Carbon and capital in one plan.

Many estates keep one plan for keeping buildings running and another for reaching carbon targets. This report explains why bringing them together is usually cheaper, and how to do it.

Why two plans cost more.

Separate capital and carbon plans compete for the same money, and often for the same plant. The result is duplicated work, or replacements made like for like and then replaced again for carbon a few years later.

When carbon work is timed with replacements that are due anyway, the extra cost is far smaller, and the board sees one plan with one set of priorities.

How to bring them together.

  1. One budget, one planRank carbon and condition work together.
  2. Upgrade at replacementSwap to low-carbon plant when the old plant is due.
  3. Price each tonneCompare carbon steps by cost per tonne saved.
  4. Report one pathwayShow progress on carbon and spend side by side.
