Net Zero Commitments — Definition
Definition
Net zero commitments represent a country's pledge to achieve a balance between the amount of greenhouse gases emitted and the amount removed from the atmosphere by a specific target date. This concept has become the cornerstone of global climate action, with over 130 countries having announced net zero targets as of 2024.
For India, this commitment translates to achieving net zero emissions by 2070, as announced by Prime Minister Narendra Modi at COP26 in Glasgow in 2021. Understanding net zero is crucial for UPSC aspirants as it intersects multiple dimensions of governance, international relations, and sustainable development.
The concept differs from 'carbon neutrality' in its scope - while carbon neutrality focuses only on carbon dioxide, net zero encompasses all greenhouse gases including methane, nitrous oxide, and fluorinated gases.
The 'net' in net zero acknowledges that some emissions may continue but must be balanced by equivalent removals through natural sinks like forests or technological solutions like carbon capture and storage.
India's net zero commitment is particularly significant given its status as the world's third-largest emitter of greenhouse gases, yet with per capita emissions well below the global average. The commitment reflects India's balancing act between development imperatives and climate responsibilities.
The pathway to net zero involves massive transformations across all sectors of the economy - from energy and transport to industry and agriculture. For the energy sector, this means transitioning from fossil fuels to renewable sources like solar, wind, and green hydrogen.
The industrial sector must adopt cleaner technologies and improve energy efficiency. Agriculture needs sustainable practices that reduce methane emissions while maintaining food security. The transport sector requires electrification and modal shifts.
Achieving net zero also demands significant financial resources, estimated at $10.1 trillion for India according to various studies. This has implications for climate finance negotiations and international cooperation.
The commitment also raises questions about climate justice and the principle of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC), which India has consistently advocated.
From a UPSC perspective, net zero commitments connect to multiple areas: environmental governance, international relations, economic policy, and constitutional provisions. Questions can emerge from various angles - India's climate diplomacy, sectoral decarbonization strategies, financing mechanisms, technological pathways, and the balance between development and environmental protection.
The topic also links to current affairs through COP meetings, policy announcements, and international climate negotiations.
