It would be impossible to get much agreement on which set of ethics to use. The Choice Community and subscribers are by no means homogenous. For example, on environmental issues some would say ignoring environmental consequences is unethical and others not - or that the problem is illusory so there is no question of ethics.
Also it would be impossible to measure which would leave making qualitative judgements. These would be based on limited evidence that could be disputed. As Choice could hardly travel the world inspecting factories (or gathering other data first hand) if some other party supplying data got it wrong or if a vendor felt particularly aggrieved there could be court cases.
