Carbon dioxide (CO2) is good at holding in heat from the Sun, and even a small increase of the gas in the atmosphere can cause Earth to get even warmer. Carbon capture, usage and storage (CCUS) is about different technologies that can keep CO2 produced by factories and power plants from causing global warming. The idea is simple, and there are only a few main steps in the process. The first step is about trapping carbon emissions from factory chimneys. For instance, a filter can be placed in the chimney, so that the carbon is trapped and it cannot go out into the atmosphere. Then, the gas is piped to places where it can be stored or used. If stored underground, it cannot contribute to the climate crisis. If used, for instance, it can help grow greenhouse plants or make soda drinks. While CCUS projects can clearly benefit the environment, these projects are not straightforward as there are many issues to be dealt with, such as maintaining the storage site, which have slowed start-ups of CCUS projects worldwide. Thus, with only a few CCUS projects operating now, there still aren’t enough to seriously help with the world’s carbon emissions. Early forerunners in this technology are the US, Canada, and Norway. The good news is that CCUS has now gained momentum in other countries, where 30 new projects have begun in the past three years. The International Energy Agency says there must be many more to keep carbon emissions from heating the world too much.

- A To trap the CO2, and then either keep it or use it.
- B To use the CO2, and then store it in greenhouse plants.
- C To pipe the CO2, and then trap it to cause the climate crisis.
- D To store the CO2 underground, and then pipe it to the chimneys.
