what you do is to compare various entities within an industry segment

e.g Intel has won numerous Green awards, but Hynix (formerly Hyundai Semiconductors) has had their top executives put in prison, not to mention other problems. Beavertron got Intel; Corvallis got hp, and my town got Hynix (who promptly closed their plant when their tax subsidies expired).

another issue is that compliance with new regs. may require capital investment, and if you slice firms by size and further by profitability, you could potentially find a correlation there -- this possibility is why new regs. usually are delayed for smaller businesses

I can cite numerous examples from plywood mills and other forest products firms - it is not limited to tech at all.
