Large companies usually make headlines for the bad stuff they do. Pollution, outrageous customer service and casual racism all draw a lot of attention. However, there are some companies that are quietly getting down to the business of helping. These stories don’t make the news as much, since appreciation doesn’t get the same reaction as outrage. The work they’re doing is still important, though. Here are some do-good companies to consider supporting in the next few years.

  1. Tesla

Tesla is well known as an environmentally friendly company. It came out with one of the most popular options for fully electric cars. Elon Musk, the founder and CEO of the company, is personally invested in making Tesla more than just a car company. He wants to make Tesla a renewable energy company, but that takes a lot of work.

Currently, the company only focuses on cars, and introducing electric cars to mass consumers makes a significant impact. A single car produces about 4.7 billion metric tons of CO2 each year. Tesla sold 15,800 cars in one quarter last year. That’s more than 74 trillion metric tons of CO2 that won’t be put into the atmosphere.

  1. GE

Tesla isn’t the only company that’s invested in the green technology game. General Electric has its own initiative dedicated to green technology, called Ecomagination. This initiative has several goals to help the company become greener, including generating $20 billion in annual revenue from its products. That’s enough for some entire companies to be thrilled, but remember, GE is a powerhouse in the energy and manufacturing industries.

Currently, some of GE’s biggest and best products are a new locomotive engine, the Evolution Series Tier 4 Locomotive, which is expected to reduce carbon output by 70 percent over earlier models. In addition, it’s working on new ways to fine-tune wind farms. With digital readings and optimized layouts, it hopes to increase the energy derived from windfarms by about 20 percent.

  1. Apple

Recently, Apple has made some huge leaps toward becoming more environmentally friendly. It’s made a pact to eventually run entirely off renewable energy sources, instead of using any fossil fuels. With a company as big as Apple, this endeavor will take some time, but it’s not messing around to get started.

One of the first things it did was begin construction on two entirely renewable centers in Europe, which coincided with two large solar powered projects in China. It continues to refine the practice by focusing on the company’s largest contributor to its carbon footprint — manufacturing. By refining its manufacturing process to use more renewable sources and recycled materials, it’s gradually working toward a greener technology.

  1. Google

Google has been on the cutting edge of pretty much everything for years, so it should come as no surprise that the company intends to run entirely on renewable energy in 2017. It signed its first renewable energy agreement in 2010, so it only took them seven years to reach that goal. At least, those are the current plans.

That’s only the tip of the iceberg. You’re familiar with Google Street View, but now those cars have added pollution sensors. As they travel the globe, they’re also mapping local pollution levels. They also track illegal fishing, deforestation and use their substantial wealth to invest in other companies that might one day help the planet. The focus is to make Google a big player in the Fourth Industrial Revolution, and to make it a green revolution from the start.

  1. United Technologies

There’s a chance you haven’t heard of United Technologies, but you’ve certainly heard of its customers. Does Delta, Southwest or United Airlines ring any bells? United Technologies (UTC) focuses on air travel. Air travel is a pretty important commodity today, but it’s also a huge contributor of greenhouse gasses. There’s a lot to be done.

One of the most direct contributions UTC has made is with the introduction of its geared turbofan engine. This is a jetliner engine that is expected to cut CO2 emissions by 16 percent. If you can get those on every airliner, there will be a dramatic decrease in commercial airlines’ carbon footprints.

All these companies have a great incentive to start working toward green energy. It saves the planet, makes them money and produces goodwill with customers. The key is to continue upping the green technology output, so we can stave off the worst of what climate change could bring. With companies like this working on it, we might just stand a chance.
