Editorial & data methodology

Taxonomy

The site is organized as 8 industry channels, subdivided into 86 major categories and roughly 500 specialized sub-domains covering the full new-energy and carbon-neutrality industry chain. The taxonomy is refined with AI-assisted analysis and reviewed editorially, so that every segment a professional searches for has one clear home.

Content types

Each sub-domain is served by three standardized content types:

• Brand rankings — league tables locked to verifiable, published data.
• Procurement evaluations — selection criteria and buying guidance.
• Technical guides — concepts, terminology, costs, policy, and practice.

Data and sources

Rankings and evaluations use public data from research institutions (for example SNE Research, InfoLink, ICC), company disclosures, and government statistics. Every figure is annotated with its origin. Institutions differ in scope and methodology; where scopes differ we say so, and figures from different sources are never mixed to compute market share.

Content is expanded in phases per segment and content type. Where a page has not yet been compiled for a sub-domain, the category page says so rather than showing estimated data.

Independence

Rankings and data are for reference only and do not constitute investment or procurement advice.

Corrections and disputes are handled through the disputes & corrections process.
