Abstract
Climate change is a pressing global crisis that demands urgent and effective solutions. Environmental law, as a legal framework governing human interaction with the natural environment, plays a significant role in mitigating and adapting to this challenge. This research explored the strategies employed by environmental laws to address climate change. Nigerian environmental laws, United States of America environmental laws, African Regional environmental laws and international environmental laws were examined. Environmental laws establish regulations to reduce greenhouse gas emissions, the primary driver of climate change. The paper adopted the doctrinal method of research where both primary and secondary materials were used. The primary materials used were statutes, the 1999 Constitution of the Federal Republic of Nigeria, as amended, Environmental Impact Assessment Act 1992, National Environmental Standards and Regulation Enforcement Agency (NESREA) Act 2007. The secondary sources included textbooks, journals and online sources. While environmental laws offer a valuable tool in combating climate change, challenges remain. The challenges faced are complexity and global nature of climate change, economic impacts and industry resistance, technological and scientific challenges. The following findings were discovered in my research, the effectiveness of current environmental laws needs for innovative legal instrument to promote international cooperation and coordinated action on climate change. The paper recommended, the reforming of existing laws or reinterpreting them to incorporate climate-specific challenges and adaptive mechanisms. Develop and adopt harmonized environmental standards and regulations to reduce discrepancies between jurisdictions.
