  Building a carbon-neutral world needs to remove the excess CO$_2$ that has
already been dumped into the atmosphere. The sea, soil, vegetation, and rocks
on Earth all naturally uptake CO$_2$ from the atmosphere. Human beings can
accelerate these processes in specific ways. The review summarizes the present
Direct Air Capture (DAC) technology that contribute to Negative Emissions.
Research currently being done has suggested future perspectives and directions
of various methods for Negative Emission. New generations of technologies have
emerged as a result of recent advancements in surface chemistry, material
synthesis, and engineering design. These technologies may influence the
large-scale deployment of existing CO$_2$ capture technologies in the future.
