Climate change has been described as the most defining challenge of our time. It has been identified as one of the main global challenges that is affecting both developed and developing countries in their efforts towards realization of the Sustainable Development agenda. Climate change is an undesirable phenomenon that affects realization of the Sustainable Development agenda across the world by affecting the sustainability of the planet’s ecosystems, the stability of the global economy and the future of humankind. The consequences of climate change such as intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity are being witnessed across the world affecting the realization of Sustainable Development.
It has been argued that if left unchecked, climate change will undo a lot of the development progress made over the past years and will also provoke mass migrations that will lead to instability and wars. As a result of the foregoing concerns, it has been asserted that the climate time-bomb is ticking6. In addition, it has been argued that the world needs a greater climate ambition. There is need to massively fast-track climate efforts by every country and every sector and on every timeframe. Sustainable Development Goal 13 calls upon all countries to take urgent actions towards combating climate change and its impacts.
Indeed, with the world facing an urgent climate crisis, the need for sustainable solutions has never been greater. As a result, it has been observed that one of the most ambitious targets that countries and organisations have set is achieving net-zero emissions. According to the Intergovernmental Panel on Climate Change (IPCC) net zero emissions are achieved when anthropogenic carbon dioxide emissions are balanced globally by anthropogenic carbon dioxide removals over a specified period. Further, it has been pointed out that the term net zero refers to the target of reducing the greenhouse gas emissions that cause global warming to zero by balancing the amount released into the atmosphere with the amount removed and stored by carbon sinks.
Net zero carbon dioxide emissions can also be referred to as carbon neutrality. According to the Organisation for Economic Cooperation and Development (OECD), net-zero carbon dioxide emissions is also sometimes referred to as carbon neutrality and at a global scale, the two terms are equivalent. However, OECD points out that at regional, national and sub-national level, the term net-zero carbon dioxide emissions is generally applied to emissions and removals under direct responsibility of the reporting entity, whereas the term carbon neutrality generally includes emissions and removals within and beyond direct responsibility of the reporting entity.
The term net-zero emissions is understood to cover all anthropogenic greenhouse gas emissions covered by the United Nations Framework Convention on Climate Change (UNFCCC). These gases include carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons. It has been pointed out that achieving net zero emissions or carbon neutrality requires striking a balance between the amount of emissions put into the atmosphere with the amount taken out.
Achieving net zero requires removing carbon emissions from the atmosphere equal to the amount produced by human activities through various measures which include carbon capture and storage, afforestation, and the use of renewable energy sources. Further, it has been observed that net-zero emissions will be achieved when all emissions released by human activities are counterbalanced by removing carbon from the atmosphere in a process known as carbon removal. Achieving net zero requires a two-pronged approach. On the first part, it requires human-caused emissions (such as those from fossil-fueled vehicles and factories) to be reduced as close to zero as possible.
Secondly, it requires that any remaining emissions be balanced with an equivalent amount of carbon removal, which can happen through natural approaches like restoring forests or through technologies like direct air capture and storage which scrubs carbon directly from the atmosphere. It has been argued that the goal of achieving net zero carbon emissions has become a central paradigm in global climate policy, and increasingly drives both analysis and action. In addition, it has been pointed out that achieving a net zero future remains the only way to stop a rise in global temperatures and presents many opportunities for development, economic diversification, and growth.
Achieving net zero emissions has numerous benefits for both nature and humanity. It has been correctly pointed out that investing in nature-based solutions, transitioning to sustainable practices and clean energy sources, and reducing carbon emissions can help alleviate the negative effects of climatic emergencies, including higher temperatures and sea levels, more extreme weather events, and limited access to food and water. In addition, it has been argued that reducing our carbon footprint also creates economic opportunities by developing new industries and jobs in various sectors such as energy, transport, and agriculture.
Additionally, adopting nature-based solutions and reducing the reliance on fossil fuels can contribute to better public health outcomes and improved environmental justice. It has also been argued that achieving net zero can foster a healthy, resilient, zero carbon recovery that prevents future threats, creates decent jobs, and unlocks inclusive, sustainable growth. It is therefore necessary to achieve net zero in order to effectively combat climate change and realize a sustainable future.
