The transport sector represents 59% of GHG emissions, according to data from 2017. For this reason, the National Mobility Strategy is prepared with the aim of reducing emissions and respecting the hierarchy in the prioritization of transport systems established in Law 21/2018, of September 13, promoting the energy transition and climate change: firstly, favoring public transport and promoting non-motorized or assisted mobility; secondly, promoting electric motorized mobility or from a low GHG emission source. One of the tools for promoting the energy transition and climate change is the e²n National energy strategy and the fight against climate change. This Strategy includes different programs for mitigation, adaptation, training, innovation and technology, education and awareness, etc. and defines a more ambitious objective than the Law in terms of reduction commitment, since it includes the goal of climate neutrality for the year 2050, as Andorra has already advanced in the preparation of COP 25 and as contemplated in the update of the NDC of this year 2020. Unanimous approval in Parliament of Law ACCX 21/2018, of September 13, promoting the energy transition and climate change 13 and deployment of the corresponding regulations. The 2018 Law included in the legal text as an objective the reduction of emissions to the commitment levels of the first NDC of Andorra (-37% of the emissions not absorbed by the year 2030 with respect to the BAU scenario), and specifically specific measures for the different subsectors in the field of mitigation and adaptation.
