As the urgency to address climate change intensifies, global efforts have increasingly focused on reducing greenhouse gas (GHG) emissions, with particular attention to minimizing carbon footprints. This review article synthesizes the innovative approaches developed between 2010 and 2024 across various sectors to achieve significant GHG reductions. Notable advancements in renewable energy technologies, such as solar photovoltaic (PV) and wind energy, have been central to these efforts, offering more efficient and cost-effective alternatives to fossil fuels. These technologies are further supported by smart grid systems, which enhance the integration of renewable energy into existing power grids and address challenges related to energy intermittency.

In the industrial sector, carbon capture, utilization, and storage (CCUS) technologies have emerged as vital tools for mitigating emissions from industries where decarbonization is particularly challenging, such as cement and steel production. While promising, the broader application of CCUS is hindered by scalability issues and high costs, highlighting the need for continued innovation and policy support.

Behavioral changes also play a critical role in reducing GHG emissions. The review identifies sustainable consumption practices, such as reduced meat intake, waste minimization, and the adoption of energy-efficient technologies, as effective strategies for lowering individual carbon footprints. In transportation, the increasing adoption of electric vehicles (EVs) and enhancements in public transportation infrastructure are pivotal in reducing emissions from this sector.

Policy frameworks, including international agreements like the Paris Agreement and local climate action plans, are crucial in driving these technological and behavioral changes. These policies provide the necessary incentives and regulatory support to accelerate the transition to a low-carbon economy.
