a. In 2019, Dutch businesses, working alongside public authorities, knowledge institutes, and Natuur & Milieu, will undertake the "Climate-neutral Construction Site Challenge" in order to identify knowledge and experiences, opportunities and possible obstacles surrounding zero-emissions mobile machinery, in order to accelerate the growth and incorporation of zero-emissions mobile machinery and advance knowledge exchange and to facilitate public authorities in this transition. b. C. The national government will create framework conditions within the regulations to allow cities to steer toward green construction traffic and the use of zero-emissions construction machinery, for example by imposing a monitoring obligation for emissions and load factor. d. The national government will be committed to putting carbon dioxide labelling and standardisation of mobile machinery on the agenda of the European Commission. If the agreements above have not yet led to an expected reduction of carbon dioxide emissions by mobile machinery of 0.4 Mt by 2030 (to be determined in consultation with local and regional authorities), the national government will impose zero-emissions green construction traffic and the use of zero-emissions mobile machinery by 2026. The government will already begin the preparation of legislation to allow rapid introduction of a legal obligation to take place. Public authorities will take the initiative to include the use of ZE mobile machinery and the principles of the HND Green Deal in procurement processes, such as for construction works and landscaping activities. In this regard, the national government and other public authorities will aim to achieve agreements on the standardisation of invitations to tender for zero-emissions machinery. Agricultural machinery will be added to the Green Deal for Mobile Machinery (HND Green Deal). The national government will enable the relevant top sectors to develop autonomous vehicles, via crossovers before 2023, that carry out transport and field operations sources for precision applications and run on renewable energy sources. e.
