| Country | Environment - current issues |
| Peru | deforestation (some the result of illegal logging); overgrazing of the slopes of the costa and sierra leading to soil erosion; desertification; air pollution in Lima; pollution of rivers and coastal waters from municipal and mining wastes |
| Philippines | uncontrolled deforestation especially in watershed areas; soil erosion; air and water pollution in major urban centers; coral reef degradation; increasing pollution of coastal mangrove swamps that are important fish breeding grounds |
| Pitcairn Islands | deforestation (only a small portion of the original forest remains because of burning and clearing for settlement) |
| Poland | situation has improved since 1989 due to decline in heavy industry and increased environmental concern by post-Communist governments; air pollution nonetheless remains serious because of sulfur dioxide emissions from coal-fired power plants, and the resulting acid rain has caused forest damage; water pollution from industrial and municipal sources is also a problem, as is disposal of hazardous wastes; pollution levels should continue to decrease as industrial establishments bring their facilities up to EU code, but at substantial cost to business and the government |
| Portugal | soil erosion; air pollution caused by industrial and vehicle emissions; water pollution, especially in coastal areas |
| Puerto Rico | erosion; occasional drought causing water shortages |
| Qatar | limited natural fresh water resources are increasing dependence on large-scale desalination facilities |
| Reunion | void |
| Romania | soil erosion and degradation; water pollution; air pollution in south from industrial effluents; contamination of Danube delta wetlands |
| Russia | air pollution from heavy industry, emissions of coal-fired electric plants, and transportation in major cities; industrial, municipal, and agricultural pollution of inland waterways and seacoasts; deforestation; soil erosion; soil contamination from improper application of agricultural chemicals; scattered areas of sometimes intense radioactive contamination; groundwater contamination from toxic waste; urban solid waste management; abandoned stocks of obsolete pesticides |
| Rwanda | deforestation results from uncontrolled cutting of trees for fuel; overgrazing; soil exhaustion; soil erosion; widespread poaching |
| Saint Barthelemy | with no natural rivers or streams, fresh water is in short supply, especially in summer, and provided by desalinization of sea water, collection of rain water, or imported via water tanker |
| Saint Helena | NA |
| Saint Kitts and Nevis | NA |
| Saint Lucia | deforestation; soil erosion, particularly in the northern region |
| Saint Martin | fresh water supply is dependent on desalinization of sea water |
| Saint Pierre and Miquelon | recent test drilling for oil in waters around Saint Pierre and Miquelon may bring future development that would impact the environment |
| Saint Vincent and the Grenadines | pollution of coastal waters and shorelines from discharges by pleasure yachts and other effluents; in some areas, pollution is severe enough to make swimming prohibitive |
| Samoa | soil erosion, deforestation, invasive species, overfishing |
| San Marino | NA |
| Sao Tome and Principe | deforestation; soil erosion and exhaustion |
| Saudi Arabia | desertification; depletion of underground water resources; the lack of perennial rivers or permanent water bodies has prompted the development of extensive seawater desalination facilities; coastal pollution from oil spills |
| Senegal | wildlife populations threatened by poaching; deforestation; overgrazing; soil erosion; desertification; overfishing |
| Serbia | air pollution around Belgrade and other industrial cities; water pollution from industrial wastes dumped into the Sava which flows into the Danube |
| Serbia and Montenegro | void |
| Seychelles | water supply depends on catchments to collect rainwater |
| Sierra Leone | rapid population growth pressuring the environment; overharvesting of timber, expansion of cattle grazing, and slash-and-burn agriculture have resulted in deforestation and soil exhaustion; civil war depleted natural resources; overfishing |
| Singapore | industrial pollution; limited natural fresh water resources; limited land availability presents waste disposal problems; seasonal smoke/haze resulting from forest fires in Indonesia |
| Slovakia | air pollution from metallurgical plants presents human health risks; acid rain damaging forests |
| Slovenia | Sava River polluted with domestic and industrial waste; pollution of coastal waters with heavy metals and toxic chemicals; forest damage near Koper from air pollution (originating at metallurgical and chemical plants) and resulting acid rain |
| Solomon Islands | deforestation; soil erosion; many of the surrounding coral reefs are dead or dying |
