Abstract:V zadnjem desetletju pridobivata na pomenu krožnost in trajnost v vseh segmentih družbe. Podjetja, občine in države merijo napredek h krožnosti in trajnosti, a trenutno ne obstaja sistematičen in integriran okvir, ki bi omogočal poenoteno kvantitativno merjenje napredka na vseh nivojih. Magistrsko delo se osredotoča na razvoj integriranega sistema za oceno krožnosti na mikro nivoju. Obravnava analizo prispevkov posameznih kazalnikov, ki jih zbira podjetje, k oceni podindeksa krožnosti posamezne kategorije, npr. vode, odpadkov, energije ipd., ter k oceni skupnega indeksa krožnosti podjetja. Prav tako razišče povezavo med razkrivanjem podatkov v trajnostnih poročilih in možnostjo za njihovo uporabo pri oceni krožnosti podjetja. Ugotovili smo, da se na trgu pojavlja veliko orodij za oceno krožnosti, večina od njih pa ne omogoča podrobnega vpogleda v uporabljeno metodologijo. Večina tudi ne združuje kazalnikov v integrirane indekse krožnosti, ki bi dali informacijo o trendih. Z ilustracijskih primerom ocene krožnosti vode v gospodinjstvu smo ugotovili, da različni sistemi podajo različne končne rezultate ocene krožnosti, a je ob podrobnejši analizi mogoče najti korelacije med posameznimi rezultati. Sistem, ki smo ga zasnovali, je namenjen oceni krožnosti na mikro nivoju, tj. za podjetja, in opredeljuje osnovne kategorije, ki so pomembne za krožno gospodarstvo: voda, odpadki, energija, emisije, poraba materialov. Kategorije sestavljajo kazalniki, ki izhajajo iz podatkov, ki jih zbirajo podjetja. Rezultat metode so podindeksi krožnosti posameznih kategorij ter skupni indeks krožnosti podjetja. Vsi rezultati so izraženi poenoteno z vrednostmi med 0 in 1, pri čemer 0 predstavlja linearnost, 1 pa krožnost. To omogoča večletne primerjave trendov. Rezultati ocene krožnosti konkretnega podjetja za 6-letno obdobje nakazujejo, da vsi kazalniki nimajo enakega vpliva na indeks krožnosti. Če želi podjetje povečati indeks krožnosti, bo največji vpliv doseglo z znižanjem porabe vode, emisij CO2 in NOX ter povečanjem deleža brezogljične električne energije.

Title:Quantitative monitoring of progress towards the circular economy
Abstract:Over the past decade, the circular economy and sustainability have become increasingly important to all segments of society. Businesses, communities, and countries are measuring progress toward the circular economy and sustainability, but there is currently no systematic and integrated framework to measure progress at all levels in a consistent and quantitative way. This master's thesis focuses on developing an integrated system for assessing the circular economy at the micro level. It deals with the analysis of the contribution of each indicator collected by the company to the evaluation of the circular economy sub-index of each category, e.g. water, waste, energy, etc., and to the evaluation of the overall circular economy index of the company. In addition, the relationship between the disclosure of data in sustainability reports and the potential of its use to assess a company's circular economy is examined. We have found that there are many circular economy assessment tools on the market, most of which do not provide detailed insight into the methodology used. Most also do not aggregate indicators into integrated circular economy indices to provide information on trends. Using the illustrative example of assessing the circularity of water in households, we found that different systems provide different final results for assessing circularity, but that when analysed in more detail, it is possible to find correlations between the different results. The system we developed aims to assess circularity at the micro level, i.e., for businesses, and identifies the basic categories relevant to a circular economy: Water, Waste, Energy, Emissions, Material Consumption. The categories consist of indicators derived from data collected from companies. The method results in sub-indices of circular economy for each category and an overall circularity index of circular economy for the company. All results are uniformly expressed with values between 0 and 1, where 0 represents linearity and 1 represents circularity. This allows for multi-year trend comparison. The results of assessing the circularity of a given company over a six-year period show that not all indicators have the same impact on the circularity index. If a company wants to increase its circularity index, the greatest impact is achieved by reducing water consumption, CO2 and NOX emissions, and increasing the share of carbon free electricity.
