Least Environmentally Friendly Countries in the World 

Several countries are seeing a rise in environmental sustainability; however, a few face significant challenges due to socio-economic, political, and other industrial reasons. In this article, we will explore the ten least environmentally friendly countries in 2025, alongside the possible reasons for their actions. 

• India 

Several factors pollute India's environment, such as rapid industrial development, population growth, and mass urbanization. There exists a contradictory concept of high population density encouraging resource depletion; this, along with rapid urbanization, leads to even more resource deficits as pollution and deforestation rise. India heavily relies on coal-fueled power and emissions which significantly rely on greenhouse gases, these factors in conjunction with untreated industrial chemical discharges alongside mass pollution of the Ganges and other rivers, along with waste created by poor trash disposal, pollutes the water and ends up threatening not just durable ecosystems but human health as well. 

• China 

Despite China being one of the leaders in the renewable energy sector, its industries continue to contribute significantly to environmental pollution. The manufacturing and production processes are highly energy-intensive and result in severe water and air pollution. Cities like Beijing suffer from the urban air pollution crisis and smog episodes, whereas unregulated industrial effluents pollute water sources. Also, the extensive construction activities in China cause deforestation and destruction of habitats, even though there are efforts to plant trees. 

• Brazil 

The environmental concerns within Brazil are directly related to the deforestation of the Amazon rainforest, referred to as the "lungs of the Earth." Substantial areas have already cleared the Amazon because of logging, agriculture expansion, and cattle raising, which has resulted in a setback in the global efforts for carbon sequestration while threatening the region's biodiversity. Additionally, these logging and mining activities contribute to the destruction, going against Brazil's obligations on the global front about the environment. 

• Indonesia 

Indonesia has almost lost its rainforest by more than a quarter over 25 years, which is often blamed on palm oil production, which constitutes a crucial industry for the country. To add fuel to the fire, illegal logging and slash-and-burn land-clearing practices also worsen the country’s already alarming greenhouse gas emissions and contribute to the extinction of species like orangutans. Moreover, the country's marine life is on the verge of extinction because of pollution caused by plastic debris, overfishing, and other developments. 

• United States of America 

Being one of the top economically advanced nations, it is disappointing to see the United States performing poorly in terms of climate change issues because of pollution from its transportation industry and getting a host of climate change policies resisted politically. The energy and transportation of fossil fuels that the country consumes only aggravate carbon emissions. Further development, including sprawl and industrialized farming practices, promotes habitat destruction, leading to water pollution in areas like the Mississippi River Basin.

• Russia 

Russia faces various environmental issues due to its sheer reliance on fossil fuel products and a lack of investment in green energy. They hold the title of one of the world's biggest oil and gas producers, and their economy can be explained mainly by crude fuel-based industries. Environmental laws are in place, but they are usually poorly put into action, resulting in pollution via industrial activity to the air and bodies of water. Moreover, there is a large scale of mining activity happening, which puts more strain on the environment and makes it impossible to reverse the damage done. 

• Nigeria

Nigeria’s reliance on oil extraction has resulted in considerable-scale devastation and destruction of their environment. Areas in the Niger Delta that house oil reserves have been subjected to numerous oil spills that have contaminated the existing lands and water bodies, thus negatively affecting the local communities and marine life. Oil is also illegally refined, and gas is burnt, leading to air and greenhouse gas emissions. On top of everything, the country still has to deal with cut down of trees for agricultural and firewood purposes, as well as poor waste management systems. All of these factors further worsen the current environmental problems they face. 

• South Africa 

Out of all the African countries, South Africa emits the second highest amount of carbon due to their heavy reliance on coal-based energy. Mining for coal and opening coal plants cause severe environmental damage through air pollution and toxic runoff reaching bodies of water. South Africa also struggles with managing waste, as cities are not well equipped to deal with how much is generated, while recycling systems are heavily lacking. 

• Saudi Arabia 

Saudi Arabia is viewed as the largest oil exporter in the world, and this heavily affects its socioeconomic goals, particularly the goal of shifting toward renewable energy resources. Their dependence on oil discourages the practice of developing sources of energy, such as solar or wind power. Moreover, the need to desalinate water pushes the energy consumption even further. High urbanization rates lead to an increase in the use of air conditioners, resulting in higher energy consumption and greenhouse gas emissions. Some environmentally friendly programs have been started, but their pace has been dreadful. 

• Pakistan 

Large-scale deforestation, pollution of bodies of water, poor waste management, and the list of issues Pakistan faces regarding the environment goes on. Harsh runoff from agriculture and industries leads to water contamination, while high deforestation rates worsen the situation by causing soil erosion. 

How to Measure a Country’s Environmental Friendliness? 

Environmental Performance Index (EPI)

This metric has been calculated for each country by Yale and Columbia universities based on indicators relating to the following issues: 

• Air emission quality 
• Conservation of biodiversity and ecological systems 
• Sustainable agriculture 
• Climate change mitigation 

Carbon Footprint Metrics

This is the per capita amount of greenhouse gases a country produces. Countries that produce less carbon exhibit a higher commitment towards environmentally friendly initiatives. 

Renewable Energy Adoption

Monitoring the amount of energy obtained from wind, solar, water, and geothermal sources is an indicator of the level of commitment of a country toward investing in green energy technology. 

Waste Recycling and Water Usage Management

Water reuse and waste recycling rates alongside landfill diversion are also some of the parameters that gauge environmental friendliness. 

Participation and Support for International Treaties

Commitment towards sustainability is also reflected by countries doing their utmost to be part of international treaties such as the Paris Climate Agreement or the Sustainable Development Goals (SDGs).
