The objective of this Special Issue in the Ecosystem Services journal is to open up a new frontier of trailblazing research that will build on the common challenges, synergies and overlaps between two complementary research fields – on ecosystem services (ES) and life cycle assessment (LCA) – and interactive web-based databases to support environmental decision-making. This can create the foundations for an international, credible, and acceptable ES governance standard as well as new directionalities to capture i) on one hand, the value of environmental externalities and embed it into decision-making through robust guidelines, toolkits, databases and standards, ii) on the other hand, novel or emerging solutions and stimulate new research at the interface between ES and LCA to facilitate ES governance, broadly intended as a current gap in both knowledge and practice.
Nowadays an increasing demand from public and private sectors exists for environmental accounting and assessment of products and services that may encompass the consideration of ES, encouraging comprehensive ecosystem footprinting analyses, valuation and standardization as tools to improve decision-making on ecosystem conservation, restoration and sustainable production and consumption. These are proven to be successful at the “territorial” scales of socio-economic system (urban, region, nation,…), where the interaction between man- and nature-based processes is mainly driven by land uses. While high data collection and monitoring costs generally hinder those evaluation tasks, established techniques for optimal ecosystem services assessment (ESA) exist and innovative solutions for integrated impact assessment (IIA) are emerging. More specifically, public and private sector investors, multilateral and intergovernmental authorities, regulators, landowners and land users, entail best-in-class, customized and harmonized standard monitoring and management practices, instruments and guidelines to systematically incorporate considerations related to the impact on ES in their decision-making processes. However, mainstreaming ESA and IIA knowledge into policy and decision-making practice requires the harmonization of definitions, the standardization of classification processes, the generation of comprehensive databases and the streamlining of methodological and epistemological properties of ES accounting, quantification, valuation and mapping approaches.
In this regard, recent efforts to combine ES valuation methodologies with the LCA and related approaches show promising avenues to overcome the current taxonomic and methodological challenges to quantify and valuing ES. One of the strengths of LCA is that this method is under continuous methodological refinement, whereby LCA developers and practitioners are operating through large networks of practitioners and working groups to capture the best available cross-cutting knowledge to improve the methodology. In contrast to the territorial scales useful for ES assessment applications, LCA is globally acknowledged to be an effective tool to support sustainable decision-making at the scales of “product” and “economic sector”. At these scales, the need for detailed technological information when building life cycle inventories is compensated by the interest of private (industry) actors of improving their environmental (and economic) good or service performance. The ES community could learn from the methodological harmonization process (for example in terms of guidelines and databases) occurred over the last 30 years in the field of LCA and its family of related life cycle approaches (e.g. life cycle costing, carbon footprint, water footprint, environmentally-extended input-output analysis, etc.), as well as from the various on-going initiatives devoted to bring more consensus among the variants of, or the complementary methods for, LCA (e.g. consequential Vs. attributional LCA, territorial LCA, organizational LCA, social LCA, etc.). In turn, the LCA community could make a step forward to better incorporate ES knowledge in the modelling framework for life cycle inventory and impact assessment, without necessarily denaturizing its role of environmental accounting methodology for products analysis and comparison. Moreover, encompassing the higher assessment granularity of the ES approach could be useful to improve current LCA effort to addressing territorial challenges, where functional units are not necessarily products or economic sectors but urban and regional systems. This mutual effort can bring to an integrated approach that takes full advantage of win-win research developments in the ES and LCA communities. Two strongly linked thematic areas have been identified that may allow cross-fertilizations between state-of-the-art practices, methods and tools in and outside practice, whose interaction and operationalization for an integrated “ES–LCA” based framework can contribute addressing the abovementioned challenges of incorporating ES values, trade-offs and impacts in public and private decision-making:
