Netzero is a platform that offers destinations the following differentiating aspects: data verified in real time with blockchain, correlation between the indicators, biodiversity, supply, demand, socio-economic data, georeferences and the reuse, monitoring and integration of the physical (IOT) and digital sources of information.

A solution essentially composed of 6 key elements to generate 3 indicators:

• Digital twin: as a common work space based on the scientific method and representation of reality.
• Monitoring: sensors, lidar sensors, satellite, public fountains, networks.
• Traceability: the use of blockchain technology for the digital certification of processes and results.
• Load capacity: geospatial aspects, integrating scientific data, biodiversity, increase or decrease in biomass, level of wellbeing, congestion, mobility; and socio-economic aspects, supply, demand, employment, profitability.
• Vulnerability index: it shows the current and future impact of society, the destination and tourist activities due to climate change, demographic movements or natural disasters, among other key factors.
• Adaptation indicator: to new climate scenarios, to the implementation of new technologies, to policies and new sources of financing and therefore new markets or models.
• Earthlink: Carbon credit market for offsetting CO2 emissions.
• Calculation of organisation and events’ carbon footprints

The platform integrates the main usage guidelines and indicators related to the Smart Destinations project in order to provide a realistic deviation metric and obtain a constant overview of its effectiveness.

TrueSMART is the indispensable tool to efficiently manage the data collected in smart tourist destinations and to give traceability and visibility to the actions of Smart Cities and Smart Destinations.
