Climate change is entering a decisive phase. Governments, international institutions, financial organizations and businesses are under growing pressure to turn climate commitments into measurable emissions cuts, clean-energy investment and stronger adaptation measures.
Recent developments under the Paris Agreement, including the outcomes of COP29 in Baku and COP30 in Belém, have placed climate finance, renewable energy, adaptation and implementation at the center of international efforts. Yet the latest scientific assessments show that current policies remain insufficient to keep global warming safely within the Paris Agreement’s goals.
Quick Facts
- COP29 agreed to raise the annual climate-finance goal for developing countries to $300 billion by 2035, while calling for efforts to scale total finance from public and private sources to $1.3 trillion annually by 2035.
- COP30 adopted the Belém Adaptation Indicators, creating a common framework for tracking progress toward the global adaptation goal.
- COP30 also called for tripling adaptation finance by 2035, reflecting the growing financial burden of climate impacts on vulnerable countries.
- The UNEP Emissions Gap Report 2025 estimates that full implementation of current nationally determined contributions (NDCs) would still lead to around 2.3–2.5°C of warming this century, while current policies point to about 2.8°C.
- Global energy investment is shifting toward low-carbon technologies: the IEA estimated that $2.2 trillion would go to clean-energy areas in 2025, roughly twice the $1.1 trillion directed toward oil, gas and coal.
- The IEA expects global renewable power capacity to increase by about 4,600 GW by 2030, with solar photovoltaic technology accounting for almost 80% of the projected expansion.
Key Research Findings
The evidence points to a clear conclusion: international climate cooperation is expanding, but the pace of implementation remains too slow.
The latest UNEP assessment shows that new climate pledges have narrowed projected warming only slightly. Even if countries fully implement their NDCs, the world remains far from the Paris Agreement’s ambition of holding warming well below 2°C while pursuing efforts to limit it to 1.5°C.
At the same time, the energy transition is accelerating. Investment in renewable energy, electricity grids, storage, electrification and other clean technologies is growing rapidly, demonstrating that many of the technologies required for decarbonization are already commercially available.
The central challenge is therefore no longer simply developing solutions. It is deploying them quickly, financing them fairly and ensuring that national policies deliver the reductions promised internationally.
What Are the New International Efforts to Combat Climate Change?
1. Scaling Up Climate Finance
Climate finance has become one of the most important elements of international climate negotiations.
At COP29 in Baku in 2024, countries agreed to a new finance goal that calls for developed countries to lead efforts to provide $300 billion per year to developing countries by 2035. The agreement also calls for all actors to work toward scaling climate finance from public and private sources to at least $1.3 trillion per year by 2035.
The subsequent Baku-to-Belém Roadmap was designed to identify practical ways of reaching that larger financing target. Its approach includes expanding concessional finance, using innovative financial instruments, reducing debt pressures and attracting more private investment.
This matters because many developing countries face two problems at once: escalating climate risks and limited fiscal space to invest in resilience and clean infrastructure.
2. Strengthening Climate Adaptation
Reducing greenhouse gas emissions is essential, but countries must also prepare for climate impacts that are already occurring.
The COP30 outcome in Belém strengthened the international adaptation framework by adopting the Belém Adaptation Indicators. These indicators are intended to provide a common basis for assessing progress toward the global goal on adaptation.
Finance remains a major obstacle. UNEP estimates that developing countries could require between $310 billion and $365 billion per year for adaptation by 2035, while international public adaptation finance was only $26 billion in 2023.
The gap illustrates why adaptation finance is increasingly treated as a core component of global climate policy rather than a secondary issue.
3. Accelerating the Renewable Energy Transition
Renewable energy is another major pillar of international climate action.
At COP28, governments called for efforts to triple global renewable-energy capacity and double the rate of energy-efficiency improvements by 2030. The agreement also called for accelerating the transition away from fossil fuels in energy systems.
The direction of travel has since been reinforced by market trends. According to the IEA, renewable power capacity is expected to expand by around 4,600 GW between 2025 and 2030, with solar PV responsible for most of the increase.
However, rapid renewable deployment also creates new challenges, including:
- Electric-grid expansion and modernization
- Energy storage
- Critical-mineral supply chains
- Access to affordable finance
- Integration of variable renewable power
- Workforce and skills development
The next stage of the energy transition will therefore require not only more solar panels and wind turbines, but also stronger infrastructure and coordinated international investment.
4. Stronger National Climate Plans
The Paris Agreement relies heavily on Nationally Determined Contributions (NDCs)—national climate plans that countries periodically update to reflect greater ambition.
The latest UNEP analysis, however, shows a significant gap between current commitments and the emissions reductions needed to meet the Paris temperature goals. UNEP estimates that annual emissions in 2035 would need to be 35% below 2019 levels for a 2°C pathway and 55% below 2019 levels for a 1.5°C pathway.
This makes the implementation of NDCs increasingly important. Governments must translate broad targets into policies affecting electricity generation, transportation, buildings, industry, agriculture, land use and investment.
A climate target without implementation, financing and monitoring has limited value.
5. Addressing Loss and Damage
Some climate impacts cannot be prevented entirely through mitigation or adaptation. For vulnerable countries, this has increased the importance of loss and damage finance.
COP28 in Dubai helped operationalize funding arrangements for addressing loss and damage, including a dedicated fund under the UN climate process.
The issue remains closely connected to climate justice. Countries that have contributed relatively little to historical greenhouse gas emissions can face severe economic and social consequences from droughts, floods, storms, sea-level rise and other climate hazards.
International cooperation is therefore increasingly focused not only on reducing future emissions but also on helping vulnerable communities cope with unavoidable impacts.
Major Results and Main Drivers
The newest international climate efforts are being driven by several interconnected factors.
Rising Climate Risks
More frequent and severe climate impacts are increasing pressure on governments to strengthen both mitigation and adaptation.
Falling Clean-Energy Costs
The growing competitiveness of solar, wind and other low-carbon technologies is making the energy transition increasingly attractive from an economic as well as environmental perspective.
Growing Investment
Clean-energy investment is now substantially larger than investment in fossil-fuel supply, according to the IEA’s 2025 analysis.
Climate Finance Inequality
Developing economies often face higher borrowing costs and greater exposure to climate risks, making international financial support critical to accelerating their transition.
Pressure for Greater Accountability
As climate pledges accumulate, international institutions are placing greater emphasis on transparency, implementation and measurable results rather than commitments alone.

What Happens Next?
The most important question is whether international commitments will translate into real-world emissions reductions.
The answer will depend on several priorities:
- Governments must implement stronger national climate policies.
- Financial institutions must make climate investment more accessible and affordable.
- Developed countries must increase support for developing economies.
- Renewable energy and electricity infrastructure must be deployed faster.
- Adaptation investment must rise alongside mitigation spending.
- Climate commitments must be tracked through transparent and credible reporting.
The Baku-to-Belém Roadmap has shifted attention toward implementation of the $1.3 trillion climate-finance ambition. In June 2026, UN Climate Change officials continued to emphasize the need to turn this roadmap into practical financial flows capable of supporting climate action in developing countries.
The Bottom Line
New international efforts to combat climate change are creating stronger financial mechanisms, adaptation frameworks and clean-energy targets—but the world remains off track.
The latest scientific evidence shows that existing commitments are not sufficient to meet the Paris Agreement’s temperature goals. At the same time, the rapid expansion of renewable energy and the growth of clean-energy investment demonstrate that practical solutions are available.
The defining issue for the coming years will therefore be implementation. International climate diplomacy can establish targets and financing frameworks, but governments, investors and institutions must convert those commitments into lower emissions, stronger infrastructure and greater resilience.
If international cooperation succeeds in closing the gap between ambition and action, the benefits will extend beyond climate protection. Cleaner air, greater energy security, new investment, stronger infrastructure and more resilient economies can all become part of the same transition.
The climate challenge is global, but so is the opportunity to respond.
