Creating a List of Companies

These are some of the main sources that will let you create a list of companies that match criteria you specify (such as where they are located, their industries, size, etc.). There are additional places to search specifically for SGE-related job postings on the Sustainability Jobs tab.

Keep in mind, many larger companies may not entirely focus on SGE issues, but will have divisions or positions that do.

Finding Industry Codes

What is an industry code?

SIC and NAICS are classification systems for industries. They allow you to group together companies in a specific industry in a standardized way.  

Where can I find industry codes?

The Census website has SIC and NAICS codes and code definitions.

For example, the NAICS code for alternative energy (e.g., geothermal, ocean wave, solar, wind) is 237130.

Search Tips

six-sided die with question marks on all sidesHey, there are some companies missing!

If you have tried the search on the left you might have noticed that a major player in the windmill industry, General Electric, is missing from the results list! Even though General Electric is based in Rochester, GE Wind is based in California and so in this case the database limits your search results as such.

To avoid this problem start broad:

  • Do not limit the location for your first search.
  • Use broader industries and use the appropriate industry code to search for your companies. Many databases will have GE Wind listed as a turbine manufacturer (SIC:3511, NAICS:333611) rather than an alternative energy manufacturer.
  • Use more than one resource when creating lists of companies.
