The deliverable aims to provide an overview of various types of footprints and environmental impact indicators and then review existing personalized carbon and environmental footprint calculators in detail with a viewpoint to assess their suitability for use in I-CHANGE Living Labs (LLs). Additionally, the deliverable also discussed a few macro-scale modelling methodologies and simulation frameworks that can help assess the impacts of changed behavior on climate and the environment.

Environmental footprints and indicators to measure impacts are considered alternative methodologies to assess the impacts of human activities on the environment. The deliverable provided an overview of both of them in detail. With certain information collected from the I-CHANGE living labs about their activities, expertise, focus areas, tools and sensors used to collect data in the past and their planning during the I-CHANGE project, the preliminary proposition of related footprints and indicators for each living lab is developed. Because of the universal nature of Carbon footprint and also their wide availability and acceptance, the deliverable carried out an extensive review of existing open-access personalized carbon footprint calculators (in both forms as a smartphone app and web-based calculators). The Multi-criteria analysis approach is used to obtain the list of a few most suitable calculators that score best in all major criteria. The criteria used for their scoring are; 1) calculation basis (clear explanation of the calculation methodology), 2) consideration of a wide range of input categories (including transport, consumption patterns of food, goods and services, recycling behavior etc.), 3) Balancing of the questionnaire in terms of asking information that is readily available to the users, 4) Regional-global transferability of the tool, 5) output styles and strength of information, 5) user interaction/engagement consideration. High weightage is given to criteria 3 and 5 while performing the analysis because working with citizens in a living lab environment requires the use of tools that have these key features. Calculators that have been developed by government organizations are more robust and optimal to use in living labs (e.g. Sitra, WWF etc.). Apart from that Consumer footprint calculator is also discussed in detail as it provides output in terms of effects on impact category indicators. Within macro-scale assessment models, models related to personal mobility, energy consumption, air quality and climate change are discussed. A few selected models based on their relevance for the I-CHANGE project in each domain are discussed in detail along with their data requirements, outputs and their integration with each other to help analyze the translation of the effects of policy scenarios from one domain to another.

Within the deliverable, it is also attempted to link the content with tasks/activities of other work packages in the project. For example, the discussion carried out about carbon footprint calculators and their suitability directly supports task 4.4 of work package (WP) 4, where there is an intention to develop the project’s own carbon footprint calculator. Additionally, footprints and indicators mentioned in the 2 nd Chapter of the deliverable along with their mapping for each living lab are also an important output of this deliverable as it will pave way for designing data collection and citizen science activities within a living lab in such a manner that these footprint/indicators can be assessed. Together this will support various tasks in WP 2 and 3. Also, discussion of macro-scale models is mentioned in a manner that will provide support to tasks 3.1, 3.2 and 3.3 in WP 3.
