Workbook for estimating operational GHG emissions – version 16

UKWIR has developed a standardised workbook for estimating operational greenhouse gas emissions, the Carbon Accounting Workbook (CAW), to bring consistency and accuracy to the reporting process across the water industry. The workbook has been in place for over ten years and is updated annually to reflect the needs of the industry, including changes in carbon accounting practices. 

This report sets out the changes that have been made in CAW 16. Some of these changes were implemented as a result of a review that was undertaken to assess the alignment of the CAW with the ISO14064 standards.
