Americans Buy Green To Save Money, Not the Climate | Mother Jones
So what's the bad news? Well, it comes in the area of what you might call "efficacy": Americans are buying lots of green stuff, but at the same time, they're markedly less convinced that their personal or individual actions actually make a difference for the climate.
Here, the numbers could certainly be called worrisome: They've declined noticeably since the year 2008, when 48 percent of the public said that they thought their "energy-saving actions and intended actions" would significantly reduce their contribution to global warming. That's now down to just 31 percent. Similarly, in 2008, 78 percent of the public thought that "if most people" in the country did the same, "it would reduce global warming 'a lot' or 'some.'" Now, that's down to 56 percent.
Indeed, looking forward, the study found that Americans overall will be changing their airline travel patterns less out of global warming concern in the future.
