| Popis: | Circular Economy (CE) is presented today as the way forward to achieving a sustainable and carbon-neutral society. Yet, circularity assessment tools such as Life Cycle Assessment (LCA), Material Flow Analysis (MFA), and Supply and value-chain analysis are currently disconnected from the models used to advise bodies that steer sustainability-driven policies like the Intergovernmental Panel on Climate Change (IPCC). Climate mitigation models (henceforth climate models) are used in policy discussions and international negotiations to track GHG emissions and identify pathways towards a low-carbon economy. One example is the JRC-EU-TIMES model developed by the International Energy Agency or the PRIMES model, which is the backbone of the energy and climate policy of the European Union (EU). These climate models are inherently suitable for representing only linear patterns of economic activity, where GHG emissions are modelled per economic sector (primary energy resource extraction, final energy generation, energy, and materials used in industry, buildings, etc.). But current climate models lack modelling resolution and flexibility to account for the Green Transition measures required e.g. Fit for 55 or RePowerEU goals. Upstream and downstream supply chains are poorly represented, indirect GHG emissions are seldom included (McDowall et al., 2018), and common CE measures – such as extending product lifetime, resource sharing models, and feedback loops of materials and goods - are not considered. This means that, for example, for the cement sector, GHG emissions associated with the production stage are seen by climate mitigation models as the sole responsibility of the cement industry. However, a reallocation of building materials from concrete to raw materials, for example, can provide carbon storage and sequestration, and consequently pledges a reduction of GHG emissions. In addition, citizen behaviour is poorly understood and quantified regarding construction materials CE practices of reuse, recycling, and sharing (Wijkman, 2019). |
