Rather than let liability for these problems be taken up by the public sector or be haphazardly assigned one issue at a time to companies via lawsuits, many accounting reform efforts focus on achieving full cost accounting.

Such moves have made moral purchasing more attractive, as it avoids liability and future lawsuits.
