⭐ Core Definition: Decarbonization

Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO2) from the atmosphere. Recent assessments emphasize that global greenhouse gas emissions must peak before 2025 and decline by about 43% by 2030 to limit warming to 1.5 °C, requiring rapid transitions in energy, transport, and land-use systems. Current climate change mitigation policies are insufficient as they would still result in global warming of about 2.7 °C by 2100, significantly above the 2015 Paris Agreement's goal of limiting global warming to below 2 °C.Recent research shows that demand-side climate solutions—such as shifts in transportation behavior, dietary change, improved building energy efficiency, and reduced material consumption—could reduce global greenhouse gas emissions by 40% to 70% by 2050 while improving human well-being.A 2023 study published in Nature Energy found that rapidly expanding global solar and wind capacity could reduce energy-sector carbon dioxide emissions by up to 6.6 gigatonnes per year by 2035, making renewable energy one of the most cost-effective pathways for climate change mitigation.

Solar energy and wind power can replace fossil fuels at the lowest cost compared to other renewable energy options. The availability of sunshine and wind is variable and can require electrical grid upgrades, such as using long-distance electricity transmission to group a range of power sources. Energy storage can also be used to even out power output, and demand management can limit power use when power generation is low. Cleanly generated electricity can usually replace fossil fuels for powering transportation, heating buildings, and running industrial processes. Certain processes are more difficult to decarbonise, such as air travel and cement production. Carbon capture and storage (CCS) can be an option to reduce net emissions in these circumstances, although fossil fuel power plants with CCS technology is currently a high-cost climate change mitigation strategy.

👉 Decarbonization in the context of Heavy industry

Heavy industry is an industry that involves one or more characteristics such as large and heavy products; large and heavy equipment and facilities (such as heavy equipment, large machine tools, huge buildings and large-scale infrastructure); or complex or numerous processes. Because of those factors, heavy industry involves higher capital intensity than light industry does, and is also often more heavily cyclical in investment and employment.

Though important to economic development and industrialization of economies, heavy industry can also have significant negative side effects: both local communities and workers frequently encounter health risks, heavy industries tend to produce byproducts that both pollute the air and water, and the industrial supply chain is often involved in other environmental justice issues from mining and transportation. Because of their intensity, heavy industries are also significant contributors to greenhouse gas emissions that cause climate change, and certain parts of the industries, especially high-heat processes used in metal working and cement production, are hard to decarbonize. Industrial activities such as mining also results in pollution consisting of heavy metals. Heavy metals are very damaging to the environment because they cannot be chemically degraded.

Decarbonization in the context of Just Transition

Just transition is a concept that emerged in the 1980s through efforts by U.S. trade unions to protect workers' rights and livelihoods as economies shift to sustainable production, primarily protecting workers affected by environmental regulations. Since then, it has evolved and gained global recognition, including having a place in the Paris Agreement in 2015. A just transition focuses on the connection between energy transition and equitable approaches to decarbonization that support broader development goals. A growing number of countries are incorporating just transition strategies to achieve ambitious climate goals, with 38% of 170 countries referring to just transition in their short-term climate plans as of 2022.
