The Low-Carbon Transition Index. The data, not the noise.
An annual independent index tracking real-economy progress on the low-carbon transition. Seven indicators. Primary sources only. Published each year to build a consistent, citable dataset.
One clear direction. Not enough speed.
There is a persistent gap between how the energy transition is perceived and what is actually happening. Political attacks, investor nervousness and news cycles have created the impression of a stalling, contested, uncertain shift. The data tells a different story.
Since the Paris Agreement in 2015, every major leading indicator of transition progress has moved in the right direction. The question is no longer whether the transition is happening. It is whether it is happening fast enough. And on that question, the answer is: not yet.
Perigon's LCTI scores seven indicators on direction of travel and performance relative to the pace required to align to the IEA's 2035 Stated Policies goals. We combine directional and relative performance scores for each indicator, weighted 60/40 in favour of relative performance.
Seven indicators. 2026 scorecard.
Electricity greening
Renewables 46% of installed global capacity
Transport electrification
EVs exceeded 20% of global car sales in 2024
Low-carbon fuels
Share increasing; hydrogen scaling slowly
Battery storage
23% growth but needs 10x by 2035
Industrial electrification
Below pace required for STEPS
Energy intensity of GDP
1.2% in 2024; needs 2.2% for STEPS
Deforestation
2024 rate was 63% above the required trajectory
First edition. The baseline is set.
All seven indicators across six sections, with a full Data Explorer, appendix and methodology. The first in an annual series.
Primary sources only. No sponsor influences.
Every data point in the LCTI comes from a named primary source: IEA, IRENA, BloombergNEF, SBTi, Oxford Climate Policy Monitor, TPI, WRI and others. The index is entirely independent. No institution has paid to be included. No sponsor influences the findings.
Primary sources only
IEA, IRENA, BloombergNEF, SBTi, Oxford Climate Policy Monitor, TPI, WRI and others. All cited in full.
Scored two ways
Each indicator scored on direction of travel (year-on-year) and performance relative to IEA STEPS 2035 goals. 60/40 weighting to relative performance.
Annual cadence
Published each year to build a consistent dataset. Same seven indicators tracked throughout for comparability.
No political position
The LCTI describes what the data shows. Perigon does not advocate for specific policies. We report on what is happening and what the gap is.
