â¶ Urban planning should be integrated with the transport sector.In 2030, as a result of measures envisaged in the IPCC, such as changing mobility patterns, increasing electrification and renewable fuels, a share of 28% of renewable energy in transport-mobility is expected to be achieved, as well as a reduction in emissions of more than 30% in that same decade.The construction sector comprises the residential, commercial and institutional subsectors (for more details, see ANEXO C section C.3. Sustainable construction).Following the principle âfirst, energy efficiencyâ, the European Commission proposes energy efficiency in construction as the first of the blocks of measures to be taken.
