The Impact of Manufacturing on Climate Change
Manufacturing Processes and Climate Change
Manufacturing processes are diverse and involve a wide range of commodities traded globally, making the analysis of their impact on climate change complex. Climate change affects the manufacturing sector by influencing the security of electricity supply, availability of transportation, and access to water. These factors are critical for manufacturing operations, and their disruption can lead to significant negative impacts on production processes by the 2040s, potentially worsening in the latter half of the century without effective global action1.
Climate Change Effects on Manufacturing Productivity
Climate change poses a significant threat to the manufacturing sector, affecting productivity, business risk, and the availability of natural resources. Severe weather conditions, such as increased temperatures and precipitation, negatively impact manufacturing outputs. For instance, in Nanjing, China, higher average temperatures and precipitation levels have been shown to reduce manufacturing productivity, although warmer winter temperatures can have a beneficial effect2 4.
Mitigation Technologies in Manufacturing
The adoption of climate change mitigation technologies is crucial for controlling greenhouse gas emissions in the manufacturing sector. Technologies such as low-carbon energy, eco-efficiency, and green design can significantly enhance the environmental performance of manufacturing firms. However, not all technologies have the same impact; for example, low-carbon energy technology positively affects firm performance, while pollution control technology can have a negative effect3 10.
Energy Intensity and Technological Innovation
Decoupling manufacturing production from energy use is essential for mitigating climate change. Technological advancements play a fundamental role in reducing energy intensity in manufacturing. Studies have shown that capital-energy substitution and technological progress significantly contribute to improvements in energy intensity, particularly in developed economies7. Low-carbon technology innovation (LCTI) is particularly effective in enhancing environmental performance, as evidenced by increased carbon efficiency and productivity in OECD countries10.
Supply Chain Risks and Climate Change
Climate change also impacts global supply chains, affecting food production, natural resources, and transportation. Extreme weather conditions can disrupt supply chains, leading to cascading effects across interconnected sectors. Effective management of climate change risks in supply chains is essential to mitigate these impacts and ensure business continuity8.
Policy Implications and Adaptation Strategies
Manufacturing industries must adapt to climate change by implementing various strategies, including continuous staff and management training on climate change, and integrating climate considerations into factory planning. Carbon accounting is also becoming increasingly important for managing climate change risks and making informed decisions to mitigate environmental impacts2 6 9.
Conclusion
Manufacturing significantly affects and is affected by climate change. The sector faces challenges related to productivity, resource availability, and supply chain disruptions due to severe weather conditions. However, the adoption of climate change mitigation technologies and innovative practices can enhance environmental performance and reduce energy intensity. Policymakers and industry leaders must prioritize adaptation strategies and technological innovations to mitigate the adverse effects of climate change on manufacturing.
