From Free Trade to Green Trade: The Changing Rules of Globalisation
For much of the twentieth century, international trade was shaped by tariffs, quotas, production costs, exchange rates and access to markets. Developing countries gradually entered global manufacturing through relatively inexpensive labour, natural resources and expanding industrial capacity. Small and medium enterprises became important suppliers of garments, leather products, engineering components, chemicals, agricultural commodities and consumer goods.
The globalisation wave of the 1990s and early 2000s encouraged countries to integrate into international production networks. Trade liberalisation reduced many traditional barriers, while global value chains allowed smaller producers to participate in international markets without controlling the entire production process.
However, the emerging global trading system is undergoing a fundamental transformation.
Market access is increasingly determined not only by what a firm produces, at what price and with what quality, but also by how the product is manufactured, how much carbon is emitted, where raw materials originate, how environmental impacts are measured and whether the entire production process can be independently verified.
This transition reflects a legitimate global concern. Climate change, resource depletion, pollution and biodiversity loss have created strong economic and environmental reasons for changing industrial production.
Yet an important question remains largely unresolved.
Will green trade create a more sustainable global economy, or will it unintentionally produce a new system of exclusion in which only financially and technologically capable enterprises can participate?
The answer may determine the future of millions of small producers across developing economies.
The New Invisible Trade Barrier: The Cost of Proving Sustainability
Traditional trade barriers were relatively visible. Import duties could be calculated, quotas were announced, and technical specifications were generally documented.
The emerging green trade regime is more complicated.
A manufacturer may produce a relatively low-emission product but still lose an export order because it cannot provide internationally acceptable carbon-accounting records. A textile exporter may use environmentally responsible production methods but lack the documentation required by an international buyer. A small engineering enterprise may comply with domestic pollution-control requirements yet be unable to finance independent environmental verification.
The distinction between environmental performance and environmental certification is becoming economically significant.
A firm must increasingly demonstrate sustainability through measurement systems, digital records, testing laboratories, traceability platforms, environmental audits and third-party verification.
These requirements involve fixed costs that do not decline proportionately with enterprise size.
For a large multinational corporation, the cost of environmental reporting can be distributed across substantial production volumes and numerous export contracts.
For a small enterprise, similar requirements may consume a significant proportion of annual profits.
Consequently, the same environmental standard can create very different economic burdens.
The emerging danger is that international markets may reward the ability to document sustainability more immediately than the ability to achieve it.
This does not make environmental verification unnecessary. It reveals a fundamental weakness in how compliance obligations and their costs are distributed.
Carbon Accounting: A New Currency of International Competitiveness
Carbon accounting is becoming an important element of industrial competitiveness.
The European Union's Carbon Border Adjustment Mechanism, or CBAM, illustrates this transition. Its definitive regime began in 2026, following a transitional reporting phase. It initially covers selected carbon-intensive goods, including iron and steel, aluminium, cement, fertilisers, electricity and hydrogen.
The mechanism is intended to reduce carbon leakage and align the carbon costs of covered imports more closely with those faced by European producers.
Its environmental rationale is understandable. Without appropriate safeguards, carbon-intensive production could shift to jurisdictions with weaker climate policies.
However, its economic consequences extend beyond the price of carbon.
Producers and importers need reliable emissions information, appropriate calculation methods and supporting documentation. Depending on the applicable rules, insufficient verified information can increase compliance difficulties or lead to less favourable emissions assumptions.
Large enterprises generally have better access to environmental consultants, measurement technology, accredited verification services and dedicated compliance departments.
Smaller firms may struggle even to establish their baseline emissions.
Consider two hypothetical engineering suppliers.
One is a large company with sophisticated energy-monitoring systems, environmental management software and established international certification arrangements.
The other is a small foundry operating in an industrial cluster, purchasing electricity from the grid and using conventional production equipment.
The smaller enterprise may have genuine opportunities to reduce energy consumption and emissions. However, without measurement equipment, technical assistance and affordable verification, it may be unable to demonstrate those improvements to international buyers.
The problem is therefore not simply the environmental standard itself.
It is the unequal institutional capacity to respond to that standard.
Carbon accounting could become a new form of economic infrastructure, as important to future trade participation as electricity, transportation, telecommunications and banking.
Countries that fail to build this infrastructure risk excluding otherwise competitive enterprises from international markets.
The Sustainability Paradox: Green Production Without Green Market Access
A particularly troubling possibility is that environmentally responsible producers may be excluded because their sustainability cannot be documented.
Many developing-country enterprises already practise forms of resource efficiency through economic necessity.
They repair machinery rather than replace it, reuse materials, minimise wastage, employ labour-intensive production techniques and operate within local supply networks.
These practices do not automatically mean that their products have lower life-cycle emissions. Inefficient equipment, fossil-fuel electricity and poor waste treatment can offset some advantages.
Nevertheless, traditional production systems may contain genuine environmental strengths that standardised reporting systems fail to recognise adequately.
Consider a small handloom enterprise producing textiles with relatively little direct mechanised energy use. Its environmental footprint may compare favourably with some industrial alternatives, depending on fibre sourcing, dyeing, transportation and other life-cycle factors.
Yet the enterprise may lack documented energy data, chemical traceability, recognised certification and product-level environmental assessments.
An international buyer might consequently prefer a larger factory with sophisticated reporting systems, even when the actual environmental comparison is uncertain.
This creates a dangerous possibility.
Green trade may unintentionally replace the principle of environmentally responsible production with the commercial requirement of being an environmentally documented producer.
The two objectives should reinforce each other. They should not become substitutes.
The Hidden Economics of Green Compliance: Why Small Firms Pay More
Environmental compliance involves more than purchasing cleaner machinery.
Its economic structure includes several layers of expenditure.
A firm may need to establish emissions baselines, identify upstream suppliers, maintain digital traceability records, undertake laboratory testing, train employees, commission audits and renew certifications periodically.
Many of these expenses are fixed or recurring, irrespective of export volume.
An illustrative calculation demonstrates the problem.
Suppose environmental measurement, documentation and verification cost an enterprise ₹5 lakh annually.
For a company exporting goods worth ₹50 crore, this represents only 0.1% of export turnover.
For a small enterprise exporting ₹50 lakh, the same expenditure represents 10% of turnover.
The figures are hypothetical, but they reveal the structural disadvantage created by fixed compliance costs.
| Illustrative enterprise | Annual exports | Compliance cost | Share of exports |
| ----------------------- | -------------- | --------------- | ---------------- |
| Large exporter | ₹50 crore | ₹5 lakh | 0.1% |
| Small exporter | ₹50 lakh | ₹5 lakh | 10.0% |
In practice, compliance costs differ by sector, certification scope, buyer requirements and company size. Nevertheless, the underlying economic problem remains.
A requirement that appears neutral on paper can become discriminatory in its economic effects.
This is especially important for enterprises operating on narrow margins.
If buyers refuse to compensate suppliers for additional environmental documentation, compliance costs are effectively transferred down the value chain.
Large international brands may strengthen their sustainability credentials while smaller suppliers bear a disproportionate share of the expenditure.
The resulting inequality is not merely between developed and developing countries. It also exists between multinational buyers and domestic suppliers, large exporters and microenterprises, and formal manufacturers and informal production networks.
Green Protectionism or Genuine Environmental Responsibility?
The relationship between environmental regulation and international trade requires careful interpretation.
Not every environmental standard is a disguised trade barrier.
Many regulations address real market failures. Carbon emissions impose costs on society that are not fully reflected in market prices. Pollution damages health and ecosystems. Unsustainable resource extraction can destroy future productive capacity.
Environmental regulation can therefore improve economic efficiency over the longer term.
However, legitimate environmental objectives do not automatically guarantee fair implementation.
A green trade requirement becomes particularly problematic when compliance systems are unnecessarily expensive, verification arrangements are concentrated among a small number of providers, reporting requirements overlap, or equivalent environmental outcomes achieved through different methods are not recognised.
Another concern is the growing influence of private sustainability standards.
International retailers, financial institutions and multinational corporations increasingly establish their own supplier requirements.
These may exceed legal obligations and differ across buyers.
An enterprise supplying three international customers could face three separate documentation systems, different audit arrangements and overlapping reporting obligations.
Such fragmentation increases transaction costs without necessarily producing equivalent environmental improvements.
This raises an important institutional question.
Who should determine the environmental conditions of international trade: governments, international institutions, independent standard-setting bodies or powerful multinational buyers?
If private market power increasingly determines compliance expectations, smaller suppliers may have limited opportunities to negotiate.
The result could be an emerging system of environmental governance in which the firms most affected have the least influence over the rules.
Developing Economies: The Risk of a New Global Sustainability Divide
The historical development of advanced industrial economies depended heavily on fossil fuels, resource-intensive manufacturing and expanding consumption.
Today, developing countries are being asked to industrialise under considerably stricter environmental expectations.
The need for climate action is real, and industrialising countries cannot ignore environmental damage. However, the financial and technological conditions under which countries are expected to decarbonise remain highly unequal.
Advanced economies generally possess stronger environmental institutions, more developed certification markets, greater access to affordable capital and better technical infrastructure.
Many developing economies face expensive financing, unreliable electricity, limited testing facilities and fragmented industrial production.
Consequently, the transition towards greener international trade could reinforce existing structural inequalities unless accompanied by substantial capacity-building.
The risk is particularly serious for countries whose exports depend on labour-intensive manufacturing and networks of small suppliers.
These countries may face a dual challenge.
First, they must improve the environmental performance of production.
Second, they must demonstrate that performance through internationally recognised systems.
The second challenge can be financially demanding even when the first is technically achievable.
Without adequate support, green trade could produce a new division of the world economy: countries capable of producing and verifying sustainability, and countries that remain outside premium markets because their verification systems are inadequate.
This would weaken both development opportunities and the global environmental transition.
Excluding small producers does not necessarily eliminate their emissions. It may simply redirect production towards less demanding markets.
India’s MSME Clusters: A Critical Test of Green Competitiveness
India's industrial structure makes this challenge especially important.
Thousands of manufacturing clusters support production in textiles, garments, leather, engineering goods, foundries, ceramics, chemicals, food processing, handicrafts and numerous other industries.
These clusters contain substantial productive capabilities, but many enterprises operate with limited financial resources and weak access to specialised technical services.
Historically, India's cluster development programmes have emphasised common infrastructure, technology upgrading, productivity improvement, skills, marketing and access to finance.
The next phase of industrial development will require another dimension: shared environmental intelligence and compliance capability.
A textile cluster in Tirupur, an engineering cluster in Ludhiana, a leather cluster in Kanpur or an industrial manufacturing cluster in Rajkot may face different environmental challenges.
However, they share a common institutional problem.
Individual small firms may be unable to finance sophisticated measurement and verification systems, while collective infrastructure could substantially reduce the cost per enterprise.
India therefore needs to reconsider environmental compliance as a cluster-level public and shared service rather than merely an individual enterprise obligation.
Common facilities could support emissions measurement, energy audits, environmental testing, digital traceability, technical training and preparation of documentation.
Cluster associations, technical institutions, accredited laboratories, financial institutions and export promotion organisations could participate in these systems.
This approach would not eliminate the need for firm-specific data or independent verification. It would reduce duplication and make reliable compliance more affordable.
The policy objective should be to convert environmental compliance from a barrier to entry into an instrument of industrial upgrading.
The Missing Link: Green Finance for the Smallest Producers
Much of the global discussion about green finance concentrates on renewable energy projects, electric mobility, hydrogen, large industrial decarbonisation investments and sustainable infrastructure.
These investments are important, but the financial needs of small enterprises are often different.
A small manufacturer may require relatively modest expenditure for energy-monitoring equipment, process improvements, cleaner boilers, water recycling, testing, certification or digital documentation.
The investment may be too small to attract specialised green finance and too risky for conventional lenders.
This creates a financing gap.
Environmental standards create demand for upgrading, but financial markets do not necessarily provide the resources required to comply.
The situation becomes more difficult when compliance expenditure does not immediately increase production or generate additional revenue.
A bank may finance a machine that expands output but hesitate to finance a carbon-accounting system that primarily protects future market access.
This distinction is crucial.
Green compliance finance should be recognised as a form of competitiveness finance.
Possible instruments include cluster-level credit facilities, concessional loans, partial guarantees, performance-linked grants and buyer-supported supplier upgrading.
Large international buyers could also share the costs of environmental transition through longer procurement commitments, technical assistance and transparent pricing arrangements.
Otherwise, sustainability requirements may become another mechanism through which powerful buyers transfer commercial risks to weaker suppliers.
Beyond Certification: Measuring Real Environmental Improvement
One of the greatest risks in the emerging green economy is the expansion of documentation without corresponding environmental transformation.
A factory may obtain multiple certificates while continuing to use inefficient machinery.
Another enterprise may substantially reduce energy consumption but fail to obtain recognition because it cannot afford an expensive audit.
Public policy should distinguish clearly between compliance expenditure and environmental performance.
Certification has value when it provides credible evidence. But the ultimate objective should be measurable reductions in emissions, pollution, water consumption, waste generation and resource intensity.
This requires a shift from certificate-centred incentives towards performance-centred systems.
For example, public support could prioritise verified improvements in energy efficiency, reductions in emissions per unit of output, cleaner production processes and better resource recovery.
Digital systems and appropriately designed common reporting frameworks could reduce repetitive paperwork.
However, digitalisation must not become another exclusion mechanism. Small enterprises need simple tools, affordable access and technical assistance.
Artificial intelligence may eventually reduce the cost of emissions estimation, document preparation and supplier data management.
Yet automated estimates cannot replace reliable measurements, appropriate methodologies and independent verification where these are required.
The future challenge is to make environmental information more accurate while making its production less expensive.
The 2035 Outlook: Three Possible Futures for Green Trade
The direction of green trade over the coming decade will depend on policy choices made today.
The first possibility is a fragmented green trading system. Major economies and international buyers develop increasingly different sustainability requirements. Firms face overlapping audits, incompatible data systems and costly verification. Large enterprises consolidate their market positions, while smaller suppliers are pushed towards less demanding markets.
The second possibility is a two-tier global production system. Advanced firms and countries gain access to premium green markets, sustainable finance and long-term procurement contracts. Smaller producers remain concentrated in low-margin markets with limited capacity to upgrade. Environmental performance improves in selected supply chains, but global industrial inequality increases.
The third possibility is an inclusive green industrial transformation. Governments, international institutions and private buyers invest in common measurement systems, mutual recognition, affordable verification, supplier development and transition finance. Small enterprises gain access to cleaner technology and credible environmental reporting without facing disproportionate transaction costs.
The third outcome is economically and environmentally preferable, but it will not emerge automatically.
It requires deliberate institutional reform.
International trade negotiations must increasingly address not only environmental standards themselves but also the affordability, accessibility and proportionality of compliance mechanisms.
Developing countries should participate actively in designing measurement methodologies and verification arrangements.
Technical assistance must move beyond occasional training programmes towards permanent environmental service infrastructure.
And international buyers must recognise that sustainable supply chains cannot be built through unilateral demands imposed on financially constrained suppliers.
A New Policy Framework: From Green Compliance to Green Inclusion
The future of sustainable trade requires a fundamental change in policy thinking.
Instead of asking only whether firms comply with environmental requirements, policymakers must also ask whether the compliance system enables genuine environmental improvement across the productive economy.
Five priorities deserve particular attention: internationally compatible reporting frameworks, proportional requirements for smaller enterprises, shared compliance infrastructure, accessible green finance and greater recognition of independently verified environmental performance.
India and other developing economies should treat these priorities as central elements of industrial and export strategy.
For India, the challenge is not simply to protect exporters from foreign environmental requirements. It is to create the institutional capacity through which millions of smaller producers can become competitive participants in a low-carbon global economy.
That requires linking cluster development, technology upgrading, export promotion, environmental governance and industrial finance.
Environmental transition cannot remain a separate policy compartment.
It must become part of mainstream economic development.
A Greener World Must Not Become a Smaller Trading World
The global movement towards sustainable production is necessary and increasingly unavoidable.
But sustainability cannot be judged only by the strictness of standards or the number of certificates issued.
Its success must also be measured by how widely cleaner technologies spread, how rapidly emissions decline and how effectively smaller producers are enabled to participate.
A global trading system that excludes millions of enterprises because they cannot afford environmental documentation may improve the reported sustainability of selected supply chains without achieving the broader transformation the planet requires.
The central economic contradiction is becoming clear.
The world wants cleaner production, but the cost of proving cleanliness may become a privilege available mainly to larger firms.
The next generation of trade policy must therefore address a question that traditional globalisation largely neglected: not merely who can produce competitively, but who can afford to demonstrate that competitiveness under increasingly complex international rules.
By 2035, environmental credibility may become as important as price, quality and delivery reliability in determining access to international markets.
The countries that succeed will not necessarily be those imposing the most elaborate environmental requirements. They may be those that build the most effective institutions for helping enterprises meet credible standards at reasonable cost.
The real objective of green trade should not be to reduce the number of firms allowed to participate in international markets. It should be to increase the number of firms capable of producing sustainably.
A sustainable global economy cannot be constructed by making environmental responsibility financially inaccessible.
The ultimate test of green globalisation will be whether it makes international production cleaner without making global trade more exclusive.
