In this step you can review your unit impact based on the values you have input for the solution unit emissions and incumbent unit emissions. The unit impact is calculated by subtracting the solution unit emissions from the incumbent unit emissions. This difference is referred to as the .

Review your unit impact
This step is for you to check your emissions data and assess whether or not the values are realistic.
A positive value means your solution unit emissions are lower than the incumbent unit emissions. You can also see this as the “emissions savings” per unit sold. We will expect a climate technology to have a positive unit impact, as you are aiming improve performance of an existing technology (the new solution should have a lower impact than the existing). This value should always be positive.
A negative value means your solution unit emissions are higher than the incumbent unit emissions. This means your solution is more polluting than the existing incumbent solution. In this case you should check if the values you’ve input in the previous steps are correct.
Cross reference your unit impact
You can review the references by clicking back and forth between the incumbent and solution unit emissions data and determine whether the proposed unit impact is feasible. You can do a quick check by calculating the percentage improvement the solution unit provides compared to the base case.
For example:
* Disclaimer for this example: there are also sources that state that indicate cultivated meat has a higher impact than traditional beef. It is up to the user to determine which sources to rely on and utilize for the assessment.
FAQs
How do I take into account emission factors? Where do I get emissions factors from?
Emissions factors relate the unit of the solution to an amount of pollutant emitted to the environment.
From Project Frame’s perspective, the pollutants of interest are GHGs. As such, emissions factors will typically be expressed in terms of kg CO₂e per unit of the solution being analyzed. Emissions factors often come from life cycle analysis or assessment (LCA), which is a cumulative accounting of all current measured GHG emissions connected to a particular product or process within a specified system boundary.

.What if my unit impact is not in line with what I’ve researched?
This is a time for you to critically evaluate the model. Perhaps the input data from the incumbent or solution unit emissions is outdated and needs to be updated. Check for things such as region specific data, as emissions factors for energy usage change drastically depending on your location.
