Overarching goals for 2030
Sufficiency is defined as a pattern of use and consumption that not only sufficiently satisfies requirements, but also ensures that consumption, the use of resources and the environmental impact of human activity fall within the 'safe operating space' of planetary boundaries. Various studies, including the 2022 IPCC report, suggest that on the demand side, sufficiency measures can make a significant contribution to reducing greenhouse gas emissions. This goes hand in hand with a reduction in the expansion and storage requirements for renewable energies, which in turn minimises land and resource requirements as well as interventions in nature and the landscape.
To date, there are no comprehensive political instruments that specify concrete quantitative targets for reducing resource consumption. One exception to this is limiting land consumption to 30 hectares by 2030. Nevertheless, it is logical to conclude that every opportunity should be used to take action in order to meet climate and resource targets and safeguard the natural foundations of life. For this reason, it is important to focus thought on 'using less' in all processes and, above all, we must reduce land use, lower comfort expectations and cut down on the use of materials, while at the same time adding value that lasts.
Our Objectives
8.1 Sufficiency in all processes
Sufficiency standards and sufficiency approaches are applied in all processes – from defining objectives and requirements to planning, implementation and ultimate use.
8.2 Sufficiency in land use
Spaces are created on a scale matched to the sustainability goals and intensive use, and frequency of use is actively managed on a building-by-building or city basis.
8.3 Sufficiency in comfort
Targets set for users in terms of heating, visual, acoustic and air hygiene levels and any set standards align with appropriate benchmarks.
8.4 Sufficiency in the use of materials
Materials can be clearly identified, verified and used sparingly over their entire life cycle.
