What is India's pathway to limit global warming to 1.5°C?
Industry

Decarbonising the industry sector
India’s industrial sector is a major component of its national emissions profile, accounting for more than 26% of total emissions when energy use and process emissions are combined. Energy-related industrial CO₂ emissions were about 736 MtCO₂ in 2024, while process emissions reached 337 MtCO₂e. Industrial energy demand remains heavily dependent on fossil fuels, with more than 60% supplied by coal, oil, and gas.
Emissions are concentrated in basic materials production. Iron and steel is the largest industrial emitter, responsible for around 10–12% of national emissions due to coal-based production and increasing output.1 Cement, chemicals and oil refineries are also major contributors — cement due to high heat demand and process emissions, and chemicals due to energy-intensive processes and feedstock emissions, particularly for ammonia and refining hydrogen from fossil gas.2

Fuel shares include both energy and non-energy use (eg. the use of oil to generate heat for industry use and as a feedstock to produce products such as plastics).

Reducing emissions in line with 1.5°C requires structural shifts in energy use and production processes. Coal use in industry falls rapidly, from 33% of final energy in 2023 to below 1% by 2040 and is fully phased out by 2050. Electrification expands steadily, reaching 45% by 2040 and 55% by 2050, maintaining similar levels until 2070. However, total industrial energy demand grows over this period, which is consistent with industrial output expansion, underscoring the importance of accelerating energy efficiency and circularity in this sector.
Process emissions remain a key residual challenge even as energy decarbonises. They increase to 377 MtCO₂e by 2030 and decline only to 226 MtCO₂e by 2050, making them the dominant remaining source of industrial emissions. Addressing these emissions will require material efficiency, clinker substitution in cement, low-emissions steel routes, and targeted deployment of capture technologies.
Green hydrogen plays a central enabling role as a replacement feedstock in ammonia and refining, a reducing agent in steel production, and a high-temperature energy source where electrification is limited. A switch for the conventional business-as-usual (BAU) grey ammonia pathway to a real zero pathway that uses renewable electricity to produce green ammonia is crucial. States with high renewable energy production capacity, such as Rajasthan and Gujarat would be able to produce green ammonia on pay parity levelised cost of ammonia (LCOA) with BAU ammonia.
India’s National Green Hydrogen Mission, targeting production of at least 5 Mt per year by 2030, provides an early policy foundation, alongside broader efforts to accelerate electrification, phase out coal, and support low-emissions industrial production.

Fuel shares include both energy and non-energy use (eg. the use of oil to generate heat for industry use and as a feedstock to produce products such as plastics).
Direct CO₂ emissions only are considered (see power sector analysis, hydrogen and heat emissions are not considered here). All values are rounded. Year of full decarbonisation is based on a carbon intensity threshold of 5gCO₂/MJ.
