• Current Scenario of Green Management in industry

Yale Center for Environmental Law & Policy and Columbia University Center for International Earth Science Information Network in collaboration with the World Economic Forum developed method of quantifying and numerically marking the environmental performance of a state's policies was introduced by Environmental Performance Index (EPI).

It measures the effectiveness of national Enviromental protection efforts by past iterations and strategies applied by that nation. Ranking given to only those countries of which Enviromental performance are measured. EPI was started with the measure of twenty three countries in 2002 now in the year of 2012 it reached to 132 countries and now in 2014 and 2016 EPI measure for 178 countries. The main objectives of EPI measure is Environmental Health and Ecosystem Vitality.

Developing economies, including China, India and Russia have had modest development over the past decade, but they have also paid an environmental price for their rapid growth. India is the fastest growing economy that ranks at in 2012 it is 125/132, in 2014 it is 155/178 now it’s in 2016 it is 141/178 EPI, which is worst rank. It is mainly due to Air Quality, Biodiversity and habitat protection.

Trends in Green Supply Chain

• Opinions of industrial Experts:

Prabhat Tripathi- SCM, Procurement, Logistics- 25+ years of experience Sarda Metals and Alloys Ltd-AGM-Logistics

1. Currently, Scenario is bleak and needs more awareness in terms of effect of pollution on environment and day to day activities.

2. Current SCOR model and ratios need to evaluate the procurement, manufacturing, storage and transportation activities in terms of environmental impact.

3. Green logistics should be adopted with focus on reverse flow of material for segregation and repair/refurbishing.

4. Subsidies and tax benefits to be provided for eco friendly industries.

5. Ecological disaster management to be taken as separate discipline and adopted in industrial safety methods.

Sumit Prakash- SCM- 15+ years of experience- State Supply Chain Advisor

Its really in a very poor state in India, actually SCM itself is not recognized everywhere and GSCM is the second stage.

Joseph Gbao From Sierra Leone-10+ Years - Procurement- Operations Manager at IsraAID

More Proactiveness is required

PARAMJEET SINGH-PRISM CEMENT LTD- 12- MARKETING,LOGISTICS

A supply chain includes product design, material procurement and selection, manufacturing operation, logistics till end consumer with support of top management and under burden of government legalization to make green environmental process. It is very important to take extra knowledge and consent for GSCM. need to be give full information to each every person.

Rathnakumar Vijayarajan-Cygnus Servlinks – Director-19 yrs. Of experience- Complete SCM, Procurement, Manufacturing,

Green in SCM? How we are going to make Green?

Ameya Pawar -Gep worldwide- Sourcing analyst-1 year- Procurement

"GSCM is a mandatory system now a days. GSCM is directly related to human health aspects. If you are running an organization with the help of GSCM, then probably you will save lot of cost also. One more thing I feel is that, govt. should support entrepreneurs who are applying GSCM in their organization. Govt. can provide different types of subsidies to empower them and make the implementation a bit easy.“ Green supply chain management is slowly taking initiative in many organizations. Still a big green SCM revolution is required mainly in manufacturing industry.

Sukesh K Gupta-Lamet Pharma Pvt Ltd-21 plus Years-Sales, Marketing and Logistics

"Initiatives to adopt GSCM in India is at large, Awareness programs should be taken by government; to make everybody aware benefits of GSCM. Also SCM sector should take initiatives to adopt GSCM which will become a major contributor in

i. Cost Reduction, ii. Pollution Control thereby reducing environmental constraints due to Global Warming. iii. Corporate Social Responsibility. iv. Evolving Consumer and Client Demand. v. Response to Increasing Fuel Price.

• To implement GSCM what we require to perform is P = S*E*A (P = Performance; S = Support, E = Efforts and A = Attitude.)

• Performance is like a SEA, wherein if proper support is there automatically Attitude changes and also proper efforts are put in.”

RC Srivastava-Last Mile Logistics- Partner ( before Gillette/Bajaj)-+30 yrs.-Logistics, warehousing, Sales back-end operations

At present we are using conventional transport & cost driven manufacturing bases may be at the cost environmental needs. This whole area has to be taken on top most priority. Threat to human life can be drastically reduced.

Dhongade Abhinaya Arvind - Custom Capsules Pvt Ltd-22 yrs.- Purchase and Logistics

The GSCM emphasizes upon the application of Supply Chain Management and adding the `Green ` component to it so as to stress upon the need of environment friendly systems. The growing importance of GSCM is driven mainly by the escalating deterioration of environment. The waste and emissions caused by the supply chain have become one of the main sources of serious environmental problems including global warming and acid rain. One of the key aspects to green supply chains is to improve both economic and environmental performance simultaneously throughout the chains by establishing long-term buyer–supplier relationships. Efforts need to make to study the supply chain of the systems with the focus on its optimization and implementation.

Jaspreet Singh Chadha-Infor India Pvt Ltd. / Sr. Consultant - Supply Chain Execution- 10 years- SCM, Logistics

Critical Parameters of Efficient Green Supply Chain will be Sustainability Risk Mitigation, Operational Alignment, Partner Development, Metrics and Measurement. Organizations need to have sustainability strategy for carbon footprint optimization that can be achieved with Carbon Measurement and Carbon Monitoring on regular basis. Green Supply Chain is all about Asses, Reduce, Re-use and Replace. Think Organizations need to start taking required steps towards achieving GSCM, as it is going to be continuous process of change to be incorporated at different levels while carbon monitoring.

Gautam Pawan-Jubilant – Buyer- 4.5 year-Scm and procurement

As a buyer, we have to check manufacturing process, reliability of products, transportation with vendor management, development from raw materials, Reverse logistics which all are directly related to company management.

Reinaldo Miliani- Supply Chain Professional worked in multinational chemical and pharmaceuticals companies like Novartis, DuPont, Sanofi and Boehringer Ingelheim.- 16 years

"Green supply chain involves a mindset change, that apart of the needs to be included within operative & logistics managers, should come in cascade from top

management to push or stimulate it, in the end, coming from a honest practical of corporate value (many multinational companies have it on their corporate core

values). I have noticed that in Supply Chain Education, as an example, from Apics, it is already included, which is really good. Of course, consider that I have worked in

Latin America, and, since we belong to developing countries, green supply chain must be experience. It is a culture mindset change which, with the proper education

and training, will be learnt over time. Kind Regards, Reinaldo Miliani”

Prashant S- Operations and Business Development Executive- 3

Currently, most of the companies are adopting green supply chain management in order to maximize supply chain surplus, government regulations and tax saving.

But, the focus should be shifted towards the effective usage of resources by proper analysis and execution with efficient supply chain network.

Sunil Prabha- Tata consultancy services -supply chain consultant- 12 –

Infrastructure and operational efficiency a big challenge for green supply chain management

PRABHAT TRIPATHI- SARDA METALS AND ALLOYS LTD- 26 Yrs.

Current GSCM is highly critical. Industry needs several incentives for adopting GSCM. Also legislative measures need to be implemented in a pragmatic manner.

Greening the Supply Chain also requires a thorough awareness and adoption of sustainability measures at each level.

Stefan van Leeuwen- Strategical Purchaser Mechanics at Panalytical- 30 years

We are one of the leaders in implementing "green"

Suresh Kumar D- Logisure Udan Pvt Ltd,- Operations -Head, Bangalore- 25

The awareness about this has to be done on a more number of platforms

Alvis Lazarus- Chief Executive Officer, Hesol Consulting- 15 Years

Good initiative

Dr P Venkataraman- GM - Logistics & Warehouse- 26 yrs.

It requires lot of efforts from one and all. Awareness to be created at all levels. It is like a cultural change. It should be made mandatory by Government and

Top Management / corporates involvement should be 100% there to improve GSCM scenarios. More schemes and helping hand should come from Govt.

The focus should be shifted towards proper utilization of resources with effective SCM practices.

Mitchell- Innovative Safe Solutions llc - Principle – consulting- 30 yrs.Since these are systems parameters, each solution will have its own set of relative values, highly successful learning systems, for example, may not need to

be high scoring in certain critical areas, because they will learn the importance as they operate. Decisions take into account the capabilities of the

organization, the potential solution options, the methods of evolving from condition a to condition b, with this in mind, picking critical criteria without a

specific system in mind is, from my perspective, "putting the cart before the horse." Having a list of criteria to consider, and investigating how the criteria fit

into a specific solution is valuable.

Pradeep Chechani- Independent, Retail, Operations- 20 yearsLot of ground to cover

P G Krishnan Iyer- Institute of Business Studies & Research- 30 yearsTeething troubles and awareness are still major issue

G.M. Kiran Kumar- 10 yearsCollaboration and analytics on this area gives vital improvements.

Bhausaheb patil- Autoline Industries Ltd- GM Manufacturing Excellence & TPM leader - 21 Need more focus on GSCM by

manufacturing industries.

Sreekanth Narayan- Yash Technologies, Sr. SAP SD Consultant, ERP- 14 yrs.It’s good to support nature and ensure this should be followed with zero tolerance

Vishnu Rayapeddi- NZPICS- 30+Still in the early stages, a lot more can be done and needs to be done.
