Tortoise Decarbonization Infrastructure Index℠ (DCRBN)

The Tortoise Decarbonization Infrastructure Index℠ is a float-adjusted, capitalization weighted index of decarbonizing infrastructure companies that are organized and have their principal place of business in the United States or Canada.

Overview

Decarbonization is a global mega trend as the world strives to achieve climate goals. Decarbonization infrastructure facilitates emissions reduction as higher carbon emitting fuels like coal, gasoline and diesel are replaced with wind, solar and natural gas. The Tortoise Decarbonization Infrastructure Index is a float-adjusted, capitalization weighted index of decarbonizing infrastructure companies that are organized and have their principal place of business in the United States or Canada. We define a decarbonization infrastructure company as a company that primarily owns natural gas and/ or natural gas liquids infrastructure including pipelines and local distribution companies, electric generation, transmission and distribution, battery storage, electric charging infrastructure, residential rooftop solar facilities and/ or renewable fuels.
