A significant proportion of the world’s businesses are small and mediumsized enterprises (SMEs). Globally, micro-enterprises (SMEs with fewer than ten employees) alone account for 70% to 90% of all firms1. As such, SMEs play an important role in reducing global emissions and bringing innovative climate solutions to the market. It is crucial that they are equipped with the tools and resources needed to measure their emissions, set greenhouse gas reduction targets grounded in science, take bold actions, report on their progress and ultimately reduce their emissions. This framework provides guidelines for SMEs on doing exactly that. It is open for anyone to use and can be used directly by SMEs to guide their reporting of climate impacts and strategies to multiple stakeholders. It can also be used by SME support organizations (such as consultancies) and data collectors to guide SMEs in climate disclosure.
