SBTi progress tracking

DitchCarbon tracks how much of a portfolio has committed to or set science-based targets over time, weighted by emissions, spend or number of organisations.

How do I track supplier progress against science-based targets?

The chart plots SBTi status across your portfolio year by year. Filter by status, from committed through near-term and long-term targets to net-zero, and choose whether to weight the result by share of embodied emissions, share of spend, or share of organisations.

The weighting choice is the part that changes the answer. Weighted by count, a portfolio can look poor while the organisations carrying most of the footprint are all committed. Weighted by embodied emissions, the same portfolio looks strong.

Both are true, and they answer different questions: one is how far the programme has spread, the other is whether it has reached the organisations that matter.

Supplier engagement targets increasingly get written in the emissions-weighted form, because that is the version that moves a footprint. Tracking both means the target and the report can use the same figure.

The SBTi dataset behind this is snapshotted weekly, so status changes appear within days of publication rather than at the next annual review.

A count of committed suppliers, with no sense of whether they matter.

The same portfolio weighted by emissions, so progress reflects impact.
