But consumers are not consuming whatever is available to them. You don't create a product without knowing that somebody would want to buy it. Consumers do make choices. Perhaps some kind of labeling for how environmentally friendly a product and its packaging are? Kind of like calorie content labeling. Eg some estimate of X amount of carbon to produce, package, transport the goods based on country of origin, transport method, raw materials and packaging.

If you try to force producers to take all the burden and blame (like many people are) then you'll just get lied to. People are generally unwilling to accept responsibility for these kinds of things without there being overwhelming evidence.
