While acknowledging logistical uncertainties in Belém, the Coalition encourages global businesses to join regional peers in Brazil to showcase scalable solutions in energy, industry, nature protection, and infrastructure.

Mighty Earth calls for a full veto of Brazil's "Devastation Bill," arguing that the legislation would weaken environmental licensing and safeguards for the Amazon, Cerrado, and Pantanal biomes. The statement highlights that the bill contradicts Brazil's international pledges to achieve zero deforestation by 2030 and would undermine the country's credibility ahead of hosting COP30 in Belém.

International climate finance for Brazil grew by 84% between the 2019–2020 and 2021–2022 biennia, reaching an average of US$ 5.1 billion per year. This growth was primarily driven by the energy sector, specifically solar and wind power, and was characterized by a shift toward commercial financing instruments. While Western Europe, led by France, was the largest regional provider, the AFOLU sector—responsible for most of Brazil's GHG emissions—received only 11% of the total finance. Public institutions provided 58% of the funds, with multilateral development finance institutions (DFIs) playing a dominant role, while private finance grew fourfold to reach 42% of the total.

The policy brief examines the impact of the Trump administration's 'reciprocal tariffs' on Africa, noting that they destabilise global trade and signal the end of preferential market access under AGOA. It proposes a strategic response for African nations based on three pillars: rerouting trade via the AfCFTA and BRICS partners, subverting dependency through import substitution and critical mineral value-addition, and negotiating collectively through the African Union.

International climate finance for Brazil averaged US$ 5.1 billion per year in 2021–2022, an 84% increase from the 2019–2020 period. This growth was primarily driven by the energy sector, particularly solar and wind power, and a significant rise in private capital from commercial financial institutions. While Western Europe was the largest regional provider, the report highlights a stark imbalance in sectoral allocation: the AFOLU sector, responsible for most of Brazil's GHG emissions, received only 11% of total finance. The majority of funds were earmarked for mitigation (80%) and delivered via commercial debt and equity, while grants and concessional finance declined by 43%.

International climate finance to Brazil averaged R$ 26.6 billion per year in 2021–2022, an 84% increase from 2019–2020. Growth was primarily driven by the energy sector, specifically solar and wind power, and a significant rise in private commercial financing. While Western Europe, led by France, was the primary source, the AFOLU sector—responsible for most of Brazil's emissions—received only 11% of total funding, mostly through public multilateral sources.

The G20 is a consensus-seeking dialogue mechanism established in 1999 to address global financial crises, comprising 19 countries, the European Union, and the African Union. It operates through a rotating presidency—with South Africa hosting in 2025—and is organized into Finance and Sherpa tracks. While it lacks a formal international mandate or binding decision-making power, it provides a platform for global economic coordination and civil society engagement via 'Engagement Groups' such as the C20.

The fact sheet examines how loopholes in the international tax system allow multinational corporations (MNCs) and the super-rich to avoid taxes, resulting in an estimated US$492 billion in global revenue losses for governments in 2024. It critiques the OECD/G20 Two-Pillar Solution for favoring developed nations and lacking transparency, while advocating for the 'Taxing the Super Rich' initiative and the establishment of a UN Framework Convention on International Tax Cooperation to ensure more democratic and progressive global taxation.

The document asserts that global hunger is caused by a profit-driven system rather than food scarcity, highlighting the role of the 'ABCD firms' and financial speculators in driving up prices. It links food systems to 34% of global greenhouse gas emissions and notes the severe impact of climate-driven droughts in Southern Africa. While acknowledging previous G20 efforts, it criticizes the lack of systemic reforms, such as regulating food speculation or implementing buffer stocks. Under its G20 presidency, South Africa has established a Food Security Task Force to study commodity price volatility and stabilization techniques.

The document analyzes the systemic difficulties G20 nations face in transitioning from fossil fuels, citing economic dependencies, infrastructure lock-in, and social risks to workers. It notes a failure to meet 2009 G20 commitments to phase out subsidies, with G7 and developing nations spending hundreds of billions in 2023. The text emphasizes South Africa's 2025 G20 presidency as an opportunity to champion a people-centered approach involving green industrial hubs and socio-economic safeguards for coal-dependent regions.

This fact sheet defines green industrial policy (GIP) as government strategies to promote sustainable industries and phase out greenhouse gas emitters. It highlights the success of China's electric vehicle industry as a model for GIP but warns that developing countries face significant financing, skills, and technological barriers. The document emphasizes the role of the G20 in shaping global GIP principles, particularly under South Africa's agenda, which focuses on leveraging critical minerals to drive inclusive economic growth and manufacturing in Africa.

The document advocates for Universal Social Protection Floors (SPF) as a means to ensure basic healthcare and income security globally. It highlights South Africa's role during its G20 Presidency to promote a voluntary framework for SPFs and the integration of social protection with industrial strategies. The text emphasizes the need for political will and funding, noting that only 12% of global development targets are currently on track.

The guide emphasizes a 'learn-by-doing' approach, encouraging countries to start with simple methods and increase complexity as capacities grow, while ensuring the integration of gender equality and social inclusion (GESI).

The document analyzes the institutional strain on BRICS caused by its expansion, noting that while the bloc's global influence has grown, its consensus-based governance struggles with divergent member interests. It evaluates Brazil's 2025 presidency, which attempted to prioritize institutional development but saw most structural reforms deferred in the Rio Declaration. The authors contrast the informal nature of the broader bloc with the formal success of the New Development Bank (NDB) and propose six targeted, low-bureaucracy improvements—including a shared document repository and standardized onboarding—to improve operational effectiveness without sacrificing the group's flexible identity.

The report examines how G20 nations, which generate approximately two-thirds of global plastic waste, can utilize extended producer responsibility (EPR) to combat marine plastic pollution. Through a scoping review of 100 sources, it identifies a disparity in effectiveness between mandatory and voluntary EPR schemes, noting that mandatory systems generally achieve higher recycling collection rates. The document provides a detailed mapping of EPR regulations across G20 members and proposes a multi-level approach combining legislative strengthening, market incentives for recycled plastics, technological innovation in ecodesign, and the formal integration of informal waste workers to prevent plastic leakage into the oceans.
