Concerns have been growing widely about changing environment and its impact upon the lives of the earth. In fact, areas of most researchers and efforts of most scientists are being concentrated towards environment in one way or the other. Accordingly, priority of the Government of Nepal has also been focused towards environment, be that in the name of “the Climate Change" or "Conservation" or " the quality of life of the people" and committed to combating climate change and achieving sustainable development goals (SDGs). Therefore, Central Bureau of Statistics (CBS), in the context of the increasing demand for environment related data, has been attempting to bring out special publication since decades and the present edition "Environment Statistics of Nepal 2019" is the 9th in the series.
