The carbon footprint is an indicator that serves to measure the environmental impact of different activities, both economic and of the people involved in carrying them out.
Having this tool is key as a diagnostic element, a starting point to establish recommendations for improvement and set new objectives to meet the challenges that exist at state, European and global level on climate change, air quality or energy efficiency.
To calculate the carbon footprint, which is expressed in tons of CO2 equivalent, the direct emissions of the activity and indirect emissions must be taken into account, which, depending on the case, can cover many aspects.
There are different standards and instruments for calculating them, at European and state level, and compensation strategies implemented by the states as part of their environmental policies to promote their reduction.
