Overview:
This article highlights the two major outcomes of the 2025 G20 Summit in South Africa—new climate action commitments and renewed efforts to ease the growing debt burden on developing countries. Despite the U.S. boycott, leaders pushed forward on Paris Agreement goals, adaptation funding, and debt sustainability reforms. The piece explains how these decisions could significantly impact the Global South, while noting that their success will depend on financing, coordination, and political follow-through.

A Historic Summit on African Soil
The two-day G20 Summit in Johannesburg, South Africa, concluded Sunday with historic significance — it marked the first time an African nation served as host. South African President Cyril Ramaphosa closed the gathering by thanking global leaders for upholding multilateral cooperation during a politically turbulent moment.
The summit notably proceeded without the United States, following President Donald Trump’s decision to boycott. Citing allegations of corruption and human rights concerns in South Africa — including controversial claims regarding the treatment of white South Africans — Trump’s absence made global headlines. Still, delegates from Japan, India, France, Brazil, Saudi Arabia, South Korea, Italy, and others ensured the agenda remained robust.
South Africa’s presidency centered its agenda on solidarity, equality, and sustainable development, with an emphasis on elevating the needs and priorities of the Global South.
Two key areas emerged as potentially transformative:
1. Enhanced climate action commitments
2. A renewed push for debt relief among developing economies
Climate Actions: A Defining Priority
The climate crisis dominated discussions, especially as African and other developing nations urged wealthier countries to dramatically increase action and funding. The year 2025 is set to become the second or third warmest ever recorded, with January 2025 being the hottest January in history — a stark signal of accelerating global warming.
Reaffirming the Paris Agreement
G20 leaders renewed their commitment to the Paris Agreement objectives:
- Keeping global temperature rise well below 2°C, with efforts toward 1.5°C
- Recognizing equity and common but differentiated responsibilities
- Pursuing net-zero or carbon-neutral pathways by mid-century, aligned with national circumstances
- Ensuring transitions are just, equitable, and supportive of poverty reduction
Adaptation, Resilience, and Early Warning Systems
The summit underscored the need to integrate climate adaptation into national policies. Leaders reaffirmed implementation of the UAE Framework for Global Climate Resilience, pushing for:
- Wider availability of early warning systems
- Stronger disaster risk reduction programs
- Focused support for regions highly vulnerable to climate shocks — notably in Africa
Financing Climate Action
Developing nations require an estimated $5.8–5.9 trillion before 2030 to meet their Nationally Determined Contributions (NDCs). The G20 highlighted outcomes from COP30 in Belém, Brazil, calling for:
- Alignment of financial systems with low-emission development
- Support for technology transfer on voluntary terms
- Greater capacity building for climate-vulnerable states
African climate justice groups, in an open letter, pushed G20 leaders to go further — urging fossil fuel phaseout commitments and demanding fair, inclusive energy transitions.
Debt Relief for Developing Economies: A Growing Global Crisis
High public debt in developing nations formed the second major pillar of the summit. Many of these countries now spend alarming portions of government revenue on interest payments — diverting funds from essential needs like healthcare, infrastructure, and education.
The Numbers Tell the Story
Recent UN figures show:
- $921 billion in net interest payments by developing countries in 2024 — a 10% increase from 2023
- $1.4 trillion in external debt servicing for developing economies in 2023
- 38% of developing countries (nearly half in Africa) spend over 10% of government revenue on interest alone
- Interest payments for low-income African nations have doubled over the past decade
G20 Leaders Endorse New Debt Sustainability Measures
Leaders formally adopted the Ministerial Declaration on Debt Sustainability from the October 2025 Finance Ministers’ meeting, supporting:
- Strengthening the G20 Common Framework beyond the DSSI
- Faster, more predictable, coordinated debt treatment processes
- Improved debt transparency from all creditors — including private lenders
- Review and enhancement of the IMF–World Bank Debt Sustainability Framework for low-income countries
Voices from Developing Nations
Several leaders made urgent appeals:
- Ethiopian Prime Minister Abiy Ahmed stressed that meaningful debt restructuring is essential for human-centered development.
- Namibian President Netumbo Nandi-Ndaitwah highlighted unfair financing perceptions, noting Namibia repaid a $750 million bond yet still carries high-risk ratings.
These concerns reinforced a consensus: high debt is a direct barrier to inclusive and sustainable growth, particularly across Africa.
A Step Toward a More Equitable Global Order?
The G20’s decisions on climate and debt relief signal a pivot toward a more balanced global system — one that attempts to prioritize developing nations rather than treating them as an afterthought.
Still, enormous challenges persist:
- Implementation depends heavily on follow-through
- Clear financing mechanisms must be defined
- Future leadership — may influence the trajectory
Despite the U.S. boycott, the adopted declaration stands as a statement of international resolve.
