GE, Unilever, Ricoh and Sprint all have one thing in common. They have woven sustainability into their corporate strategy.

GE has rebranded existing products into “green” products, enabling them to double sales in three years. Unilever setup a corporate-wide challenge – with tangible goals — to reduce water, waste, greenhouse gasses, improve nutrition, hygiene and use sustainable suppliers. Ricoh’s manufacturing facilities have sent zero waste to landfills since 2002, and the company was a strong supporter of the 2015 Paris Agreement to tackle climate change — committing to reduce their emissions by nearly 90 percent by 2050. Sprint recognized that digital equipment such as phones, computers, tablets, etc., are one of the fastest growing categories of toxic waste. They implemented a buyback program that accepts any mobile device, regardless of where it came from, giving customers $300 in account credit for the trade-ins. It’s a sizable investment for Sprint yet it’s also a smart marketing strategy. After all, providing account credit to people also locks them in as customers. Companies are always looking to refine corporate strategy. Green practices are a great place to start.

Ever been on Weight Watchers? The single most effective strategy they give dieters is getting them to write down what they eat. As the old saying goes, knowledge is power. When an organization takes on a sustainability agenda, it is forced to track operational waste by examining the use of energy, supplies, and raw materials. To streamline paper, lighting, and electricity use, these organizations must go through a thorough audit. And it’s just about always worth it.

Organizations might even find that going green requires an upfront investment; LED lights are more expensive than standard bulbs, but last up to 50 times longer. This saves hundreds of dollars per bulb over time. (Quick math: an organization has 10 branch offices. Each branch uses 1,000 bulbs to keep the corridors lit. A $200 savings per bulb could save two million dollars.)

Bottom line: Having a sustainability agenda forces tracking. Tracking creates efficiency.

There are good federal policies encouraging organizations to go green. For one, companies can take a tax credit of up to 30 percent for the use of solar and wind energy. There are other federal tax credits available for developers of energy efficient buildings.

At the state level, states laws are full of tax credits and incentives to encourage sustainability practices. One example: Florida offers a corporate income tax credit to organizations that produce and sell electricity from a renewable energy facility. They also offer a sales tax exemption for companies using solar (and other renewable) energy systems.
