How do you measure carbon emissions avoided?

We currently have two types of projects that have a significant impact on carbon dioxide (CO2) emissions: photovoltaic and energy efficiency projects (e.g. LED systems). The way we measure the annual CO2 emissions of both projects differs slightly:

Photovoltaic Projects: based on the fixed value of the first year of operation (marginal user method), we start by estimating the annual production of the installed photovoltaic panels (kWh). We consider this as the energy that is converted into clean energy, once it starts being produced through solar production (as opposed to fossil fuels, which is the national grid's most significant source).

Energy Efficiency Projects: we calculate the energy savings that arise from their installation - the energy that is no longer consumed due to the increased efficiency (kWh).

Once we have done this, we convert the energy into CO2 emissions according to the carbon intensity of the grid (for Portugal this is estimated by the Directorate General for Energy and Geology every year, 258,5g CO2/kWh for 2019).

We take into account the annual savings of the project's first year following its implementation.

You can check the amount of CO2 GoParity has helped avoid through the projects it has helped financed on our impact section. 

You can also check the amount of CO2 emissions each project financed through the platform has avoided clicking in each project in our financed projects section.
