I am a youth climate justice advocate born and raised in Brazil, and a Master in Public Policy candidate at the Harvard Kennedy School, studying disaster risk financing and climate policies in Latin America and the Caribbean. When I was 22, I founded the youth-led organization EmpoderaClima, where I still serve as the Director , to raise awareness of the need for women's empowerment in climate decision-making spaces, and advocate for girls' education and climate action. In my climate advocacy, I have engaged closely with UN Women, the UNFCCC and the New York Times through formal roles focused on youth leadership. My entry into public service ignited a wish to address the climate crisis in decision-making spaces through policy, and in recent years, I have worked with Brazilian politics and climate action at the British Mission in Rio de Janeiro, and with sustainable development at the United Nations Office of the Secretary-General's Envoy on Youth. I have been taking part in the global climate negotiations since COP21 in Paris, and I am a firm believer that more intersectionality and diversity in climate policy spaces can have an important impact on the outcomes of the negotiations.

Last fall I worked with dozens of Harvard undergraduates to organize Our Climate Change Stories (OCCS) and found the Harvard Climate Coalition. OCCS featured seven Harvard students to share their personal stories of environmental injustice, community resilience, and climate action in front of an audience of over 150 Harvard students, faculty, staff, and members of the local community. OCCS was the first time Harvard’s undergraduate environmental groups collaborated on any initiative, and as soon as we started organizing OCCS, student group leaders voiced their dreams to create a coalition to unite the environmental groups and strengthen our campus climate community. I served as a facilitator of the creation of the Harvard Climate Coalition, working with campus climate leaders to find shared values, shared goals, and a structure for our Coalition. The Coalition was founded in December and serves as the hub for undergraduate climate action, providing students with the resources and community they need to turn their climate action visions into reality. I currently serve as the Longevity Chair of the Coalition, which means I have a have a birds-eye view of the Coalition and act to ensure that this Coalition has a long life.

I have devoted my time and effort to tackling climate change by focusing on several key areas. Firstly, I've prioritized energy efficiency by implementing measures such as upgrading buildings with better insulation and energy-efficient appliances. I've also been active in promoting energy conservation in both communities and industries. Moreover, I've been a strong advocate for transitioning to renewable energy sources as well as investing in research for emerging technologies for energy storage. Additionally, I've championed sustainability by promoting eco-friendly practices such as sustainable agriculture and forest/river conservation. I've also been involved in initiatives to reduce waste and increase recycling efforts. Through these, I've aimed to raise awareness about the importance of sustainable living and the urgent need to address climate change. By taking action on multiple fronts, I believe we can create a more sustainable future for generations to come.
