4. Letting the Loudest Voice Win
While the TBL-CBA analysis often points out trade-offs between people, planet and profits and highlights distributional effects across affected stakeholder groups, don’t fall into the trap of implicitly weighting one group or sector more than another. Cost-benefit analysis does the weighting for you. For example, a quantity of water used or saved, when multiplied by the social cost of water (which accounts for regional scarcity) will show up as more material if there is a lot of water used. Likewise, if a project uses minimal energy, even when multiplied by the social cost of carbon emissions, energy likely won’t be a material factor.
One of the most compelling attributes of TBL-CBA is its objectivity.
