Carbon Footprint Audit Trends Shaping Manufacturing in India and the UK Through 2027
If you are an Indian manufacturer exporting steel, aluminium, and cement to Europe, the carbon border is not coming; it’s already here. The definitive phase of EU CBAM is in operation, and India is expected to bear almost 18% of total CBAM costs, nearly double its share of EU import value in covered sectors [1]. This disproportionate exposure is due to blast furnace-based steel production and the absence of a domestic carbon pricing mechanism in India.
At the same time, the UK has legislated its own carbon border adjustment mechanism through the Finance Act 2026, with requirements taking effect from 1 January 2027. For manufacturers operating in India or the UK, a carbon footprint audit has become an essential part of doing business with European markets. It is no longer just a sustainability initiative but a key requirement for export compliance. The absence of adequate carbon emission data can result in manufacturers paying higher compliance costs, having to rely on default emission figures, and struggling to comply with the demands of European clients and regulatory agencies.
In this blog, we'll explore the new landscape, discuss the implications for manufacturers in India and the UK, and highlight priority ESG carbon reporting actions you should undertake.
Why Carbon Footprint Audits Are Becoming Strategic Business Tools
Manufacturers should no longer view carbon footprint audits as a compliance exercise alone. They provide valuable insights that support operational efficiency, cost optimisation, and long-term business resilience.
The comprehensive carbon footprint audit will provide you with precise information on the areas within the manufacturing process that result in high emission concentrations. This is achieved through two means. The first is regulatory compliance. The second is efficiency savings. Processes that are energy-intensive and have high carbon intensity are generally those with the greatest potential for reducing costs.
Those who view carbon audits strategically can enjoy dual benefits. They ensure continued market access and cost reductions.
Importance of Precise Carbon Data
While most companies struggle to reduce their carbon footprint, a key hurdle for many firms is ensuring accurate measurement. Accurate carbon data on products has become vital as customers, regulators, and importers seek increasing transparency from end-to-end supply chains.
Carbon footprint audits provide the product-level emissions data needed to meet reporting obligations, identify emissions hotspots, and comply with carbon border requirements.
CBAM's Definitive Phase and the Immediate Impact on Indian Manufacturing Exports
The CBAM transition period is complete. The final stage mandates EU importers to buy CBAM certificates based on the carbon content embodied in covered products. These include steel, aluminium, cement, fertilisers, electricity, and hydrogen.
India's risk factor is skewed [1]. The fact that Indian producers rely on coal-based steel manufacturing processes, combined with no carbon pricing in India, leads to higher costs for CBAM certificates for every tonne shipped to Europe than the rest of the competitors.
This makes it essential for manufacturers to establish a robust ESG carbon reporting framework supported by accurate product-level emissions data. Carbon content information should be provided at a product level, not an average emissions number from a manufacturing facility; not an estimate, but a verified product-specific emissions number.
Otherwise, EU importers will use default emission values. These default values include mark-ups (up to 30% from 2028 onwards) to account for potential underestimation, meaning they are typically higher than actual emissions for efficient producers. Even if your emissions are lower, without a proper carbon footprint audit to prove it, you pay more.
The UK Carbon Border: What Manufacturers Must Prepare for Before 2027
The UK has followed the EU's approach by introducing its own carbon border adjustment mechanism. The Finance Act 2026, which received Royal Assent on 18 March 2026, provides the legislative basis for UK CBAM. The mechanism will commence on 1 January 2027, covering imports in the aluminium, cement, fertiliser, hydrogen, and iron and steel sectors. The first accounting period will cover the full 2027 calendar year, with a filing and payment deadline of 31 May 2028.
The UK system covers similar products to the EU CBAM, including steel, aluminium, cement, fertilisers, and hydrogen, though glass and ceramics have been excluded from the initial scope. The UK CBAM's emissions methodology is broadly designed to support interoperability with the EU CBAM, helping to reduce administrative burdens for manufacturers. Those who have already begun preparing for EU CBAM compliance can leverage much of this work for UK compliance. Manufacturers that have not yet started preparing will face tighter implementation timelines and greater compliance challenges.
From a practical standpoint, it means you should make an effort to develop your carbon footprint audit system once to meet the highest requirements for both mechanisms.
From Voluntary to Mandatory: How Carbon Audits Are Becoming Trade Prerequisites
The international carbon footprint management market is estimated at USD 11.6 billion in 2025, with a 7.0% compound annual growth rate projected to 2034 [2]. This growth is being driven by regulatory requirements that have made reliable carbon data an essential part of international trade and market access.
CBAM may be the most visible example, but it certainly is not the only one. The carbon reporting mandates of the CSRD, BRSR, and other industry-specific regulations are all pointing toward the same need for verification. Granular carbon data in the context of ESG carbon reporting.
For manufacturers, the age of the voluntary carbon audit may be coming to an end. For exporters in a regulated market, the buyer will require certified emissions data as a prerequisite for trade. A carbon footprint audit will become a necessary part of trade documentation, just like quality certificates.
What Manufacturers Should Prioritise Now
Manufacturers preparing for CBAM and future carbon border mechanisms should prioritise the following actions:
Carry out carbon footprint audits for each export line falling under the CBAM.
Find out the hot spots through emissions by process.
Construct ESG carbon reporting frameworks that deliver credible carbon emissions data.
Ensure independent verification before deadlines for purchasing CBAM certificates.
Develop frameworks to address both the EU CBAM and the imminent UK system.
Manufacturers who act now lock in accurate emissions data and avoid default value penalties. Those who wait risk paying more for the same exports while competitors with verified data trade at lower cost.
Conclusion
Carbon footprint auditing is now moving away from being just an option towards being a necessary condition for market access. This requirement is even more relevant for Indian manufacturers who are exporting steel, aluminium, and cement products to Europe, given the fact that India is highly exposed to the risk of CBAM liabilities [1]. It has to do with the fact that the UK is based on similar considerations.
Manufacturers that establish a robust ESG carbon reporting system today will be better prepared to reduce compliance costs, avoid the use of default emissions values, and maintain uninterrupted access to European markets.
