisano. “For one thing, there are real examples being deployed around the world.  Smarter energy is practical because it's not ideological."

Itronics successfully tests manganese recovery process

Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.

Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.

The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content. 

In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.

Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.

"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president. 

“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.

"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.

Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.

Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.

A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.

The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
