# Use case example

Here is a simplified example use case to better illustrate how to use the UP Scorecard in practice.

{% stepper %}
{% step %}

### Context

Let's say we are a small restaurant serving a variety of ramen and beverages and our goal is to cut plastic usage for takeout customers as much as possible since we are concerned about its environmental and human health impact.
{% endstep %}

{% step %}

### Assess current portfolio

Here is an overview of the relevant plastic products used in the restaurant

| Use case     | Food     | Product                                         | Amount per year |
| ------------ | -------- | ----------------------------------------------- | --------------- |
| Hot take out | Hot soup | Single-use polypropylene (PP) plastic container | 15'000          |
| Utensils     | Hot soup | Polylactic acid (PLA) fork                      | 15'000          |
| Cold cups    | Soda     | Single-use clear polystyrene (PS) plastic cup   | 15'000          |
| Straws       | Soda     | PP straw                                        | 15'000          |

Using the [Portfolio Scoring](/using-the-tool/choose-your-mode/portfolio-scoring.md), the above portfolio gets a Summary Score of 21/100 and amounts to a total emission of 3'227'649 g CO₂-eq and 8'659.74 g of plastic leakage.

Further details can be viewed in the Portfolio Dashboard.
{% endstep %}

{% step %}

### Find alternatives

For users who intend to go above and beyond, the UP Scorecard suggests a Best Alternative Portfolio. This is auto-generated and provides the same service and serves the same foods as the provided portfolio, but it only has the best-scoring products, according to the Summary Score in [Product Comparison](/using-the-tool/choose-your-mode/product-comparison.md) mode.

Alternatively, you can now save the portfolio and start a new [Product Comparison](/using-the-tool/choose-your-mode/product-comparison.md) to find better alternatives for each use case.
{% endstep %}

{% step %}

### Assess updated portfolio

Having assessed and found more suitable alternatives, you can edit your initial portfolio and remove/add products based on the assessment in the [Product Comparison](/using-the-tool/choose-your-mode/product-comparison.md) mode. Now look at the new portfolio scores and see how much plastic leakage or greenhouse gas emissions could be saved by switching to more sustainable alternatives. Compare different portfolios to see where the impact of alternative products are biggest.
{% endstep %}

{% step %}

### Implement

Implement the new products in your restaurant's foodware portfolio.
{% endstep %}
