Traceability of Technologies for Positive Climate Assessment: A Prospective Patent Study from the Year 1970 to 2022

Abstract

In this article, we present a study carried out through a qualitative-quantitative methodology of the exploratory-descriptive objective to investigate technologies that have obtained patents and contribute to the areas of architecture and urbanism, as well as information systems enhance the verification of the situation environmental and urban climate. In the investigation of these patents, we used a methodology divided into three stages: 1st – “Comprehensiveness”, 2nd – “Specification”, and 3rd – “Immersion” to identify the technologies described above and for the evaluation of the “positive climate” in urban areas, which are related to the reduction of environmental impacts as well as the reduction of CO2 levels. The analyses resulted in a universe of 38,413 patents that were divided by year. From the results of the patent mapping, we observed the advantages in the areas of technology, sustainability and energy obtained by countries such as China, USA, Europe and India. We obtained two units of patents granted, directly related to the theme of “climate positive”, however, none focused on zero carbon emission measures, positive energy balance, environmental performance or clean energy strategies. Thus, there was a need to encourage vigorously the development of more and better tools to achieve the goal of a “positive climate”.
