Recently, Oxfam International reported that the urgent focus on announcing Net Zero Carbon Targets might be dangerously distracting from the crucial priority of reducing carbon emissions. Many nations such as New Zealand, UK, US, China and the European Union have set net-zero targets on greenhouse gas emissions to combat climate change. The report accentuates that mitigating emissions is not a suitable replacement for actually diminishing them.
Oxfam International, founded in 1995, is a collective of independent non-governmental organizations addressing a variety of global issues.
Understanding Net-Zero
Net-zero, synonymous with carbon neutrality, signifies a situation where a country’s emissions are counterbalanced by the absorption and removal of greenhouse gases from the atmosphere. It doesn’t necessarily imply that a nation would decrease its emissions to zero. That scenario, termed gross-zero, envisages a state with no emissions at all – a concept difficult to fathom.
One method by which carbon can be absorbed is through the creation of carbon sinks. If the absorption and removal surpass the actual emissions, a nation could even achieve negative emissions.
Carbon Sinks and Negative Emissions
Until recently, the Amazon rainforests, the largest tropical forests worldwide, acted as carbon sinks. However, due to significant deforestation, eastern parts of these forests have begun emitting CO2 instead of absorbing it. Interestingly, Bhutan boasts negative emissions as it absorbs more than it emits.
Examples of Countries With Net-Zero Targets
The European Union has conceived a plan, “Fit for 55”, aimed at delivering carbon neutrality. China has also pledged to become net-zero by 2060, restricting its emissions to peak no later than 2030. The International Energy Agency’s (IEA) has formulated its Net Zero Emissions (NZE) Roadmap, titled ‘Net Zero by 2050’.
Key Findings of the Oxfam International Report
The report highlights that to control the continuously soaring emissions of the energy sector, an area almost the size of the Amazon rainforest would be required. This represents a third of all worldwide farmland. If the climate change challenge is to be tackled solely by planting more trees, new forests spanning 1.6 billion hectares would be required to counterbalance the world’s surplus carbon emissions by 2050.
However, relying solely on land-based solutions could escalate food crises, potentially augmenting them by 80% by 2050. To restrict global warming below 1.5°C and prevent irreversible climate change, the global community needs to significantly reduce emissions by 45% from 2010 levels by 2030.
Analysis: ‘Net-Zero’ Versus Climate Change
The adoption of net-zero targets by governments and companies could inadvertently let the largest emitters off the hook from making substantial cuts to their own emissions. This reliance might also lead to an upsurge in land demand, potentially exacerbating hunger and fueling land inequality if not managed carefully.
Way Forward: Towards a Sustainable Climate Future
The path towards net-zero should reflect genuine and transformative climate action rather than greenwash. The emphasis should be on reducing carbon emissions immediately and adopting ‘food-first’ approaches in land-based climate solutions to achieve zero emissions without inducing hunger.
