Introduction
Climate change stands as a defining issue of the 21st century, influencing weather patterns, threatening food security, increasing natural disasters, and exacerbating global inequalities. As a collective of the world’s largest economies, the G20’s contribution is critical to achieving global climate goals. Since the early 2000s, the G20 has progressively incorporated climate change into its agenda, recognizing its interconnectedness with economic stability and global development. The G20’s leadership is instrumental due to its economic leverage and technological capacities, yet divergent national interests, economic dependencies on fossil fuels, and varying stages of development among its members often hinder unified action.
Climate change is a global issue that affects all countries, including India, which is one of the world’s largest emitters of greenhouse gases. The G20 is a group of the world’s largest economies, including India, and plays a crucial role in addressing climate change on a global scale. India has committed to reducing its carbon emissions intensity, which is the amount of carbon dioxide emitted per unit of GDP, by 33-35% below 2005 levels by 2030. India has also pledged to achieve 40% of its energy from non-fossil fuel sources by 2030.
Understanding the G20’s effectiveness in driving climate action requires a nuanced exploration of its policies, political dynamics, and practical outcomes. By examining past initiatives, current commitments, and future possibilities, this paper seeks to elucidate how the G20 can transition from pledges to tangible impact, ensuring a resilient and sustainable future.
Determinants of Climate Change
Climate change is a complex phenomenon that is caused by a combination of natural and human factors. Here are some of the key determinants of climate change:
- Greenhouse gas emissions: The most significant driver of climate change is the emission of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide. These gases trap heat in the atmosphere and contribute to the warming of the planet.
- Deforestation: Trees absorb carbon dioxide from the atmosphere, so deforestation reduces the amount of carbon dioxide that can be removed from the air. Deforestation also contributes to soil erosion, which can lead to the release of additional carbon into the atmosphere.
- Industrialization: Industrial activities, such as burning fossil fuels for energy and transportation, release large amounts of greenhouse gases into the atmosphere.
- Agricultural practices: Agriculture is a significant source of greenhouse gas emissions, primarily due to the production of methane by livestock and the use of synthetic fertilizers.
- Land use changes: Changes in land use, such as urbanization and the conversion of forests to farmland, can affect the amount of carbon that is absorbed or released by the land.
- Natural factors: Natural factors such as volcanic activity, solar radiation, and changes in Earth’s orbit can also contribute to changes in the climate.
Laws/Policies regarding Climate Change
Climate change is a global problem that requires collective action and coordinated policy responses from governments around the world. Here are some of the key laws and policies that have been implemented to address climate change:
- Paris Agreement: The Paris Agreement is a global treaty that was adopted in 2015, which aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels, and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. The agreement includes commitments from all countries to reduce their greenhouse gas emissions and to regularly report on their progress.
- Clean Air Act (United States): The Clean Air Act is a federal law in the United States that regulates air emissions from both stationary and mobile sources. The law has been used to regulate greenhouse gas emissions, including carbon dioxide.
- Renewable Energy Directive (European Union): The Renewable Energy Directive is a directive of the European Union that sets binding renewable energy targets for each member state. The directive also establishes sustainability criteria for biofuels and bioliquids.
- Carbon Tax (Canada): Canada implemented a federal carbon tax in 2019, which applies to provinces that do not have their own carbon pricing systems. The tax is intended to provide an economic incentive to reduce greenhouse gas emissions.
- National Adaptation Plan (India): India has developed a National Adaptation Plan to address the impacts of climate change on key sectors such as agriculture, water, and forests. The plan includes measures to increase resilience and adaptation capacity in these sectors.
Literature Review
The importance of the G20 in climate governance has been addressed extensively in recent scholarship. Falkner (2016) posits that while the G20 lacks formal treaty-making authority, its agenda-setting power significantly influences global climate efforts. The informal structure allows flexibility but can also dilute binding commitments.
Börzel and Risse (2018) argue that the G20’s decision-making by consensus often leads to compromises that weaken ambitious climate policies. The Climate Transparency (2023) reports highlight inconsistencies between G20 declarations and national actions, emphasizing the persistent reliance on fossil fuels.
Kanie and Biermann (2017) introduce the concept of ‘governance through goals,’ where the G20 can catalyze collective climate action by setting clear targets. However, the literature suggests that setting goals without accountability frameworks results in minimal enforcement. Furthermore, the IPCC (2023) underscores the need for accelerated emissions reductions, directly implicating the G20 in meeting global temperature targets.
Recent analyses show that while initiatives like the “G20 Climate and Energy Action Plan for Growth” and “Mission Innovation” have promoted research and collaboration, they fall short in creating binding financial commitments or carbon pricing frameworks.
Thus, literature stresses a dual necessity: the G20 must enhance coherence between economic and climate policies while strengthening mechanisms for transparency and accountability.

Conclusion
The G20 holds unparalleled influence in shaping the global response to climate change. While progress has been made in raising awareness and initiating policy frameworks, substantial gaps between ambition and action persist. By strengthening accountability, fostering innovation, and promoting inclusive governance, the G20 can transform into a true leader in the global climate fight. The stakes are high, and the time for transformative action is now. The findings of this research reveal that while the G20 is moving in the right direction, substantial gaps remain in terms of climate finance delivery, technological transfers to developing nations, policy coherence, and public engagement. Addressing these challenges demands greater accountability mechanisms, integration of climate objectives into core economic strategies, and the mainstreaming of climate resilience across all sectors of governance.
Ultimately, the G20 must evolve from being a platform for dialogue into a force for transformative action. Only by aligning economic ambitions with environmental imperatives, fostering genuine North-South cooperation, and ensuring transparency and fairness in decision-making can the G20 truly lead the world towards a sustainable, climate-resilient future. The window for effective action is narrowing, and the G20’s choices in the coming years will significantly shape the fate of the global climate agenda
