Non-fossil carbon cycle TA R G ETS by-products, income from waste and income from subsidies. Only capital expenditure intended exclusively for environmental purposes is recognised as environmental investment. A proposal is currently being prepared for implementing these definitions within our financial systems. After approval, it will take some time to make the necessary changes to the systems at our breweries. 4.6 Carbon dioxide emissions The rising concentration of carbon dioxide in the atmosphere is one of the causes of the greenhouse effect and is held to be largely responsible for the climatic changes we have witnessed in the past fifty years, according to the Intergovernmental Panel on Climate Change. Heineken is including information on carbon dioxide emissions for the first time in this report. CARBON DIOXIDE EMISSIONS Carbon dioxide is emitted at vari ous stages in the beer production process. Malt sugars are converted into alcohol and CO2 during fer mentation, for example, but this does not contribute to the green house effect because it is a short- cycle process: the CO2 generated during fermentation is extracted from the atmosphere at a similar rate by the barley as it grows. This is in contrast to burning fossil fuel, which releases over a short period CO2 which has been locked up in the fuel for millions of years. Carbon dioxide is released when fossil fuels are burned. Heineken uses fossil fuels mainly for heating and, in some of our breweries, for electricity generation. Internal transport accounts for a small proportion of our fuel consumption. The reported figures do not include emissions due to activities outside Heineken locations, for example in external transport, nor emissions of short-cycle carbon dioxide (see panel above).
