Low-Carbon Transition Index. Est 2025.
An annual independent index that digs beneath the perception to track global real-economy progress on the low-carbon transition across fourteen indicators.
The reality versus the hype.
Newsflow, fund flows and politics have created a perception of the low-carbon transition (resembling Gartner's hype cycle) that is often at odds with reality. To cut through the noise, Perigon has compiled a Low-Carbon Transition Index (LCTI) to get a clearer view of real progress.
Although absolute emissions continue to rise at a global level, the underlying picture from leading indicators is one of steady positive momentum in the energy transition since the Paris Agreement. That said, a clear acceleration in progress is required to align with the IEA's Stated Policies Scenario (STEPS).
Perigon's LCTI highlights positive direction of travel across key energy-related and enabler indicators in 2024. However, non-energy-related indicators are behind in both measures of performance.
There will be a low-carbon transition. The extent to which, and by when, we reach net zero may vary significantly across sectors and regions. Strong growth in targets and investment would support an acceleration in the LCTI, though likely still short of the required rate.
Source: Perigon Partners analysis, January 2026. Perigon's ETI comprised of seven energy-related indicators including the greening of electricity generation and increasing battery storage capacity; as well as the electrification of transport, buildings and industry; the reduction in the energy intensity of GDP and the increasing share of low carbon fuels.
Examining annual performance of the broader low-carbon transition components shows a more nuanced picture with acceleration required.
Perigon's LCTI scores fourteen indicators on direction of travel and performance relative to the pace required to align to the IEA's 2035 Stated Policies goals and its Net Zero Scenario. For non-energy indicators, we track against equivalent pathways where available. We combine directional and relative performance scores for each indicator to produce our index scores.

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 what is required to align to the 2035 goals of the stated policies scenario (STEPS). 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.

We aim to provide a single, rich source of consolidated data and research to paint a clear and detailed picture of what is really happening with the global climate transition. Use this to inform your company's plans and provide context to the Board and ExCo.
Emissions are still rising globally. But the trajectory is shifting.
Global CO₂ emissions from fossil fuels reached nearly 40 billion tonnes in 2024 — yet the rate of growth has slowed by around 60% since 2010. The picture varies significantly by region, sector and income level, with high-income countries increasingly decoupling growth from emissions while China and Asia continue to drive global totals higher. The UK stands out as 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 continued to strengthen 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 IEA Stated Policies Scenario, most indicators need to accelerate meaningfully between now and 2035.
The hardest indicators to move. And the biggest gaps.
Non-energy indicators lag furthest behind the transition pathway. Dietary change, deforestation and carbon capture all face significant shortfalls against what either the IEA STEPS or Net Zero scenario requires. 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.
Progress is real and measurable. But reinvention must accelerate.
Corporate commitment to the low-carbon transition has grown substantially. 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.
14 indicators. Two pathways.
Each indicator scored 0–100 against IEA STEPS 2035 and Net Zero pathways. Scores combine direction of travel (40% weight) and pace relative to pathway requirements (60% weight). A score of 80+ is considered on track.
