 As the poor are disproportionately affected by environmental degradation and lack of access to clean, affordable water, sanitation and energy services, UNDP seeks to address environmental issues in order to improve developing countries’ abilities to develop sustainably, increase human development and reduce poverty.UNDP works with countries to strengthen their capacity to address global environmental issues by providing innovative policy advice and linking partners through environmentally sensitive development projects that help poor people build sustainable livelihoods.UNDP's environmental strategy focuses on effective water governance including access to water supply and sanitation, access to sustainable energy services, Sustainable land management to combat desertification and land degradation, conservation and sustainable use of biodiversity, and policies to control emissions of harmful pollutants and ozone-depleting substances.
