Most important impact measurement

Most important criteria

The impacts were classified using the value creation model of the International Integrated Reporting Council (IIRC), which subdivides impacts into six types of capital: Financial, Manufactured, Intellectual, Natural, Social & Relationship and Human Capital. We have currently quantified Financial, Manufactured, Natural and Human Capital. In the coming period we will continue to develop processes for quantifying the other types of capital.

The relevant impacts that we have identified are reported as fully as possible.

Impacts are quantified in terms of money (euros) by estimating the sum of the individual impacts on wealth and well-being. Wealth is broadly defined to include all the most relevant impacts on wealth that we have identified. This broad definition also refers to the wealth of people today and later, both in the Netherlands and abroad.

The methods used to calculate the impacts are based on techniques that are commonly applied in scientific and social practice, including the Natural Capital Protocol of the NCC (2016), the Environmental management - Life cycle assessment - Principles and framework ISO (2010) and the General Guidance for Social Cost-Benefit analysis of the CPB. As indicated, further details are available online.

Since Alliander operates in a regulated market and forms part of a broader value chain, impacts are attributed to Alliander based on the attribution method described below.

The wealth effects are conservatively estimated where a choice must be made between various equally reasonable assumptions. Two assumptions are equally reasonable if they are equally acceptable on the basis of the applied criteria and scientific practice and are equally plausible in the eyes of experts. This means that if several equally reasonable assumptions are possible, the assumption resulting in the lowest estimated wealth impact is chosen.
