Sustainable consumption and production

It is no secret to anyone living in Beirut or a similar modern city in a semi-arid tropical country in the summer that their home has become a concrete forest and an urban heat island. Old wood or stone houses and their gardens have been replaced by concrete towers and parking lots, in the name of development. The result is searing summer nights, a drastic loss of insect and avian biodiversity, and a large increase in energy usage for interior climate control. These problems are experienced in rapidly developing urban centers worldwide. Moreover, cities worldwide are struggling with waste disposal. Roof gardens can help solve both problems highlighting synergies with a number of SDGs, including 7 and 11.
This collection of articles from the Editors of Environment International Journal explore the impact of climate change on health. The collection demonstrates the interconnectedness of SDG 13 and SDG 3. Understanding the changes and associated impact allows us to develop appropriate adaptive policies and practices to respond to climate-sensitive health risks.
SDG 7 sets the ambition to ensure access to modern energy for all by 2030, however this leaves significant procedural questions unaddressed. This paper argues that the basic orientation of this approach is problematic, undermining possibilities for progress toward energy justice and equitable development. Using a case study of Sierra Leonean rural cooking energy policy, this paper demonstrates how the underlying mentality of SDG7 feeds into existing discourses that marginalise producers and users of 'traditional' energy sources, threatening important livelihoods.

The need for better conversion technologies is a driving force behind many recent developments in materials. Second generation solar cells are based on thin films of materials, as compound semiconductor absorber layers. The thin film technology has a high potential, but research is needed to raise the device efficiency to such levels that cost of delivered power can be reduced. The paper by Siebenttritt recent developments which made thin film solar cells based on the chalcopyrite-type compounds Cu(In,Ga)(S,Se)2 [(CIGS) or (CIS)], promising materials which could significantly contribute as thin-film materials to the future share of photovoltaics in the supply of electrical power.
The article summarises research conducted in different climate zones related to green roof design that is correlated with roles of substrate in promoting plant growth. From the review, it will serve as a guideline for selection of substrate suitable for green roofs in different climates worldwide. From the recommendation made, the success of plant growth in addressing food security needs a concerted effort worldwide through development of standard guidelines related to green roof design for close comparison across the world region. The review supports SDG 11: Sustainable cities and communities, SDG 17: Partnerships for the goals and SDG 13: Climate action.
This study has investigated how smallholder farmers contribute to our global food supply. They looked at where farms are located, what type of commodities are produced (plants, livestock’s or fish) from farms of different sizes and their nutrition implications. They found that small farms produce 75–100% of all cereal in North America and South America, Australia, and New Zealand , livestock, and fruit in these regions, whereas small farms (<20 ha) found in sub-Saharan Africa, South Asia, southeast Asia, and China produce 75% of food commodities globally. This is in line with the attainment of SDG 2.
The study addresses how food production can continue using reduced water whilst at the same time bring about improved health. The growing population in India will have an impact on water availability to be used in agriculture and so the study looks at dietary patterns which use less water. They find important synergies in diets with lower water use and positive health effects. This is in-line with the achievement of SDG 2, its related targets and to a further extent SDG 6.

Hybrid perovskites are key to any discussion of materials for solar energy conversion. These organic-inorganic semiconductors (e. g. methyl ammonium lead iodide), which adopt the perovskite crystal structure, have perturbed the landscape of photovoltaic research. Highly efficient solar cells based on hybrid perovskite absorber layers can be fabricated by solution processed active layers. These materials are abundant and the simple processing could make high-throughput and low cost manufacturing at large scale possible. Exploring the materials that are viable in solar energy conversion contributes to advancing SDG 7.

In 2013 alone nearly 50 million tons of e-waste was generated worldwide. The United Nations’ STEP initiative has reported that e-waste is expected to grow by 33% over the next 4 years and by 2030 obsolete computer waste will reach 1,000 million tons. This electronic waste often contain toxic substances and nearly 80–85% of electronic products are directly disposed of in landfills or incinerators. The researchers suggest a new technique where circuit boards from electronics can be crushed into nanodust by a cryo-mill. The dust can then be easily separated into its component elements for recycling. The researchers intend it to replace the current process of e-waste into landfills and advances SDG 12.

In France the goal is to reduce greenhouse gas emissions by 25% by 2050. To support this, there are ambitious targets for the development of photovoltaic energy: 500 MW of new installations per year at a constant rate. Following a consultation with the stakeholders from the photovoltaic sector, a new regulatory framework for solar energy, set out in this detailed practice note, has been implemented which provides two distinct mechanisms depending on the type of installation. Solar energy is critical to SDG 7.2 to increase substantially the share of renewable energy in the global energy mix.
