Moving towards zero carbon: Why is "net zero emissions" crucial to the world?

Many countries have recently announced significant commitments to significantly reduce their carbon emissions and commit to achieving "net zero emissions" within the next few years. This word is becoming a necessary step towards successfully curbing climate change and its destruction.  
What is net zero emissions and why is it important?
In short, net zero emissions means that we will not add new emissions to the atmosphere. Although emissions will continue, they can be absorbed equally by the atmosphere to achieve equilibrium.  
Almost every country has acceded to the Paris Agreement on Climate Change, which calls for controlling global warming at a level of 1.5 ° C above pre industrial levels. However, if we continue to emit substances that cause climate change, the temperature will continue to rise above 1.5 ° C, even threatening the lives and livelihoods of people around the world.  
This is why more and more countries are committed to achieving carbon neutrality or "net zero emissions" in the coming decades. This is a difficult task that requires immediate action.  
Our goal is to achieve net zero by 2050. However, countries also need to demonstrate how to achieve this goal. Efforts to achieve zero emissions must be complemented by climate adaptation and resilience measures, as well as climate finance for developing countries.  
How can the world go to net zero?  
The good news is that there are currently available technologies to achieve net zero emissions at a reasonable price.  
A key factor is promoting economic development with clean energy, replacing polluting coal with renewable energy sources such as wind or solar energy, and natural gas and oil fired power plants. This will significantly reduce carbon emissions. In addition, renewable energy is now not only cleaner than fossil fuels, but also generally cheaper.  
A comprehensive shift towards electricity transportation powered by renewable energy will also play a significant role in reducing emissions, while also having the benefits of reducing air pollution in major cities around the world. Electric vehicles are rapidly becoming cheaper and more efficient, and many countries, including those committed to achieving net zero emissions, have proposed plans to phase out the sale of fossil fuel powered vehicles.  
Other harmful emissions come from agriculture (livestock produce large amounts of greenhouse gas methane). If we eat less meat and more plant based foods, we can significantly reduce these emissions. The global trend in this area is once again encouraging. For example, "plant based meat" food sold by some major international fast food chains is becoming increasingly popular.  
What about the remaining emissions?  
To achieve zero net worth, we also need to find ways to decarbonize from the atmosphere. Similarly, there are solutions in nature. These "natural based solutions" include forests, peat swamps, mangroves, soil, and even underground algal forests, which can absorb carbon very effectively.
Reducing emissions is extremely important.
This is why the world is making tremendous efforts to save forests, plant trees, restore peat and mangrove areas, and improve farming techniques.  
Some important climate-related facts
Earth warming
The temperature of the earth is now 1.1 degrees Celsius higher than at the beginning of the industrial revolution. The Paris Climate Change Agreement of 2015 stipulates that the global temperature rise should be much lower than pre industrial levels by 2 degrees Celsius, or at 1.5 degrees Celsius.
Future trends
2010-2019 was the hottest decade on record. According to current trends in carbon dioxide emissions, global temperatures are expected to rise by 3-5 degrees Celsius by the end of this century.
Reducing fossil fuels
To avoid the worst form of warming (up to 1.5 degrees Celsius), the world needs to reduce fossil fuel production by approximately 6% annually between 2020 and 2030. Instead, countries are planning and forecasting an annual growth rate of 2%.
Increase employment
Climate action is not a budget breaker or an economic breaker: in fact, turning to a green economy will increase employment opportunities. Compared to business as usual, it will generate $26 trillion in direct economic benefits by 2030. This may only be a conservative estimate.
Who is responsible for achieving net zero emissions?  
All of us have a responsibility to make our lifestyle more sustainable. The private sector also needs to take action, and it is doing so through the United Nations Global Compact, which can help companies align with relevant environmental and social goals of the United Nations.  
However, it is clear that the main driving force for change will be at the national government level, such as through legislation and regulations to reduce emissions.  
Many governments are now moving in the right direction. By the beginning of 2021, countries that account for over 65% of global carbon dioxide emissions and over 70% of the world economy will make ambitious commitments to carbon neutrality.  
The European Union, Japan, South Korea, and more than 110 other countries have pledged to achieve carbon neutrality by 2050. China says it will achieve carbon neutrality by 2060.
