In recent years, we have seen a manifold increase in natural calamities resulting from the continual degradation of our environment. The overuse of fossil fuels and other natural resources has contributed towards increasing global warming. This research investigates the environmental challenges posed by the overuse of natural resources and the subsequent carbon footprint. It emphasises the critical need for green technology and cleaner production practices to overcome environmental challenges. Focusing on developing countries, it investigates the effects of green technology and cleaner production-practices on energy efficiency, waste reduction and corporate sustainability in Pakistan's manufacturing industry. Through a cross-sectional analysis, it investigates the influence of sustainable practices on corporate sustainability in diverse manufacturing sectors. The findings reveal a positive correlation between the adoption of green technology and cleaner production-practices and a reduction in energy consumption, highlighting the significant role of resource commitment in enhancing the effectiveness of green technologies. However, the study notes a lack of significant impact of green technology on waste reduction and the broader concept of corporate sustainability, while cleaner production-practices show a beneficial influence on sustainability measures. This study contributes to the understanding of sustainable practices in emerging economies and underscores the importance of top management support and resource allocation in achieving environmental and economic sustainability goals.
