Use the Impact Calculator below to calculate what YOU have achieved so far via your contributions to Quick Win projects.

TIP: If you’ve not yet chipped in to any projects and you’d like to get a rough idea of what your intended donation is likely to achieve in its first couple of years, select the Tulgeen image and enter the amount you intend to chip in.

Step 1: Select the project(s) to which you donated. An empty table will be displayed for each selected project.

Step 2: Enter the amount you chipped in. The table will then display what your contribution is achieving at the original project, and also what your donation is achieving indirectly at subsequent projects as loan repayments from the original project flow back into the revolving fund and help fund subsequent projects.

TIP: If you can’t remember how much you chipped in to which project(s), search here.

Note 1: Most browsers display this calculator correctly, but it doesn’t yet operate correctly if viewed via Internet Explorer.

Note 2: For Projects 1 to 13, the ‘subsequent projects’ figures should be a bit higher than shown in the Impact Calculator results. This is because we temporarily used some Big Win funds to help fund some of our early Quick Win projects, and when we later repaid that amount to the Big Win fund we used some loan repayments from those projects to help pay that back. (The apparent under-achievement is particularly large for the Greenbushes project since an unusually large loan repayment from them was used to help pay back the Big Win fund loan.) That money is now all achieving reductions in carbon emissions via the Big Win landlord-tenant solar scheme, but that benefit is not reflected in these calculator results.

Note 3: The ‘install date’ shown in the Impact Calculator output below should really be labelled the ‘switch on date’. It is the date the solar installation was switched on (the day it was connected to the grid). In some cases this is some weeks after the solar panels were installed.
