Tackling climate change will be nearly impossible without advancements in climate tech. There is a consensus that we need a set of technologies to address the challenges of climate change. New solutions to decarbonize sectors like energy, heavy industry, food, mobility, and the built environment show promise that we might be able to reach net zero emissions by the middle of this century to mitigate the worst effects of global warming.
However, the first global stocktake of the Paris Agreement, presented at COP28 in Dubai last year, reaffirmed that we are off track with our decarbonization efforts to meet the 1.5°C target. Most of the technologies needed to meet our targets are not ready yet. According to the International Energy Agency (IEA), 35% of the emissions reductions needed by 2050 will come from technologies that are currently only under development or not yet at commercial scale.
While emissions reductions will be the main source of climate mitigation until 2050, we will also have to actively remove CO2 from the atmosphere. We will need carbon dioxide removal (CDR) to get to a true net zero, especially in industries with hard-to-abate emissions. But just like emissions reductions, CDR is not on the right track yet. A very recent study by a group of researchers from the Mercator Research Institute on Global Commons and Climate Change indicates that if countries do not adjust their policies, we will also see a large “CDR gap.” According to the study, CDR will increase by up to 1.9 billion tonnes of CO2 per year by 2050 if governments implement their current mitigation pledges. Depending on different IPCC scenarios, there will be a “CDR gap” in 2050 between 0.4bn – 5.5bn tonnes of CO2 removed per year.
