Business Sustainability Reporting

Update on November 27, 2025: We are pleased to announce the publication of our textbook 'Business Sustainability Reporting & Analysis' with Cambridge Business Publishers, available at: https://mybusinesscourse.com/book/bsra1e . Instructors are also able to request access to additional instructional materials from the publisher.

With the publication of our book, we are no longer providing teaching materials here. We hope that you have found the website useful in your business sustainability reporting teaching journey.

Notes:

1. Carbon dioxide data is sourced from the NOAA and measured at the Mauna Loa Observatory. Available at: https://gml.noaa.gov/webdata/ccgg/trends/co2/co2_mm_mlo.txt

2. Global warming data is obtained from NASA's Goddard Institute for Space Studies (GISS) and is available at:

https://data.giss.nasa.gov/gistemp/graphs_v4/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt

To measure global warming relative to the average for the 1850-1900 'pre-industrial' period, we follow the GISS guideline of adding 0.19ºC to the reported numbers that use a 1951-1980 base period. For details, see:

and refer to "Q. How can I estimate the anomaly with respect to the ‘pre-industrial’ (1850-1900) period?"
