The automotive industry is one of the leading contributors to global CO₂ emissions, not only through vehicle usage but also across manufacturing, supply chains, and energy-intensive production processes.
As production volumes grow and mobility demand increases, emissions linked to automotive operations continue to rise.
Today, automotive manufacturers face huge pressure from governments, global climate organizations, and corporate ESG goals to reduce their carbon footprint in a measurable and transparent manner.
Now, emission reduction is no longer a long-term ambition—it is an immediate business requirement.
Trigen DC is a manufacturer of high-efficiency industrial heat pumps designed for automotive and auto-ancillary manufacturing processes. These heat pumps directly reduce fuel and energy consumption by replacing conventional boilers, electric heaters, and steam-based heating systems used in automotive plants.
CO₂ emissions in the automotive industry originate from multiple stages of the value chain:
Manufacturing plants: High energy consumption for assembly lines, painting processes, heat treatment, and utilities.
Supply chain and logistics: Emissions from raw material sourcing, component transportation, and warehousing.
Vehicle usage lifecycle: Fuel combustion or electricity generation linked to vehicle operation.
Waste and inefficiencies: Energy losses, scrap materials, idle machinery, and suboptimal processes.
In automotive manufacturing, a significant share of CO₂ emissions originates from process heating requirements across paint shops, surface treatment lines, washing and degreasing systems, phosphating, rinsing, baking, and hot water generation. These processes typically operate within temperature ranges of 60°C to 140°C and are traditionally powered by fuel-fired boilers or electric heaters.
Under the greenhouse gas Protocol, automotive emissions are categorised as:
Automotive companies often struggle with Scope 1 & Scope 2 emissions due to limited data visibility, supplier dependency, and lack of standardised reporting mechanisms—yet these typically account for the largest share of total emissions.
Automotive companies operate under increasingly strict regulatory frameworks across regions such as the EU, India, and the US. Emission norms, OEM sustainability mandates, and carbon disclosure requirements are becoming more detailed and enforceable.
In parallel, many manufacturers have committed to net-zero targets, requiring accurate carbon accounting and continuous reduction across operations. Investors, customers, and OEM partners now expect transparent ESG reporting backed by real data.
Failure to execute can result in regulatory penalties, restricted market access, reputational damage, and weakened investor confidence. As a result, decarbonisation is now a strategic priority rather than a compliance exercise.
Despite strong intent, automotive companies face several practical challenges:
These challenges highlight the need for intelligent, integrated, and scalable solutions rather than isolated initiatives.
Trigen’s primary decarbonisation approach focuses on direct process heat transformation rather than monitoring alone. By deploying industrial heat pumps at the process level, Trigen enables immediate fuel reduction, improved energy efficiency, and reduced CO₂ emissions within core automotive manufacturing operations.

These challenges highlight the need for intelligent, integrated, and scalable solutions rather than isolated initiatives.
Trigen’s approach is built on clear principles:
Trigen heat pumps are deployed across critical automotive processes such as paint shop, degreasing, phosphating, surface treatment, washing and cleaning systems, LPG vaporizers, boiler feed water heating, and low-pressure steam generation. These applications allow recovery and reuse of waste heat while delivering consistent process temperatures with significantly lower energy input.
Trigen enables automotive applications to monitor and optimise energy usage in real time through smart energy management systems, machine-driven analytics help identify inefficiencies, peak consumption patterns, and opportunities to reduce dependency on fossil fuels—leading to lower emissions and controlled energy costs.
Using digital twin technology, Trigen simulates plant operations to analyse performance under different conditions. This helps manufacturers identify emission hotspots, predict inefficiencies, and take corrective actions before issues escalate—reducing waste and unnecessary energy consumption.
Trigen supports sustainable manufacturing by optimising production processes, enabling heat recovery, and promoting energy reuse. Low-carbon production planning ensures that sustainability is embedded into daily operations rather than treated as a parallel initiative.
Trigen provides tools for tracking and managing supplier emissions across the automotive supply chain. With improved data transparency, standardised reporting, and collaboration platforms, manufacturers gain better control over Scope 3 emissions and supplier sustainability performance.
Automotive manufacturers deploying Trigen heat pump solutions have achieved energy savings ranging from 30% to 70% compared to traditional heating methods, along with significant fuel cost reduction and improved process efficiency across multiple applications.
Automotive organisations using Trigen’s solutions have achieved:
These outcomes demonstrate how structured, data-driven sustainability initiatives can deliver both environmental and business value.
Beyond emission reduction, Trigen delivers broader business benefits:
Sustainability becomes a growth enabler rather than a cost centre.
Trigen DC is India’s only manufacturer of high-temperature heat pumps capable of operating up to 145°C, with successful commercial deployments including ultra-low ambient heat pumps operating at −35°C. Trigen’s solutions are backed by over five years of IIT Madras research and deployed across multiple automotive manufacturing facilities.
Automotive manufacturers choose Trigen for its:
