DUBAI, United Arab Emirates — Why promise net zero emissions when you can go even lower, such as negative emissions?

As countries at the COP28 climate talks are wrangling over ways to lower their greenhouse gas emissions, a Danish-led group of countries has decided to set the ultimate goal: to remove more carbon dioxide, the main source of global warming, from the atmosphere than they emit.

The Group of Negative Emitters was launched Sunday in Dubai by Denmark, Finland and Panama, and aims to reach that goal by slashing emissions, protecting and expanding forests, and investing in new technologies. Panama has already reached the goal with its vast forests that act as a huge carbon sink. Finland and Denmark hope to achieve this by 2035 and 2045, respectively.

“It’s a huge challenge to become carbon neutral and then carbon negative and we are not yet there,” cautioned Kai Mykkänen, Finland’s environment minister, “but we are really targeting this.”

For the rich Nordic country, the strategy is threefold. It will cut emissions, especially in the energy sector, expand forests, and invest in carbon capture and removal technology that traps planet-warming emissions from reaching the atmosphere and then transport it to where it can be permanently stored underground.

Many experts say the technology to capture carbon and store works but is expensive. It's still in the early days of deployment, so not available at scale. There are about 40 large carbon capture projects in operation around the
