“Time is up for waiting”: UN urges immediate climate action to avoid catastrophes

The UN has warned that time is running out to stop the climate crisis and that immediate and massive action is needed to avoid a catastrophic 3.1°C rise in global temperatures. The new report from the UN Environment Programme (UNEP) calls on countries to reduce emissions by 42% by 2030 and 57% by 2035, demanding political courage to abandon dependence on fossil fuels. Without these measures at the upcoming COP29 climate summit, the 1.5°C target could be unattainable.

The urgency of emissions cuts and the “decisive hour” for the climate

The United Nations Environment Programme (UNEP) has been clear in its latest report: reducing emissions is already a global emergency. According to the report, current commitments to reduce emissions by 2030 are insufficient, and even if they were met, warming would reach between 2.6 and 2.8 °C, a disastrous level for the planet. To keep the increase to 1.5 °C, Emissions must be reduced by 7.5% per year until 2035, which is equivalent to eliminating the emissions of the entire European Union for a decade each year.

The UNEP report emphasizes that the necessary technological and financial resources already exist, with proven sources such as solar and wind power capable of providing 27% of the necessary cuts. However, the problem lies in the lack of “political courage”, especially from the G20 countries, which are responsible for 77% of global emissions. Inger Andersen, head of UNEP, stresses that this effort requires an unprecedented shift towards clean energy, forest protection and electrification of industrial sectors. “The time for broken promises is over; immediate action is needed,” said Andersen.

Costs of inaction and the crucial role of world leaders

Lack of climate action has an imminent economic and human cost. Every fraction of an additional degree in global temperature contributes to extreme events such as intensified hurricanes, wildfires and heat waves. According to UN Secretary-General António Guterres, “We are playing with fire” as storms and extreme heat devastate communities around the worldGuterres also said that a fair transition to clean energy could be financed by taxes on fossil fuels, which would ease the burden of the crisis on less developed countries.

Unep estimates that the The annual investment needed to reduce net emissions to zero is $1-2 trillion, roughly 1% of the global economy., a cost that could be evenly distributed if rich countries financially support developing countries. At the next climate summit, COP29, world leaders are expected to define specific and ambitious commitments, especially regarding climate finance, emissions reductions and energy transition. For Harjeet Singh, of the Fossil Fuel Non-Proliferation Treaty Initiative, rich countries must assume their “fair share of responsibility” to achieve a sustainable future and avoid an irreversible climate crisis.

Renewables and forest protection: urgent and accessible solutions

The UNEP report stresses that a rapid expansion of renewable energy and the protection of forests would be two of the most effective and accessible measures to reduce emissions in the short term. Solar and wind energy, mature and low-cost technologies, could cover up to 27% of the cuts needed by 2030, thereby avoiding greater dependence on fossil fuels. Inger Andersen stressed that investing in renewables is not a risky decision, but a safe and economic investment in the current context, since these resources not only help reduce the climate impact, but also generate employment and improve energy security.

Halting deforestation, particularly in critical areas such as the Amazon and Central African forests, could also reduce emissions by 20%. This approach is key to preserving natural “carbon sinks,” which absorb large amounts of carbon dioxide, mitigating global warming.Forest conservation also helps protect biodiversity and water resources, which are essential benefits for the health of ecosystems and the communities that depend on them.

Geopolitical challenges and the road to COP29

The climate crisis demands global cooperation at a time of political tensions. Andersen acknowledged the current geopolitical difficulties – including conflicts in Ukraine and the Middle East and rivalry between powers – But he stressed that the environmental crisis is a priority where nations can find common ground.As an example, he mentioned the recent G20 meeting, where countries with opposing political positions managed to reach agreements on environmental policies.

With COP29 just around the corner, the summit promises to be a decisive point in defining world leaders' commitment to combating climate change. Negotiations are expected to focus on financing for developing countries and creating a stronger international framework for reducing emissions. "Inaction is no longer an option," Andersen warned, stressing that efforts towards a low-carbon future will not only save lives, but also pave the way for sustainable economic growth.
