Cities play a fundamental role in reducing greenhouse gas emissions and advancing the 2030 Agenda for Sustainable Development. In this context, public authorities need tools to help in identifying the best set of available solutions for the urban environment. Here, we developed an approach to help decision makers in evaluating sustainable solutions, considering aspects such as emission rate, economic attractiveness, job creation, and local competitiveness in an intersectoral fashion. To rank the best solutions, we developed a new methodology that links integrated assessment models (IAMs) to the available solutions at the Innovation Observatory for Sustainable Cities (OICS) database and applied it to Brazil. Our results show that the solutions with the greatest impact were often related to new technologies, for example, renewable energy, which depends on institutional and financial arrangements that are beyond the administrative capacity of the vast majority of municipalities. Despite these limitations, Brazilian cities can act as regulators or provide financial incentives and advocacy to promote sustainable solutions in the urban environment.

    It is estimated that $1 trillion to $6 trillion per year (up to 2050) needs to be invested globally if the world is to stay below the 2°C global warming ceiling of the Paris Agreement and to meet its adaptation goals. Currently, investments stand at about $630 billion per year, way below the original target. And although great efforts have been made in the climate-finance area, more than 70% of the funds deployed have gone to one sector, renewable energy, followed by the transportat ...

    Energy markets have experienced significant disruptions since the outbreak of COVID-19. In late 2021, soaring natural gas prices triggered a new crisis, leading to risks of energy supply shortages worldwide and propelling the issue of energy security to the forefront. Africa will not be spared the repercussions of this crisis, which could further increase energy inequality, which is in turn linked to other forms of inequality. Indeed, in a context of persistent inflation, the lack o ...

    Why Green Finance Taxonomies? The increasing effort to mitigate climate change has caused more and more individuals, governments, and companies to shift away from traditional financial investments and activities, and towards more environmentally-friendly alternatives. However, until recently, there has been a lack of consensus on what green finance and its environmental impact is. Thus, green finance taxonomies are needed to provide classification systems that identify how environm ...
