CO2 Controlling in Businesses
Christoph Ernst, University of Mannheim
How can companies do carbon accounting and decarbonization management?
The presentation illustrates how internationally proven accounting tools and procedures can help companies to re-use their bookkeeping and controlling for carbon accounting. The corporate accounting system is extended to include carbon. This enables meaningful, comparable and verifiable reporting for all interested parties. Decarbonization can thus be implemented in a more strategically focused manner.
