During 2016 and 2017, the UN Environment Programme implemented a Programme of Work that represents the second half of the organization’s Medium-Term Strategy for the period 2014-2017. In doing so, we partnered with governments, the private sector, the scientific community, the UN system, and ordinary citizens across the planet. What we are presenting here is an account of the changed situation which exists as a result of all our work. In some instances, our work has made a direct impact on the outcome described. In many more instances, we were merely one of many contributors. The main point is that change has occurred and progress has been registered. We have taken care to record, in a detailed manner, the extent of the change, the degree to which we contributed, or the extent to which that change can be attributed to our work.
