Overview
As the transition to a lower-carbon economy accelerates, investors are adopting increasingly sophisticated approaches to integrate climate considerations into their strategies—addressing sustainability risks and opportunities across asset classes.
Key catalysts driving this trend and shaping sustainable infrastructure investment include rising capital requirements, the energy transition, net-zero digital and AI infrastructure, climate adaptation, and the circular economy.1
Incorporating climate transition and the green economy into listed infrastructure
The FTSE Sustainable Infrastructure Index Series is a next-generation complement to the FTSE Infrastructure Index Series, purposely built to align with the global shift toward sustainable infrastructure. Designed for investors seeking stable, inflation-linked returns while meeting credible sustainability objectives, it offers targeted exposure to listed infrastructure assets with attractive characteristics, including:2
− Liquidity and transparency in line with public equity markets
− Greater inflation sensitivity versus conventional equities
− Defensive qualities and resilience during market downturns
− Possible yield enhancement.
This index series also enables investors to manage the climate and sustainability risks and opportunities related to the infrastructure asset class —such as higher energy use and carbon intensity compared to other equity sectors.3

Investment opportunity and benefits
The FTSE Sustainable Infrastructure Index Series supports a dual investment thesis:
1. Green infrastructure for transition: building new low-carbon systems
− Global renewable power capacity is projected to double by 2030, increasing by 4600 GW—roughly the equivalent of adding the combined power generation capacity of China, the EU and Japan to the global energy mix
− Renewable energy consumption in transport—including liquid biofuels, biogases, and hydrogen-based fuels—is projected to rise 50% by 2030. Nearly half of this growth (45%) will come from renewable electricity powering electric vehicles, driven largely by China and Europe.1
2. Upgrading existing infrastructure for adaptation: enhancing resilience to physical climate risks
− 34% of companies in the FTSE All World Index—covering over 4,000 large- and mid-cap firms across developed and emerging markets—now disclose adaptation activities addressing physical climate risks in their corporate reporting.2
− Over 2,100 companies generated more than USD1 trillion in revenues from products and services supporting climate adaptation—representing about one-fifth of the global green economy in 2024. Green buildings lead the way, contributing USD424 billion and standing as the largest sector with adaptation exposure.2
