I was born in Lisbon, Portugal. I am an environmental modeller working on climate and air quality policy, at RFF-CMCC EIEE in MIlan, Italy. I am an IPCC AR6 contributig author and was a consultant for the World Bank. I am interested in climate change, integrated assessment approaches, environmental statistics, energy policy, environmental economics, and air pollution. I like sunny days and skate bowls. I have two amazing kids: one ninja turtle and a jedi baby girl. We all live together with the amazing dad 'Tony Stark', whom we are trying to convince to adopt an Hamster.
Future socioeconomic developments and climate policies will play a role in air quality improvement. We compute new global annual air quality indices to provide insights into future global and regional air quality, allowing for the evaluation of climate policies. We project the future air pollution concentrations for 5 socioeconomic pathways and a broad range of climate radiative forcing targets, using a transport chemistry emulator and the emission database produced for the 6th IPCC assessment report. Our findings show that climate policies are very relevant in reducing air pollution exposure by mid-century and will have a stronger effect on the pollution reduction timing, while socioeconomic developments will have a greater impact on the absolute pollution level. A 1.5C policy target may prevent all regions from exceeding the annual average limit for all pollutants, except PM2.5. We emphasize the importance of considering exposure air quality indices rather than a population-weighted average index.
Air pollution (AP) is considered the main environmental problem by the World Health Organization (WHO). Outdoor AP is responsible for 3.3 million premature deaths yearly worldwide. With the continuous burning of fossil fuels and the increasing number of population living in cities, where polluting intense activities are very concentrated, this number is bound to increase if no oriented or integrated policy is in place. Global scale IAMs typically minimize the cost of climate policies, or national/regional energy strategies. Often this framework neglects the benefits that leak from the climate goals to other environmental issues. In this paper we propose a framework that internalizes the air pollution and the climate change impacts in order to inform on optimal cost-benefit multi-objective strategies. We set out to quantify the AP and CC impacts that can be avoided using optimal CBA policy. We investigate the regional heterogeneity of the impacts and provide insights about the robustness of CBA.
Integrated assessment models which include endogenous description of learning-by-researching dynamics allow the study of the influence of R&D investments on the cost of technologies. This is especially important in the context of climate change, due to the potential reductions on the cost of future green technologies that will allow the decarbonization of the energy system. Understanding the size of such investment, and its distribution across countries and technologies is a key insight to inform policy makers. This work will provide a space for knowledge sharing from different IAMs in order to improve the model representation of technical change. It will combine knowledge form econometric studies with the modelling of future technical change.
In the Glasgow COP26, several major emitters have announced new climate neutrality commitments. Others revised their nationally determined contributions (NDC). The climate, energy, and economic repercussion of these revised pledges is still unclear. Here, using a detailed-process integrated assessment model (WITCH), we analyze the impact of the Glasgow net-zero commitments and compare it to scenarios consistent with the Paris' agreement. We find that—if fully implemented—the Glasgow strategies would help close the gap to 2C , covering more than 80% of the world’s needed emission reductions by 2070. The pledged commitments would exceed 1.5°C, with a temperature increase (50% likelihood) of 1.6C- 1.8C by the end of the century. We find that the Glasgow net-zero pledges would require substantial increases in investment in electric transportation and power generation in all major economies. Compared to a scenario with uniform carbon taxation, Glasgow differentiated pledges’ do not significantly increase global policy costs, are more fair, and save more lives by promoting cleaner air. However, they delay coal phase-out and increase the need for negative emission technologies.
