Introduction to our series on Decarbonization
Consider this: many of the everyday products we rely on are birthed from industries that greatly contribute to climate change. Think about power generation, steel production, cement manufacturing, and chemical processing. These sectors regularly spew vast quantities of greenhouse gasses (GHGs) like carbon dioxide (CO2) and methane (CH4) into our atmosphere. GHGs trap the Earth's heat, leading to an increase in the planet's overall temperature, a condition we know all too well as global warming.
Emissions originating from the industrial sector are substantial. According to the Global Carbon Project, this sector contributed to approximately 20% of global emissions in 2020 from energy use alone. This underscores the clear connection between the industrial sector and climate change, and the urgency to address this issue.
This has led to one of the most imperative challenges we face today being the decarbonization of industry. With industries like manufacturing, energy production, and transportation being amongst the heaviest carbon emitters, their roadmap towards reducing these emissions forms a key element of the climate change solution.
This introductory article is the first part of a four part series. In the coming articles we will dive into carbon-intensive industries before discussing the role of technology in mitigating emissions. Finally, the discussion will delve into the challenges industries encounter during decarbonization and the innovative solutions available, supported by real-world examples of successful decarbonization efforts.
Understanding Decarbonization
Industry decarbonization is a term that refers to the methods of reducing carbon emissions that are produced out of industrial activities. It is achieved through the use of low carbon power sources, the adoption of carbon capture and storage methods, and the redesign of manufacturing processes, among other strategies. Decarbonization aims not only to lower carbon dioxide levels in the atmosphere but also to mitigate and reverse the impacts of climate change.
Decarbonization should not be confused with other related terms like de-carbonization and carbon neutrality. De-carbonization refers to the sustainable use and management of carbon stored in ecosystems, whereas decarbonization specifically focuses on reducing CO2 emissions. On the other hand, carbon neutrality refers to achieving a balance between emitting carbon and absorbing carbon from the atmosphere in carbon sinks, primarily through the process of photosynthesis by plants and trees.
Challenges & Opportunities in Industrial Decarbonization
Industries have a significant role to play in the process of decarbonization. They can make substantial contributions to CO2 emissions reduction through strategic changes within operations, production processes, and supply chains. This transition can be through energy efficiency improvements, increasing the use of renewable energy, electrification of processes, carbon capture and storage, and innovative technologies like hydrogen power.
Industry decarbonization is essential not just for the environment but also from an economic perspective. As governments across the globe begin imposing penalties for high levels of greenhouse gas emissions, industries that have adopted decarbonization strategies will likely be better positioned to avoid these costs. Additionally, consumers and investors are increasingly demanding sustainability-focused practices from businesses, rewarding those companies that prioritize decarbonization with increased sales and investment.
Most importantly though, successful implementation of decarbonization in industries is predicted to substantially slow down climate change by reducing the amount of greenhouse gasses in the atmosphere. According to the Intergovernmental Panel on Climate Change (IPCC), to limit global warming to 1.5 degrees Celsius and avoid the worst impact of climate change, it requires global carbon emissions caused by humans to drop about 45% from 2010 levels by 2030 and reach 'net zero' by around 2050.
Despite the known benefits, decarbonization comes with its unique set of challenges. High up-front costs, the need for technological advancements, infrastructural changes, and regulatory support are some hurdles. Despite these, there are also numerous opportunities associated with decarbonization, including the creation of new jobs in the renewable energy sector, improved public health due to better air quality, and the potential for export growth in industries developing low carbon technologies.
Conclusion
Given the urgency of addressing climate change, decarbonization serves as a pivotal strategy. With its power to markedly diminish greenhouse gas emissions, while simultaneously stimulating economic growth, decarbonization isn't just an option - it's a necessity. As we delve deeper into sustainable development, it becomes increasingly clear that decarbonization is central to mitigating the effects of climate change.
