Introduction

The Rail Carbon Accounting Framework (RCAF), developed in collaboration with the rail industry, Government, and the Science Based Target Initiative (SBTi), provides a consistent approach to calculating greenhouse gas (GHG) emissions across the rail sector. This framework aims to assist the rail sector in achieving its net-zero commitments by 2050.

Background and Need for the Framework

Prior to the RCAF, carbon reporting within the rail sector was inconsistent. The absence of a unified framework hindered the consistent benchmarking of rail performance and the calculation of total sector emissions. Consequently, the rail industry invested significant time and resources in developing separate accounting methods.

Key Features and Benefits of RCAF

RCAF addresses these issues by providing a unified framework. Graham Mollison, project sponsor and Head of Sustainability for Southeastern Rail, highlighted that RCAF is designed to align the rail industry’s carbon reporting. He noted that it previously was challenging for each company to determine the exact carbon data needed for impact reporting.

Impact on Carbon Accounting and Industry Goals

Mollison further stated that RCAF offers clarity and certainty in developing carbon accounting methodologies, supporting the industry’s progress towards net-zero carbon emissions. Noah Myers, RSSB’s Carbon Lead, emphasized the challenge the rail industry faces in affordably reducing emissions across its various activities and entities.

Strategic Planning and Operational Decision-Making

Myers added that the RCAF replaces fragmented calculation methodologies with a unified approach. This unified approach supports both strategic planning and operational decision-making. This will result in time and cost savings, improved data quality, and smarter investment in sustainability.

Conclusion

The RCAF aims to provide a standardized method for calculating and reporting GHG emissions in the rail sector, supporting net-zero goals by 2050. The framework offers clarity in carbon accounting, supports strategic planning, and aims to improve data quality and reduce costs.
