We set out to analyse FTSE 100 companies’ emissions reduction targets. These fall into two camps: Scope 1&2 (emissions from a company’s operations), and Scope 3 (emissions resulting from their suppliers and consumers). This is the Scope 1&2 emissions reduction target for Unilever, a consumer goods company.
Emissions reductions can be linked to different climate heating scenarios, ranging from below 1.5C up to 3.2C. Temperature ratings map the ambition of companies’ targets to these pathways – Unilever’s Scope 1&2 target is aligned with global heating of 1.5C.
Using data from Tortoise’s Responsibility100 Index, Tortoise calculated pathways for all 100 FTSE companies – while some are aligned with the Paris Agreement, the majority have not set sufficiently ambitious targets.
Another aspect of the analysis reveals how fast companies have managed to cut emissions since they declared a reduction target – are they on track to meet their targets? Consider a company which has cut emissions by 15% since 2018, and has a target of 50% reduction by 2030.
Temperature ratings are a system for assessing the ambition of a company’s targets, producing a score from 1.5C to 3.2C which represents the level of global heating to which a company is aligned.
On average, FTSE 100 companies are on track for 2.8C of heating, well above the 1.5C aim set out in the Paris Climate Agreement. Read more about our findings in the Net Zero Sensemaker.
Temperature ratings, developed by CDP and WWF, are a framework for assessing companies’ emissions targets. To arrive at a score, the average reduction in emissions required to meet a company’s medium term (2020-2035) targets is calculated for Scope 1&2, and Scope 3 separately. These reductions are then combined as a weighted average to produce a final temperature rating.
To assess whether or not companies are on-track to meet emissions reduction targets, we extrapolated their average reduction since their baseline year to see if it puts them on track to meet their target. For this analysis we only considered Scope 1&2 emissions, since changes in Scope 3 emissions are often linked to improved reporting rather than true changes in emissions.
