 In fact, **all** activities that we undertake as part of our research produce carbon emissions. While, in an ideal world, we would be able to reduce emissions from all our activities we have finite time and effort so need to prioritise based on which reduction strategies will have the largest impact. This means that the first step is to estimate the emissions from different activities we are involved in as part of our research, even if the estimate is very rough.
