Chapter I, dedicated to the sustainability of the energy model, includes the main applicable principles in the matter, that is, the guarantee of security of supply, economic efficiency and respect for the environment, as well as the national objectives for 2020 on savings and energy efficiency and on the use of renewable energies, consistent with those established in the European Union and from which an energy model is derived which, through the planning instruments provided for in the Law itself, will seek to increase the participation of renewable energies, reinforce the predictability and efficiency of energy policy decisions and especially of the incentive framework and reduce the participation of energies with the greatest potential for CO emissions. On the other hand, cooperation between Public Administrations is promoted, within the framework of the Energy Sector Conference, and research, development and innovation in the field of renewable energies and energy saving and efficiency are promoted, with special attention to new obligations for Public Administrations. Measures are adopted so that the information reaches the users and that they can know the costs of the energy supply model and its composition. Chapter II attributes to the Government the task of promoting the necessary actions so that our country fulfills its part of the objective assumed by the European Union on the reduction of greenhouse gases. To this end, the increase in the absorption capacity by sinks is promoted, in particular, those linked to forest use, the voluntary compensation of CO emissions, in sectors that must reduce them and are not subject to emission rights trading and, also, the constitution of a public fund to acquire carbon credits, obtained by Spanish companies and to boost their activity in sectors associated with the fight against climate change, also improving the tax regime for deduction of expenses made in investments destined for the environmental Protection. Chapter III decisively promotes the transformation of the transport sector to increase its economic and environmental efficiency and its competitiveness.
