Our editorial policy explains how The Planet Brief researches, writes and reviews sustainability, carbon markets, ESG, net zero and green finance articles.
Last updated: May 2026
Editorial mission
The Planet Brief exists to make sustainability topics easier to understand without stripping away the complexity that matters. We write for founders, operators, investors and business readers who need clear explanations of carbon markets, ESG reporting, net zero, climate claims and green finance.
Source standards
For regulatory, market, reporting and financial topics, we prefer primary or authoritative sources. These include official government guidance, regulators, standards bodies, scheme administrators, recognised market organisations and original policy documents.
Examples include sources such as the GHG Protocol, SBTi, ICAO, the European Commission, UK government guidance, the FCA, ICMA and official carbon market scheme documents. We may also use credible journalism, academic work or practitioner sources when they add useful context.
How we handle uncertainty
Sustainability regulation, carbon markets and green finance change quickly. Where rules, prices or market conditions may change, we aim to make that clear and avoid presenting moving information as permanent fact.
Financial and professional boundaries
Green investing content is for information and education only. It is not financial advice, investment advice, a recommendation, or a personal financial promotion. ESG reporting, carbon accounting and compliance content is general information only and is not legal, accounting, tax or regulatory advice.
Commercial independence
The Planet Brief may reference related projects including The Carbon Workbench where the tools are relevant to the article. We aim to keep these references useful, limited and clearly contextual. Sponsored content, affiliate links or material commercial relationships will be disclosed where relevant.
Review and updates
We review priority articles when rules, guidance or market conditions materially change. Articles may include an updated date where useful for readers.
