ABSTRACT

The well-being of animals should be included in many large-scale policy or investment analyses; however, this is almost never done, even though it is common to quantify the consequences for human welfare in these decision analyses. This is partly due to prejudice but increasingly also because we do not currently have good methods for quantifying animal well-being consequences and putting them on the same scale as quantified human well-being consequences. In this chapter, we explain methods for overcoming this ‘problem of interspecies comparisons.’
