Your latest carbon footprint is higher than last year’s. After the work your team has put into reducing emissions, that can be a frustrating result.
Before deciding that the plan has failed, ask what changed. A larger total can reflect increased activity, a more complete inventory, different calculation methods, or a real increase in the emissions associated with your operations. Those explanations call for different responses.
Start with the activities behind the number
Look at your main emissions sources before focusing on the overall percentage movement. Did your vehicles use more fuel? Did production increase? Were there more flights, deliveries or occupied buildings?
If activity increased, that may explain some of the rise. It does not make the additional emissions disappear, but it helps identify whether the issue is growth, efficiency or both.
Use intensity measures alongside the total
Emissions per unit of production, delivery or service can help explain operational performance. Choose a measure that has a meaningful connection to your business and use it consistently.
A manufacturer’s emissions rise from 100 to 110 tonnes while output rises from 1,000 to 1,200 units. Total emissions are up 10%, while emissions per unit fall by about 8%. Efficiency has improved, but the business is still emitting more overall.
Both results matter. An intensity improvement is useful information; it should not be presented as an absolute emissions reduction.
Check whether you are counting more accurately
A new inventory may include a previously missed site, better freight information or a more complete picture of purchased goods. That can increase reported emissions without an equivalent increase in real-world activity.
Explain the improvement and assess whether earlier figures need to be recalculated. Significant structural changes, methodology changes and errors can affect comparability. The applicable reporting framework and your documented base-year recalculation policy should guide the response.
Understand changes in emission factors
Emission factors convert activity, such as litres of fuel or kilowatt-hours of electricity, into emissions. A factor can change because the underlying emissions changed, or because the estimate became more accurate.
Those are different situations. Do not automatically apply a new factor to every historical year. Check the factor’s intended period and guidance, and distinguish revised estimates from genuine changes in emissions.
Give readers an explanation they can follow
Separate the main drivers: activity, coverage, methodology and emissions-reduction actions. Quantify them where you can, and say where you cannot reliably separate the effects.
A useful explanation might say that fuel use fell, freight activity grew, and improved supplier data increased the reported footprint. That tells management much more than “emissions rose”.
The goal is an honest account of progress that helps you decide what to do next. Keep the total visible, explain the movement and adjust the action plan where it is needed.
