Background and Context

What is a Biennial Update Report

Function and scope of BURs submitted by non-Annex I parties to the UNFCCC.

• Purpose: provide updated national GHG inventories, mitigation actions and information on needs in finance, technology and capacity building.
• Reporting cycle: BURs are usually submitted every two years, complementing National Communications and NDC updates.
• Audience: UNFCCC secretariat, other parties, researchers and international funders who use the data for synthesis reports and negotiations.
• MRV role: strengthen transparency through documented methodologies, uncertainty assessment and institutional arrangements for measurement, reporting and verification.
• Comparability limits: methodologies and data availability vary among countries; land-use accounting poses special challenges.

Key findings in India’s BUR-4

Quantitative and sectoral highlights from the 2020 inventory and related notes.

• Total emissions (ex-LULUCF) reported at 2,959 Mt CO2e for 2020; net emissions including LULUCF at 2,437 Mt CO2e.
• 2020 drop: total GHG emissions decreased by 7.93% compared to 2019, influenced by pandemic-related activity changes and structural factors.
• Sectoral shares: energy 75.66%, agriculture 13.72%, industrial processes 8.06%, waste 2.56%.
• LULUCF sequestration: ~522 Mt CO2 sequestered, equivalent to roughly 22% of the country’s CO2 emissions in 2020.
• Intensity gains: GHG emission intensity of GDP reduced by 36% since 2005.

Methodology and inventory issues

How India compiles GHG inventories and challenges specific to national reporting.

• IPCC guidelines: India uses IPCC Tiered approaches for sectors, mixing activity data and emission factors to estimate emissions.
• Data sources: national statistics, energy consumption datasets, industrial production figures and forestry assessments feed the inventory.
• Uncertainty: sectoral uncertainties are documented; LULUCF estimates are sensitive to land-use classification and biomass assessment methods.
• Temporal comparability: national time series depend on methodological consistency; revisions may occur when improved data become available.
• Capacity gaps: need for finer spatial data, national emission factors and improved monitoring for distributed sources like small combustion and agriculture.

India's mitigation actions reported

Overview of policies and programmes cited in BUR-4 as contributing to mitigation.

• Renewable energy expansion: large-scale deployment of solar and wind capacity and supportive policies like RPOs and auctions.
• Energy efficiency: standards and labelling, Perform Achieve and Trade (PAT) scheme and appliance efficiency programmes.
• Electrification and clean cooking: household electrification, Ujjwala LPG connections and efforts to reduce biomass burning.
• Forestry and restoration: national afforestation programmes and landscape restoration contributing to LULUCF sinks.
• Transport shifts: policies promoting public transport, vehicle fuel efficiency and gradual electrification of mobility.

Finance, technology and capacity-building needs

What BUR-4 reports about India’s constraints and support requirements for implementation.

• Finance gaps: need for concessional and climate-focused finance to scale low-carbon infrastructure and adaptation measures.
• Technology needs: access to advanced renewable integration, storage technologies and climate-smart agricultural practices.
• Capacity building: strengthening state-level MRV, sectoral modelling and local institutions for project implementation.
• Private sector role: mobilising domestic capital and blended finance to reduce reliance on external funding alone.
• International cooperation: emphasis on technology transfer, joint R&D and targeted capacity support under UNFCCC mechanisms.

Implications for global climate diplomacy

How the BUR affects India’s positioning in international negotiations and multilateral processes.

• Credibility: a transparent inventory supports India’s negotiating stance that action aligns with development priorities and equity considerations.
• Negotiation leverage: documented needs in finance and technology underpin requests for support and collaboration.
