New Study Shows Carbon Removal Plans Fall Short of Paris Agreement Targets

A groundbreaking study conducted by the University of East Anglia (UEA) has revealed a significant gap between current global carbon removal plans and what is required to meet the Paris Agreement's target of limiting global warming to 1.5°C. Published in Nature, the research indicates that existing plans could fall short by up to 3.2 billion tons of carbon dioxide (CO2) by 2050, a disparity that has dire implications for our ability to avoid the worst effects of global warming.

This study, the first to focus specifically on carbon removal gaps, builds upon previous measurements by the United Nations Environment Programme (UNEP) to assess the "emissions gap" between national climate protection plans and what's actually needed. The potential consequences of inaction include intensifying heatwaves, floods, droughts, melting ice, and rising sea levels.

Lead author Dr. William Lamb of the MCC Applied Sustainability Science working group emphasized the urgency of reducing emissions across all sectors. "Without a rapid reduction in emissions towards zero, across all sectors, the 1.5°C limit will not be met under any circumstances," he said.

The research highlights the need for an ambitious approach that goes beyond current practices, urging more robust efforts in cutting emissions, scaling renewable energy, and curbing deforestation. Moreover, novel carbon removal technologies, such as advanced air filter systems and enhanced rock weathering, should be scaled up. Currently, these novel methods remove only 0.002 billion tons of CO2 annually, compared to the 3 billion tons removed through conventional means.

Dr. Naomi Vaughan, co-author and member of the Tyndall Centre for Climate Change Research at UEA, stressed the importance of expanding carbon dioxide removal methods while simultaneously achieving deep emission reductions. Despite nations setting carbon removal targets, the expected increases in removal will still fall significantly short of the target. By 2050, these targets would increase carbon removal by just 1.9 billion tons, far below the 5.1 billion tons required to meet the 1.5°C target.

While the gap may seem insurmountable, there is still hope. The Intergovernmental Panel on Climate Change (IPCC) presents an alternative scenario where global governments collectively reduce energy demand through "politically initiated behavior." In this scenario, carbon removal could increase by 2.5 billion tons by 2050, narrowing the gap to 400 million tons.

In conclusion, the study serves as a call to action for global cooperation and more aggressive climate policies. Closing the carbon removal gap will require a shift from self-interest to a unified global approach, along with increased awareness, ambition, and action from nations worldwide.
