The Path to Decarbonizing the Chemical Industry: A Strategic Blueprint

The chemical industry, a significant contributor to global CO2 emissions, faces immense pressure to decarbonize. This blog delves into a strategic blueprint for decarbonizing the chemical industry from 2020 to 2030, highlighting critical avenues, stakeholders, and potential impacts.


The chemical industry produces essential materials and products ranging from fertilizers to plastics. However, this industry’s operations are heavily reliant on fossil fuels, making it a significant contributor to global greenhouse gas emissions. Annually, the production of primary chemicals alone emits about 1 billion tons of CO2, with additional emissions from processes such as hydrogen production for ammonia, pushing the total to approximately 1.35 billion tons. When considering emissions from related upstream and downstream activities, as well as post-use disposal, the industry’s total CO2 emissions exceed 3 billion tons annually, accounting for around 2.5% of global emissions. Decarbonization in this context means implementing strategies and technologies that reduce carbon emissions without compromising industrial growth.

Challenges in Decarbonization

  • A significant portion of emissions arises from the production of basic chemicals such as ammonia, ethylene, and methanol.
  • Ammonia production alone contributes about 500 million tons of CO2 annually, primarily due to the Haber-Bosch process, which requires substantial fossil fuel-based energy.
  • Ethylene and polypropylene production through hydrocarbon cracking add further to the emissions tally.
  • Methanol production from syngas also significantly contributes to emissions.
  • The industry’s dependence on fossil fuels for the high temperatures needed in chemical reactions is a major hurdle.
  • The current infrastructure is heavily invested in and optimized for fossil fuel use.
  • Shifting to renewable energy sources presents both technical and economic challenges.
  • Chemical processes generate CO2 emissions not only from fuel combustion but also from the reactions involved in hydrogen production and other chemical syntheses.

Strong start need to be made during the 2020-2030 period that can provide some modest short-term successes but more importantly, build a robust platform for significant decarbonization post-2030.

What could be the roadmap for such a start? Analyses along the following dimensions could be useful to arrive at it.

  • Decarbonization avenues – A comprehensive list of low-carbon or zero-carbon alternatives available for the industry
  • Stakeholders – Key decarbonization stakeholders within and outside the industry
  • Strategic intent – Tactical and long-term low-carbon objectives

Key Decarbonization Avenues

  1. Energy & Resource Efficiency
    • Technology Integration: Incorporating digital tools and AI-powered applications to optimize processes.
    • Waste Heat Recovery: Converting low-grade waste heat into useful energy, reducing overall consumption.
  2. Green Hydrogen
    • Production Shift: Transitioning from fossil-based hydrogen to green hydrogen produced via water electrolysis powered by renewable energy.
  3. Renewable Heating
    • Bioenergy Utilization: Using renewable natural gas from biomass waste to replace fossil fuels in heating applications.
  4. Electrification of Heating
    • Renewable Energy: Electrifying heating processes using renewable energy sources like heat pumps and electric boilers.
  5. Recycling and Reuse
    • Advanced Recycling: Enhancing recycling processes to convert semi-processed raw materials and waste into valuable products.
  6. Low-Carbon Waste Feedstock
    • Waste Utilization: Using plastic waste and other low-carbon feedstocks for chemical production.
  7. Bio-Based Alternatives
    • Sustainable Materials: Increasing the use of bioplastics and bio-based chemicals to replace traditional petrochemical products.
  8. CO2 Capture & Utilization
    • Emission Reduction: Capturing CO2 emissions and converting them into useful chemicals and fuels.

Status & Current Potential

Hence, several decarbonization avenues exist for the chemical industry. But each carries its own benefits and constraints. It is thus important for the industry to have better clarity on the status and decarbonization potential that each of these avenues presents.

To enable this, for each avenue, a brief summary is provided on the current status and its likely impact on decarbonization for two periods: 2020-2030 and 2030-2050.
