This study discusses the importance and role of renewable energy in reducing carbon emissions, Given the importance of this subject in the light of the climate challenges currently facing the world, Where CO2 emissions are one of the largest causes of environmental pollution and global warming produced through human activities such as fossil fuel consumption, This study aims to learn about the role of renewable energy in reducing CO2 emission, Such as sun, wind and water energy, this study highlights the importance of increasing reliance on these sources as an alternative to non-renewable energy. This study also discusses previous research confirming that renewable energy plays a crucial role in reducing this emission as well as the challenges of shifting towards these sources.

This study's objective was to evaluate the environmental risks associated with construction, keeping in mind that the 1980s saw a sharp increase in the building sector as a result of the increased demand for residential space. The study also addressed the significance of understanding how construction affects the environment, the need to raise awareness, and the necessity of using resources wisely in residential projects.An essential instrument for ensuring that the construction project's negative consequences are minimized and its positive ones are maximized across its entire life cycle is the environmental construction management plan. The report also emphasizes how accidents occur in building projects and how they affect both the environment and the workers.
