My recommendation is to ignore funds that claim to invest
in socially responsible companies. Rather take a portion of
your returns and contribute them to whatever causes you
feel strongly about (anti-smoking, tropical rain forests, etc.)
The money that you invest in the secondary market (assuming
you don't participate in IPOs) doesn't go directly into the coffers
of Phillip Morris International. It has negligible effect on their
operations.
Quoting Andrew Tobias from "My Vast Fortune":
Socially Responsible Investing
"Forget it. By and large, I've always been fairly cold-blooded
about this -- the notion of shunning investments in
companies that have subsidiaries in South Africa (back
before the fall of apartheid) or that make cigarettes or
bombs. I think I'm as anti-apartheid, anti-tobacco, and
anti-bomb as most, but that limiting my investment choices
will ordinarily do no good at all (except maybe to make me
feel good), while reducing the returns I earn and then
contribute to fight apartheid, tobacco, or bombs."
