# Choose your mode
The UP Scorecard offers two different scoring pathways: [**product comparison mode**](/using-the-tool/choose-your-mode/product-comparison.md) and [**portfolio scoring mode**](/using-the-tool/choose-your-mode/portfolio-scoring.md).
## Product comparison mode
Product comparison mode compares products that provide the same service. For example, you can compare different types of beverage containers:
The scores for [*Climate*](/methodology/the-six-up-scorecard-metrics/climate-impact.md), [*Water*](/methodology/the-six-up-scorecard-metrics/water-use.md), and [*Plastic Pollution*](/methodology/the-six-up-scorecard-metrics/plastic-pollution.md) are calculated for a [standard service amount](/misc/glossary.md#functional-unit) (e.g. 1 liter of beverage served). The qualitative metrics ([*Chemicals of Concern*](/methodology/the-six-up-scorecard-metrics/chemicals-of-concern.md), [*Recoverability*](/methodology/the-six-up-scorecard-metrics/recoverability.md), and [*Sustainable Sourcing*](/methodology/the-six-up-scorecard-metrics/sustainable-sourcing.md)) are based on the material values set by default or on customized properties set by the user.
***
## Portfolio mode
In portfolio scoring mode, you can assess an entire product portfolio:
The scores for [*Climate*](/methodology/the-six-up-scorecard-metrics/climate-impact.md), [*Water Use*](/methodology/the-six-up-scorecard-metrics/water-use.md), and [*Plastic Pollution*](/methodology/the-six-up-scorecard-metrics/plastic-pollution.md) are calculated for all products in the portfolio (e.g. 10 x 250ml cups). The qualitative metrics ([*Chemicals of Concern*](/methodology/the-six-up-scorecard-metrics/chemicals-of-concern.md), [*Recoverability*](/methodology/the-six-up-scorecard-metrics/recoverability.md), and [*Sustainable Sourcing*](/methodology/the-six-up-scorecard-metrics/sustainable-sourcing.md)) are based on the material values set by default or on customized properties set by the user.
You can compare this portfolio to the Best and Worst portfolios (automatically generated by the UP Scorecard).
The Best and Worst portfolios always provide the same service and serve the same foods (or beverages) as your portfolio. But they only include the best-scoring (conversely the worse-scoring) products.
On the other hand, the UP Scorecard allows you to add and compare any other portfolio you have created, regardless of the types of services they provide. This comparison is likely to be most useful when the two portfolios provide the same use cases and number of uses.
