Energy saving and emission reduction refers to saving material and energy resources, and reducing the discharge of waste and environmental hazards (including three wastes and noise). Next, I will bring you a lecture on energy conservation and emission reduction for college students, hoping to help you with your work and study.

Energy-saving and Emission-reduction Topic University Students' Speech 1 Energy-saving and Emission-reduction You and I Walk Together.

With the rapid development of economy and society, human beings are too eager for the satisfaction and speed of development, and ignore or weaken its negative effects. "Energy saving and emission reduction" is not only a problem caused by environmental pollution such as enterprise production and automobile exhaust emission, but also a lot of hidden dangers for their future development.

In order to save energy and reduce emissions, we must start with small things, and everyone should start with their hands. I put forward the following feasible suggestions:

First, save electricity. Turn off the lights, you can use high-efficiency and energy-saving light bulbs. According to the estimation of the U.S. Department of Energy, replacing traditional light bulbs with energy-efficient light bulbs can reduce 400 million tons of carbon dioxide emissions. In addition to electric lights, our company should also control the production and use of machines, and try to achieve low-consumption and energy-saving products. When we are not using the machine, we should cut off or turn off the power. When using the air conditioner, don't adjust the temperature too low, just about 26℃.

Second, save water resources. The air-conditioned water received in the factory can be used for washing hands, wiping tables and mopping the floor. Turn off the tap after running water, and keep the floor intact after mopping the floor. When the machine water source is available for production, don't put it too big to reduce sewage discharge and environmental pollution.

Third, save paper. The recycling of paper can avoid methane released by landfill and reduce the felling of trees. According to statistics, recycling one ton of waste paper can produce 800 kilograms of recycled paper, which can reduce the felling of 17 trees. Companies should try not to waste printing paper, replace good paper with single-sided paper, make mistakes in printing and writing, or run out of reference documents, and don't throw away what can be recycled as garbage. This is not only to reduce company costs, but also to protect forest resources.

Fourth, reduce tail gas emissions. The city is filled with smoke from burning garbage and products produced by companies. We should treat and filter the waste gas before discharging it to reduce pollution.

Five, garbage classification and treatment. Garbage sorting can recycle valuable resources and reduce the energy consumed by landfill and incineration. For example; Beverage bottles, cans, plastics, cartons and waste paper become renewable resources; Classify and recycle garbage every day, and try to turn waste into treasure.

Market competition and rising prices have sounded the alarm for us. Let's act together to save energy and reduce emissions, save costs for the company, get more profits and strive for better welfare for ourselves.

Keynote Speech on Energy Saving and Emission Reduction for College Students 2 Dear teachers and students,

Hello everyone!

Today, the topic of my speech under the national flag is "saving energy and living a low-carbon life". Once upon a time, we thought that the earth we lived in was a beautiful planet wrapped in blue tulle. However, in recent years, the living environment of the earth is increasingly pessimistic, and natural disasters such as volcanoes, earthquakes and tsunamis occur frequently. Once upon a time, we naively thought that the energy left by Mother Earth was inexhaustible. However, the latest statistics show that oil will be exhausted within 60 years, and coal can only be used by human beings for another 250 years. All this gives us a severe warning: it is urgent to protect the environment and cherish resources, and the most effective means to improve the earth's environment and protect the earth's resources is to save energy and realize a low-carbon life.

As we all know, when a car starts and burns engine oil, it will emit waste gas containing carbon dioxide; Power plants, industrial production, etc. It is also necessary to emit waste gas containing carbon dioxide, which is the cause of global warming and frequent disasters. Low-carbon life is to reduce energy consumption as much as possible in daily life, thus reducing carbon dioxide emissions. Below I will provide some data to the students, and you will have a more real feeling.

If we turn on the air conditioner for one hour less, we can reduce carbon emissions by 621g; If you watch TV for one hour less, you will reduce your carbon emissions by 96g. Saving primary electricity will reduce carbon emissions by 639g. If China acts together, we can reduce our carbon emissions by about 29 billion kilograms every day. What a huge amount of data this is!

Each of us is the master of the earth, and it is everyone's responsibility to actively practice a low-carbon life and be the guardian of the earth.

My speech is over, thank you!

Keynote Speech on Energy Saving and Emission Reduction for College Students 3 Dear students:

Hello, everyone, I'm _ _ from Class _ _, and the topic of my speech today is "Energy Saving and Environmental Protection, Low Carbon Life".

In recent years, with the rapid development of economy, the contradiction between economy and environment has become increasingly acute. Water pollution, sandstorm, soil erosion, floods and droughts, environmental pollution and destruction have seriously threatened human health and survival.

As the master of 2 1 century, every student should have a sense of responsibility to protect the environment. Although we are still students now, we can start from the small things around us, from caring for the school environment, and "look around the world, pay attention to our side and base ourselves on the campus".

We should start with saving a piece of paper, a drop of water, electricity and a grain of rice, strive to be a "low-carbon family", develop the habit of energy conservation and environmental protection, enjoy a green and healthy life and care for mankind.

The main mode of power production in China is still thermal power station, which needs to burn a lot of coal and cooling water in the process of power production, and the carbon emissions generated are still considerable. The thermal power station needs about 0.4 kg of standard coal and 4 liters of cooling water to produce primary electricity, and correspondingly produces 0.997 kg of carbon dioxide, 0.03 kg of sulfur dioxide, 0.0 15 kg of nitrogen oxides and 0.272 kg of carbon dust. One degree of electricity can keep a 25-watt lamp on for 40 hours, or ensure a refrigerator to run for 24 hours.

There is still a phenomenon of ever-burning lamps in our school. Students turn on the tap because they wash their hands too much. Dumping food in a restaurant is an act called "big eyes and small belly". If you buy too much food, you can't eat it or throw it away.

"Don't do small good, don't do small evil". Each of us should form good hygiene habits. We won't stop and pick up a piece of paper; Clean up a pile of rubbish; Cherish a flower and a tree; Take care of a grass. As high school students, we can do this:

1, see enough light, can actively turn off the classroom lights.

2. When you see that the faucet is not closed tightly, you can tighten it forward.

3. Buy as much as you want when eating, don't compare, don't waste, don't eat snacks, and try to reduce the use of napkins; Domestic garbage should be classified to facilitate recycling.

4. Unused exercise books can be used as drafts. Try to use both sides of the paper, and then change the refill when it is used up;

5. Walk more, ride more bicycles and take more buses.

6. Buy less unnecessary clothes. An ordinary garment, from raw materials to ready-made clothes, will emit carbon dioxide when it is finally discarded. Buying less unnecessary clothes can reduce carbon dioxide emissions. In addition, cotton-padded jacket emits less carbon than chemical fiber clothes, and wearing cotton-padded jacket and school uniforms is also part of a low-carbon life.

If you can do the above, then you are a good student who saves resources and practices a low-carbon life ... The "low-carbon family" is using the changes in their own life details to prove that climate change is no longer just a concern of environmentalists, government officials and experts and scholars, but is closely related to each of us. Nowadays, advocating healthy living has become a trend. "Low-carbon life" is no longer just an ideal, but also a new lifestyle worth looking forward to.

Let's take active actions, starting from you and me, starting from small things, starting from the side, starting from now. Take care of our beautiful campus with practical actions.

Keynote Speech on Energy Saving and Emission Reduction for College Students 4 Dear teachers and students, hello everyone:

The theme of my speech today is: save resources, cherish the earth, protect the environment, and be a qualified little environmental guardian!

We once praised our motherland so proudly: vast territory and abundant resources, magnificent mountains and rivers! As we all know, China is the largest developing country in the world with a large population. Someone once put forward such a profound multiplication and division method: "What a small problem, multiplied by 65.438+0.3 billion, will become very big, and what a big economic aggregate, divided by 65.438+0.3 billion, will become very small." For example, the total amount of fresh water in China is 2.8 trillion cubic meters, which is not rich at all. Divided by 65.438+0.3 billion, the per capita fresh water resources are only 2,200 cubic meters, only a quarter of the world average! Vibrant forests are very rich and have the reputation of "lung of the earth". However, the per capita forest area in China ranks behind 120 in the world, and now it is rapidly decreasing at a rate of more than180,000 hectares per year. The reduction of forests makes the climate worse and causes serious soil erosion. The Yellow River, once the mother river of China, has become downright "surly".

Teachers and students, what should we do for the sustainable development of mankind and the beautiful home of the earth in the face of the deteriorating environment?

We should save every drop of water. Remember to turn off the tap at hand. Don't think that a few drops of water in the tap are nothing. A drop of water per second from the tap is 36 cubic meters of water a year. We should actively look for "golden ideas" to save water in our lives: for example, watering flowers, washing mops, washing toilets, etc. , and recycling.

We should save every kilowatt hour. Turn off the lights, use the air conditioner rationally, find common sense of saving electricity and practice hard. Actively use clean energy such as solar energy, wind power generation and tidal power generation. We should save every piece of paper. Use homework paper on both sides, use more handkerchiefs and less paper towels. If each of us saves a piece of paper every day, the country can save 474.5 billion pieces of paper a year and cut less 158 a year. 16.66 million trees. In this sense, saving paper means creating forests.

We should advocate green travel. Automobile exhaust contains a lot of carbon dioxide, which will have a "greenhouse effect" on the earth. Driving one day less and riding a bike one day more can not only make the air fresher, but also exercise our bodies.

We should advocate the use of environmental protection bags. Because the burning of plastic bags will produce a lot of toxic gases, pollute the atmosphere, and it is not easy to degrade, which will destroy our land, so we should try our best to reduce "white pollution".

Saving resources and protecting the environment need everyone's strength. Students, let's take action and be a little environmental guardian who saves resources and cares for the earth!

Topic of energy saving and emission reduction: 5 Dear leaders, teachers and dear students:

Hello everyone!

When you ride a bike on the vast land and see green mountains and green waters and picturesque scenery, it will be pleasing to the eye; When you fly high in the sky and see the blue sea and blue sky, you will feel relaxed and happy; When the rain clears and a gorgeous rainbow hangs in the blue sky, you will definitely feel how clear the sky is! How fresh the air is! ! Have you ever thought: green mountains and green waters, blue sky and blue sea, earth and rivers are the resources of our lives! Home of survival! !

In my school, teachers often teach us to save resources and care for the environment, starting from bit by bit. On campus, environmental protection and civilized actions are in full swing. Every student is trying to be a little guardian of environmental protection. You pick up a piece of paper, I sweep a leaf, everything is clean and tidy. I also know that protecting the environment is everyone's responsibility! Save resources, start with me! I am determined to be an excellent little environmental defender! So, I put away my grandfather's old batteries for shaving, picked up the plastic bags used by my grandmother, turned off my father's computer in standby mode, screwed up my mother's loose faucet, and saved my textbooks for my brothers and sisters in our school. Promote environmental protection knowledge such as "green consumption, environmental protection purchase, reuse, garbage sorting" to family members, and tell family members the case that environmental protection families don't need disposable chopsticks and teacups. ...

Saving a piece of paper, a drop of water, electricity and electricity, being civilized, polite and hygienic may seem insignificant, but water can gather into rivers and sand can gather into towers! A small step for family environmental civilization, a big step for social environmental civilization! Today, we don't throw away a waste battery, pick up a plastic bag and use disposable chopsticks less, leaving a pool of clear water, a pure land and a blue sky for tomorrow! Today, we are holding hands with small hands, driving more families to save resources and care for the environment. Tomorrow, we can join hands to make our sky bluer, our grass greener, our water cleaner and our environment better and better! Our resources are getting richer and richer! Our society is becoming more and more civilized! Progress! ! Students, let's act. Let's be little guardians of environmental protection!

Thank you!
