In a new study published in the journal Environmental Science and Ecotechnology, researchers from the Chinese Academy of Sciences (Guiyang), revealed a new model for the accurate evaluation of carbon neutrality capacity. The Carbon Neutrality Capacity Index (CNCI) model evaluates the contributions from various carbon sinks, providing important data for climate change policy development and emission reduction strategies.
The study used a variety of advanced analytical methods to create the CNCI model, with a key innovation being the inclusion of carbonate and silicate rock chemical weathering as carbon sinks, an area often overlooked in carbon neutrality assessments. In addition to this, the model also examines the vegetation ecosystem as a carbon sink.
The results show that Guizhou has a CNCI of 57%, higher than the Chinese average (11.88%) and the global average (27.14%). In addition, regions within Guizhou, such as Libo and Pingtang, show surpluses, where CNCIs are as high as 643% and 581%, respectively.
These results highlight the region’s potential to make a significant contribution to China’s carbon neutrality goal. The study concludes by emphasizing the critical role of rock weathering carbon sinks in assessing CNC in terrestrial ecosystems. It also proposes the CNCI model as an efficient and applicable tool for the comprehensive and systematic analysis of carbon neutrality, at the national and global levels.
In the long term, the findings of this study could play an important role in accelerating progress towards global carbon neutrality, a goal that is crucial in tackling climate change. The researchers hope that the findings of this study will provide important insights for scientists, policy makers, and climate activists around the world.
