The Metropolitan Action Plan (PAM) guides the actions of Barcelona’s metropolitan government for each term, outlining strategic objectives to direct initiatives. It is based on the Government Agreement established between the political forces in the metropolitan government. The PAM 2024-2027 has just been approved and will guide the actions of the Barcelona Metropolitan Area's government, setting the roadmap for each department in line with the delegated competencies from the member municipalities. It defines general objectives and desired outcomes. Approved on April 30th by the Metropolitan Council, the PAM 2024-2027 includes 38 programmatic objectives, one of which is "Promoting a digital and modern metropolis." This aims to turn the AMB into a digital and smart metropolis, becoming an international reference and adapting the digital transition to the needs and challenges the metropolitan territory will face in the next four years. To enhance efficiency, sustainability, and resilience, technology is increasingly incorporated into activities of large cities, leading to smart cities through innovations like big data, IoT, and Bluetooth. The rapid development of technologies such as generative AI, machine learning models, the metaverse using VR and AR, drones, and 5G/6G telecommunications opens new horizons for future smart cities, focusing on people's experiences and engagement at the center of innovations.

The LEAP of the City of Skopje stands as the premier strategic document for local environmental protection, planning, and management. It evaluates current environmental conditions and implements both short-term and long-term measures to address identified issues. LEAP 3 is rooted in inter-institutional and multi-level cooperation, applying to the City of Skopje and its neighboring municipalities. This collaboration is crucial for tackling numerous priority challenges, such as excessive urbanization, illegal waste dumping, inadequate waste segregation, the need for wastewater treatment, and low environmental awareness among citizens. Additional issues addressed include the limited use of renewable energy sources, insufficient energy efficiency in buildings, the need for enhanced human capacity and inspections, necessary changes to the protection regime of certain protected areas, and intense traffic. The objectives of LEAP 3 are centered on reducing pollution, developing healthy and safe environments, preventing environmental impacts on health, preserving natural values, promoting their sustainable use, raising environmental awareness, and establishing an efficient environmental management system for Skopje and its surrounding areas.

The policy document is based on the GR's strategic guidelines and places a particular focus on transport infrastructure. The document contains eight directives that outline what the Gothenburg region aims to do to achieve the main objective of "Sustainable growth with significantly reduced climate and environmental impact”, i.e.:
1. increase railway capacity;
2. improve accessibility and capacity for public transport in the contiguous urban area;
3. increase sea and railway capacity for freight transport;
4. enhance cycling infrastructure in continuous regional routes;
5. develop the transport system in harmony with people's living environments, biodiversity, and ecosystem services;
6. adapt the transport infrastructure to the effects of climate change;
7. stimulate innovations and new technologies to achieve a more transport-efficient society;
8. create conditions for behavioral changes.
The most important function of the strategic document is the broad support in the development process, where all municipalities have an active role in developing the document. The document itself has many application possibilities at local, regional, and national level.
