Sustainability is a long-term goal for our society to meet the needs of economic growth at its current speed with the least amount of impact on the environment. But it’s more than preserving the natural world and its fragile ecologies. It's about enabling growth and development of businesses and government entities so that all parts of society work in harmony to ensure that future generations have the natural resources needed to survive.

Sustainability is our society’s ability to exist and develop without depleting all of the natural resources needed to live in the future. Sustainable development supports this long-term goal with the implementation of systems, frameworks, and support from global, national, and local entities.

The concept of sustainability is built on the notion that natural resources on Earth are finite, so supporting sustainable practices helps maintain a balance between environment, economy, and equity [1]. It’s the movement and energy behind ensuring that Earth can continue to be liveable, all the while controlling and reducing resource depletion.

Why is sustainability important?

Sustainability is important for preserving our planet and natural resources like water and air. Building a sustainable future and cultivating sustainable ways of living will reduce pollution and protect habitats of plants and animals.

A key part of sustainability involves sustainable business practices and economic development, including green technology, eco-friendly supply chains, and more. When businesses and government follow sustainable sustainable practices, it creates a ripple effect on individuals and communities to decrease greenhouse gas emissions and fossil fuels. All of this contributes to a better quality of life.

Three pillars of sustainability

The three pillars of sustainability (environmental, economic, and social) can help us to pave a path toward a sustainable future.

Environmental sustainability: The principle of maintaining ecological integrity and ensuring that Earth’s environmental systems remain balanced as natural resources such as air, water, soil, forests, and animals are being consumed by humans.

Economic sustainability: The goal for humans on Earth to maintain independence and be able to get a job or acquire other resources to meet their needs. Economic systems must be in place and accessible to all.

Social sustainability: The principle of ensuring that basic human needs are attainable by all and that there are enough resources available to all within a community. Strong social systems can ensure healthy, happy communities whose human rights such as labor, health care, and equality are respected.

Generative artificial intelligence technology, which, with the help of deep learning applied to artificial neural networks, is taught specific skills, performing activities previously performed only by humans, is finding more and more new applications in various branches of the economy, in various types of business entities. Generative artificial intelligence technology helps in solving complex tasks that require processing large sets of data in a relatively short period of time, which is already far beyond human capabilities. Therefore, more and more new tools based on generative artificial intelligence technology are being created, which are engaged in solving specific tasks, in which a number of specific criteria are required to be met in order to create a precisely specified product, project, innovative solution, finding a solution to a complex problem, and so on. This type of complex problem solving includes the creation of new solutions for green technology and eco-innovation, which can be helpful in connection with the need to accelerate and increase the efficiency of carrying out the green transformation of the economy, including the green transformation of the energy sector based on, among other things, the development of renewable and emission-free energy sources. However, paradoxically, generative artificial intelligence technology performing certain outsourced tasks i.e. based on large data sets collected in data centers, using Big Data Analytics technological solutions consumes large amounts of electricity. In a situation where these large amounts of electricity are generated by burning fossil fuels through dirty combustion energy, the aforementioned new technological solutions increasingly categorized as Industry 5.0 are unfortunately not described as green, pro-climate, pro-environment, pro-environment, pro-environment, sustainable, pursuing sustainable development goals, etc. Accordingly, Big Data centers assisted by artificial intelligence technology should be developed to fit in with sustainability goals, not to generate high electricity consumption and/or to be powered by renewable and carbon-free energy sources. The aforementioned Big Data centers assisted by artificial intelligence technology should therefore be designed and built in such a way that power plants generating energy from renewable sources are also built next to them or above them if they are built underground, such as wind farms and/or photovoltaic panel installations or other power plants generating energy by other means but emission-free. In the future, these may also include a new generation of nuclear power plants generating energy from currently generated spent fuel waste from currently operating nuclear power plants operating on the basis of widespread traditional nuclear technologies. Besides, in the future, another solution for emission-free clean energy may be the use of a new generation of nuclear power based on cold fusion. In addition to the above, the technologies categorized as energy futures also include energy based on green hydrogen and new types of energy resources, which may be extracted from space. An effective combination of the above-mentioned technologies, i.e. green energy technologies and ICT and Industry 4.0/5.0 information technologies, may lead to the creation of AI-assisted Big Data green data centers.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

Is it only me, or others feel too that green technologies, in fact, lead to a dramatic increase in pollution (in general, not only CO2 or other favorite "polutant of the day")? If someone tells you: this car just got 20% cheaper, you would normally ask: "How much does it cost now?" But, if someone tells you: "This (overly expensive!) bag made of recycled paper is better than a plastic bag, I command you to use that from now on!" or "Electric cars are good for you and for the planet you must buy them (or we will outlaw any other cars)", "Sorting (stinky) trash at home will slow down melting of polar ice caps, stop climate changes and help cute and helples penguins", most people would just believe it, without giving it a second thought. Besides, who ever offered ANY proof of any such claims? So they obviously need not to be proven, right?

Please, in this discussion, do bring proofs for, or critically question, on widely claimed statements about the topics listed in the title.

I have a paper to be completed, and the title is "The Expansion of Bank Branches and Enterprises' green technology innovation: Evidence from China". Which journal is this paper suitable for?

In connection with the still high level of greenhouse gas emissions and the rapidly progressing process of global warming, in order to save a significant part of the planet's biosphere from annihilation and to ensure the possibility of life on the planet for future generations of people, it is necessary to effectively and efficiently carry out a green transformation of the economy, including carrying out a green transformation primarily of such sectors of the economy as the energy sector, agriculture, transport, construction and industrial and mining sectors. Besides, the key factors of green transformation of the economy also include increasing the scale of waste sorting and recycling, increasing the scale of implementation of sustainable development goals in individual spheres of civilisation development, increasing green areas in cities, and systemic reform of forestry consisting in changing deforestation processes into aforestation, increasing the scale of sustainability, restoration and protection of biodiversity in forest management. In order to effectively and efficiently carry out the green transformation of the energy sector, it is necessary to scale up the development of renewable and emission-free energy sources. In some countries, such as Poland, there is still an outdated energy system in which more than three quarters of heat and electricity is produced by dirty fossil fuel combustion energy. Such a high level of underdevelopment in the energy sector is the result of unused technological and financial opportunities, as well as mainly blocking and limiting the development of clean, emission-free renewable energy in the last 3 decades and especially in the last 8 years. Key factors for the limited sources of financing for the development of renewable and zero-carbon energy sources include, for example, the earmarking of funds obtained from the sale of CO2 emission rights for other purposes instead of supporting the green energy transition. As a result, the energy system, dominated by government-controlled SOEs, large mining, refining and energy companies, is characterised by low levels of investment in new green technologies and energy eco-innovations. Over the past 8 years, despite emerging technological and financial opportunities, energy companies have failed to make investments that would increase the level of flexibility in adapting energy transmission networks to changes in the level of energy production from different energy sources, including renewable and carbon-free energy sources. As a result of the lack of this type of investment, it is becoming increasingly common that when the level of sunshine is high and/or the level of wind power is high and/or the level of energy consumption by citizens is significantly reduced, there is a large unused surplus of energy. Technologically outdated power grids are unable to accommodate such large energy surpluses. The lack of a constructed storage system for the surplus energy produced results in large losses of generated electricity from renewable and emission-free energy sources. In addition, the government encouraged the development of prosumer energy by having citizens co-finance the creation of backyard mini-generation plants, i.e. mainly the installation of photovoltaic panels on the roof of residential houses. On the other hand, when prosumers, i.e. citizens, produce a significant surplus of electricity, the government-controlled electricity transmission grid companies do not accept this surplus electricity and therefore do not refinance the citizens' bills for the surplus electricity produced. In addition, in a situation of high levels of sunshine and wind power, i.e. where there is a large surplus of electricity generated, it is mainly renewable and emission-free energy sources that are excluded from the energy production system, and not dirty combustion energy sources emitting CO2 into the atmosphere. These are therefore very serious systemic errors in energy management by the government in Poland over recent years.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

As part of the rapid technological progress that is taking place, new technological solutions, innovations and patents are being developed for use in various sectors of the economy and are improving manufacturing, production and service processes. On the other hand, due to the progressing process of global warming, the growing scale of natural resources consumption, the necessity to accelerate the processes of achieving the goals of sustainable development, the processes of green transformation of the economy, achieving the goals of environmental and climate policy, increasing the scale of protection of the planet's biosphere, biodiversity and climate, the demand for new eco-innovations and green technologies is growing. In the situation of combining new information technologies and Industry 4.0 with eco-innovations and green technologies, new opportunities arise for the application of new integrated, complex technological solutions and for increasing the effectiveness of the implementation of sustainable development goals and carrying out processes of green transformation of the economy, including the green transformation of the energy sector. The green transformation of the energy sector is mainly implemented through the development of renewable and emission-free energy sources. In addition, as part of the implementation of the plan to create a zero-carbon economy, it is also necessary to carry out a green transformation of the transport sector and this in all transport segments, i.e. land, water and air transport. As part of the green transformation of the air transport sector, new technological solutions are being developed to enable the use of engines to power aircraft based on solar energy or generated by burning hydrogen in oxygen. The future of powering large transport, passenger and space aircraft is hydrogen power. On the other hand, increasingly large drones are also being built, which are currently powered by electric motors that draw on electricity stored in batteries that need to be recharged. However, this may change in the future. With the combination of new technologies already being developed and tested in aviation, it will be possible to build, for example, large personal drones powered by hydrogen engines and controlled by artificial intelligence, so that they can be flown using autonomous automatic control, i.e. autopilot. In a hydrogen-powered situation, these would also be fully zero-emission, pro-climate and pro-environmental aircraft that could fly at low altitudes. This would greatly facilitate local transport over non-long distances, both passenger and freight. Such improvements in local air transport would be particularly important in areas where there are no airports, where there is no well-developed second-hand network and where, at the same time, people live in settlements far from large cities, in remote villages and small towns and in areas of strict nature conservation without the possibility of using vehicles with combustion engines.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

Since space shuttles, which were already built several decades ago, flew to the planet's orbit and were powered by hydrogen-oxygen fuel, it should be technically possible to build passenger and cargo planes powered by hydrogen-oxygen jet engines.

With the urgent transition to a zero-carbon economy, there is growing pressure to extend the green transition to avionics as well, i.e. to build zero-emission, zero-greenhouse-gas-emitting aircraft, and hydrogen-oxygen jet engines are such a solution. In the future, as part of the zero-carbon economy, such technological solutions should become widespread, and thus the green transformation should also include the aviation sector. The question then arises, when will this happen? When will avionics also be pro-environmentally transformed as part of the pro-environmental transformation of the economy and reduction of CO2 emissions into the atmosphere?

In recent years, commercial banks have been providing financing in the form of loans for pro-environmental, pro-climate, green investment projects and/or for the development of sustainable economic activities. Such credit offerings by commercial banks are referred to as green loans. Since in recent years the issue of the climate crisis is becoming one of the key topics and influential factors vis-à-vis the future development of civilization, so the scale of pro-environmental and pro-climate awareness of citizens is growing. More and more companies and enterprises are adding to their missions and development strategies the issue of achieving certain sustainable development goals and implementing pro-environmental business ventures. More and more economic entities are complicit with their green business in the issue of carrying out a pro-environmental and pro-climate transformation of the classic growth, brown, linear economy of excess to a sustainable, green, zero-carbon zero-growth and closed-loop economy Commercial banks have been building and improving their credit risk management procedures for many years, in Poland since about the mid-1990s, including procedures for analyzing the creditworthiness of potential borrowers applying for a bank loan and analyzing the credit risk taken by the bank in the situation of granting a loan. However, the growing pro-environmental and pro-climate economic activities, green investments, green businesses, green finance, green credit is a relatively new issue in Poland. Pro-environmental and pro-climate business ventures have been developed in Poland for a short time and are still a small part of the overall economy. Pro-environmental and pro-climate transformation ventures in the energy sector, including primarily the development of renewable and emission-free energy sources, have been developing particularly slowly in Poland over the past few years. The policy of blocking the development of renewable and zero-emission energy sources and the small relative to the possibilities financial subsidies offered to citizens under government public assistance programs have led to a low scale of green energy transformation, a high share of dirty combustion energy in the energy source mix, a low level of energy security and a high scale of negative effects of the energy crisis in the country. As a result, commercial banks in recent years have begun to offer green loans, with the help of which borrowers implement pro-environmental, pro-climate, pro-environmental business ventures within the framework of their chosen new strategy and mission, according to which they conduct green business, pursue sustainable development goals and their business activities are characterized by pro-environmental corporate responsibility. In terms of banking credit risk management procedures, a particularly important issue is the measurement of risk, the analysis of individual impact factors, the probability of their occurrence, the scale of negative impact on the borrower's enterprise, the scale of impact on the finances of the business entity, etc. Considering the implementation of pro-environmental, pro-climate, green investment projects, banks should also take into account new risk categories related to the specifics of sustainability, pro-environmental, etc. of green business ventures and investment projects. When new green technologies and eco-innovations are applied to investment projects, new categories of operational and other risks emerge. Various categories of environmental risks may be taken into account and arising from the ongoing process of global warming and the various negative effects of climate change taking place, as well as increasing levels of environmental pollution, dwindling supplies of clean water, increasingly severe periods of drought, etc. Such new categories of risk in a situation of high levels may cause the bank to change its credit policy and no longer lend to certain types of business ventures. For example, in some countries, commercial banks avoid lending to tourist companies operating in the mountains, hotels, restaurants, companies operating ski lifts and ski slopes due to the falling scale of snowfall in the winter. On the other hand, the emergence of new risk categories can be an important factor in the changes made in the credit risk management process, including those relating to green lending activities.

One of the important factors limiting the development of solar energy may be the still existing lack of eco-innovations and green technologies for the utilization of used photovoltaic panels, implemented on an industrial scale. In many countries, many new photovoltaic panels are currently being installed on buildings. The current energy crisis may additionally accelerate the development of renewable and zero-emission energy sources. However, for a few, a dozen or a max. Several dozen years, millions, and globally billions of photovoltaic panels will be dismantled due to wear and tear and should be disposed of, not landfilled. This is an important issue taking into account the potential contamination of the natural environment with toxic substances contained in photovoltaic panels.

In view of the above, I would like to address the following question to the Distinguished Community of Researchers and Scientists:

If we take the Mediterranean, its not one distinct climate it varies greatly from east to west and north to south. The north is more temperate-like with rainfall more dispersed throughout the year while the south drier with more heavy rainy spells. This surely would have an impact on the way green roofs perform .

Nanoparticles made by green technology are far superior to those manufactured with physical and chemical methods based on various aspects.

Is there any green synthesized Commercial nanoparticle product available in the market?

We need to apply some latest prediction methods available in the literature for primary data prediction related to Green technology

Moreover, define green technology and green design in this perspective.

I have my latent variables and identified their measured variables/indicators/manifest/measure items based on previous researches eg.

Green technology

Measure items (only mentioned 2 here)

GT1 Substitution of local natural resources with waste products of construction processes

GT2 use of recycle materials

Do I really need to have measured scale for green technology? If no, is it possible to conduct confirmatory factor analysis along with SEM software?

 which one could provide more values? 

Examples of green technologies such as solar panels, water harvesting tank, energy efficiency features etc. Farming as in planting & growing vegetables.

Questionnaire required

Whether or not green technology has a positive role in promoting sustainable development

Need some research papers on enablers and drivers in implementation of green manufacturing

I would like to get a list of anticancer medicinal plants

does change of perception influence the usage of system from traditional to environmental friendly way?

sustainable technology acceptance

what factors can change the perception towards acceptance of new technology?

In a bid to avoid environmentally hazardous effluent discharges from the pulping process, benign solvents are best used. Ionic solvents present the best options at the moment consequently the search for ionic/green solvents for pulping of waste material such as rice husk.

I conduct qPCR to determine the number of genome-containing particles in an AAV preparation using SYBR green technology. We used AAV-GFP plasmid as standard, and make 5 serial dilution (1:5) and triplicate, started from 8.7E10 copies and so on. However, I didn’t get a decent amplification curve and its appear as a junk.

I used to do the same experiment 2 months before and I never face such problem. I try new reagents like SYBER green, DNase, enzyme buffer and primers, I was thinking maybe problem with reagents. But still face the same problem. Furthermore, I checked the concentration of my standard (AAV-GFP) by Nanodrop and it was okay. as for the serial dilution are concern, I make them very carefully, vortex and pipet up and down several times. I think my serial dilutions will be okay. To sum up, I didn’t find the exact cause of this junk amplification curves.

Here I attached the amplification curve, melt curve and raw data plot of my standard curve.

Any idea what might have caused this?

Thanks,

The general technologies used for CO2 removal are the absorption process, adsorption, cryogenics, hydrate and membrane based separation processes. the chemical absorption process requires large amounts of energy, whereas, the membrane process is only applicable at low pressure conditions. Cryogenics required very high energy requirement and hydrate separation required high pressure conditions for low quality natural gas. Therefore, every technology have its own drawbacks and benefits. So, what could be the potential applicable technology would be there to solve this highly important issue?

Sure, the use of ERP systems helps to facilitate manufacturing operations, supply chain management and enterprise solutions in general. And sure, streamlining supply chains could reflect in environmental benefits.

But what about the continuous development of new technologies for electronic devices such as digital cameras, HD recorders, sound systems, etc., yielding increasingly bigger data files? Digitization requires a certain degree of ‘data mirroring’ to decrease the risk of data losses which, in turn, implies a higher storage capacity. Obviously, you don't want your life memories to get lost due to a HDD that crashes? For sure, it will happen, since it’s lifetime is smaller than yours. The business of storage capacity production (USB Drives, Hard Disks, Network Attached Storage, Data Servers, etc.) is highly influenced by the developments of new technologies for these electronic devices. You can make use of ‘Cloud Services’ (read: storage capacity somewhere else in a huge datacentre)… You can install your own home server…

I am just wondering how we will end up… Will we keep on building new power consuming datacentres with gigantic energy demanding cooling systems? Is this sustainable? The original idea of digitization from a sustainability point of view to save paper consumption in order to save biomass resources; is it relevant?

Any comment/remark/discussion is appreciated.

What do you think about Green Technology introduced by Malaysia's Prime Minister , Dato Seri Mohd Najib Tun Abdul Razak under the Government Transformation Programme (GTP)? Positive and negative responds are appreciated.

Has anyone done work in quantifying the economic benefits of being able to switch fuel sources? (ie. not get stuck on Natural Gas and be able to switch to say biomass or something else if/when costs escalate).

There's obviously a benefit, what metrics would you use to evaluate it? Any suggestions are appreciated.

 The multifaceted environmental challenges of resource degradation and drawdown facing humanity in the twenty first century demand a holistic, "win-win" problem solving approach by adopting down-to-earth solutions for achieving sustainable development that would satisfy the triple bottom line of 3P (people, planet and prosperity) or TBL of 3E (environment, economy and equity). We are now discovering that not all environmental problems are solvable by conventional technological means and within foreseeable nonrenewable energy limits. Employing conventional "end-of-the pipe" pollution clean-up approaches, in many ways, we are offering "temporary bandage" to ecological/environmental wounds or playing a “shell game” with pollution, solving one problem only to create another. The emerging discipline of Ecological Engineering or Ecotechnology is a paradigm shift - a response to the growing need for engineering practice for human welfare while at the same time protecting the natural environment and restoring the "bodily functions" of nature to ensure sustained flow of ecosystem goods and services. By definition, Ecological Engineering is the design of sustainable ecosystems that integrate human society with its natural environment for the benefit of both. It evolves out of an overdue alliance between engineering and ecology. With its root in ecology, this field has now matured to the point where it needs to have a prescriptive—rather than just a descriptive role to play in restoring existing disturbed or degraded ecosystems as well as designing and developing new sustainable ecosystems.  Naturally, it offers an opportunity for an acid test of our ecological understanding.

Mother Nature has the awesome R&D laboratory of her own. She has invented time-tested and trusted algorithms, optimized structures, designs, processes, tools, techniques, means and measures that humans can only try to emulate and imitate, but hardly reach that level of optimization. Living organisms are all unique by some way or other, the structures of cellular organization, the architecture of biogenic structures and substances generate wonder! The lotus's surface, bee hive, spiders silk, jet propulsion in cuttle fish, biological batteries, bioluminescence, aerodynamics, hydrostatics, ultrasonics, are few among thousands of awe-inspiring things! Beyond individual levels some ecosystems also present before us exquisite examples of efficiency, sufficiency, resilience and innovation. Mother Nature naturally can be our "model, measure and mentor" in creating new inventions and solving problems that humanity is facing and struggling with. I invite some interesting and illuminating discussions that will be expected to last long...........

Dear all,

We are currently on a project to cast geopolymer concrete with seawater.

The materials we are using are Class F Fly Ash.

However we are facing some problems with the activator.

Seawater was used in 2 methods - (Wet and dry method)

Wet Method

1) seawater was used to produce N-based alkaline and SSL with 2.3 modules SSP. The SSP was mix in seawater before mixing both the SSL and N-based alkaline liquid.

Dry Method

2) Sc powder and SS powder was together with seawater to cast the concrete.

Problems faced:

1) Drastic drop of compressive strength compared to those specimen using normal water. (90 degree 24 hours curing in oven)

2) Slow setting.

I have read a comment by Alex Reggiani saying that we could use seawater for geopolymer concrete.

I have been trying to contact him, does anyone knows his email?

Have anybody tried some method in which surfactants, or polymer and any other molecule intended to cover surface of nanoparticles in environmentally friendly and economically acceptable way.

I am working with novel plants in which not any prior work has been published yet. There are few evidences and unpublished medicinal uses of these plants. The plants from the same genus' were found to have many medicinal values and traditional usage. I did in vivo anti-inflammatory activity and anti-bacterial activity for one plant, in vivo and in vitro anti-diabetic activity for the second one. Both exhibited good activity. I also did GC-MS analysis and docking studies of the compounds identified by GC-MS analysis. I submitted this work as paper to Journal of ethnopharmacology. The reviewer commented that it is good work but not the description of a traditional medicine and said could not accept it for their journal. I then uploaded it to Planta Medica. They also commented tat the concentrations were irrelevant. But i followed the standard protocols and concentrations for all. Could anyone suggest me which international journal with good impact factor would accept these kind of work?

I would like to know about the plant species that can be used for phytoremediation of Organochlorides (or specifically endusulfan)...
