Climate change poses an unprecedented global crisis driven by greenhouse gas emissions from human activities like burning fossil fuels, deforestation, and intensive agriculture. As climate impacts intensify worldwide, international cooperation is essential to curb emissions and adapt to current and future effects. Since the 1990s, nations have come together through major treaties and accords for climate mitigation and resilience.
The Need for Collective Global Action
Climate change is a uniquely complex threat. Greenhouse gases mix uniformly in the atmosphere, meaning emissions everywhere raise risks. Impacts like rising sea levels and extreme weather also transcend borders. These realities make climate a global commons challenge requiring unified action across nations to tackle climate change. We must work collaboratively to mitigate emissions, adapt to unavoidable impacts, and provide support to vulnerable communities.
- Transition rapidly away from carbon-intensive energy and activities
- Mobilize financing mechanisms to support lower-income countries
- Build climate resilience and adaptation, especially for vulnerable regions
- Develop equitable solutions that align technology, policy and society
While each country has a role, binding international agreements help assure unified commitments critical to tackling climate change. Treaties also signal global priorities for policy, technology, and investment across public and private sectors.
Major International Agreements to Tackle Climate Change
Several landmark accords have formed the backbone of global climate cooperation since the 1990s, providing frameworks for unified action across borders that remain essential if we hope to tackle climate change through aggressive mitigation, adaptation support worldwide, and vulnerable community assistance. But continued expansion of climate commitments is crucial.
The UN Framework Convention on Climate Change (UNFCCC) – 1992
- Signed by 154 nations at the Rio Earth Summit
- Established a common objective to stabilize greenhouse gas concentrations
- Called for climate policies based on equity and common but differentiated responsibilities
- Created guidelines for reporting and monitoring emissions
- This Led to subsequent binding accords like the Kyoto Protocol and Paris Agreement
The Kyoto Protocol – 1997
- Extended the UNFCCC with legally binding emissions limits
- Set targets for industrialized nations based on differentiated responsibilities
- Established carbon trading mechanisms like emissions trading and the Clean Development Mechanism
- Advanced greenhouse gas monitoring and accounting standards
The Copenhagen Accord – 2009
- Pledged mobilization of $100 billion annually by 2020 for developing nations
- Established maximum two °C global temperature increase target above pre-industrial levels
- Called for mitigation action based on differentiated national capabilities
- Laid groundwork for a consensus model of future agreements
The Paris Agreement – 2015
- Committed 196 nations to limiting global warming to well under two °C, aiming for 1.5°C
- Established binding obligations by parties to submit emissions reduction plans and progress reports
- Embedded principles of equity and common but differentiated responsibilities
- Delivered framework for ratcheting up ambition and strengthening targets over time
While imperfect, these accords have driven increasing climate action and cooperation. But a more urgent, ambitious effort is still needed to align with the latest climate science and keep warming below catastrophic levels.
The Sharm El-Sheikh Agreement – 2022
- The Historic Loss and Damage Fund was established to help vulnerable countries, but funding details are unclear
- No major new agreements on increasing emissions cuts before 2030
- Deal reached to help developing countries transition to clean energy, but the plan lacks specifics
- Tougher annual reporting rules set around emissions progress to pressure nations
- No new pledges to expand action on phasing down fossil fuels, angering some parties
- Overall, limited progress has been made on urgent mitigation needed this decade to meet the 1.5C goal
- COP27 first-time loss and damage recognized as separate climate issue for compensation
- Lack of momentum leaves big question if countries will commit more at next year’s COP28
The main achievements were around loss and damage funding and reporting rules, while critical areas like mitigation ambition and fossil fuel phase-down showed little advancement. This further pressures nations to step up commitments before time runs out to tackle climate change by limiting warming to 1.5°C. Countries must urgently increase pledges to cut emissions faster this decade and phase out all fossil fuels if we hope to meet this critical goal..

|Emissions pledges from all parties, 1.5°C warming limit, ambition ratcheting
|Loss and damage fund was established
Challenges and Breakthroughs
Pursuing consensus between nearly 200 diverse nations has inevitably posed challenges:
- Inadequate emissions reduction commitments and lack of enforcement mechanisms
- Slow ratification and implementation by some parties
- Disagreements over equity principles and climate financing
- Changes in political leadership undermining momentum
However, international agreements have also delivered breakthroughs:
- Established global GHG mitigation objectives and emissions reporting standards
- Mobilized >$500 billion in climate financing for developing countries
- Catalyzed growth of carbon pricing and clean energy
- Built institutions like the IPCC, UNFCCC and Green Climate Fund
- Aligned societies worldwide around the urgency of climate action
They provide an imperfect but essential foundation for ongoing collaboration to strengthen targets and quicken the pace of change.
Are International Agreements Effective?
While the pace of implementation remains insufficient, international climate accords have had demonstrable positive impacts:
- Emissions Measurement & Planning – Agreements have mandated standardized greenhouse gas inventories and modelling, clarifying reduction pathways.
- Clean Energy Investment – Legal frameworks guide policy and provide market signals that have accelerated renewable energy deployment over 5-fold since 2000.
- Carbon Pricing – Emissions trading provisions have informed carbon markets covering over 20% of global emissions.
- Climate Finance – $500 billion has been directed to developing nations via funds like the Green Climate Fund.
- Technology Sharing – Cooperative mechanisms foster innovation transfer and diffusion of emissions-reducing technologies worldwide.
- Public Support – Treaties raise public awareness and government mandates for climate mitigation across societies.
While more transformational action is urgently required, international agreements have laid the groundwork and strengthened ambition over time. Ongoing collaboration focused on equitable solutions remains our best pathway to climate stability. By continuing to tackle climate change together through just transitions, supportive climate financing, and increasingly ambitious emissions reductions, we can achieve a livable future.
Frequently Asked Questions
What are the main differences between agreements like Kyoto and Paris?
Kyoto legally mandated emissions cuts for developed nations only, while Paris established voluntary pledges by all parties with collective long-term temperature goals.
What are some key equity debates in climate agreements?
Key issues include climate financing support for developing nations and differentiated responsibilities for emissions reductions based on countries’ relative contributions and capabilities.
Which countries have been barriers to progress on agreements?
Shifting political priorities in nations like the U.S. and Russia have posed challenges. But most nations have constructively participated.
