Green ammonia is a CBAM arbitrage. And it’s timed perfectly.
India’s fertiliser sector runs on natural gas — 86% sourced from West Asia. The Hormuz crisis has made supply vulnerability impossible to ignore. The decarbonisation path runs through green hydrogen and the HPO. For green ammonia exports to the EU, CBAM liability is zero — a direct financial premium that arrives exactly when the National Green Hydrogen Mission needs it most.
India’s fertiliser industry is built on natural gas. The gas goes in, ammonia comes out, and then urea. Decarbonising the sector means replacing that gas with green hydrogen — which is technically straightforward but economically still a significant stretch at normal prices. The EU CBAM has been forcing the timeline since January 2026. The West Asia war has collapsed it further.
The fertiliser sector’s decarbonisation problem is a feedstock problem. Ammonia synthesis — the first step in making urea and other nitrogenous fertilisers — requires hydrogen. Today that hydrogen comes from natural gas through steam methane reforming, generating substantial CO₂ as a by-product. Replacing grey hydrogen with green hydrogen produced from renewable electricity-powered electrolysis is the only credible route to decarbonising the sector at scale. The National Green Hydrogen Mission and its SIGHT programme are the primary policy instruments targeting this transition.
There is also an energy security dimension that the West Asia war has made impossible to ignore. India spent over Rs 1.68 lakh crore on fertiliser subsidies in FY2025-26 — a figure that exceeded the Revised Estimate even before the war’s full impact was captured. The April 2026 government urea tender settled at $959 per tonne on the east coast, nearly double the pre-war price of $510 per tonne. Green hydrogen produced domestically from renewable electricity eliminates both the import dependency and the subsidy volatility. At $959/t urea import prices, the implied government subsidy per tonne exceeds Rs 75,000 — more than the total production cost of green urea at current green hydrogen prices. The crossover has arrived.

The fertiliser sector faces a distinct combination of trade, hydrogen, carbon, and energy policy pressures that no other covered sector matches — now amplified by the West Asia supply shock.
EU Carbon Border Adjustment Mechanism
Nitrogenous fertilisers — urea, ammonia, nitric acid and ammonium nitrate — are among the six product categories covered by CBAM. From January 2026, EU importers must purchase certificates for the embedded emissions in each tonne. India’s urea and ammonia exports carry some of the highest embedded emission intensities of any CBAM-covered product. Producers targeting the EU market face an immediate financial incentive to begin the green ammonia transition. Green ammonia carries zero CBAM embedded emissions — a direct financial premium that grows as EU ETS prices rise.

The fertiliser sector is the primary target for the Hydrogen Purchase Obligation — the mechanism that will mandate minimum green hydrogen procurement by fertiliser producers. The SIGHT programme provides production incentives of Rs 8.82/kg for the first year declining over three years. SECI’s second major green hydrogen tender awarded 450,000 tpa of capacity in March 2025 with 10-year offtake agreements. The HPO framework was read in the April 2026 articles on this site: The HPO Framework →
Green Hydrogen repository →CCTS GEI Targets — 20 Plants, October 2025 Notification
MoEFCC notified final GEI targets for the fertiliser sector on 8 October 2025 covering 20 major ammonia-urea plants. The compliance year FY2025-26 is live. ACVA Form A submission deadline is approximately June-July 2026. Plants operating above their GEI target must buy CCCs at Rs 1,740/tCO₂e or face a penalty at twice that rate. Modern integrated plants like Chambal Gadepan are positioned as natural CCC sellers; older plants like RCF Trombay and NFL Nangal face buyer pressure. The Carbon Credit Trading Scheme administered by BEE is the compliance mechanism.
Carbon Markets repository →Air Act and Hazardous Waste Rules
Ammonia plants are subject to stack emission standards for particulate matter, nitrogen oxides, and ammonia fugitive emissions under the Air Act, requiring ongoing investment in pollution control equipment. The handling, storage, and disposal of hazardous industrial waste — including spent catalysts from reforming units — is governed by the Hazardous Waste Management Rules administered by MoEFCC. New plant capacity requires EIA clearance. N₂O from nitric acid plants (GWP of 273) is one of the highest-leverage abatement opportunities in the entire sector — catalytic abatement pays back in under two years at current CCC prices.
Environmental Regulations repository →Unlike steel or aluminium, the pathway is clear — the question is sequencing and economics
The fertiliser sector has a relatively clear single decarbonisation pathway: replace grey ammonia with green ammonia. The technology is known. The policy framework exists. The question is sequencing — which steps can be taken now versus which must wait for green hydrogen to fall further in cost — and economics, which the West Asia war has dramatically shifted in favour of faster transition.

The fertiliser sector’s decarbonisation is closely tied to the power sector through renewable electricity needs, to freight through WDFC distribution of imported urea, and to steel through shared carbon market obligations.
