07 Apr Decarbonization: What is it, and why is it Important?
Decarbonisation stands at the forefront of the global agenda as nations, corporations, and individuals rally to combat climate change and its far-reaching consequences.
As a critical pathway towards the reduction or elimination of carbon emissions, it stands as a crucial step towards achieving the ambitious targets outlined in The Paris Agreement. However, despite growing awareness and high-profile commitments from industry giants like General Motors and PepsiCo, the world continues to grapple with escalating carbon emissions, exacerbating the greenhouse effect and accelerating global warming.
In this article, we will take a deep dive into the essence of decarbonisation, examining its significance, and underscoring the imperative for businesses to embrace this transformative journey towards a sustainable future.
What is Decarbonisation?
As atmospheric carbon dioxide levels hit unprecedented highs in 2021, the urgency of decarbonisation has never been more pronounced. Decarbonisation, at its core, is a strategic endeavour aimed at reducing human-induced carbon dioxide (CO2) emissions. Decarbonization fundamentally entails the reduction or elimination of carbon emissions from various sectors of human activity, primarily from industries, transportation, and energy generation.
It seeks to transition from reliance on fossil fuels, such as coal, oil, and natural gas, towards cleaner and more sustainable energy sources. By doing so, it aims to mitigate the adverse effects of climate change, safeguarding the environment and fostering a sustainable future for generations to come.
By embracing decarbonisation, societies can not only mitigate the adverse effects of climate change but also unlock a myriad of benefits spanning risk management, public health, value creation, and innovation.
The Urgency of Action: Why Decarbonise?
The urgency of taking action towards decarbonisation cannot be overstated. Not only does our reliance on fossil fuels pose a dire environmental threat, but it also presents a significant economic challenge. Consider the staggering costs associated with climate change. According to an IPCC report, global economic damages from warming in 2100 for 1.5°C is projected at $54. If we however fail to meet this mark, this figure could soar to $69 trillion.
But the toll is not merely financial; it’s also measured in human lives and livelihoods. Vulnerable populations, particularly those in impoverished regions, bear the brunt of climate-related disasters, facing heightened risks of floods, droughts, and heatwaves. The World Health Organization (WHO) predicts an additional 250,000 deaths annually between 2030 and 2050 due to heat stress and malnutrition by climate change, if we do not take decisive action. Furthermore, rising sea levels threaten to displace millions of people, while intensified rainfall events exacerbate water scarcity and ecosystem disruptions. Each half-degree increase in global temperatures brings with it profound consequences, from accelerated species extinction to systemic economic risks.
Pathways to Decarbonisation
Achieving decarbonisation demands a comprehensive approach that encompasses a wide array of sectors, each requiring tailored strategies and technological innovations. Here, we explore key sectors crucial to the decarbonisation journey and the transformative shifts required within them:
Industry
Industrial operations constitute a significant portion of global energy consumption, with activities such as mining, oil production, and chemical manufacturing heavily reliant on carbon-rich fossil fuels. To decarbonise industrial processes, a paradigm shift is imperative. This entails transitioning away from coal-centric methods towards sustainable alternatives like biomass, green hydrogen, and natural gas, alongside embracing electrification technologies. Additionally, innovations such as carbon capture and storage (CCS) offer promising avenues to curb emissions from industrial activities, contributing to a sustainable future.
Electricity and Heat Production
The generation of electricity and heat accounts for a substantial portion of global carbon dioxide emissions. Transitioning towards renewable energy sources, including solar and wind, is paramount to decarbonising this sector. Encouragingly, a significant proportion of global electricity generation already comes from renewable and nuclear energy sources. Electrification, coupled with enhanced energy efficiency measures, presents a promising approach to reducing the carbon footprint of lighting, appliances, and heating systems, thereby accelerating the shift towards a decarbonised energy landscape.
Transportation
The transportation sector is a major contributor to global carbon dioxide emissions, primarily from vehicles such as cars, buses, and trucks. To mitigate emissions from transportation, embracing alternative fuels and technologies is crucial. Electric vehicles (EVs), hydrogen fuel cell vehicles, and biofuels offer promising pathways towards reducing emissions in this sector. Furthermore, optimising efficiency and promoting sustainable commuting practices can further contribute to emissions reduction, fostering a more sustainable transportation ecosystem.
Agriculture
The agricultural sector accounts for a significant portion of global greenhouse gas emissions, primarily from methane and nitrous oxide emissions. Transitioning towards cleaner fuel alternatives for agricultural machinery and embracing regenerative agricultural practices are essential steps towards decarbonising agriculture. Moreover, leveraging agricultural land as carbon sinks through reforestation and sustainable land management practices can significantly contribute to carbon sequestration efforts, mitigating the sector’s overall carbon footprint.
Forestry and Land Use Change
Addressing emissions from forestry and land use change is critical in the decarbonisation journey. Land use changes, including deforestation for agricultural expansion and urban development, contribute significantly to global emissions. Protecting carbon-rich ecosystems and implementing sustainable land management practices are essential strategies to mitigate emissions from this sector, preventing further deforestation and degradation of vital carbon-absorbing regions.
Waste Management
Waste management practices are significant contributors to global methane and nitrous oxide emissions, exacerbating global warming. Emphasising waste reduction, reuse, and recycling, alongside implementing efficient waste management systems, is essential for mitigating emissions from this sector. Additionally, prioritising product design that promotes durability and recyclability can significantly reduce both consumption and production-based emissions, contributing to a circular economy and sustainable waste management practices.
