It is highly important to attain innovations in activities by which energy is harnessed, in order to surpass the most important challenges that exist, before achieving zero emissions. And carbon dioxide emissions from human activities must reach nearly zero levels in several decades, in order to provide protecting against effects of climate change. Adopting such changes is certainly expected to happen once a lot of creativity and transformation is attempted by humans. This is mainly in context to some industrial sources of atmospheric carbon that lacks affordable emission-free substitutes.
More Insights into the Study Regarding Zero Carbon Dioxide Emissions
The above-described thought has been the result of a new paper published in Science from several team of experts led by University of California Irvine’s Steven Davis and Carnegie’s Ken Caldeira. According to the lead author Davis, the team wanted to closely study the barriers and opportunities associated with the most difficult-to-decolonize services. Some of the barriers have been briefly surmised in this study and include various facts and figures associated with air travel, freight shipping, and other sectors that could be causing maximum emissions.
For example, one barrier involves an increase in air travel and freight shipping which already contribute about 6 percent emissions. The second barrier consists of steel and cement manufacturing, which could release about 1.3 and 1.7 billion tons of carbon dioxide emissions into the atmosphere annually. These figures could grow as infrastructure demands increase, mainly in urbanized regions. And lastly, the third main barrier deals with the necessity of generating and transmitting electricity with almost 100 percent reliability, regardless of variations happening in energy sources such as wind and solar.
Thus, with these considerations in mind, it certainly would be difficult to reduce carbon emissions, thus calling out for new processes, systems, and innovations. Only then would be the long standing dream of reducing emissions would become true.
