Éclaircies is an independent expert collective producing open-source climate, energy and environmental analysis. It develops data tools, methodologies and reports to improve transparency on fossil fuel exposure, emissions and transition risks. Outputs support researchers, journalists, civil society and policymakers seeking evidence-based insights across global climate finance and energy systems worldwide.

This report argues that embedding circular economy principles within the Sustainable Development Goals could revive stalled progress. It outlines five global policy priorities and proposes a 2050 blueprint linking circularity, inclusive growth, trade, finance and standards to post-2030 development agendas.

This report analyses barriers to scaling private finance for nature, highlighting a US$700 billion annual biodiversity finance gap. It clarifies nature-positive finance, assesses risk–return challenges, regulatory gaps and data issues, and outlines instruments to redirect capital from harmful activities towards halting and reversing nature loss.

The article defines “climate finance justice” as a framework for analysing how financialised climate action shapes equity, power, and outcomes. It critiques climate finance mechanisms, including UNFCCC processes and voluntary carbon markets, and argues for justice-centred approaches that address historical responsibility, governance, and uneven impacts.

The report argues that limiting warming to 1.5°C is no longer realistic and may hinder preparedness. It calls for acknowledging higher warming scenarios, accelerating mitigation, and adopting disruptive policy, financial, and governance approaches to manage climate and nature risks in a likely 2°C-plus world.

The report analyses US climate-driven mortgage risk, showing floods as the dominant driver of post-disaster foreclosures. Rising insurance costs, coverage gaps and falling property values create hidden credit losses. It argues climate risk should be treated as a sixth core credit assessment factor.

The report outlines the EU’s White Paper on European Defence and the ReArm Europe Plan, targeting defence readiness by 2030 through closing capability gaps, strengthening the defence industrial base, and mobilising over €800 billion via public, EU, and private funding mechanisms.

Bpifrance’s European Defence Bond Framework defines principles for issuing use-of-proceeds bonds financing eligible defence-sector projects, mainly SMEs, to support European sovereignty. It details eligibility criteria, exclusions, ESG safeguards, governance, reporting, and proceeds management, while stating the bonds are not ICMA-aligned sustainable instruments.

The report analyses global financial links to arms production, showing significant funding for weapons despite rising conflict. It contrasts this with values-based banks, particularly GABV members, which largely exclude arms financing, arguing divestment supports peace, reduces risk, and aligns finance with social and environmental objectives.

IFC’s report argues that repurposing power market designs is critical to achieving affordable, reliable and sustainable electricity. Drawing on global data, it finds competitive markets attract private capital, improve access and accelerate renewables, while recommending tailored reforms guided by innovation, integration and institutional strength.

GARP benchmarks 13 vendors’ asset-level climate physical risk models, finding wide dispersion in hazard and damage estimates due to differing data, assumptions and methods. The report stresses due diligence, transparency and improved asset data when selecting vendors.

The report assesses energy financing by 65 major banks (2021–2024), finding fossil fuel finance more than double sustainable power supply. The energy supply financing ratio stagnates around 0.42:1, far below net-zero benchmarks, with regional disparities and weak translation of climate commitments into financing shifts.

The report assesses nature-based solutions for climate resilience in sub-Saharan Africa, reviewing nearly 300 projects. It finds growing adoption but insufficient scale, highlighting financing, policy, and capacity gaps, and recommends integrating NBS into infrastructure planning, diversifying funding, and strengthening social inclusion and local capability.

This report argues that insurability is a strategic indicator of financial viability in a climate-disrupted economy. It explains how insurance, risk modelling, resilience investment, and policy alignment shape access to capital, asset values, and transition finance, urging leaders to embed insurability into decision-making.

ICMA’s June 2025 Guidance Handbook clarifies practical application of Green, Social, Sustainability and Sustainability-Linked Bond Principles, covering use of proceeds, governance, reporting, verification and market issues. It supports consistent labelling, transparency and market integrity across sustainable debt instruments.

The article argues that while climate disclosure and green finance initiatives have expanded since Mark Carney’s “tragedy of the horizon” speech, they have failed to shift capital at the scale required to address climate and nature risks. It contends that deeper structural reforms to financial valuation, incentives and capital allocation are needed to move beyond managing symptoms toward financing real-world solutions.
