Index Description

The STOXX CTB Indices are based on liquid securities from a selection of STOXX Benchmark Indices. They follow EU CTB (EU CTB) requirements outlined by the European Commission on climate benchmarks. Companies identified as non-compliant based on Norms-based Screening assessment, or involved in controversial weapons or tobacco, as identified by ISS ESG are not eligible for selection. Furthermore, STOXX will exclude companies that ISS ESG assesses to have significant obstruction in the following UN SDGs: SDG 12 Responsible Consumption and Production, SDG 13 Climate Action, SDG 14 Life Below Water and SDG 15 Life On Land. The weighing process reduces the indices' greenhouse gas intensity by at least 30% when compared to their underlying benchmarks. They are also designed to meet the year on year 7% decarbonization target. STOXX uses the Axioma optimizer to keep the ex-ante tracking error of the index less than or equal to 1.5% relative to the parent index.

Key facts

  • The indices are designed to help investors shift towards a low-carbon economy and align investments to the Paris Climate Agreement
  • Scope 1, Scope 2 and Scope 3 are used across all sectors from the first date of the index construction
  • The indices aim to reduce their greenhouse gases emission intensity by at least 30% when compared to their underlying benchmarks and follow a year on year 7% decarbonization target
  • Sectors key to the low-carbon transition, high climate impact sectors are not underweighted relative to the underlying benchmarks
  • The index maintains a maximum ex-ante tracking error of 1.5% relative to its parent, calculated using the Axioma optimizer.

Performance and annual returns

Methodology

The STOXX CTB Indices are built from liquid securities within selected STOXX Benchmark Indices and comply with the EU CTB (EU CTB) requirements set by the European Commission. Companies are excluded if identified by ISS ESG as non-compliant through Norms-Based Screening, or if they are involved in controversial weapons or tobacco production. Additionally, companies assessed to significantly obstruct environmental UN Sustainable Development Goals—SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), SDG 14 (Life Below Water), and SDG 15 (Life on Land)—are removed from consideration. The index weighting is determined through an optimization process that incorporates carbon risk ratings and corporate climate commitments, targeting at least a 30% reduction in Scope 1+2+3 GHG intensity compared to the benchmark and a minimum 7% annual decarbonization rate. STOXX uses the Axioma Fundamental Factor Medium Horizon Risk Model to ensure the index’s ex-ante tracking error remains below 1.5% relative to the parent index.
