Task 3 - Instructions

{% if player.treatment != "Motivated" %} What is this experiment about?

Climate change is a global threat. In this experiment, you can donate some of the {{ Constants.endowment }} Points you earned through your work in Task 1 to climatecare.org, an organisation that eliminates CO₂ emissions from the atmosphere. Your donation will reduce real CO₂ emissions in the atmosphere.

You will see {{ num_projects }} projects, which differ in price and CO₂ emissions saved. In this task, you make your decisions of whether or not to donate to a specific project.

The Meaning of the Xs

Each matrix in the Estimation Task before belonged to one of the {{ num_projects }} projects to which you can now donate. Each X in a matrix represented {{ Constants.real_world_kg_co2_per_x }} kg of CO₂ that your donation will eliminate. This means that if a matrix contained, for example, 100 Xs, your donation to this project will eliminate 50 kg of CO₂ which corresponds to the emissions caused by driving 180 miles in an average car.

{% endif %} The Donation Task

{% if player.treatment == "Motivated" %} In this task you can now donate some of the {{ Constants.endowment }} Points you earned through your work in Task 1. You will see the same {{ num_projects }} projects as in the task before. Projects differ in price and CO₂ emissions saved. {% endif %} When making your donation decision, you will be informed about the price of the donation for this project. You then decide whether or not you want to donate to this specific project. Prices can range between {{ Constants.min_price }} and {{ Constants.max_price }} Points.

We remind you of your estimate of the number of Xs of this project in the previous task. We also translate your estimate of the Xs into how much CO₂ emissions would be avoided by your donation to this project.

{% if player.treatment == "Motivated" %}

If you choose to donate to a project in a round and that round is selected for payment, we will donate the amount to climatecare.org. Your donation will reduce real CO₂ emissions in the atmosphere.

Your bonus payments in this task

If you decide to donate to a given project, and this decision is selected to be the decision-that-counts for your payments, your payments will be determined as follows:

{{ Constants.endowment }} Points - the price of the given project.

If you decide not to donate, and this decision is selected to count, nothing will be subtracted from your earnings from the work task, and you will be paid:

{{ Constants.endowment }} Points.
