Low-Carbon Transition Index. Est 2025.
An annual independent index of global real-economy progress on the low-carbon transition. Fourteen indicators, each scored against the pace required under stated policies and under net zero.
The direction is settled. The timetable is not.
Two things about transition investment are both true. It reached nearly $2.1 trillion in 2024, and its growth rate halved, from a 22% average since 2020 down to 11%. Which of those two facts is the more useful depends on the pace the transition actually requires, and that is what the Low-Carbon Transition Index measures. For each of fourteen real-economy indicators, is the current rate of change fast enough to arrive on time?
For 2024 the answer is that direction is largely settled and pace is not. Ten of the fourteen indicators improved on the previous year. Four of those improved fast enough to keep up with what current policy settings imply, and three fast enough for net zero by 2050. Absolute emissions are still rising, while the leading indicators have moved the right way in every year since the Paris Agreement.
The shortfall sits in particular places rather than across the whole index. Six of the seven energy-related indicators are improving, and so are all three enablers. Three of the four non-energy indicators score 33 out of 100 against both pathways. Where a falling technology cost curve does the work, the direction is positive and the argument is about speed. Where the answer depends on land, diet or a price on carbon, progress is slower and less consistent.
Ten of the fourteen indicators improved. Four are moving fast enough for stated policies, three for net zero.
Perigon's LCTI scores fourteen indicators on direction of travel, and on performance relative to the pace required to align with two pathways: Stated Policies, reflecting where current and planned policy leads, and Net Zero, reflecting what 1.5°C alignment would demand. The two scores combine to produce each indicator's score out of 100. The indicators are not all benchmarked against the same source, so the benchmark for each one is footnoted directly beneath the table.

Perigon's LCTI assigns each metric a score for its performance vs. the prior year (direction of travel) and a score for that performance relative to the pace required to reach the 2035 benchmark, under each of the two pathways. The two scores are then combined for each metric, with a higher weighting (60%) applied to relative performance, before being aggregated into the overall real-economy and enabler scores out of 100.

Benchmark year is 2035 for every indicator except deforestation, dietary change and reforestation, which are measured against 2030 targets.
Commitments, deforestation, dietary change and reforestation score identically against Stated Policies and Net Zero. Both scenarios come from the IEA World Energy Outlook, which does not cover these four, so no scenario-specific requirement exists to separate them. The single benchmark above is applied to both pathways.

Emissions are still rising globally. But the trajectory is shifting.
Global CO₂ emissions from burning fossil fuels reached nearly 40 billion tonnes in 2024, though the rate of growth has slowed by around 60% since 2010. The picture varies sharply by region, sector and income level. High-income countries are increasingly decoupling growth from emissions, while China and the rest of Asia continue to push global totals higher. The UK is one of the clearest examples that deep decarbonisation and economic growth can happen at the same time.
Policy, capital and commitments all moving forward.
Despite unprecedented political headwinds, the structural enablers of the low-carbon transition kept strengthening through 2025. All 37 jurisdictions tracked by the Oxford Climate Policy Monitor increased policy ambition. Corporate science-based targets now cover over 40% of global market capitalisation, clean energy investment reached $2.1 trillion, and under every NGFS scenario, the carbon price is set to exceed $100 per tonne by 2030.
Every major energy indicator is moving in the right direction. The question is how fast.
Renewables now account for over 90% of new power capacity globally. Electric vehicle sales have exceeded 17 million. Battery storage is scaling rapidly. Energy intensity is falling. The direction of travel is clear and consistent. What remains uncertain is whether the current pace is sufficient: under even the less demanding Stated Policies pathway, most energy indicators need to accelerate meaningfully between now and 2035.
Non-energy indicators are the hardest to move. Three of the four score 33.
Non-energy indicators lag furthest behind the transition pathway. Dietary change, reforestation and carbon capture all face significant shortfalls against what either pathway requires, each scoring 33 out of 100 on both. Their benchmarks come from three different sources, footnoted in the table above. Unlike energy indicators, where the direction of travel is broadly positive, progress here is slow, inconsistent, and in some cases barely measurable since the baseline was set.
Business progress is real and measurable. Scope 3 disclosure went from 36% to 49%.
Corporate commitment to the low-carbon transition has grown substantially. Transition Pathway Initiative (TPI) management quality scores are improving year on year, C-suite leaders are increasing sustainability investment, and decarbonisation has moved firmly into the realm of business strategy. The direction of travel is positive across all three measures, though the pace at company level must accelerate significantly to close the gap to net zero pathways.
Perigon’s Low-Carbon Transition Index. 14 indicators, 2 pathways.
Across all 14 indicators, the transition scores 65.2 out of 100 against the pace required under the Stated Policies pathway, and 58.1 against the pace required for Net Zero, as of December 2025. Each indicator score combines direction of travel (40% weight) and pace relative to the scenario requirement (60% weight). A score above 75 is considered on track.

Benchmark year is 2035 for every indicator except deforestation, dietary change and reforestation, which are measured against 2030 targets.
Commitments, deforestation, dietary change and reforestation score identically against Stated Policies and Net Zero. Both scenarios come from the IEA World Energy Outlook, which does not cover these four, so no scenario-specific requirement exists to separate them. The single benchmark above is applied to both pathways.
How the index is built.
Perigon's Low-Carbon Transition Index is an independent, annual assessment of real-economy progress toward the low-carbon transition, built entirely from named primary sources.
Two assessments per indicator
Each indicator receives two assessments for the year under review, both on a three-point scale. The first is its direction of travel: whether the metric moved favourably against the prior year. The second is its pace relative to the requirement: whether that movement was fast enough to align with the pathway in question.
The two combine into a single score out of 100, weighted so that pace counts for more than direction. Moving the right way too slowly is not alignment:
score = ( 0.4 × direction + 0.6 × pace ) ÷ 3, out of 100
Because both inputs are three-point scales, a score can only take one of six values: 33.3, 53.3, 60, 73.3, 80 or 100. Five of the six occur in this edition. 53.3, a negative direction with pace one band below the requirement, does not. This is a property of the method, not a limitation of the data. It also means any figure outside that set is not an output of this index.
Scores aggregate by unweighted mean, first within category and then across all fourteen. No indicator carries more weight than another.
The two pathways
Every indicator is measured twice: once against a Stated Policies requirement, reflecting where current and planned policy leads, and once against a Net Zero requirement, reflecting what 1.5°C alignment would demand. The pair gives a plausible-versus-required bracket rather than a single forecast.
For eight of the fourteen indicators these correspond to the IEA's Stated Policies and Net Zero Emissions by 2050 Scenarios. For the remainder, the equivalent ambition level is set by the most credible published reference available, and in one case by no published reference at all. Every indicator's benchmark is footnoted individually in the table above, and the six distinct sources are listed there in full.
Where a benchmark is identical under both pathways, an indicator scores the same on each. That is currently the case for four of the fourteen.
Score bands
Above 75 on track. Direction is positive, and pace is either at the required rate (100) or one band below it (80).
50 to 75 below required pace. Right direction, not fast enough.
Below 50 off track. Not moving, or moving the wrong way.
Every indicator has independently sourced observed data and a published benchmark. What differs is how strong that benchmark is, and we would rather set this out than smooth over it. In descending order: eight energy indicators are held against a fully modelled IEA scenario; carbon pricing against a published scenario set from the NGFS; commitments against a standard-setter’s dated requirement; deforestation and reforestation against a political pledge, which is an endpoint rather than a modelled trajectory; and dietary change against a national recommendation rescaled to a global baseline.
Dietary change is the weakest of these, and the reason is worth stating plainly rather than leaving a reader to find it. The UK Climate Change Committee’s 2022 recommendation of a 20% reduction in meat consumption by 2030 was calibrated to UK diets and UK policy. We apply that same 20% to the 2022 global average of 64.2 kg per person, which gives a 2030 reference point of 51.4 kg. A single proportional cut asks the same of every population, when consumption ranges from a few kilograms a head to well over a hundred. No global pathway for dietary change has been published, so there is nothing better available to measure against.
We keep the indicator because the underlying series is measured consistently and published openly, and because the emissions difference between meat types is well established. The gap is in the target, and in the methodology for setting one, rather than in the measurement. We will replace the reference point when a global pathway exists. Dropping the indicator instead would imply the question does not matter, when on the emissions arithmetic it is among the most material in the index.
A second limitation is worth naming. Both pathways are drawn from the IEA World Energy Outlook, which does not cover commitments, deforestation, dietary change or reforestation. Those four are measured against a single benchmark applied to both pathways, so they return the same score under each. The index does not imply that Stated Policies and Net Zero demand the same thing of them, only that no published scenario currently distinguishes the two.
