Green Design Evaluation of Kindergarten Furniture
Kindergarten is an important place for children’s activities, learning, and life, and early childhood is a key basic period of life. In early childhood, young children’s organs and body tissues are not mature and have strong plasticity in various aspects such as personality, intelligence, and physical development. Green design is also known as environmental design and environmental awareness design.

Green Diesel Production by Hydrodeoxygenation
Non-renewable fossil fuels and the air pollution associated with their combustion have made it necessary to develop fuels that are environmentally friendly and produced from renewable sources. Vegetable oils are a renewable source widely used to produce biofuels due to their high energy density and similar chemical composition to petroleum derivatives, making them the perfect feedstock for biofuel production. Green diesel and other hydrocarbon biofuels, obtained by the catalytic deoxygenation of vegetable oils, represent a sustainable alternative to mineral diesel, as they have physico-chemical properties similar to derived oil fuels.

Green Goldmining
Green goldmining was proposed since goldmining has brought about hardship in local communities through pollution of water and air; lost grazing and agricultural land; the creation of unprotected mining pits; exploitation and depletion of natural resources; as well as forced eviction and relocation of communities without fair compensation. Environmental management accounting practices are suggested to facilitate greener goldmining processes.

Green Hydrogen
Increasingly stringent sustainability and decarbonization objectives drive investments in adopting environmentally friendly, low, and zero-carbon fuels. Hydrogen represents a unique zero-carbon energy carrier akin to electricity. Hydrogen is hailed as a carbon-neutral fuel of the future, particularly in the form of green hydrogen.

Green Hydrogen Economy in Southern Africa
Green hydrogen energy is significant in decarbonizing the entire hydrogen value chain network from its generation to the end-user sectors. It can help achieve the UN Sustainable Development Goals (SDGs), especially the UNSDG 7, and regional sustainability. Further, the public sector (especially governments) are recognized to have a pivotal role in hydrogen energy deployment because it can enhance or drive the transition from a fossil fuel-based economy to a green economy, especially if the hydrogen energy ploicies are clearly articulated or translated into hydrogen energy statute in each Southern African Development Communities (SADC) country. To ensure that communities and SADC nations appreciate the hydrogen energy economy, there is need to also communicate the benefits that come with green hydrogen, alongside the global pursuit to reduce GHG emissions that cause climate change.

Green Hydrogen in UK by 2030
Green hydrogen was first found in the UK by Robert Boyle in 1671 when he described ‘flammable air’. In 2022 Green hydrogen was prioritised by UK Government to replace fossil hydrogen and other carbon intensive fuels. Fossil hydrogen UK production then exceeded 1Mte/a, but this should fall significantly by 2030, overtaken by green hydrogen. The University of Birmingham revealed the first UK green hydrogen refueller in 2008 filling five hydrogen-fuel-cell-battery-electric-vehicles (HFCBEVs) for study and development by 50 PhD students in Chemical Engineering. This supplied 10 kg/day, much smaller than the 2021 ITM station now to deliver almost 600 kg/day at Tyseley.

Green Hydrogen Value Chain
The potential of H2 as a fuel with the highest energy density per unit mass makes it great for application in all sectors that require energy. H2 is produced from a wide range of resources using different raw materials, pathways, and technologies, including fossil fuels and renewable energy. The classical method consists of breaking or reforming fossil fuels as a profitable H2 production pathway for industrial use, which was estimated (globally) at 85 million tons in 2016 (more than 600 billion Nm3/year). Therefore, the energy value of H2 and the clean energy index were not the main factors to consider in its use at an industrial level. Industrial H2 was used for the production of fertilizers, petrochemical refining, metalworking, food processing, cooling of generators of power plant energy and semiconductor manufacturing.

Green Infrastructure in Spatial Planning
Adaptation to climate change is becoming one of the main paradigms for how cities function and develop. The significant role of green infrastructure (GI) as a tool for cities to adapt to climate change is increasingly emphasized among practitioners of spatial planning and in the research literature. Green infrastructure should be understood as "a strategically planned network of natural and semi-natural areas with other environmental features designed and managed to deliver a wide range of ecosystem services. It incorporates green spaces (or blue if aquatic ecosystems are concerned) and other physical features in terrestrial (including coastal) and marine areas".

Green Innovation (GI)
Green innovation (GI) is an essential measure to realize green growth. The value of GI on achieving sustainable development goals is increasingly recognized in recent years. Promoting GI is also the fundamental requirement of China’s 14th Five-Year Plan. Notwithstanding that the central government has put the sustainable development goals at the heart of policy-making, formulating several environmental policies, the overall efficiency of environmental governance does not meet expectations. The GI of manufacturing industries is insufficient, and the phenomenon of illegally discharging pollutants continues to repeat, making the effects of policies into question.
