Net Zero by 2050: Salvation or Economic Suicide?

The Intergovernmental Panel on Climate Change's Sixth Assessment Report (AR6) states that to limit global warming to 1.5°C above pre-industrial levels, global CO2 emissions must reach net zero around 2050. The report documents that current warming of 1.1°C has already increased the frequency and intensity of heatwaves, heavy precipitation, and droughts, causing widespread displacement and economic losses. It warns that every additional 0.5°C of warming increases risks to food security, water supply, and human health, and that delayed mitigation would make adaptation impossible in many regions.

The International Renewable Energy Agency's (IRENA) 2023 report shows that the global weighted average cost of electricity from utility-scale solar PV fell by 89% between 2010 and 2022, and onshore wind by 69%. In 2022, 86% of newly commissioned renewable capacity (187 GW) had lower costs than fossil fuel-based electricity. The report highlights that renewable energy investments create three times more jobs per million dollars than fossil fuels, and that accelerating the energy transition could add $32 trillion to global GDP by 2050 compared to a business-as-usual path.

Germany, the pioneer of renewable energy transition, has seen residential electricity prices rise to over €0.40 per kWh in 2023, the highest in the EU, while industrial prices are nearly double the global average. Despite spending over €200 billion on renewables since 2000, Germany's CO2 emissions have only fallen by about 35% from 1990 levels, and the country still relies on coal for about 30% of its electricity. Grid stability has required massive backup capacity, including reopening coal plants and importing nuclear power from rance, while the phase-out of nuclear and coal has led to social unrest and energy poverty for low-income households, with over 5 million Germans unable to pay energy bills in 2022.

The 2018-2019 Yellow Vest (gilets jaunes) movement in rance, sparked by a carbon tax increase on fuel, revealed deep social inequalities in climate policy. Research from the rench Economic Observatory (Observatoire français des conjonctures économiques, OCE) found that the carbon tax disproportionately burdened rural and low-income households, who spend a larger share of income on transport and heating. The protests led to policy reversals and a €10 billion in concessions. Economists note that similar carbon taxes in the EU's Emissions Trading System have raised household energy costs by 20-30% in 2022-2023, pushing many into energy poverty, and that the transition's costs are regressive without targeted compensation.
