CCaLC is a carbon fooprinting tool that enables quick and easy estimations of the life cycle greenhouse gas emissions along the whole supply chains.

It provides a powerful tool for reducing and managing carbon footprints of products, processes or supply chains.

The methodological approach follows the internationally accepted life cycle methodology as defined by ISO 14044 and PAS 2050.

The tool is simple to use by non-experts and it comes with comprehensive databases, including the Ecoinvent database. User-defined databases can also be added.

  • Carbon footprinting

    The CCaLC tool calculates carbon footprints from 'cradle to grave'. It enables identification of carbon 'hot spots' and carbon reduction opportunities.

  • Water footprinting

    In addition to carbon footprints, CCaLC also incorporates water footprint calculations to take into account water scarcity in different countries.

  • Other environmental impacts

    CCaLC also calculates other environmental impacts to show how they may be affected by any changes in the carbon footprint. These include acidification, eutrophication, ozone layer depletion, photochemical (summer) smog and human toxicity.

  • Economic impacts

    CCaLC enables estimation of economic value added, to show the trade-offs between 'carbon added' and 'value added'. The cost of reducing carbon footprints can also be estimated.

  • Optimisation of carbon footprints

    CCaLC Optimiser enables identification of optimum low-carbon options at minimum costs.

  • Databases and Case studies

    A number of databases and case studies have been included in CCaLC which can be modified to suit the specific needs of the user. Databases include: materials, energy, transport, packaging and waste. Overall, there are over 5500 data items included in the databases. The case studies include chemicals and relate products, food and drink, bio-feedstocks, biofuels and packaging.
