Incremental dietary shift: impact against effort

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.

Impact weights

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.

The trade-off curve

Aggregate impact against average effort. Steps are ordered by effort, so up and to the left is better value.

Aggregate impact plotted against average effort for each step of the dietary ladder

Impact components

Climate, health and welfare scores against average effort.

Marginal gain per unit effort

Impact gained divided by effort added, measured against the last step that was actually worth taking.
