Decarbonization is crucial for reaching the goal of net zero emissions, as outlined in The Paris Agreement. Despite efforts, global carbon dioxide levels hit record highs in 2021, showing the urgency for action. The rate of carbon emissions is surpassing the Earth’s ability to absorb them, worsening the greenhouse effect and speeding up global warming.
Currently, big companies like General Motors and PepsiCo are taking the lead in decarbonization efforts. However, turning these promises into real progress needs ongoing dedication and teamwork from everyone involved. Decarbonization involves many different aspects and requires participation from various groups, including governments, businesses, and individuals. Only by working together can we effectively reduce the worst effects of climate change.
This guide gives you an overview of decarbonization, with examples and why it’s crucial for businesses.
What is decarbonization?
Decarbonization simply means reducing the amount of carbon dioxide (CO2) we release into the air. It’s like turning down the heat on our planet! We do this by switching to cleaner energy sources, like solar, wind, and geothermal power, instead of relying on fossil fuels like coal and oil.
To limit global warming to 1.5°C above pre-industrial levels, many countries aim to achieve net zero greenhouse gas (GHG) emissions by 2050. Net zero means that the amount of GHG emissions released into the atmosphere is balanced by the amount removed. This requires rapid decarbonization efforts.
Decarbonization involves drastically reducing GHG emissions from human activities as a first step. For emissions that can’t be eliminated, measures must be taken to remove them from the atmosphere.
The term “decarbonization” encompasses all GHG emissions, including carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, nitrogen trifluoride, perfluorocarbons, and hydrofluorocarbons. The potency of these GHGs is measured by their global warming potential (GWP), expressed in CO2 equivalents.
How Does Decarbonisation Work?
Decarbonization works by reducing or eliminating the release of greenhouse gas (GHG) emissions into the atmosphere, primarily through transitioning away from fossil fuel-based energy sources and adopting cleaner, renewable alternatives. Overall, decarbonization involves a comprehensive approach that encompasses technological advancements, policy interventions, and behavioral changes to reduce GHG emissions and mitigate climate change.
Strategies for implementing decarbonisation
Organizations formulate their decarbonization strategies based on factors such as business feasibility, existing opportunities, and practical implementation methods.
- Enhance Operational Efficiency: Improving operational efficiency is key to reducing energy waste and lowering emissions. Utilizing performance monitoring software can pinpoint energy use issues and identify areas for improvement. Upgrading equipment to energy-efficient technology when feasible is also crucial.
- Electrification: Transitioning from fossil fuel-based technologies to those powered by electricity can significantly reduce emissions. This includes adopting electric heating, cooling, transportation, and manufacturing processes.
- Transition to Low-carbon Energy Sources: Switching to low-carbon or renewable energy sources is a tangible step organizations can take. This involves installing renewable energy technologies like solar panels and procuring renewable energy from providers offering wind, solar, hydropower, and biomass options.
- Addressing Upstream and Downstream Emissions: Collaborating with suppliers to reduce emissions throughout the supply chain can accelerate decarbonization efforts.
- Managing Residual Emissions: Since eliminating all greenhouse gas emissions may be challenging, organizations must deal with residual emissions. Technologies like Carbon Capture and Storage (CCS) capture emissions before release, storing them securely underground. Direct Air Capture (DAC) technology removes carbon dioxide from the air using specialized substances.
By implementing these strategies, organizations can effectively reduce their carbon footprint and contribute to a more sustainable future.
Role of Businesses in Achieving Global Decarbonization
