Cities play a central role in the fight against climate change. It is estimated that between 70% and 80% of global carbon dioxide emissions originate in urban environments, as a result of the concentration of population, economic activity, mobility, energy consumption and waste management. This reality places cities at the heart of the problem, but also at the heart of the solution.
Cities, businesses and communities are key agents of climate change. The way territories plan their growth, manage resources and make strategic decisions has a direct impact on greenhouse gas emissions and on their capacity to adapt to climate-related risks. At the same time, urban areas offer the greatest potential to implement effective policies, innovative solutions and governance models oriented towards sustainability.
Energy planning, sustainable mobility, building efficiency, waste management and the integration of renewable energy sources are among the main levers through which cities can significantly reduce their carbon footprint. However, for these measures to be effective, reliable information, clear metrics and tools capable of analysing, monitoring and tracking environmental performance over time are essential.
One of the main challenges faced by municipalities and organisations is the ability to measure the impact of their decisions. Without structured and comparable data, it becomes difficult to define priorities, assess future scenarios or communicate results transparently to citizens, investors and regulatory bodies. Climate action increasingly requires an evidence-based approach supported by technology.
In this context, Mezzegra – Green Energy has developed the CARB4GREEN platform, a digital solution designed to support the analysis, monitoring and reporting of the carbon footprint of cities, communities and organisations. The platform was created to help understand urban metabolism and transform environmental data into clear, actionable indicators for decision-making.
CARB4GREEN enables the measurement of greenhouse gas emissions associated with different activities and territories, the creation of management dashboards to visualise environmental performance and the development of forward-looking analyses with reduction and business-as-usual scenarios. By integrating data, metrics and visualisation in a single tool, the platform supports climate policy planning and mitigation strategies based on evidence.
At a time when climate action has become a strategic priority, cities are emerging as key spaces for transformation. The combination of effective public policies, community engagement and robust technological solutions will be decisive in reducing emissions, increasing urban resilience and building more sustainable territories.
