I have only just begun to compile this "master list" from (1) the individual webpages at and (2) other hard-to-categorize NGOs. As I compile these, I'm doing it in batches, so the betalphatizing might be a bit is, in short, just a start...

NGO listings at and beyond

Many subject-specific webpages at contain a section entitled something along the lines of "Institutions" or "NGOs." Keep in mind that sorting them in such a way risks dramatic oversimplification. Take, for example, WWF, one of the more widely recognized environmental NGOs; WWF could be reasonably listed as nature-focused, education-focused, economy-focused, etc. This holds true for  most NGOs. Also note that the NGOs listed on this page and throughout constitute only a partial sampling of the world's thousands of environmental NGOs. The following links contain additional listings
