The planet we live on has been going through significant changes in the past few decades. One of the most significant changes is the increase in atmospheric carbon dioxide (CO2) levels. The concentration of CO2 in the atmosphere is currently at its highest in 800,000 years. The last time the concentration was this high, the temperature of the world was 3-6 degree Celsius warmer than the present day.

The effects of global warming are now becoming visible to the naked eye. The rising sea levels, biodiversity loss, and extreme weather conditions are some of the consequences of the human-induced carbon emission. It is imperative to mitigate the emission of carbon to prevent dangerous levels of global warming. The world leaders agreed on limiting global warming below 2 degrees Celsius in the Paris Agreement in 2015. The question is, how can we achieve this goal in the current scenario when the emission levels are still high?

Before we delve into the solutions, it is essential to understand that the concentration of CO2 is not the only factor that determines the temperature of the world. Other greenhouse gases like methane, nitrous oxide, and chlorofluorocarbons (CFCs) also contribute to global warming. The reduction of those gases is equally significant in achieving the goal of limiting warming below two degrees Celsius.

The approach to reduce carbon emission is multi-pronged. The first step is to reduce the dependency on fossil fuels. The transportation sector is the largest contributor to carbon emission. Replacing gasoline and diesel-powered vehicles with alternative energy-powered or electric vehicles can significantly reduce the carbon footprint. The growth of renewable energy such as solar, wind, and hydro power is another approach to reduce carbon emissions. The International Energy Agency predicts that renewable energy will make up almost half of the world’s energy production by 2040.

The next step is the carbon capture and storage (CCS) technology. The CCS technology captures CO2 from industrial processes and stores it in underground formations. The captured carbon can also be utilized for industrial purposes like making concrete. The deployment of CCS technology can significantly reduce carbon emissions from industries like power plants and cement production.

Finally, the behavior of individuals and organizations also plays a significant role in reducing carbon emissions. Choosing low-carbon alternatives like using bicycles instead of cars, reducing the use of non-biodegradable products, and choosing locally-sourced products can reduce the carbon footprint. Businesses can also reduce carbon emissions by promoting telecommuting and green supply chains.

In conclusion, reducing the world’s carbon footprint is a collective responsibility. It requires the collaboration of governments, businesses, and individuals. The decarbonization of the economy is one of the biggest challenges the world is facing today, but it is also an opportunity to develop clean energy and create a sustainable future for the planet. By adopting an integrated approach and deploying innovative solutions, we can limit global warming below two degrees Celsius and safeguard the planet for future generations.
