Link to our contribution calculator

If your customers would like to offset a specific amount of carbon equivalent tonnes or donate a monetary value, use our contribution calculator.

You can link to our contribution calculator and prefill either carbon equivalent tonnes or a monetary value. Refer to our link generator to create such a link.

Note that when providing a monetary value, 50% is offset and 50% are donated to the myclimate education fund. If you provide tonnes, the whole amount is offset.

If you want to take users directly to the myclimate cart, use a button with a form:

HTML
<form method="post" action="https://co2.myclimate.org/de/contribution_calculators">
  <input type="hidden" name="contribution_calculator[emission_in_tons]" value="1.17">
  <input type="submit" value="Offset 1.17 t">
</form>

Tracking

It is also possible to add tracking parameters (ps, psuid) to those button-forms, so that the offsets can be tracked back to you.

Use the following HTML for that:

HTML
<form method="post" action="https://co2.myclimate.org/de/contribution_calculators">
  <input type="hidden" name="contribution_calculator[emission_in_tons]" value="1.17">

  <input type="hidden" name="ps" value="eco-team">
  <input type="hidden" name="psuid" value="TR-ID-98237498237498">

  <input type="submit" value="Offset 1.17 t">
</form>

Please contact us to define a partner-string (ps) you can use for this purpose.
