FAQs

We curate the best questions from individual reports and keep answers short. Below are baseline FAQs you’ll always see here; the hub will append fresh Q&As as we publish.

What policy levers matter most for near-term deployments?
Incentives that move all-in cost (credit, rebate, CfD), grid interconnection reforms, carbon pricing floors, and procurement mandates.

Where do projects clear first?
Where input prices (power/fuel), capacity factor, and incentives align—plus fast-track interconnection and siting.

How should I read the market size range?
It reflects scenario bounds (conservative vs. accelerated), not uncertainty alone. We show a median for planning.

Why do patent “signals” matter?
They indicate where vendors are investing in analytics, controls, materials, or processes likely to reach market.

How often are figures refreshed?
When policy or component prices change materially, otherwise on a steady cadence (typically quarterly).

Can I reuse tables in board materials?
Yes—see license terms in each report. Single-user license is standard; team licenses available.

Methodology & sources

Methodology

A methodology that relies exclusively on primary data from government, academic, and verified organizational sources. The approach avoids any commercial aggregators or unverified reports to ensure high-quality data.

Key aspects of the methodology include:

Direct Data Extraction: Quantitative data is extracted directly from primary publications and official statistics.
Comparative Analysis: Regional statistics are normalized to allow for accurate comparisons of market sizing, investment trends, and growth rates.
Framework-Based Segmentation: Market segments are mapped using established frameworks from organizations like SASB, GRI, and CDP.
Verified Tracking: Capital flows and investments are tracked via major international financial institutions, including the IMF, World Bank, and OECD, while patent counts are sourced directly from government databases like USPTO, EPO, and WIPO.

Key Data Sources

Aa foundation of high-trust, official sources. The primary sources include:

Government & Regulatory Bodies:
- SEC EDGAR Filings and EU Taxonomy Reporting: Used for corporate financial data and official regulatory compliance information.
- EPA Environmental Data: Provided U.S.-specific climate statistics.
- Patent Databases (USPTO, EPO, WIPO): Sourced for direct counts and analysis of patent filings.
International & Financial Institutions:
- World Bank ESG Portal, IMF, and OECD: Acted as the primary sources for sovereign ESG data, capital flow tracking, and institutional investment analysis.
- Regional Development Banks (EIB, ADB, AfDB): Supplied data on infrastructure investment and grant funding.
Global Reporting & Standards Organizations:
- CDP Climate Database: Provided corporate ESG data and disclosures.
- GRI Sustainability Reports and SASB Standards: Used for certified reporting disclosures and sustainability accounting standards.
- TCFD (Task Force on Climate-related Financial Disclosures): Referenced for its climate financial risk disclosure framework.
Academic & Technology Sources:
- Stanford AI Index, MIT Technology Review, and NASA: Provided data on technology innovation, R&D, and patent activity in the climate and ESG sectors.

Glossary (quick defs)

Key Concepts & Financial Terms

Carbon Intelligence: This refers to the use of software, analytics, and advanced platforms for the scientific measurement, management, and reporting of carbon emissions and other climate metrics. Spending on carbon intelligence is a key market metric, particularly in the US and EU.
Climate Finance: This encompasses capital allocations and investment flows directed towards climate projects and mitigation activities. Global climate finance surpassed $1.7 trillion in 2024 and is projected to reach nearly $2 trillion in 2025.
ESG (Environmental, Social, and Governance): While the sources do not spell out the acronym, they refer to ESG as a framework driving corporate compliance, reporting, and investment decisions. Key activities include ESG disclosures, reporting adoption, and ESG-linked loans. The market is segmented by ESG applications in sectors like energy and finance.
Green Bonds: A financial instrument used to raise capital for climate and environmental projects. Green bond issuance in OECD countries was forecast to exceed $650 billion in 2025, with the European Investment Bank (EIB) being a leading issuer.
Net-Zero: A commitment made by organizations to align with science-based thresholds for emissions reduction. The number of companies with net-zero pledges is a key metric, and firms undergo net-zero compliance audits to verify their strategies and claims.
Scope 1, 2, and 3 Emissions: The sources refer to these as categories of emissions that companies track and report on, with a particular focus on the challenges of reporting Scope 3 emissions. Analytics platforms from companies like IBM, Microsoft, and SAP are designed to track Scope 1-3 emissions. The sources do not define what each scope includes.
