Answer: Carbon capture and storage systems
Answer Explanation:
The carbon capture and storage system is a method of reducing carbon dioxide emissions, which could be key to helping to tackle global warming. It is a three-step process that includes capturing the CO2 produced by power generation or industrial activity, such as hydrogen production, steel or cement making, transporting it; and then permanently storing it deep underground.
Carbon capture and storage technologies are measures of mitigation designed to reduce CO2 emissions from energy and other energy-intensive industries. Carbon capture and storage is an important technology for decarbonising the world economy. The primary goal of carbon capture and storage is to keep anthropogenic CO2 from entering the atmosphere by capturing and permanently storing it in different carbon sinks.
The Intergovernmental Panel on Climate Change stated that if we are to meet the Paris Agreement’s ambitions of limiting future temperature increases to 1.5°C, we must do more than just increase efforts to reduce emissions; we must also deploy technologies to remove CO2 from the atmosphere. Carbon capture storage systems are one of these technologies, and they can play an essential role in combating global warming.
Single-use plastic packaging: Single-use plastics contribute to waste pollution, especially in oceans and landfills. Plastic production relies on petroleum-based materials, which are not sustainable.
Blockchain used for cryptocurrency mining: Cryptocurrency mining requires huge amounts of energy, often from non-renewable sources like coal. This leads to high carbon emissions and environmental degradation. While blockchain technology can be used for sustainable applications, mining cryptocurrencies is widely seen as energy-inefficient and unsustainable.
Gasoline-powered vehicles with turbo engines: These vehicles still rely on fossil fuels, which emit carbon dioxide and other pollutants. Even with turbo engines, they do not eliminate pollution or contribute to long-term sustainability.
