In order to achieve net zero emissions, it is necessary to accelerate the energy transition by embracing clean and green sources of energy such as renewable energy. The energy sector has been identified as a major contributor to climate change. For example, the extraction and burning of fossil fuels which are the major source of global energy supply has serious environmental consequences including climate change. It has been pointed out that when fossil fuels are burned, the stored carbon and other greenhouse gases are released into the atmosphere.
An excess buildup of greenhouse gases in the atmosphere as a result of burning of fossil fuels has resulted in dramatic changes to Earth’s climate— a trend that will worsen as more fossil fuels are burned. It has been observed that fossil fuels including coal, oil and natural gas are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions.
According to the International Energy Agency (IEA), as the major source of global emissions, the energy sector holds the key to responding to climate change. Achieving net zero therefore demands transitioning from fossil fuels to clean sources of energy such as renewable energy. IEA points out that achieving net zero emissions by 2050 will require nothing short of the complete transformation of the global energy system towards renewable sources of energy.
These sources of energy which include wind and solar are vital in achieving net zero since they emit little to no greenhouse gases. Further, these sources of energy are readily available and in most cases cheaper than coal, oil or gas. For example, it has been pointed out that Africa has an abundance of renewable energy (including wind, solar, hydro, bioenergy, ocean tidal waves, geothermal and other renewables) which can be vital in confronting climate change if well harnessed.
According to the African Union, the availability of abundant renewable energy resources on the continent such as hydropower, solar, wind, geothermal and bio-energy can transform Africa’s energy sector to modern and sustainable energy through both grid and off-grid systems and contribute to the fight against climate change. It is therefore necessary for Africa and the rest of the world to embrace renewable sources of energy in order to achieve net zero emissions. Further, it is important to embrace nature based solutions towards climate change.
Nature-based Solutions have been defined as actions to protect, sustainably manage and restore natural or modified ecosystems, which address societal challenges such as climate change, food and water security and natural disasters effectively and adaptively, while simultaneously providing human well-being and biodiversity benefits. They adopt the use of ecosystems and their services towards addressing societal challenges such as climate change. It has been asserted that nature based solutions have significant yet underutilized potential to address global threats including climate change, loss of biodiversity, food and water security, human health and natural disasters.
It has further been argued that nature based solutions are key to many countries’ and companies’ plans to achieve net-zero in the coming decades. For example, nature based solutions play a crucial role in achieving net-zero emissions by sequestering carbon and mitigating the effects of climate change. One key nature based solution that is vital in achieving net zero is regrowing natural forests, which can help to sequester and store carbon dioxide in their biomass. It has been observed that this approach involves restoring degraded or deforested areas with native species, increasing biodiversity, improving soil health, and enhancing the community’s resilience to climate change.
Further, embracing other nature based solutions such as the sustainable management of ecosystems, improving soil health, and using agroforestry practices, can help to sequester carbon, protect biodiversity, and improve the resilience of communities in the face of climate change. It has been pointed out that projects that embrace nature based solutions help to generate carbon credits that provide an income stream for local communities, incentivise environmental protection, provide an opportunity for investors, and help organisations and governments reach net zero. It is thus essential to embrace nature based solutions in order to achieve net zero emissions.
Achieving net zero emissions also requires implementing and fostering effective utilization of carbon markets. It has been observed that by purchasing permits or credits generated from emissions-reduction projects, emitting companies can unlock funding for the net-zero transition through carbon markets.
According to OECD, international carbon markets could potentially help countries enhance the ambition of their climate commitments and achieve their net-zero targets with greater economic efficiency, complementing domestic emission reduction efforts while providing other sustainable development co-benefits. In particular, international carbon markets could be useful for countries that are not able to achieve net-zero emissions through domestic mitigation actions alone.
Carbon markets are increasingly being seen as an essential part of efforts to reach net zero emissions by around 2050. It is therefore necessary to effectively utilize carbon markets in order to achieve net zero emissions. It is also imperative for all countries to promote low carbon development strategies across all sectors.
The concept of low carbon development which is also expressed using the term Low-Emission Development Strategies (LEDS) also known as low-carbon development strategies, or low-carbon growth plans refers to forward-looking national economic development plans or strategies that encompass low-emission and/or climateresilient economic growth. Low carbon development has also been defined as forwardlooking, climate-friendly growth strategies that can highlight a country’s priority actions for climate mitigation and adaptation, and a country’s role in the global effort against climate change.
The idea of low-carbon development aims to achieve the goals of reducing greenhouse gas emissions, exploiting low-carbon energy, and ensuring economic growth. Low carbon development strategies can help achieve net zero by reducing greenhouse gas emissions. It has been pointed out that reducing emissions at the source is the most effective way to achieve net zero.
It is therefore necessary for countries to embrace low carbon development strategies such as embracing renewable sources of energy including solar, wind and hydropower, adopting climate smart agricultural techniques, fostering sustainable cities, transport and infrastructure and adoption of sustainable waste management techniques in order to achieve net zero.
Further, in order to achieve net zero, it is crucial to invest in carbon removal technologies. It has been suggested that the deployment of greenhouse gas removal technologies can help to achieve net zero across an economy. For example, technologies like Direct Air Capture and Storage (DACS) can help achieve net zero by scrubbing carbon directly from the atmosphere. However, it has also been noted that the technologies in question, which include DACS and Bioenergy with Carbon Capture and Storage (BECCS), are not yet proven at scale, can be expensive and energy-intensive, and have their own unwanted negative impacts. It is therefore necessary to embrace technology with caution and give priority to abating domestic emissions as the primary way to bring emissions to net zero.
Finally, it has correctly been pointed out that in addition to governments, other entities including organisations, cities, and regions have a role to play in achieving net zero. It has been argued that businesses and organizations are vital in achieving net zero since the private sector development is the anchor that facilitates the knowledge, skills and infrastructure needed for sustainable practices within developing economies.
It has been correctly observed that many companies rely heavily on fossil fuels for their energy needs, and the transition to clean energy may require significant changes to their supply chains and business models. However, there are also significant opportunities for businesses that embrace the transition to net zero such as new markets, reduced regulatory risks and more reliable energy. It is therefore necessary for organizations to play their role towards achieving net zero.
Further, it has been pointed out that cities have a crucial role to play in achieving net zero since more than half of the global population live in cities, consuming 78% of the world’s primary energy and generating more than 70% of global carbon emissions. It is therefore necessary to catalyze urban decarbonization and resilience by improving energy efficiency, enhancing clean electrification and promoting resource circularity solutions. The foregoing among other measures are vital in achieving net zero emissions.
