Sustainable public procurement (SPP) is the act of purchasing products and services with the lowest environmental and highest positive social impacts, throughout the life-cycle of products and services. [1][3] This includes considering a wide range of characteristics of the products and services procured, such as: the use of non-toxic substances, renewable materials, energy and water consumption during use, as well as disposal, reuse and recycling options at the end of life.
This Solution is tailored to Local Governments who have ownership and/or regulatory authority over the municipal water supply system. In this Solution, the Local Government takes a comprehensive approach to increase its energy-efficiency throughout the different phases of the system`s project and useful life, from policy setting, planning, project design, and project evaluation to operation, maintenance and monitoring.
Waste incineration with energy recovery, usually named Waste-to-Energy (WtE) is a widely applied technique in developed countries – especially in the European Union, Japan, and the USA. WtE plants process the Municipal Solid Waste (MSW) and similar wastes that remains after waste prevention, re-use and recycling. WtE plants treat waste hygienically, reduce its volume by about 90%, and enable the recovery of energy contained in the waste through the generation of electricity and /or thermal energy (steam or hot water). The electricity is fed into the power grid to supply the end-users; depending on local infrastructure, the hot water can be used for District Energy network to heat (or cool) homes, hospitals, offices etc.; and the steam can be used by nearby industries for their production processes.
Local governments invest huge amounts of resources in providing urban transport infrastructure as a measure to combat the effects of rapid motorization and to ensure citizens’ access to work, markets and services. Nearly 75% of cities have direct control over their transit system, and 80% have control over roads [1].
Transit Oriented Development (TOD) is urban development that relies on public transport, while maintaining a closely knitted urban fabric through high-density, mixed land use and human-scale design, within walking distance from transit stations. Key features of TOD include: high-quality public spaces which are sensitive to community needs; variety of housing types and prices, frequent reliable, fast and comfortable transit; and measures discouraging the use of private cars, including walkable and cycling-friendly environment, parking management, traffic calming measures promoted through street design and others. TOD can create socially vibrant communities, contribute to economic development and enhance environmental quality. TOD is a key strategy for integrating land use and transportation planning and enabling sustainable urban mobility.
Urban freight and logistics looks at the movement of goods made by light or heavy vehicles, as well as non-motorized transportation modes such as cargo bikes and rickshaws. It can be linked to different market sectors such as retail, waste, construction, road services, hotel, restaurant and catering industry, as well as express courier and post. Globally, transport accounts for 23% of total GHG emissions, of which 40% is contributed by freight transport. Heavy freight vehicles are also one of the world’s major sources of Particulate Matter (PM) emissions, impacting urban life both directly and indirectly.
