An eight-step ladder from an average Western diet to strict vegan. Every step is scored 0 to 100 on three impact axes and three effort axes, where 0 is the baseline diet and 100 is strict vegan. Move the sliders to reweight the impact axes and watch which steps hold their value.
The three weights always sum to 100. Raising one lowers the others proportionally.
Aggregate impact is the weighted average of the three impact axes. Average effort is the unweighted mean of the three effort axes.
Aggregate impact against average effort. Steps are ordered by effort, so up and to the left is better value.
Climate, health and welfare scores against average effort.
Impact gained divided by effort added, measured against the last step that was actually worth taking.
