With the environment and global warming in its current predicament, it’s no surprise that environmental science job opportunities will be on the rise in the very near future.

With the environment and global warming in its current predicament, it’s no surprise that environmental science job opportunities will be on the rise in the very near future. Therefore, so are the numbers of students pursuing studies in this field. The last four decades have seen huge changes in the rate of global warming and so more than ever before, we need people to study topics in environmental science.

For anyone majoring in environmental science, anyone needing to write environmental studies project topics for a science course, or essay writer who is working on topical essays this comprehensive article will talk you through the top ten project topics to pursue. For each project topic, we’ll give you ten ideas.

Climate Change

There’ll always be an environment, but it’s looking more and more likely that it won’t be like our current one in the future. With this in mind, here are the top ten environmental project topics for college students on climate change:

  1. Is global warming a natural phenomenon?
  2. The politicization of global warming.
  3. How do eddy covariance towers work?
  4. Planetary tilt – does it affect global warming?
  5. The differences between climate change and the greenhouse effect.
  6. Why is carbon dioxide a greenhouse gas?
  7. How do changes to weather patterns affect the Earth’s climate?
  8. The concept of polar amplification.
  9. The barriers to climate change responses.

  7. How does using an ANN (artificial neural network) for rainfall-runoff affect ecosystems?
  8. How do land-use changes impact urban runoff?
  9. Relationships between water quality, land use and land use change.
  10. Land use effects on lake water quality.


Pollution is one of the planet and humanity’s worst enemies. Agriculture, transportation, and industry can cause horrific environmental catastrophes. Check out the possible environment science project topics on pollution:

  1. The impact of pollution on health care.
  2. The effects of environmental pollution and water pollution on marine life.
  3. The effects of air pollution on the food chain.
  4. How environmental pollution affects Arctic.
  5. The health hazards associated with waste accumulation and water pollution.
  6. How do human activities change the world’s oceans?
  7. Conservation and how it helps to reduce air pollution.
  8. The difficulty of establishing direct links between health problems, air pollution, and air quality.
  9. Environmental policy regarding air pollution and acid rain.
  10. The effect of acid rain in urban and natural areas.

Environmental Science Topics for College Students

Environmental studies at college is all about studying in-depth biological, chemical, and physical processes on Earth. Environmental sciences also incorporates social, cultural, and political processes that have an impact. When studying Environmental Science at college level, a project need to seek out ways to present complex relationships in a simple way. Here are some ideal environmental science projects for college students:

  1. Genetically Modified (GM) foods and their impact on the environment.
  2. The global impact of radiation and nuclear accidents.
  3. The role of the UNEP in environmental conservation.
  4. The impact of freak weather incidents.
  5. Micro-plastics in drinking water – why and how have they got there?
  6. The Nagasaki and Hiroshima bombings – what have we learned about nuclear bombs and the effects on the ecosystem?
  7. The impact of Coronavirus and maintaining the ecosystem.
  8. The role of the media in conservation campaigns.
  9. Tourism and the impact of human activities on a local and global level.
  10. How has the US departure from the Paris Climate Agreement changed things?

Energy Resources and Consumption

Lots of environmental studies project topics goes into looking at energy resources and consumption, which makes this a great project topic. There is already a lot of information out there, which makes this easy to research.

  1. What is the relationship between energy efficiency and energy conservation?
  2. What are the economic, social, and environmental costs of solar energy?
