It involves identifying and tracking government expenditures and revenues that have environmental implications. This means looking at how much money is spent on pollution control, renewable energy subsidies, conservation efforts, or conversely, how much revenue is generated from environmental taxes or fines. The goal is to make these financial flows visible and understandable.

Governments using a green budget approach often conduct an 'environmental fiscal reform'. This involves reorienting subsidies away from environmentally harmful activities (like fossil fuel subsidies) towards green initiatives (like solar power incentives). It also includes implementing or strengthening environmental taxes, such as carbon taxes or taxes on plastic, to discourage polluting behaviour.

A key aspect is the integration of environmental objectives into the mainstream budget process. Instead of treating environmental protection as a separate, marginal issue, it becomes a core consideration in all spending decisions. For instance, when planning a new highway, a green budget approach would require assessing its impact on biodiversity, water resources, and air quality, and potentially allocating funds for mitigation measures.

It often involves setting specific, measurable targets for environmental outcomes linked to the budget. For example, a government might set a target to reduce greenhouse gas emissions by 5% through budget allocations for renewable energy projects and energy efficiency programs within a fiscal year.

Green budgeting differs from traditional budgeting by explicitly accounting for the environmental externalities of economic activities. Traditional budgets focus on financial costs and benefits, often ignoring the 'hidden' costs of pollution, resource depletion, or climate change impacts. Green budgeting attempts to bring these externalities into the financial calculus.

One challenge is the lack of standardized methodologies for measuring and reporting environmental impacts across different sectors and countries. This can make it difficult to compare the effectiveness of green budgeting efforts or to aggregate environmental performance at a national level.

In practice, a government might allocate funds for a new metro line, but a green budget perspective would also earmark money for tree plantation along the route, noise reduction measures, and ensuring the metro runs on renewable energy, thereby minimizing its environmental footprint.

In 2023, the International Monetary Fund (IMF) released updated guidance on green budgeting, encouraging member countries to adopt such frameworks to support climate action and sustainable development, highlighting its growing importance in global economic policy.

India's Union Budget 2023-24, for instance, included several 'green growth' initiatives, such as promoting green hydrogen, energy transition, and energy storage, alongside allocations for climate adaptation and mitigation, reflecting an increasing adoption of green budgeting principles.

For UPSC, examiners test the understanding of how fiscal policy can be used as a tool for environmental protection and sustainable development. They look for clarity on what green budgeting entails, its objectives, practical implementation challenges, and its role in achieving national and international climate commitments. Candidates are expected to link it with economic growth and environmental sustainability.
