With the ever-increasing number of cars in cities, it is essential to find innovative and sustainable ways to address parking. Green parking in cities is an innovative concept that is becoming part of the modern urban environment and contributing to the creation of sustainable and green communities for the future. It aims to minimise the negative impacts of asphalt surfaces that are common in traditional car parks, but above all it is about the environment and human health. They provide many benefits for cities an...

In 2019, the Green Cities submitted the first proposal for the Green Norm. The Green Norm is a set of practical recommendations mainly for politicians, officials and urban development officials. Green cities introduce this norm as a critical strategy for competitiveness. More and more people are moving to big cities, so we must consider climate-neutral solutions as the municipalities set an example. The number of green and climate-neutral towns in Europe and Latvia has constantly been increasing over the last deca...

Climate change and the deteriorating state of the environment pose a serious threat to the European Union and the entire world. The Green Deal for Europe sets a potential goal of achieving climate neutrality by 2050. This agreement aims to promote a green economy, create sustainable industry and transport, and reduce pollution. The main intention is to turn climate and environmental challenges into opportunities and ensure that the transition is fair and inclusive. The European Commission supports EU Member States...

We present a study on the responses of plants from three functional groups: grasses, forbs, and legumes, deriving from a coal mining waste heap, to changes in environmental stress factors. The aim of this work is to identify plant responses to environmental stress resulting from the transfer of plants from the waste heap to the waste substrate and an extensive green roof with a thickness of 15 cm. After one year of growth, selected functional traits were analysed: including height, specific leaf area (SLA), and ch...

The continuous development of human society from a technical-economic point of view is closely related to the increase in energy consumption. However, this implies the rapid depletion of existing fossil fuels and an accelerated increase in global pollution. At the moment, to counteract these impediments, one of the most important sources that can be used for the purpose of energy production, without having a negative impact on the environment, is hydrogen. Due to the fact that, when mixed with air, hydrogen can ge...

With the rapid growth of the population and urbanization, the demand for industrial production has continued to increase, and industrial solid waste has become more and more abundant. Industrial solid waste mainly includes fly ashes, slags, tailings, red mud, bottom ashes and other wastes, which account for approximately 80% of the total waste produced on Earth. Industrial wastes generally contain various heavy metal components such as Pb, Zn, Cu, Cd, Cr, As, Ba and Mn. The low recycling rate of solid waste result...

Water and sediments in coastal areas interact at different scales, thus shaping the marine environment and providing physical habitat for ecosystems. Hence, the hydromorphological conditions represent a key aspect of aquatic ecosystems considered in the Water Framework Directive as supporting quality elements (alongside the physicochemical), which are expected to provide the boundary conditions for the biological quality elements. Any alteration in those can reshape the corresponding biological conditions at vario...

The challenges of economic growth in today's economy are to create optimistic cooperation between industries and the state, local authorities and to maintain sustainability by balancing economic, environmental and social interests. The transition to a circular economy is in many cases understood only as an unnecessary barrier rather than as a new business model. Production based on a linear "take, make, dispose" model is no longer feasible on the grounds of environmental degradation. The aim of the study is to dev...

Cemented paste backfill (CPB) is an engineering mixture of mine tailings, cement and water. Tailings can commonly contain sulphidic minerals. In this case, acid mine drainage (AMD) may occur due to the oxidation of sulphidic minerals present in the body of the CPB. In general, AMD lowers the pH of the medium and water environment and may cause heavy metal release. Therefore, AMD potential is an important parameter to be considered with regard to environmental aspect. Static tests are widely used to determine the A...

The Mediterranean basin is distinctly vulnerable to climate change and its associated effects. This vulnerability is noticeably observed in the southern Mediterranean territories, where a perceptible outcome of climate change is the increase of the average temperatures over time, accompanied by water scarcity due to reduced precipitation. Although recent technological advancements have achieved to mitigate to some extend climate change impacts, particularly in stabilizing temperatures and enhancing water resource ...

The impact pile driving method is widely used for the reinforced concrete piles and metal tubular piles with a large weight. Pile driving is a dynamic process: the energy of heavy hammer impact on the pile head is transmitted through the pile shaft and pile toe to the surrounding soil, exciting vibrations of the soils particles and propagation further to the ground. Propagation distance is increasing with driving depth. Impact borned waves must be taken into account during construction work near existing buildings...
