Article 99 · Life-cycle costing

1.Where public buyers apply life-cycle costing, this shall, to the extent relevant, cover parts or all of the following costs over the life-cycle of a product, service or works:

(a)costs borne by the public buyers or other parties for purchase of the solution, costs of use, consumption of energy and other resources, maintenance costs and end of life costs, such as collection and recycling costs, based on appropriate baselines and scenario assessments where appropriate;

(b)costs imputed to environmental and climate externalities linked to the product, service or works during its life-cycle, provided their monetary value can be determined and verified.

The costs referred to in the first subparagraph, point (b), may include the cost of emissions of greenhouse gases and of other pollutant emissions or other climate change mitigation costs.

2.Where public buyers assess the costs using a life-cycle costing approach they shall indicate in the procurement detail the data to be provided by the tenderers and the method which the public buyer is to use to determine the life-cycle costs on the basis of those data.

3.The methods used for assessment of costs imputed to environmental and climate externalities shall be accessible to all interested parties and based on objectively verifiable and non-discriminatory criteria. In particular where the method has not been established for repeated or continuous application, it shall not unduly favour or disadvantage certain economic operators.
