The voluntary carbon market (VCM) is in contraction-then-stabilisation, not growth — the "trillion-dollar VCM" narrative peaked in 2022 and has since corrected. 2024 transaction value settled at ~USD 535M, volumes dropped 25% year-on-year, but 2025 showed something more interesting: USD 12.3 billion in corporate offtake contracts signed at an average of ~$180/t — driven almost entirely by durable-removal + CCP-labelled supply. The market hasn't disappeared; it has re-graded.
Dominant registry by retirements and issuance. ~70–80% of cumulative issued volume historically. Central to any voluntary market conversation.
Second-largest share. Co-benefit-heavy positioning (SDG-tagged credits). Strong Swiss development-finance backing.

Compliance markets are where regulators mandate emissions caps and allocate tradable allowances or credits. They dwarf the voluntary market in value (EU ETS alone cleared hundreds of billions of euros of allowance turnover in 2024). India's CCTS joined this club in 2025/26 and is the single newest major compliance regime — our focus given the customer footprint.
Power + industry + aviation. Covers ~45% of EU emissions. CBAM extension live 2026.
Power + industry + aviation. Linking to EU ETS in discussion; cap-tightening path consulted 2025.
9 sectors · ~740 entities · ~700 Mt CO₂e (~16% of India). Baseline FY23-24. Trading on IEX / HPX / PXIL. First session mid-2026.
Linked with Québec. Extended 2030 + 2045 targets. Covers power + industrial + transport fuels.
Regional Greenhouse Gas Initiative — power-only cap in 12 NE + Mid-Atlantic states. Oldest US carbon market.
Launched 2021 — power-only. Aluminium + steel + cement added 2024/25. World's largest by covered emissions (~40% of China CO₂).
CCTS is India's phased-live compliance carbon market — legally-binding targets have been notified for 7 of 9 sectors, but the first trading session has not yet occurred (expected mid-2026). It is the single newest major compliance regime globally and the single largest shift in India's climate-finance landscape. For Indian project developers, it sits parallel to the voluntary market — not as a substitute.
India's Perform Achieve Trade (PAT) scheme issued Energy Savings Certificates. Cycle I saw just 1.5M of 3.8M ESCerts traded — a low throughput that shapes industry scepticism toward CCTS.
Surplus ESCerts likely convertible to CCCs at a to-be-gazetted ratio. Transition is gradual — BEE has signalled intent but not published the conversion formula.
BEE launched a parallel voluntary offset mechanism in March 2025 (v1, 8 methodologies). This sits alongside CCTS for non-obligated entities who want to generate domestic carbon credits.
Two overlays now sit on top of every carbon credit: Article 6 of the Paris Agreement (country-to-country accounting rules) and the integrity labels that corporate buyers demand (ICVCM CCP, VCMI Claims Code, SBTi alignment). Both shifted materially in 2024–2025 and both directly re-shape what a credit is worth to a serious buyer.
~30+ methodologies approved. Cookstoves + jurisdictional REDD+ approved 2025.
ACM0002 paradox: the renewable-energy methodology was rejected Aug 2024 yet ACM0002 credits remain the most-retired credit type six months later. Supply glut + legacy inventory trumps label adoption short-term.
Verra actions: scrapping AMS-II.G, replacing VMR0006/VMR0011 with new M0174, storage methodology in VVB assessment.
The August 2025 update enforces CCP-or-6.4 credits for any VCMI claim from January 1, 2026.
Practical effect: Silver / Gold / Platinum VCMI tiers all need CCP-labelled or Article 6.4 supply. Non-CCP credits don't disappear from the market — but corporates in the VCMI framework cannot count them.
Impact: re-grades the entire voluntary supply stack overnight.
Post July 2024 Board statement, SBTi permits offsets under specific Scope 3 conditions — previously near-total prohibition in near-term targets.
Still cautious: removals preferred over avoidance; durability + vintage scrutiny tight. Tech premium implication: SBTi-aligned buyers push price signal toward durable removals (biochar, DAC, mineralisation).

2025 was the year renewables overtook coal in global generation — Ember's April 2026 Global Electricity Review logged 33.8% renewable share vs 33.0% coal, the first time in 100 years coal was displaced. Total installed renewable capacity reached 5,149 GW (IRENA, April 2026), up from 3,870 GW end-2024. Net adds hit a record 692 GW — solar PV alone accounted for ~505 GW of that. Energy-transition capital came in at USD 2.3 trillion (BNEF), up 8% year-on-year, with climate-tech VC/equity surging 53% to USD 77.3 bn. Renewables + wind + hydro avoided ~2.6 Gt CO₂e in 2025 versus a fossil counterfactual.
Solar PV is now the dominant growth engine: ~505 GW added in 2025 alone, pushing cumulative capacity past 2,370 GW. Onshore wind adds held at ~140 GW/year. Offshore wind underperformed its 2024 target (8 GW added vs forecast ~12 GW) on rate pressure + permitting slowdowns, but the 2025 pipeline under construction rebuilds momentum (33 GW in build globally — China 9.1 GW, UK 7.6 GW, US 5.9 GW). Battery + thermal storage are the compounding frontier: battery doubled again year-on-year.
| Technology | 2020 | 2022 | 2024 | 2025 | Note |
|---|---|---|---|---|---|
| Solar PV | 714 | 1,055 | 1,865 | ~2,370 | China past 1,000 GW first time |
| Onshore Wind | 697 | 838 | 1,027 | ~1,170 | Stable pipeline; normalised supply |
| Offshore Wind | 34 | 64 | 80 | 89 | 33 GW under construction |
| Hydro | 1,211 | 1,256 | 1,283 | 1,301 | Mostly pumped-storage modernisation |
| Bioenergy | 128 | 149 | 156 | ~160 | Slow; supply-chain bottlenecks |
| Battery storage (GWh) | 17 | 58 | 260 | ~500 | 92 GW / 247 GWh added in 2025 |
| Thermal storage (GWh-th) | ~234 | ~260 | ~330 | ~380 | Preliminary; Rondo + Antora scaling |

Total energy-transition investment hit $2.3 trillion in 2025 — up 8% year-on-year. The mix has shifted materially: electrified transport ($893 bn) is now the single largest category, pushing past renewable generation ($690 bn) as the transition moves from building new supply to electrifying end-use. Grid investment ($483 bn) is finally catching up with generation — a long-flagged bottleneck. Climate-tech VC/equity surged to $77.3 bn (+53% YoY) and transition debt issuance hit $1.2 tn (+17%).
China is now ~42% of global renewable capacity (2,159 GW), underpinned by NDRC Document 136 (market-pricing shift) and the first country ever past 1,000 GW of solar mid-2025. EU at ~18% (934 GW) tracks 66% RE-electricity share — short of the 69% REPowerEU target but moving. US at ~9% faces headwinds from Trump EO 14154 (Jan 2025 IRA freeze, 781 EPA grants cancelled) though legal-impoundment-doctrine challenges limit full rollback. India ~5% (254 GW total RE, 133 GW solar) — hit its 50% non-fossil capacity target five years early; PM Surya Ghar rooftop scheme delivered 7 GW across 2.4M households by end-2025.
| Region | Share | Capacity | Key driver |
|---|---|---|---|
| China | ~42% | 2,159 GW | NDRC Doc 136 market-pricing shift · first past 1 TW solar |
| European Union | ~18% | 934 GW | REPowerEU · Clean Industrial Deal €100bn · EU ETS signal |
| United States | ~9% | ~460 GW | IRA operative but under freeze (EO 14154, Jan 2025) |
| India | ~5% | 254 GW (133 solar) | 500 GW non-fossil by 2030 · PM Surya Ghar · CCTS mid-2026 |
| Rest of Asia | ~12% | ~620 GW | Japan GX · Korea K-ETS · Vietnam PDP8 grid |
| Rest of world | ~14% | ~720 GW | Brazil hydro + COP30 solar push · MENA auctions · Africa <3% |
Once renewable penetration crosses ~55%, storage + grid flexibility become the binding constraint — which is why dispatchable heat (TES) and grid batteries are re-pricing on dispatchability, not just tCO₂e. Battery storage installed 92 GW / 247 GWh in-year in 2025, taking cumulative past ~500 GWh. BNEF expects ~15× growth to ~2 TW / 7.3 TWh by mid-2030s. Thermal energy storage is earlier but scaling: Rondo (brick, 1,000–1,500°C, 16–18hr discharge) now operates commercial units at Calgren CA and is expanding into Indian cement + steel; Antora (graphite, up to 2,000°C, 25hr) commissioning Fresno CA facility 2025.
Main-case trajectory: 9,530 GW cumulative by 2030 (2.6× 2022), generation share ~46%. Accelerated case: 10,400+ GW (~90% of the COP28 tripling pledge, ~50% generation share). COP28 tripling target of 11,500 GW remains off-track in main case. Post-2024 policy shifts: Trump IRA freeze modelled as slower — not reversed — US buildout; India National Electricity Plan 2023 (NEP13) draft pushes coal phase-down; EU REPowerEU three-years-on review (2025) maintained 592 GW solar + 510 GW wind by 2030 targets.
Industrial process heat consumes over 70% of industrial energy. AI-optimised CSP can abate ~10% of global CO₂ from IPH.

Generative AI has moved from demo to production at a pace that shocked most analysts. ~94% of Fortune 500 companies are now using or actively exploring GenAI (per Deloitte's 2026 waves of the State of AI survey), VC investment surged past $80 B in 2025, and agentic systems are emerging as the next inflection — moving beyond chat-style interactions into autonomous task execution with governance frameworks to match.
Top models now score above ~90% on MMLU, which was the gold-standard 2023–2024 benchmark. Attention has shifted to harder tests: MMLU-Pro, GPQA Diamond (graduate-level reasoning), Humanity's Last Exam, Arena Hard, and agentic / coding benchmarks like SWE-Bench Verified and LiveBench.

Shift vs 2024 (Deloitte, Q4 2025 wave): mature-integration tier doubled from ~8% → ~17%. The "no plans" cohort shrank from ~12% → ~6%. Pilot-to-production friction remains the biggest enterprise complaint — ROI payback medians still sit at ~18 months for horizontal deployments.
Closed-source models (OpenAI, Anthropic, Google) still dominate enterprise production workloads, but the release of DeepSeek R1 (Jan 2025) at a fraction of comparable training cost, followed by Llama 4 (April 2025) and Mistral Large 3, materially changed the economics. Open weights are now viable for many workloads where cost + data sovereignty are constraints.

TenzaOne's AI assessment stack — 7-agent VCS assessment, AI concierge, Net0Link BIRAI digital twin (1,500+ datapoints/minute, ~90% autonomous HVAC operation) — sits at the intersection of agentic AI + industrial-M&V. Our dMRV chain (sensor → BMS → AI → MCP → DePIN → blockchain) is architected so AI agents produce signed evidence that registries (Verra / ACV Agencies for India CCTS) can cite without re-verifying from raw telemetry. The agentic-AI wave maps directly to how we generate EE and RE credits end-to-end.
