As there is enormous release of co₂ in the world by means of pollutions and harmful gases an effective use of these gases should be done .The emphasis is on the dissemination of leading-edge research from basic science to the development of new processes, technologies and applications. This includes CO₂ as a feedstock in the chemical, energy and materials sectors, and utilization in general to help minimize environmental impact.

This statistic displays the market size of the sustainable or green chemistry industry worldwide in 2015, with forecasted figures for 2016 to 2020. The global renewable chemicals market size in 2015 was some 51.7 billion U.S. dollars, and it is forecasted that by 2020 it will be some 85.6 billion U.S. dollars.

Waste utilisation and Re-use involves the collection of used and discarded materials processing these materials and making them into new products. It reduces the amount of waste that is thrown into the community dustbins thereby making the environment cleaner and the air fresher to breathe. The global waste management market size is expected to reach $530.0 billion by 2025 from $330.6 billion in 2017, growing at a CAGR of 6.0% from 2018 to 2025. Waste management is the process of treating solid wastes, and involves different solutions to recycle items.

Green catalysts are the catalysts which are eco-friendly , can be regenerated hence reused multiple times and thus minimise waste production during process. The phase transfer catalyst market is projected to grow from USD 960 million in 2018 to USD 1,232 million by 2023, at a Compound Annual Growth Rate (CAGR) of 5.1% during the forecast period from 2018 to 2023

Advances in artificial intelligence (AI) could be one of the solutions to solving major global environmental crises--from climate change to animal endangerment to disease containment--as projects in each of these areas are already underway. Business decision-makers working in environmental sustainability are optimistic about the power of AI, according to a 2018 report from Intel: 74% of the 200 professionals in this field surveyed agreed that AI will help solve long-standing environmental challenges. However, several challenges prevent AI from being the answer to all of our environmental problems. Top barriers to doing so included cost (33%) and regulatory approval (17%), the report found.

The concept of sustainable building incorporates and integrates a variety of strategies during the design, construction and operation of building projects. The use of green building materials and products represents one important strategy in the design of a building.Green building materials are composed of renewable, rather than nonrenewable resources. Green materials are environmentally responsible because impacts are considered over the life of the product (Spiegel and Meadows, 1999). Depending upon project-specific goals, an assessment of green materials may involve an evaluation of one or more of the criteria listed below.

Sustainable chemistry is a scientific concept that seeks to improve the efficiency with which natural resources are used to meet human needs for chemical products and services. Global green chemicals market size will grow by almost USD 50 billion during 2019-2023, at a CAGR close to 10%. In the last few years, toxic chemicals have been facing bans due to the generation of hazardous chemicals.

Green analytical chemistry is described as the 'use of analytical chemistry techniques and methodologies that reduce or eliminate solvents, reagents, preservatives, and other chemicals that are hazardous to human health or the environment. According to the report, global renewable chemical market was valued at over USD 49.22 billion in 2016, is expected to reach above USD 102.76 billion in 2022 and is anticipated to grow at a CAGR of slightly above 11.29% between 2017 and 2022.

As the World Economic Forum (2016) reports, over 30% of plastic packaging materials "leak" into the oceans and other natural systems. They attribute this leakage in part to inadequate plastics recycling. The Global Plastic Antioxidants Market Size is estimated to be USD 2.2 Billion in 2019 and is projected to Reach USD 2.8 Billion by 2024, at a CAGR of 5.0%.

The global micro and nano market  size is expected to reach USD 721.14 billion by 2025, according to a new report by Grand View Research, Inc., progressing at a CAGR of 4.0% during the forecast period. Increasing automotive production and subsequent rise in plastics consumption in automotive component fabrication because of regulatory policies pertaining to vehicular weight reduction and fuel efficiency will drive the plastic market over the forecast period. So the amount of problems that occurred due to micro and Nano plastic are to controlled or eradicated which can be done by green chemistry. So this session involves how green chemistry can solve issues in plastic.
