Intervention aaires: In addition to the main considerations and elements mentioned above, countries may consider considering the eight intervention aaires in order to guide their projects aimed at achieving a low-carbon economy. An intervention arena is an entry point to take action to change the course of events in order to achieve a low-carbon, climate-resilient economy by 2050. Arenas are (1) technologies and infrastructure, (2) financing, 3) markets, (4) policies, (5) institutions, (6) governance and engagement, (7) knowledge and information, and (8) practices and logics. Knowledge and information consist of interventions that generate, share or disseminate information to improve knowledge and know-how, in order to support accelerated and scalable implementation of decarbonized and climate-resistant development. These interventions include research and analysis, measurement and evaluation, learning partnerships, and training and capacity building of local populations and institutions. Practices and mentalities consist of actions to influence individual or private practices, decisions and behaviours, using social marketing tools and techniques and other areas, and often involve a change in mentality and an individual appreciation of opportunities and benefits, while recognizing the power of social links and relationships in establishing and strengthening norms and practices. While the list is not exhaustive, these arenas can be the main drivers of the transformation needed to achieve the goals of Vision 2050. Areas of intervention could guide countries in developing long-term strategies by providing possible entry points to address capacity gaps and key sectors that fuel emissions. The main regulatory advantage of a market-based approach is that it can achieve a given emission target at a lower social cost than a more stringent regulatory approach, as it is originally used to determine how to reduce emissions. In other words, market-based approaches leave the pollution reduction method to the issuer. As a result, issuers are encouraged to find the most cost-effective way to meet regulatory requirements.
