10 Best Environmental Science Research Topics For 2022

Are you having trouble choosing a topic for your environment project? Breathe easy, as we have got you. In the article below we will walk you through the 10 best environment project topics that will guarantee you good grades. Let’s get rolling.

What is Environmental Science? If there were no humans, there would be no physics, economics, medicine, engineering, or education. The significance of the environment cannot be overstated. The environment is changing at a faster rate today than in any previous period since humans first came on the planet. As a result, finding people to investigate the environment and design measures to keep it safe is difficult.

Whether you’re majoring in environmental science or just want to write a great research paper, here are some of the most fascinating environmental science issues you may want to explore.

10 Best Environmental Science Research Topics For 2022

Let’s get started!

1. Climatic Change

One thing is for sure: the environment will always exist. But will it be livable? While everyone is affected by climate change, environmental scientists are the ones concerned about the detrimental effects of these changes. Thus, this is one of the hottest EVS project topics.

Climate change researchers are frequently up against a wall. You may be working on a single aspect of an issue. Alternatively, you may be charged with a more onerous duty, like convincing the local population to explain how climate change is real.

In any case, there are several opportunities in this sector. That’s especially true now that many countries have even chosen a science-focused approach, which means there might be more climate-related employment at government agencies shortly. 

2. Wildfires

While rising temperatures are causing more wildfires, many governments have taken on the burden of putting out all fires, no matter where they occur, for decades. We’re suddenly confronted with double standards and hypocrisy because this isn’t the normal course of events. We added more dry fuel to burn and increased the temperature at which it was done.

As a result, fire ecology is currently one of the most popular environmental project themes. Fire ecologists devote a significant amount of effort to researching how fires burn naturally, how they burn now, and how they might burn in the future. More importantly, these scientists are striving to understand how people may live in harmony with fire.

3. Save Energy or choose Renewable Energy Sources in the best way possible

We created a modern society and chose modernization, but we utilized fossil fuels. But now the misuse is bringing it all back to haunt us. One of the most effective methods to deal with this is to create renewable energy technologies like solar, wind, and hydropower. However, just because these new resources are carbon-free doesn’t imply that they’re free and harmless.

Wind energy, for example, which is frequently hailed as the ideal green energy source, has a terrible habit of knocking birds, especially endangered species, out of the sky. Fisheries suffer when migratory species, such as salmon, are unable to breed due to hydropower. Solar electricity may also prevent plants from receiving sunlight.

So, if you love to conserve mother Earth, creating a sustainable future necessitates recognizing possible dangers and determining ways to mitigate or remove them. This dependency will cost a lot later. So, before embarking on an environmental project, make an informed decision.


Greywater is sewage from sources other than toilets in the home. Greywater accounts for around 60% of all wastewater generated in homes. Water from showers and baths is recycled in a greywater recycling system. One may also collect water from the bathroom and wastewater from the utility sink and the washing machine. Blackwater refers to wastewater that contains toilet waste. It should never be recycled in the home since it includes human feces.

Recycling greywater has several benefits. It comes in handy when droughts or water shortages strike. Also, it is a great tool to bring down water bills. This way, water isn’t wasted at all. Even when there isn’t a water shortage, it can be utilized to conserve plants and vegetables.

Make a greywater recycling system for yourself. The most basic and affordable greywater recycling method is to collect shower and bathwater in a bucket and use it to flush the toilet. However, never fill the flush storage tank with greywater since this will cause it to swell and clog the flushing mechanism. A bucket can be used to collect greywater from a washing machine and to water your garden.

More costly systems are also readily available. However, you can build a recycling system at home or develop a tiny model to present at a science fair or any environmental exhibition with a few essential tools. It could be one of the award-winning environmental project topics.


5. Preservation with Urbanization

We tend to see the environment as a beautiful, remote location, similar to what you may see in a bottled water advertisement. However, the fact is that the environment is right where you are, even if it’s in the heart of a busy, polluted metropolis.

To live in harmony with the environment as the globe urbanizes, we must research and comprehend the effects of these changes. For example, how much property should be set aside as green space near subdivision streams? How can we avoid road pollution dumping on young fish after the next major rainstorm? Urban ecologists should keep taking this as an idea and try to solve these issues.

Some may argue that learning about these various effects and creating your chart takes more time and effort, but the benefits far outweigh the time and effort. That’s why it’s one of the best environmental project topics.

6. Geospatial Information Systems and Remote Sensing

Because of your physical limitations, you won’t be able to visit all of the areas you want to study. Even if you were able to, the environment would have altered by the time you arrived.

What is GIS? Scientists are increasingly using satellites and drones to observe the natural world and cover large land areas from afar. They can then use a geographic information system (GIS) application to visualize and evaluate the data they’ve gathered. GIS is used by scientists for many different purposes, including monitoring the environment’s greening as the rainy season approaches.

Currently, a lot of effort is being put into “ground-truthing” the data—that is, physically traveling to the locations where the satellites and drones are looking to check if the scientists’ estimations are appropriate. But no matter what, the skills in geographic information systems (GIS) are necessary and valuable in various disciplines, including city planning and engineering, thus leading to an interconnected system study for overall development. That adds value to any environmental science projects for college students.

7. Bioremediation

Pollution and contamination have emerged as side effects of our fast industrialization over the last several centuries. A lot of economic activity is bad for the environment because it releases heavy metals and even radioactive elements into people’s drinking water.

Cleaning everything up is a necessary task. What if, instead of shoveling dirt, you could spread microorganisms on the ground that ate and neutralized pollution? Bioremediation experts engineer microbes to clean up humanity’s worst calamities.

Sure, you undoubtedly learned about bioremediation in high school science class. But how does this connect to the real world? Yes. Bioremediation is broken down into a variety of specialties, each with its own set of methodologies and needs.

  • ‌Cleaning up a crime scene:

In this context, bioremediation refers to cleaning blood and body fluids that may include pathogens, such as hepatitis, HIV, and more. Instead of utilizing traditional cleaning chemicals, they employ enzyme cleaners to do away with hazardous compounds. The easiest way to learn more about this is to join forces with a business that specializes in this area of bioremediation and has nearly a decade of expertise in the industry. It would add nuance to your EVS project and help you choose environmental project topics wisely.

  • ‌Contaminated soil remediation:

Many hazardous chemicals have been introduced into the soil and groundwater due to human activities. “During bioremediation, microbes use the chemical pollutants in soil as a source. So, through oxidation-reduction processes, one can convert the target contaminant into useful energy for microbes. ” Thus, choosing a proper method for cleaning up the soil is the best way to check bioremediation.

  • Developing ideas for cleanup of an oil spill:

You may recall the Deepwater Horizon oil disaster, which resulted in the spill of 3.19 million barrels of oil off the coast of the Gulf of Mexico in 2010. Due to bioremediation’s efficacy and lower cost, two approaches were employed for clean-up. Thus, choosing the same to clean up with the following idea will be critical in saving our environment.

Bioaugmentation: A tiny amount of oil-degrading microorganisms is injected into a contaminated region.

Biostimulation: Nutrients are added to boost the growth of naturally occurring oil-degrading microorganisms, speeding up the cleanup process.

8. Noise Pollution

Noise pollution is a hazard across many industrial facilities and other workplaces. There is still congestion due to highways, trains, and airlines, as well as outdoor construction.

You might not think of noise as a pollutant (unless you’re trying to study for a project or problem), but it is. Researchers in this new discipline try to figure out how loud surroundings affect the creatures that live there.

How does the noise of airports, for example, influence neighboring wildlife? Or, how are the other animals influenced in the area? What happens if orcas that are threatened cannot echolocate due to the noises made by freighters transporting international cargo? How can city noises impact those who are attempting to sleep subtly? All of these are essential environmental project topics that noise pollution researchers are undertaking as an idea to try to address.

9. Limnology

Oceanographers are scientists who study the ocean, yet freshwater is frequently overlooked. Limnologists study freshwater, and their work is becoming increasingly important as we try to understand and restrict our impact on aquatic ecosystems.

Freshwater bodies of water have a higher risk of going wrong than oceans because they are much smaller. Dumping a wagon full of fertilizer into the water, for example, will have no effect. If you do the same thing in a lake, though, you risk eutrophication, which occurs when algae grow too quickly and suffocate all other aquatic life.

10. Conservation Biology

Between 200 and 2,000 species are expected to go extinct each year. Despite the fact that extinction is a natural process, humans have hastened it to disturbingly high rates. Our ecosystem is dependent on biodiversity, and we must prevent species extinction in order to maintain the health of our environment. It is a difficult undertaking, and environmental listings are frequently misplaced. There is yet time to save endangered species and avert the extinction of current species.

As one of the best environmental project topics, you can create a “green living tip sheet” and distribute it to your community or network online. Recognize an environmental group or a community leader for their work. Track maintenance can be done as a volunteer with your local park agency. You’ll make it easier for more people to enjoy the outdoors! Make a weekly commitment to “Meatless Mondays,” or avoid eating meat for one day. Collect and give used smartphones to those in need.


You can make a difference in the environment. Everyone has the power to contribute to environmental protection. However, we now face more critical difficulties than ever before in order to ensure that the Earth stays habitable for future generations. As our population grows, environmental challenges will become more severe, needing more drastic solutions and modifications. Whether you decide to pursue a career in environmental science and strive to address some of these issues or simply educate yourself on current environmental science project subjects to raise awareness, you are helping to maintain a healthy environment.
