of our earth. For example: for each 1000 kg CO₂ emission, one should invest €123,- in offshore windmill parks (plus in the other CO₂ reduction systems at that price or less). When this is done consequently, the total of CO₂ emissions in the world is expected to be reduced to a level that is in compliance with the Paris agreement. As a result, global warming will stabilize (at a level of 2 degrees C). In short: "the eco-costs of 1000kg CO₂ are € 123,-". Eco-costs 2022

Background information

The eco-costs system has been introduced in 1999 on conferences, and published in 2000-2004 in the International Journal of LCA, and in the ''Journal of Cleaner Production''. In 2007 the system has been updated, and published in 2010. The next updates were in 2012, 2017 and 2022 (2023). It is planned to update the system every 5 years to incorporate the latest developments in science.
The concept of eco-costs has been made operational with general databases of the Delft University of Technology, and is described a

(metals, rare earths, fossil fuels, water, and land-use). For a visual display of the system see Figure 1. Marginal prevention costs of toxic emissions are derived from the so-called prevention curve as depicted in Figure 2. The basic idea behind such a curve is that a country (or a group of countries, such as the European Union), must take prevention measures to reduce toxic emissions (more than one measure is required to reach the target). From the point of view of the economy, the cheapest measures (in terms of euro/kg) are taken first. At a certain point at the curve, the reduction of the emissions is sufficient to bring the concentration of the pollution below the so-called no-effect-level. The no-effect-level of emissions is the level that the emissions and the natural absorption of the earth are in equilibrium again at a maximum temperature rise of 2 degrees C. The no-effect-level of a toxic emission is the level where the concentration in nature is well below the toxicity threshold (most natural toxic substances have a toxicity threshold, below which they might even have a beneficial effect), or below the natural background level. For human toxicity the '

' is used. The eco-costs are the marginal prevention costs of the last measure of the prevention curve to reach the no-effect-level. See the abovementioned references 4 and 8 for a full description of the calculation method (note that in the calculation 'classes' of emissions with the same 'midpoint' are combined, as explained below). The classical way to calculate a 'single indicator' in LCA is based on the damage of the emissions. Pollutants are grouped in 'classes', multiplied by a 'characterisation' factor to account for their relative importance within a class, and totalised to the level of their 'midpoint' effect (

, nutrification, etc.). The classical problem is then to determine the relative importance of each midpoint effect. In damage based systems this is done by 'normalisation' (= comparison with the pollution in a country or a region) and 'weighting' (= giving each midpoint a weight, to take the relative importance into account) by an expert panel. The calculation of the eco-costs is based on classification and characterisation tables as well (combining tables from IPCC

, the USEtox model

, tables of the ILCD

, however has a different approach to the normalisation and weighting steps. Normalisation is done by calculating the marginal prevention costs for a region (i.e. the European Union), as described above. The weighting step is not required in the eco-costs system, since the total result is the sum of the eco-costs of all midpoints. The advantage of such a calculation is that the marginal prevention costs are related to the cost of the most expensive

which is needed to meet the target, and the corresponding level of Tradable Emission Rights which is required in future. From a business point of view, the eco-costs are the costs of non-compliance with future governmental regulations. Example from the past: emissions of Volkswagen diesel. The eco-costs have been calculated for the situation in the European Union. It is expected that the situation in some states in the US, like California and Pennsylvania, give similar results. It might be argued that the eco-costs are also an indication of the marginal prevention costs for other parts of the globe, under the condition of a

Eco-costs 2023

The method of the eco-costs 2023 (version 1.0) comprises tables of over 58.000 emissions and 1600 materials and processes. It has been made operational by special databases for SimaPro and OpenLCA. Excel look-up tables are provided a
www.ecocostsvalue.com
To provide quick benchmarking on materials in Cradle-to-cradle systems, Idematapp 2023 and IdematLightLCA 2023 have been developed for mobile telephones in IOS and Android. For emissions of toxic substances, the following set of multipliers (marginal prevention costs) is used in the eco-costs 2017 system: The characterization ('midpoint') tables which are applied in the eco-costs 2023 system, are recommended by the ILCD: * IPPC 2013, 100 years, for greenhouse gasses (EF version) * USETOX 2 (EF version), for human toxicity (cancer and non-cancer), and ecotoxicity * EF tables for acidification, eutrification, and photochemical oxidant formation (summer smog) * EF tables plus UNEP/SETAC 2016, for fine dust PM2.5 (for PM10 the default factors are used of the ILCD Midpoint+) In addition to abovementioned eco-costs for emissions, there is a set of eco-costs to characterize the 'midpoints' of resource depletion: * eco-costs of metal scarcity (metals, including rare earth) * eco-costs of land-use change (based on

, of vascular plants and mammals, used for eco-costs of tropical hardwood) * eco-costs of water scarcity (based on the Baseline Water Stress indicator - BWS - of countries ) * eco-costs of oil&gas for plastics and transport fuels * eco-costs of uranium The abovementioned marginal prevention costs at midpoint level can be combined to 'endpoints' in three groups, plus global warming as a separate group: Since the endpoints have the same monetary unit (e.g. euro, dollar), they are added up to the total eco-costs without applying a 'subjective' weighting system. This is an advantage of the eco-costs system (see also ISO 14044 section 4.4.3.4 and 4.4.5). So called 'double counting' (ISO 14044 section 4.4.2.2.3) is avoided. The eco-costs system is in compliance with ISO 14008 (“Monetary valuation of environmental impacts and related environmental aspects”), and uses the ‘averting costs method’, also called ‘(marginal) prevention costs method’ (see section 6.3). The issue of the 'plastic soup' is dealt with in the midpoint 'use of energy carriers' (in products). In the calculation of the marginal prevention costs (i.e. the eco-costs) the price of feedstock for plastics, diesel and gasoline, is based on the system alternative of substitution by 'second generation' oil from biomass (pyrolysis of agricultural waste, wood harvesting waste, or algae), and producing bio-degradable plastics from it. By this substitution, the increase of plastic soup is stopped. However, the problem of the plastic soup that exists already is not resolved by this prevention measure. The eco-costs of global warming (also called eco-costs of carbon footprint) can be used as an indicator for the

. However, it is advised to include human toxicity and eco-toxicity, and include the eco-costs of global warming in the calculations on the circular economy as well. The eco-costs of global warming are required to reveal the difference between fossil-based products and bio-based products, since biogenic CO₂ is not counted in LCA (biogenic CO₂ is part of the natural recycle loop in the biosphere).

Since the economic viability of a business model is also an important aspect of the circular economy, the added value of a product-service system should be part of the analysis. This requires the two dimensional approach of Eco-efficient Value Creation as described at the Wikipedia page on the model of the ecocosts/value ratio, EVR. The Delft University of Technology has developed a single indicator for S-LCA as well, the so-called s-eco-costs, to incorporate the sometimes appalling working conditions in production chains (e.g. production of garments, mining of metals).

Prevention costs versus damage costs

Prevention measures will decrease the costs of the damage, related to environmental pollution. The damage costs are in most cases higher compared to the prevention costs. So the total effect of prevention measures on our society is that it results in a better environment at less total costs.

Discussion

There are many 'single indicators' for LCA. Basically, they fall into three categories: * single issue * damage based * prevention based The best known 'single issue' indicator is the

: the total emissions of kg CO₂, or kg CO₂ ''equivalent'' (taking methane and some other

greenhouse gas A greenhouse gas (GHG or GhG) is a gas that Absorption (electromagnetic radiation), absorbs and Emission (electromagnetic radiation), emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse ...

ses into account as well). The advantage of a single issue indicator is, that its calculation is simple and transparent, without any complex assumptions. It is easy as well to communicate to the public. The disadvantage is that is ignores the problems caused by other pollutants and it is not suitable for cradle-to-cradle calculations (because materials depletion is not taken into account).
The most common single indicators are damage based. This stems from the period of the 1990s, when LCA was developed to make people aware of the damage of production and consumption. The advantage of damage based single indicators is, that they make people aware of the fact that they should consume less, and make companies aware that they should produce cleaner. The disadvantage is that these damage based systems are very complex, not transparent for others than who make the computer calculations, need many assumptions, and suffer from the subjective normalization and weighting procedure as last step, to combine the 3 scores for human health, ecosystems and resource depletion. Communication of the result is not easy, since the result is expressed in 'points' (scientific attempts to express the results in money were not very successful so far, because of methodological flaws and uncertainties).
Prevention based indicators, like the system of the eco-costs, are relatively new. The advantage, in comparison to the damage based systems, is that the calculations are relatively easy and transparent, and that the results can be explained in terms of money and in measures to be taken. The system is focused on the decision taking processes of architects, business people, designers and engineers. The advantage is that it provides 1 single endpoint in euro's, without the need of normalization and weighting. The disadvantage is that the system is not focused on the fact that people should consume less. The eco-costs are calculated for the situation of the European Union, but are applicable worldwide under the assumption of a level playing field for business, and under the precautionary principle. There are two other prevention based systems, developed after the introduction of the eco-costs, which are based on the local circumstances of a specific country: * In the Netherlands, 'shadow prices' (the "MKI") have been developed in 2004 by TNO/MEP on basis of a local prevention curve: it are the costs of the most expensive prevention measure required by the Dutch government for each midpoint. It is obvious that such costs are relevant for the local companies, but such a shadow price system doesn't have any meaning outside the Netherlands, since it is not based on the no-effect-level * In Japan, a group of universities have developed a set of data for maximum abatement costs (MAC, similar to the midpoint multipliers of the eco-costs as given in the previous section), for the Japanese conditions. The development of the MAC method started in 2002 and has been published in 2005.Tosihiro Oka, Masanobu Ishikawa, Yoshifumi Fujii, Gjalt Huppes; Calculating Cost-effectiveness for Activities with Multiple Environmental Effects Using the Maximum Abatement Cost Method; Journal of Industrial Ecology, Volume 9, Issue 4, pages 97–103, October 2005 The so-called avoidable abatement cost (AAC) in this method is comparable to the eco-costs.

Five available databases

In line with the policy of the Delft University of Technology to bring LCA calculations within reach of everybody, open access excel databases (tables) are made available on the internet, free of charge (CCBY). Experts on LCA who want to use the eco-costs as a single indicator, can download the full database for Simapro (the Eco-costs Method as well as the Idemat LCIs), when they have a Simapro licence. The eco-costs system, the Idemat LCI database, and a special version of the Ecoinvent database, are also available in OpenLCA The following databases are available: * excel tables o
