Industrial activities currently still rely heavily on the use of carbon. Take power generation facilities as an example, particularly those harnessing energy from coal and natural gas. They're at the very top of the list of the largest carbon emitters. Meanwhile, the process of steel production requires the combustion of coke, a carbon-rich derivative of coal, leading to substantial CO2 emissions. Furthermore, cement manufacturing necessitates the heating of limestone, which in turn emits CO2. Chemical processing typically involves heat and catalytic reactions that release GHGs into our atmosphere.
These industrial processes, among others, are the root cause of the rapid build-up of GHGs in our atmosphere. This accumulation exacerbates the greenhouse effect - the natural occurrence whereby gasses in Earth's atmosphere trap the sun's heat. As this effect intensifies, it raises our planet's average temperature, setting the stage for the dire consequences of climate change.
A Brief Look at Carbon-Intensive Industries
Industries worldwide significantly contribute to carbon emissions, bringing the need for decarbonization to the forefront. Some of the top carbon-emitting sectors include energy production, manufacturing, and transportation. These sectors each have unique challenges in achieving decarbonization, as well as unique potentials for making it a reality.
Energy Production
The energy sector is one of the largest contributors to global greenhouse gas emissions. The burning of fossil fuels such as coal, oil, and natural gas for power generation and heat produces significant amounts of carbon dioxide. For instance, coal-fired electricity generation alone accounted for 30% of global CO2 emissions in 2018. Decarbonizing the energy sector, therefore, requires a shift towards cleaner and renewable sources of energy like wind, solar, and hydro. This includes reducing reliance on coal, promoting energy efficiency, and transitioning to renewable energy technologies. Such initiatives could potentially significantly lower carbon emissions from this sector if adequately implemented.
Manufacturing
The manufacturing sector, which involves the production of goods ranging from food products to machinery, also contributes significantly to global emissions. Around 22% of global CO2 emissions come from industry, including manufacturing and construction. A significant share of these emissions originates from energy-intensive industries such as steel, cement, and chemical manufacturing. To reduce carbon output, the manufacturing sector can enhance energy efficiency, switch to low-carbon fuels, and implement carbon capture and storage technologies. Additionally, innovation and sustainability in manufacturing processes, such as recycling resources and utilizing green building materials, can further contribute to decarbonisation efforts.
Transportation
Lastly, the transportation sector contributes 24% of direct CO2 emissions from fuel combustion, with road vehicles accounting for nearly three-quarters of these emissions. A myriad of approaches is being explored for decarbonizing the transport sector. These include adopting cleaner fuels, improving fuel efficiency, developing electric vehicles, and optimizing logistics and transport infrastructure. For instance, electric vehicles (EVs) provide a promising option for decarbonization because they produce no tailpipe emissions and tend to be more efficient than conventional vehicles. Further investment in EV infrastructure and technologies can significantly reduce carbon emissions from this sector.
Various industries worldwide offer both unique opportunities and obstacles when it comes to applying decarbonisation methods. To make significant progress, an all-inclusive understanding and method is necessary, one that takes into account the distinct situations and necessities of each sector. The global push towards a more sustainable and low-carbon economy hinges on the success of these industrial decarbonization endeavors.
Understanding Industry Decarbonization
Industry decarbonization is a term that refers to the methods of reducing carbon emissions that are produced out of industrial activities. This approach is multi-faceted; it involves the enhancement of energy efficiency, the switch to lower-carbon fuels, the deployment of carbon capture, use, and storage (CCUS), and comprehensive transformation of industrial processes.
One way this can be achieved is through improving energy efficiency. By doing so, industries can lower the amount of energy needed for operations, which in turn reduces carbon emissions. The transition from high-carbon fuels such as coal to lower-carbon options like natural gas or renewable energy sources can significantly cut CO2 emissions as well.
Carbon capture technologies hold a vital role in the decarbonisation of industries. These technologies trap and condense CO2 before it can seep out from smokestacks and either they store it underground or use it in other industrial processes. Carbon capture doesn't only minimize the impact of existing facilities, but can also assist in cleaning up newer, more efficient industrial processes.
Another key method towards decarbonization involves transforming industrial processes to utilize electrolytic methods or develop new materials which require less energy-intensive production processes.
In our next article we will dive deeper into the role of innovation and technology in achieving decarbonization.
