TPI publishes consolidated report containing decarbonisation pathways for all high-emitting sectors

Transition Pathway Initiative’s sectoral decarbonisation pathways provide the definitive framework for assessing corporate climate targets in 10 key high emitting sectors within energy, transport and industrials.

  • TPI’s sectoral decarbonisation pathways, which are based on IEA scenarios, allow investors to assess the credibility of corporate net zero commitments. The pathways and the underlying methodologies are publicly available to all.
  • The Transition Pathway Initiative is backed by investors with over $40 trillion of assets under management or advisement. Its benchmark pathways are used by the Climate Action 100+ (CA100+) and by many of the world’s largest and most significant asset owners and asset managers.
  • “In order to allow investors to see whether a company’s emission reduction plans align with the goals of the Paris Agreement, TPI has translated IEA models into decarbonisation pathways for each sector. This report explains our methodology in an accessible way.” Professor Simon Dietz, Research Lead for TPI at LSE.


In a report published today, the Transition Pathway Initiative (TPI) published details of the sectoral decarbonisation pathways that many investors and the CA100+ initiative now use to judge whether companies are on track to transition to net zero between now and 2050. The report synthesises the methodologies developed by TPI over the past five years, including TPI’s recent work on 1.5 Degrees aligned sectoral pathways – which are new this year following the publication of the IEA net zero scenario.

The pathways are used by investors and investor networks to assess how far companies in their portfolios are aligned with the goals of the Paris Agreement. As an example, TPI’s decarbonisation pathway for aviation states that if an individual company wants to be aligned with a 1.5°C path then its emissions intensity by 2030 must be below 616 tonnes of CO2/RTK (revenue tonne kilometre).

This level of granular detail allows investor to judge companies’ target-setting, and to hold companies to account as their real-world emissions are reported year-on-year. In this way, the benchmarks help inform how investors can assess the Paris-alignment of their portfolios related to this key sectors.

Simon Dietz, Research Lead for TPI at the Grantham Research Institute on Climate Change and the Environment at LSE said:

“In order to allow investors to see whether a company’s emission reduction plans align with the goals of the Paris Agreement, TPI has translated IEA models into decarbonisation pathways for each sector. This report explains our methodology in an accessible way.

We hope this report catalyses the real economy transition plans that we urgently need to avoid the most catastrophic effects of global warming. It is now time to turn commitment into action.”

TPI’s sectoral decarbonisation pathways use primarily data from internationally recognised climate modelling, such as by the IEA. The pathways are a result of the application of the Sectoral Decarbonisation approach in rigorous methodologies created by researchers at the world-renowned Grantham Institute for Climate Change and the Environment at the London School of Economics (LSE).

Key features of the TPI sectoral decarbonisation pathways:

  1. Sector-specific methodologies are based on the Sectoral Decarbonisation Approach, allocating anabsolute, economy-wide emissions budget to each sector.
  2. Sectoral benchmarks arederived from IEA modelling – showing scenarios meeting 1.5 degrees, below 2 degrees, and aligned with National Pledges – for most sectors.
  3. TPI benchmarks cover themajority of lifecycle emissions in each sector.
  4. The benchmarksextend to 2050, allowing investors to see a company’s transition pathway in the short, medium, and long term.
  5. In nearly all sectors, company emissions arenormalised against a physical activity output – allowing comparison between companies.
  6. The benchmark methodologies can be adapted to new models and scenarios.
  7. The benchmarks and methodologies are available for everyone to use.


The sectors covered are within Energy (Electricity, Oil & Gas), Industrials (Aluminium, Cement, Diversified Mining, Paper, Steel), and Transport (Autos, Aviation, Shipping).

Adam Matthew, Chair, Transition Pathway Initiative, and Chief Responsible Investment Officer, Church of England Pensions Board said:

“TPI’s sectoral decarbonisation pathways meet the demand from all stakeholders – investors, companies, civil society organisations – for a credible, rigorous framework for assessing corporate climate change performance. They are recognised by investors as the authoritative translation of the IEA’s scenarios into credible performance benchmarks for industry sectors and for individual companies.

“In a world where we are faced with multiple interpretations of what the low carbon transition should look like (often with the intention of slowing rather than accelerating the rate of change, and often to argue for less ambitious action by companies), it is imperative that we as investors make decisions based on credible, rigorous analysis that is explicitly focused on the goal of net zero and that reflects the economic, technical and societal realities of the low carbon transition. The TPI sectoral decarbonisation strategies provide that analysis.”
