This article introduces systems thinking and explains how it is reshaping sustainable and impact finance by addressing interconnected systemic risks like climate change and inequality. It outlines four emerging applications; from systemic risk management to systems-informed stewardship, highlighting the implications for investors’ roles, tools, and decision-making.

The report argues that behavioural public policy has over-emphasised individual-level (“i-frame”) solutions, often aligning with corporate interests and weakening systemic reform. It contends that structural (“s-frame”) interventions, alongside institutional changes in research and policy design, are necessary to address entrenched social and economic problems effectively.

UNEP’s State of Finance for Nature 2026 finds global finance remains heavily skewed towards nature-negative activities. In 2023, US$7.3 trillion harmed nature versus US$220 billion for nature-based solutions. Meeting Rio Convention targets requires more than doubling nature investment by 2030.

Climate Arc is a non-profit organisation focused on accelerating capital flows to climate solutions. It develops data tools, research, and insights to assess transition performance across companies, sectors, and markets. Climate Arc supports investors, policymakers, and practitioners seeking credible, decision-useful climate intelligence, with a global perspective and independent analytical approach.

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.

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 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.

This report analyses climate-driven food price inflation in the UK, linking global heat and drought shocks to rising import costs. It projects 25–34% cumulative food inflation by 2050, with disproportionate impacts on low-income households and increased poverty risks.

The report argues that green industrial policy must actively manage a fossil fuel wind-down. It contends that renewables expansion alone is insufficient, calling for public planning, regulation, and ownership to ensure equitable decarbonisation and prevent fossil fuel liabilities shifting to the public.

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.

The report examines the mainstreaming of impact investing, highlighting market growth, increasing institutional participation, evolving standards, and measurement challenges. It outlines barriers to scale and proposes actions to improve integration, transparency, and credibility across investment markets.

The report assesses risks to Australia’s fossil fuel exports and outlines how aligned trade, aid and climate finance policies can build demand for green exports. It proposes sustainable growth partnerships in the Indo-Pacific to secure markets, attract investment and support regional decarbonisation.

The report evidences how income inequality drives environmental, social and health harms, worsening trust, mobility, wellbeing and climate impacts. It shows cross-country correlations and calls for structural reforms, including redistribution, public investment and participatory governance, to reduce disparities and improve population outcomes.

The report outlines a universal basic services approach to UK transport, highlighting inequitable access, high emissions, and car dependence. It assesses current government reforms and recommends long-term, publicly oriented investment to expand affordable, integrated, low-carbon mobility, prioritising public transport and active travel within environmental limits.
