About 4ClimateChange
A focused search platform for climate change, global warming, climate science, policy, mitigation and adaptation -- built to help people find reliable, relevant, and usable information on the public web.
What 4ClimateChange is
4ClimateChange is a subject-specific search engine designed to make climate-related information more discoverable, usable, and trustworthy for a broad audience. We index publicly available content on the open web -- including scientific papers, policy reports, verified datasets, NGO publications, news, and vetted product and service listings -- and we present that content in ways that prioritize relevance for climate science, climate policy, mitigation and adaptation, and climate-friendly choices.
Rather than replacing general-purpose search, 4ClimateChange is a complementary tool. It aims to reduce the friction that comes with searching for technical climate topics across disparate websites and formats. The platform helps users move from discovery to understanding and then to action by surfacing focused results, contextual summaries, and practical filters tuned to climate queries.
Why we built it
Climate decision-making increasingly rests on a mix of science, policy, economics, and practical implementation. That mix can be difficult to navigate because authoritative material lives in many places and formats -- peer reviewed journals, IPCC reports, national policy documents, local adaptation plans, NGO analyses, open datasets, and product certifications.
Search on technical and policy topics often returns broad or poorly contextualized results. For example, a query about "sea level rise projections for coastal adaptation" could bring up academic models, press coverage, commercial services, and outdated material without clear indicators of relevance or confidence. 4ClimateChange was developed by search engineers, domain experts, and experienced climate practitioners to bridge that gap. Our aim is to help researchers, practitioners, journalists, public officials, students, and interested members of the public find the information they need with less sorting and more context.
We focus on helping people ask useful questions -- and find answers that lead to well-informed actions such as mitigation planning, adaptation design, procurement of low carbon materials, or public communication of climate impacts.
How it works -- an overview
The platform combines multiple technical and editorial approaches to index and present climate information on the public web. Our process includes collection, organization, relevance ranking, and user-facing summarization.
Collection and indexing
We maintain specialized indexes that gather public content from selected sources:
- Peer reviewed journals and preprint servers for scientific papers.
- Intergovernmental assessments and national government releases, including IPCC reports and related technical briefs.
- Public datasets and climate repositories, including open data portals and emissions data sources.
- NGO and think tank reports, policy briefs, and technical guidance documents.
- Reputable news outlets and climate journalism focused on breaking climate and policy updates.
- Commercial listings and product pages with documented certifications and lifecycle information for shopping searches.
Relevance and ranking
We use relevance models tuned for climate topics. Those models combine:
- Topic detection that recognizes climate science, policy analysis, or adaptation guidance.
- Source credibility signals that prefer transparent methodology, peer review, or verifiable certifications.
- User intent classification that differentiates queries for research, policy, procurement, education or general information.
- Recency and provenance filters, especially for news and policy updates where timing matters.
Summarization and contextual assistance
Long reports and technical papers can be hard to scan. We integrate AI-generated summaries and extract key data points, while clearly indicating confidence levels and linking back to primary sources. The AI chat assistant helps users interpret findings, draft materials, translate technical language into plain language, or generate structured outputs like policy drafts, adaptation plans, or data explanations.
Example workflow: A city planner searches for "heatwave early warning system climate models" -- the platform returns peer reviewed model studies, national heatwave guidance, examples of municipal early warning systems, applicable datasets, and a concise summary with suggested adaptation steps and citation links.
What you can search and find
4ClimateChange indexes a wide array of content types so users can find both high-level overviews and the technical materials needed for detailed work. Typical searchable content includes:
- Scientific papers, peer reviewed articles, and preprints on climate science, climate models, mitigation strategies and climate impacts.
- IPCC reports and related technical summaries, scenario analyses and model explanation documents.
- Government policy documents, national emissions inventories, adaptation plans, and environmental policy analyses.
- NGO reports, research portals, climate bibliographies, and climate archives that are relevant to advocacy, project design, and policy reform.
- Open climate datasets, emissions data, and climate repositories that support analysis and reproducible research.
- Technical reports, consultancy briefs, and vetted climate service providers for implementation and procurement decisions.
- Climate news, breaking climate coverage, policy updates, IPCC news, and investigative journalism.
- Shopping and procurement listings for sustainable products, green building materials, solar panels, heat pumps, energy efficient appliances, EVs and clean energy equipment, with lifecycle assessments and green certifications where available.
- Tools and services such as carbon calculators, carbon accounting software, carbon markets resources, carbon removal options, and climate finance reports.
Searches can be broad (e.g., "renewable energy policy updates") or specific (e.g., "emissions data for cement production in India 2015-2020"). Results are grouped by source type and include filters that make it easier to locate the most relevant materials.
Features you'll find useful
We designed tools and interface features specifically for climate-focused queries. These help narrow search results and provide practical context.
Custom filters built for climate queries
Filter results by:
- Source type: scientific papers, policy documents, datasets, NGO reports, news, shopping listings.
- Emissions type: scope 1/2/3, sector-specific sources (energy, transport, industry, agriculture).
- Geographic scope: global, national, subnational, city-level.
- Time horizon: historical data, near-term projections, long-term scenarios.
- Methodological approach: empirical studies, model projections, lifecycle assessment, scenario analysis.
AI chat assistant and climate summaries
Our chat assistant can:
- Summarize long technical reports and highlight key findings and uncertainties.
- Explain model outputs, climate datasets, and technical terminology in plain language.
- Help draft policy briefs, grant proposals, adaptation plans, or community outreach materials.
- Provide citation-aware summaries and suggest primary sources for verification.
Summaries and generated content always include links to underlying sources and statements about confidence levels. We encourage users to consult original documents for technical decisions.
Shopping and procurement support
For procurement and consumer-facing decisions, the shopping search emphasizes documented attributes that matter for low-carbon choices:
- Green certifications and independent verification.
- Product specifications and energy performance (e.g., efficiency ratings for heat pumps or appliances).
- Lifecycle assessments and reported embodied carbon when available.
- Comparisons across similar products and supplier transparency.
News and policy tracking
Track breaking climate news, global climate summits, net zero announcements, policy reforms, and climate litigation. Our news index privileges source transparency and timeliness while offering quick access to ongoing coverage of extreme weather events such as heatwaves and sea level alerts.
Research-friendly capabilities
- Search by dataset names, climate repositories, or technical keywords (e.g., "CMIP6 climate models" or "IPCC AR6 sea level rise projections").
- Access to research portals, climate bibliographies, and open data links for reproducible work.
- Tools to extract emissions data and export basic citation metadata for academic use.
Standards, source selection and transparency
We prioritize transparency about how sources are selected and how results are ranked. Our approach is intentionally conservative with respect to source claims and methodological clarity.
Key principles:
- Prefer sources that are explicit about methods and data: peer reviewed studies, official government releases, intergovernmental assessments, and NGO reports with documented methodologies.
- Flag uncertainty and limitations in AI-generated summaries and provide links to original datasets and technical appendices.
- Index verified datasets and open data portals rather than private or restricted datasets.
- Identify and tag items such as policy briefs, technical reports, and lifecycle assessments to help users assess applicability and reliability.
We do not sell user data to third parties and aim to keep the processes behind ranking and AI generation understandable. Where AI assists with summaries or drafting, we explain the provenance of the information and the level of confidence in the output.

The broader climate ecosystem we cover
Climate change is an interdisciplinary field. Our indexes aim to reflect that breadth while keeping results practical and oriented toward action. The broader ecosystem includes:
- Climate science and modeling communities working on climate models, emissions scenarios and projections.
- Policy and governance actors producing climate policy, environmental policy, and policy analysis.
- Finance and markets including climate finance, carbon markets, and climate funding mechanisms.
- Technology and industry contributions such as renewable energy, green technology, energy transition, and carbon removal approaches.
- NGOs, think tanks, and academic institutions publishing NGO reports, technical reports, and adaptation guidance.
- Journalism and communication channels producing climate journalism, breaking climate stories, and science communication pieces.
- Local governments and community organizations implementing adaptation plans and resilience measures at the city and regional level.
We surface materials across this ecosystem so users can move from high-level overviews to the technical details needed for implementation. For example, a user researching "carbon removal" can find peer reviewed studies, project demos, carbon markets analyses, and relevant policy discussions.
How we handle AI, summaries and citations
AI tools can reduce reading time by extracting key points from long documents, but they also require clear signaling about limitations. Our AI features are designed with that in mind.
- Summaries include short, clearly labeled synopses and links to source material so users can verify claims and consult primary data.
- Confidence levels and uncertainty notes are provided when summarizing model results, climate projections, or policy implications.
- We favor traceable outputs that point to specific paragraphs, tables, datasets, or figures in the original documents.
- AI is used to assist with drafting (policy drafts, grant writing, FAQs) but outputs are presented as starting points that require review by domain experts before formal use.
These safeguards are in place because climate decisions have consequences and require careful review of primary sources and methodologies.
Community, collaboration and inclusion
4ClimateChange is not an isolated tool. We work with academic institutions, data portals, NGOs, and practitioner networks to expand and refine our indexes. Collaboration helps us identify emerging repositories, important NGO reports, and new data sources.
We welcome feedback, source recommendations, and partnerships that improve coverage and clarity. If you represent an institution with specialized data or resources that should be indexed, please reach out via our contact page.
Privacy, ethics and responsible use
We take user privacy and responsible data practices seriously. Our public-facing search indexes only content that is openly available on the public web. We do not index private or restricted data sources without explicit permission.
Privacy highlights:
- We do not sell user data to third parties.
- Search logs are used internally to improve relevance models and user experience, subject to privacy protections and aggregation where appropriate.
- AI outputs are traced to sources, and users are encouraged to verify details in primary documents before making policy or technical decisions.
Responsible use guidance: Our content is intended to inform and support decision-making. It is not a substitute for professional advice in legal, medical, or financial matters. Users should rely on qualified professionals when such decisions are at stake.
