May 2026 Climate Brief: India CCTS, EU CBAM, and the Road to COP30

Welcome to Csquare’s monthly climate and carbon market brief. May 2026 was a quiet headline month but a heavy operational one — most of the action is happening inside compliance teams, not on the front pages. Here is what changed and what Indian sustainability leaders should be doing about it.

1. India CCTS: from policy to compliance

The Carbon Credit Trading Scheme has crossed an important threshold this quarter. The Bureau of Energy Efficiency has now notified emission intensity targets for nine sectors — aluminium, cement, chlor-alkali, pulp and paper, petroleum refining, petrochemicals, textiles, plus the two added in early 2026 — covering roughly 490 obligated entities. Targets use FY2024 as the baseline and apply to FY2026 and FY2027 compliance years.

Key milestones for the next two quarters:

• Q2 2026: Grid-India registry opens for entity registration. Obligated entities should have their registration documentation ready now, not later.

• Q3 2026: First compliance monitoring period begins with MRV (Monitoring, Reporting, Verification) data collection.

• Q4 2026: First Carbon Credit Certificates expected to be issued to over-performing entities.

• Mid-2026: First CCC trading is expected to launch on power exchanges.

Action this month: if you are an obligated entity, lock in your verifier, finalise your MRV data systems, and run a dry-run intensity calculation against your FY2024 baseline before the registry opens. The companies that are going to do well in the first compliance year are the ones that already know whether they will be net buyers or net sellers.

2. EU CBAM: the definitive regime is biting

CBAM entered its definitive regime on 1 January 2026, and the Q1 2026 CBAM certificate price has been published at €75.36 per tonne of CO₂e — calculated as the weighted average of EU ETS auction clearing prices from January through March 2026.

For Indian exporters of steel, aluminium, cement, fertiliser, and certain chemicals, the financial impact is now real, not theoretical. Civil Society for Environment (CSE) analysis suggests CBAM could impose a price burden of up to 25% on affected steel and aluminium exports to the EU.

The early evidence is also showing competitive differentiation: Indian firms with emission intensities at or below EU averages are sustaining trade volumes and even raising prices 2–3%, while high-intensity producers are seeing realised prices fall around 9%.

Action this month: if you export CBAM-covered goods to the EU, your verified emissions data is now your competitive moat. Get a CBAM-aligned product carbon footprint audited for your top three export SKUs, and use the data in your customer conversations — not just in your customs filings.

3. Voluntary carbon market: prices firming on integrity

The voluntary market continues its bifurcation. High-integrity removals — ICVCM Core Carbon Principle (CCP)-labelled, post-2024 vintage, with verified co-benefits — are trading at clear premiums. Older avoidance credits and unlabelled supply remain under pressure. Buyer demand is increasingly concentrated in the top quartile of supply.

Action this month: if your 2026 offset portfolio is still weighted toward pre-2020 vintage avoidance credits, that exposure is now a reputational risk on top of an accounting risk. Refresh your procurement policy to require post-2023 vintages and CCP-aligned methodologies as a baseline.

4. COP30: Belem prep starts now

COP30 in Belem, Brazil, in November 2026 is shaping up as the implementation COP for Article 6.4 — the centrally-supervised mechanism for international carbon credit trading under the Paris Agreement. The early signals from the supervisory body suggest the first authorised activities and corresponding adjustments will be operationally live in 2027, which makes the next six months the window for corporates to position themselves as early movers.

Action this month: if your company has international operations or international offset ambitions, brief your leadership team on Article 6.4 mechanics now — specifically, what corresponding adjustments mean for double-counting risk and which bilateral host-country agreements India is signing.

5. BRSR Core: assurance season is here

For the top-1,000 listed Indian companies, BRSR Core assurance is now operationally live for FY 2025–26 disclosures. Assurance providers are reporting the same patterns we have seen on the ground: Scope 3 disclosure quality is highly variable, supply chain data is the weakest link, and water and waste reconciliation is taking longer than companies expected.

Action this month: if you have not yet handed your data pack to your assurance provider, do it this week. The portal slowdown in the final week of the cycle is a reliable feature, not a bug.

What to watch in June

• CCTS Phase 1 entity registration opens — watch the Grid-India registry portal.

• Q2 2026 CBAM certificate price publication, expected mid-July.

• Article 6.4 supervisory body meeting outcomes ahead of COP30.

• SEBI guidance refresh on BRSR Core for the FY 2026–27 cycle.

• Indian voluntary market price discovery as CCTS launch dates firm up.

The companies that are quietly doing the operational work right now — baselining, verifying, registering — are the ones that will be acting from a position of strength when the next set of disclosure deadlines hit.
