World on Climate Threshold: COP30, Carbon Tax, and Emissions Record
In the face of escalating climate concerns, the COP30 climate summit in Brazil has shed light on the necessity of immediate action. The International Monetary Fund (IMF), the Organisation for Economic Co-operation and Development (OECD), and the World Bank propose a carbon tax as a more effective method for reducing emissions over Emission Trading Systems (ETS). Meanwhile, the world's largest polluter, China, shows signs of emissions plateauing, and a push for removing carbon from the atmosphere is gaining momentum. However, a looming threat persists as the Global Carbon Project anticipates a record high in greenhouse gas emissions by 2025.
The COP30 Climate Summit
The COP30 summit, held from November 10 to 21 in Brazil, emphasizes the urgency to address climate issues by focusing on the reduction of greenhouse gas emissions, the transition from fossil fuels, and climate financing. As the event unfolds, the UN analysis reveals a potential shortfall in global emissions reduction, predicting only a 12% decrease by 2035.
The Carbon Tax Proposal
The IMF, OECD, and World Bank have endorsed a carbon tax as a more effective tool in combating climate change compared to the ETS. This proposal emerges from an analysis of 201 documents by these influential multilateral organizations. The efficiency of this tax is still a matter of debate among politicians and economists, with some advocating for cap-and-trade systems or a combination of both.
Emissions: A Mixed Picture
China, the world's highest emitter, has shown signs of stabilizing or even reducing its CO2 emissions over the past 18 months. Rapid deployment of solar and wind power generation in the country has helped keep energy sector emissions flat, even as electricity demand increases.
However, the Global Carbon Project reports that greenhouse gas emissions are on track to reach a record high by 2025. The report attributes this increase to rising coal, oil, and gas usage, even as emissions from deforestation decrease.
The Push for Carbon Removal
Johan Rockström of the Potsdam Institute for Climate Impact Research and a chief scientific advisor to the UN and the COP30 presidency, warns of the necessity of removing carbon from the atmosphere to avoid catastrophic climate tipping points. He suggests that even in the best-case scenario, the world will heat by about 1.7C.
Looking Forward
Despite the grim projections, there are glimmers of hope. Electric vehicles (EVs) show promise in long-term emissions reduction, surpassing gas-powered cars in total CO2 savings after about two years on the road. Meanwhile, some nations have submitted their Nationally Determined Contributions (NDCs) to the COP30, with 110 climate targets delivered, representing 71% of global greenhouse gas emissions.
However, the race against time continues, as the world teeters on the brink of overshooting the 1.5°C global warming limit set in the Paris Agreement. As the world continues to grapple with these challenges, the fight against climate change must rise above ideology, necessitating collective action from countries and corporations alike.
