About 50 countries have prepared interimand full Poverty Reduction Strategy Papers (PRSPs). In thiscontext, this paper examines Millennium Development Goal(MDG)7: Ensuring Environmental Sustainability, its targetsand indicators, and responds to three questions: To whatextent do PRSPs define and adopt targets and indicators thatalign with those of MDG7? To what extent do the availabledata allow tracking of progress with respect to MDG7? Whendata are available, what are the trends, and how can thedata be effectively utilized to examine the status andtrends of countries in relation to MDG7? The assessment ofinterim and full Poverty Reduction Strategy Papers (PRSPs)shows that: 1) Only 12 of the 28 full PRSPs present someinformation on the baselines and targets in line with theMDG7; and none of the 22 interim PRSPs present discussion onthe long-term perspective; 2) Within the PRSPs that presenttargets aligned with MDG7, attention is almost exclusivelyfocused on water and sanitation; 3) Available data can beused to document the status and trends of relevant MDG7 indicators.
