The objective of the criterion is to promote the use of products that are transparent with regard to their environmental and social impact throughout the value chain and utilise raw materials extraction and processing methods that comply with recognised environmental and social standards.
The fulfilment of the minimum requirements of the respective raw materials group is demonstrated in the course of the verification by the standard-awarding organisation.
The fulfilment of systemic requirements is a prerequisite for a recognition of the standard.
The "content requirements" establish which environmental and social minimum requirements a standard should formulate and monitor as a principle with regard to raw materials extraction, processing and/or manufacturing of building materials. The content requirements are formulated to be of primary importance in order to enable all raw materials that may be used in construction to be taken into account. If a certain raw material (e.g. wood, concrete or natural stone) is used, the aspects relevant for consideration are those that are "essential" with regard to the respective raw material/product and consequently of relevance. The raw materials-specific allocation gives an overview of this.
The objective is to reduce negative environmental impacts in the area of raw materials extraction and processing. Compliance with the following environmental sustainability goals that are relevant to specific raw materials and are essential for the extraction and processing of the raw materials groups in question must be proven via the standard.
Measures must be taken to protect and preserve biodiversity.
With the exception of natural pure stands, mixed stands with tree types suited to the location are maintained or build up. A sufficient proportion of tree species from the natural forest ecosystem is aimed for. Where foreign tree species are involved, it must be ensured that their natural regeneration does not interfere with the regenerative capacity of other tree types, thereby leading to their displacement.
Genetic or chemical treatment of seeds must be avoided.
Natural fibres must originate from organic farming or animal husbandry.
Natural areas should be converted into a state that is at least equal to the state of the original. The prohibition of deterioration applies here.2.1 Renaturation/recultivation of extraction sites
There must be an obligation to adhere to a prohibition of deterioration. Natural areas must be returned to a state that is at least equal to the state of the original.
Extraction of raw materials does not take place (total conservation areas/"set-aside" areas) or does so only sparingly (environmental sustainability) from areas with particular conservation values. Conservation values are: Biodiversity, natural landscapes, biotopes/habitats, ecosystem services, cultural values, needs of local/resident communities.
A long-term sustainable management plan must exist.
The annual depletion must not exceed 1/100 of the resources that can be extracted annually from known deposits at economically viable expense.
Flood protection, potable water, avalanches, etc.3.1 Monitoring and supervision of environmental impacts
Environmental impacts must be observed, recorded and investigated on a long-term basis. Measures must be taken to monitor these environmental impacts.
The land use must be minimised in order to ensure the preservation of soil and landscapes.
e.g. soil compaction, soil erosion, soil contamination due to the use of chemicals that are harmful to the environment and health or dangerous (substances of very high concern in accordance with REACH))5.1 Soil degradation
Biological, chemical and physical soil degradation must be avoided.
Measures must be taken to preserve the natural water cycle (e.g. preventing impact on surface water levels and/or groundwater levels and their quality, preventing use of large-scale sealants).
e.g. prevention of impact on the water quality through waste water8.1 Recycling von Schmutzwasser
Polluted waste water must not contaminate groundwater or other natural bodies of water. An effective recycling system must be available, in which polluted waste water is cleaned and subsequently fed back into the natural water cycle.
The use of any fertiliser with chemicals that may be harmful to the environment or health or represent a danger must be avoided. Substances of very high concern are outlined in the REACH regulation.
The use of any pesticides that contain chemicals that may be harmful to the environment or health or represent a danger must be avoided. Substances of very high concern are outlined in the REACH regulation.
Measures must be taken to prevent the generation of harmful emissions in order to preserve air quality.
e.g. by using local/regional sources of raw materials11.1. Reduction of transportation
Measures must be taken to avoid transportation (shift to more environmentally friendly alternatives and the use of local sources of raw materials).
The objective is to reduce negative social impacts resulting from the extraction and processing of raw materials. The requirements in the area of social issues are based on human rights conventions and the labour standards of the International Labour Organization (ILO), the ISEAL Assurance Code and the OECD Due Diligence Guidance. Relation to the aforementioned or equivalent standards must be demonstrated as part of the verification process by the standard-awarding organisation.
(ILO = International Labour Organisation)
(Prevention of industrial accidents/protecting workers in hazardous conditions across the entire supply/value chain)
e.g. ensuring the existence of a written contract of employment in accordance with statutory requirements; also applies for subcontractors.
Protection of right to associate and collective bargaining in accordance with ILO conventions nos. 87 and 98
in accordance with ILO conventions nos. 100 and 111
Prevention of resource conflicts and threats to the livelihood of the local population due to possible negative impacts of raw materials extraction, processing or manufacturing of products (expropriation and dispossession of land, forced resettlement or negative impacts on food security).
e.g. preventing corruption, implementing fair business practices and compliance with laws
In the criterion of "Sustainable resource extraction", differentiation is made between various quality levels in accordance with the implementation of the content requirements of a recognised standard.
The standard certifies subcomponents according to the criterion of "Sustainable resource extraction" that are strictly worded, e.g. only the extraction and not the further processing OR only the processing of raw materials and not their extraction. This classification can then only take place if the standard will in future demonstrably include the depiction of the elements of the value chain that are not currently taken into account and the integration has already been announced.
The construction materials/products certified according to the standard fulfil the content requirements that are listed in the criterion (either only environmental or social) with regard to the awarding criteria of the standard. The fulfilment relates to the essential elements of the value chain.
The standard takes into account a "mixture" of certified and non-certified raw materials as part of the certification.
The construction materials or products certified according to the standard fulfil the content requirements that are listed in the criterion (both environmental and social) with regard to the awarding criteria of the standard. The fulfilment relates to the essential elements of the value chain.
The construction materials or products certified according to the standard prove the use of secondary raw materials and fulfil the content requirements that are listed in the criterion (both environmental and social) with regard to the awarding criteria of the standard.
In criterion ENV 1.3 "Sustainable resource extraction", the "content requirements" for standards are explicitly worded in the criterion and designated as such.Download DGNB criteria ENV1.3
