Chemicals and climate: How to align with the SBTi’s chemical sector guidance

The chemical sector is the world’s largest industrial consumer of energy products, driven by its reliance on fossil fuel feedstocks and the use of fuels for energy production. It is also the third largest industry subsector in terms of direct CO2 emissions, and its range of highly diversified products is crucial to many other industrial sectors.  

Given the chemical sector’s significance, the SBTi has developed sector-specific, emission-reduction pathways and criteria to support target setting for priority emission sources. These trajectories offer tailored options for chemical companies to set ambitious, credible targets. Adopting the new pathways as part of your target setting and decarbonisation efforts will help your company demonstrate leadership, accelerate innovation, and build a stronger, more resilient business. 

 

Who will be impacted?

The pathways and its criteria are relevant to any company that manufactures products within the scope of the below chemical types:

 

 

Key elements of the draft guidance

If you would like to adhere to the mandatory and optional pathways guidance within the SBTi Chemical Sector Pathways and Implementation Criteria, you will have to adjust some of your current emissions inventory practices, as well as your decarbonisation strategies.

Nitric acid

N2O emissions under Scope 1 (Mandatory):

The only mandatory pathway in the SBTi’s Chemicals sector guidance relates to N2O emissions from the production of nitric acid, which is primarily used in the manufacture of nitrogen fertilisers, as well as in other applications such as explosives and dyes. If N2O emissions (on a CO2e basis) are 5% or more of total Scope 1 emissions, companies must commit to reducing their emissions intensity in line with the benchmark of 0.5 kgN2O/tonne of nitric acid produced, by 2035 at the latest.

Once a company’s average emissions intensity for N2O emissions from nitric acid production has reached this benchmark, a separate emissions intensity target on these emissions is no longer required. This may occur before or during the target year.

Primary chemicals

Ammonia (Optional):

There are two pathways for ammonia production, depending on whether it is used solely for non-energy purposes, such as in fertilisers, or for non-energy and energy purposes. Companies can use either pathway, but not both.

Targets are set based on an emissions intensity per tonne of ammonia produced, starting at 2.61 kgCO2e/kg ammonia for non-energy purposes, and converging on zero by 2050. The pathway for both non-energy and energy purposes also starts at 2.61 kgCO2e/kg in 2020 and reduces to 0.04 kgCO2e/kg in 2050.

Ammonia producers will therefore need to significantly improve the efficiency of their production to reduce their emissions intensity. This could involve switching to green hydrogen produced via renewable-powered electrolysis or increasing the use of lower-carbon energy sources. 

Methanol production for non-energy purposes (Optional):

Methanol is a key chemical feedstock for formaldehyde production, acetic acid and other products, as well as a key combustion fuel and solvent. This pathway states the expected emissions intensity of methanol production, falling from 2.58 tCO2e/tonne in 2020 to 0.09 tCO2e/tonne in 2050. To meet the intensity target companies will need to reduce emissions through measures such as transitioning to renewable energy use, process optimisation and the use of alternative feedstocks, including biomass. 

High-value chemical (HVC) production (Optional):

Olefins, benzene, toluene, and aromatics are all considered HVCs in the SBTi guidance. This pathway outlines the expected emissions intensity reduction, starting at 1.06 kgCO2e/kg HVC and converging on 0.04 kgCO2e/kg HVC by 2050. Companies will need to reduce emissions through measures such as transitioning to renewable energy use and process optimisation.

Non-primary chemicals

Scope 1 emissions (Optional):  

Non-primary chemicals are any chemical other than primary chemicals or nitric acid that fall under the SBTi chemicals sectoral boundary. This pathway is based on an absolute emissions reduction percentage through to 2050, starting at 4.8% in 2030 and rising to 94.6% in 2050. To meet the SBTi target, companies should implement measures to reduce emissions, such using bio-feedstocks, process optimisation, transitioning to renewable energy use and reducing process-related greenhouse gas emissions like methane.

Nitrogen fertilisers

Nitrogen fertilisers (Optional):

Nitrogen fertilisers – such as urea, ammonium nitrate and more – emit N2O when applied to land. The SBTi has therefore provided an optional target pathway for companies that sell nitrogen fertilisers based on the reduction of N2O emissions from the use-phase of nitrogen fertilisers in the near and long term.

This is an important consideration for nitrogen fertiliser producers, who have limited direct control over downstream emissions from the use of their products. However, they can influence outcomes through measures such as developing improved fertiliser formulations, providing guidance on optimal application practices and supporting better land management through advisory services and partnerships.

Alternative feedstocks

Alternative feedstocks (Optional):

The optional pathway for the share of purchased alternative feedstocks is split out depending on whether mechanical recycling is included or excluded.

This pathway focuses on one of the key levers for decarbonisation of the chemicals sector: reducing the reliance on fossil-based feedstocks by progressively transitioning to alternative feedstocks and recycled materials. 

Exclusions

The scope of the pathways does not include:

  • Emissions from the production of final products that may be manufactured using the chemicals mentioned above if these activities do not involve the synthesis of new chemical products, such as plastic packaging or the blending of cosmetics, textiles, detergents, paints, or inks.
  • Emissions from mechanical recycling activities.
  • Emissions from the production of biofuels.
  • Emissions from the production of chemicals in refineries.

How to get started

The first step is to assess whether the guidance is relevant to your operations and, if so, which of the sector-specific pathways are applicable to your business. There is only one mandatory pathway: N2O emissions from nitric acid production. For manufacturers of other chemical products, it will be important to establish whether the optional pathways could support your business’ sustainability objectives or whether a cross-sector target-setting option would allow greater flexibility.  

In preparation for the chemicals sector guidance taking effect in June 2026, the immediate steps for your internal team are to:

  1. Assess if your footprint is of sufficient quality to set robust targets. If not, prioritising data quality improvement is key.
  2. Map the areas of your business that are impacted by the guidance and confirm whether these activities fall under the mandatory or optional pathways.
  3. Consider expected future changes in your business growth and emissions in the areas in scope of the guidance, including the reduction initiatives being prioritised based on their impact, cost and implementation readiness.  
  4. Evaluate the pros and cons of using the optional pathways or target setting and decide the best way forward based on your business strategy.
