Isabel Maria de Almeida e Castro (born 1954), is a former deputy in the Assembly of the Republic of Portugal, representing the Ecologist Party "The Greens".
In 2004, on the 30th anniversary of the Carnation Revolution that overthrew the Estado Novo dictatorship, she highlighted many of the environmental issues that Portugal still faced.
These included the bias towards development in coastal areas; the increased production of solid waste with low emphasis on recycling; the pollution of Portuguese rivers; desertification; the extinction of animal and plant species; erosion; increased air pollution and carbon dioxide emissions; and dependency on imported energy and lack of progress with renewable energy production.
[4] Castro has been very critical of the United Nations Climate Change Conferences, saying that they are "chronicles of imminent disaster" with a lack of commitment to action.
She has also been involved with the Iniciativa de Auditoria Cidadã à Divida Pública, the Portuguese branch of the International Citizen Debt Audit Network (ICAN).
