IFRS S2 CLIMATE-RELATED DISCLOSURES–JUNE 2023

Introduction

This volume is part of the Industry-based Guidance on Implementing IFRS S2 Climate-related

Disclosures. This guidance suggests possible ways to apply some of the disclosure requirements in

IFRS S2 but does not create additional requirements.

This volume suggests possible ways to identify, measure and disclose information about

climate-related risks and opportunities that are associated with particular business

models, economic activities and other common features that characterise participation in

this industry.

This industry-based guidance has been derived from Sustainability Accounting Standards

Board (SASB) Standards, which are maintained by the International Sustainability

Standards Board (ISSB). The metric codes used in SASB Standards have been included for

ease of reference. For additional context regarding the industry-based guidance contained

in this volume, including structure and terminology, application and illustrative

examples, refer to Section III of the Accompanying Guidance to IFRS S2.

Volume 45—Wind Technology & Project Developers

Industry Description

Wind Technology & Project Developers manufacture wind turbines, blades, towers and

other components of wind power systems. Entities that develop, build and manage wind

energy projects also are included within this industry scope. Manufacturers also may

offer post-sale maintenance and support services. Turbines may be installed onshore or

offshore, which can create differences in wind-generating capacity and project

development challenges for each type of installation. Most major wind technology

entities operate globally.

Materials Efficiency

Topic Summary

The Wind Technology & Project Developers industry’s long-term success depends on

producing energy at a comparatively lower cost than other energy sources. Steel and

other materials purchases are one of the largest costs of turbines, and inputs such as

steel have exhibited price volatility in the past. In recent years, wind turbines have grown

in size, in terms of both the tower height and the swept area of the rotor, to improve

energy output and increase the potential for wind energy production in more areas. To

achieve this expansion cost-effectively, entities may employ innovative methods to

increase turbine output while using materials more efficiently. Increased output and

efficiency could influence entities’ competitiveness and market share, costs of

production, and operational risks related to the supply and price volatility of raw

materials, as well as the ability of the entity to scale.

Metrics

RR-WT-440b.1 Top five materials consumed, by weight

For each of the following wind turbine classes, the entity shall disclose the

weight, in metric tons, of the five materials consumed in the greatest amounts, by

weight, in delivered wind turbines during the reporting period.

The scope of disclosure includes materials weights in the final delivered turbine,

including the nacelle, blades and tower, and excludes the weight of materials

consumed in production (for example, waste), freight, storage and installation (for

example, foundation).

Materials may include aluminium, carbon fibre, copper, fibreglass, iron or steel.

The entity may disclose the weight of the five materials consumed in the greatest

amounts by wind turbine class.
