Minister of Environment and Energy
Castro was Minister of Environment and Energy during two periods during the administrations of José María Figueres Olsen (1994–1998) and Laura Chinchilla Miranda (2010-2014).

During his first term, as Minister of Environment, Energy and Mines, he led the promulgation of the Organic Law of the Environment that transformed the ministry of MIRENEM to MINAE, other important laws approved are the forest law, the reform of Article 50 of the Political Constitution to include the right to a healthy environment as a constitutional guarantee and the ratification of global conventions on biodiversity and climate change. Costa Rica led, together with Brazil and other member countries of the group called G77 + China, to include the mechanism for clean development in the Kyoto Protocol, which promoted the transfer of resources from developed countries to others. The main achievement was to consolidate the payment of forest services. This mechanism based on a tax on fossil fuels has allowed Costa Rica to go from an 8% annual rate of deforestation (one of the highest in the world), to grow again in its forest cover in net terms. The country went from 21% of the territory with forest cover in the early 80s to 52.3% by 2013.

Another source of income was sales of  bonds. Costa Rica and Norway made the first global transaction, processing 200,000 tons of  for $2 million.

The use of lead in fuels was eliminated, according to data from the Children's Hospital, which damaged young children, and it was found that by 1997, the blood lead level of Costa Rican children had dropped to levels below the World Organization health. The reduction of the sulfur content in diesel was initiated and the Central American standard of 500 parts per million was adopted.

On 1 August 2011, Castro was appointed for a second term as Minister of Environment and Energy. On his first day in office, Castro issued a moratorium on oil exploration for the following three years. During his tenure he moved for a closure of zoos, and to keep animals uncaged, promoting more bioparks and recovery shelters.

In his role, as well as in other professional activities, Castro has promoted the payment of environmental services in Costa Rica; he and made the first post Kyoto Protocol CO2 transaction in the world. He was negotiator of the conversions of debt of Spain and Canada with Costa Rica and he advised several other countries in their respective negotiations.

Under his management, reforms were pushed to move the telecommunications sector to the Ministry of Science and Technology and to expand MINAE's responsibility for blue policies. The Vice Ministry of Waters and Oceans was established and the expansion of the responsibilities of MINAE in oceans was promoted to all non-commercial biodiversity. Marine protected areas expanded and forest cover growth continued to 54% by the end of 2014. the Montreal Protocol recognized Costa Rica and the Ministry of Environment under Castro for protecting the Ozone layer and being the first country in its region to eliminate the use of methyl bromide for roses, strawberries and flowers.

During this time, he was widely criticized for defending the construction of a $1.500 million refinery for the Costa Rican National Oil Refinery Company (RECOPE) together with the Chinese contractor CNPCI. This project was suspended by the General Comptroller of the Republic due to inconsistencies in the rentability and feasibility studies (developed during the previous government). The developments provoked the exit of the at the time president of the Costa Rican National Oil Refinery (RECOPE) Jorge Villalobos. On the other hand, Castro requested a complete set of studies from the Costa Rican public universities to ensure transparency and thorough review of the proposal.

Minister of Foreign Affairs
On 2 March 2010, president-elect Laura Chinchilla informed the media that Castro would serve as Minister of Foreign Affairs and Worship from 8 May 2010 (inauguration day). He remained in that position until 1 August 2011. He served in that position from inauguration day (8 May), replacing Bruno Stagno Ugarte. He was replaced in this position on 1 August 2011 by Enrique Castillo, former ambassador to the Organization of American States. This change happened during criticisms of his work handling the conflict of land dispute with Nicaragua by initially approving the work of the Nicaraguan government.  For this issue were Castro lacked experience for handling the situation.

During his term, embassies were opened and official visits were made to Qatar and India. Diplomatic representations were reopened in countries such as Bolivia, Jamaica and Paraguay that had ceased operations. The strategy for the defense of Costa Rican sovereignty was led as a peaceful and unarmed one, using only the instruments of international law such as the OAS, the International Court of Justice and the United Nations Security Council. As consecutive steps and in elevation.

Castro was summoned by the Legislative Fraction of the Citizens' Action Party (Costa Rica), which reproached him for allegedly making appointments in the foreign service based on political criteria and not on professional suitability. The then Chancellor held accounts for more than four hours in the Legislative Assembly, where he clarified and answered all the questions raised by the legislators of all the political fractions represented. The executive summary of this appearance can be consulted at the following link: and the complete record "ACTA No. 36" of Thursday, June 30, 2011. On December 19, 2011, the Attorney General's Office forwarded the AEP-AR-009-2011 report to the Ministry of Foreign Affairs, stating there were no irregularities in the professional appointments during his tenure. 
Castro began negotiations for a concordat with the Vatican. This was strongly criticized by observers who contended that it was a low priority. The previous concordat, which was abrogated during the nineteenth century, was signed in 1852. Thus, for the most part of its republican history, Costa Rica had not had a need of such a treaty with the Vatican. Critics pointed out that granting favourable treatment to the Catholic Church is inherently unfair and anti-democratic, given the large minority presence of other Christian denominations in Costa Rica. Others stated that the committee representing Costa Rica in the Vatican negotiations included Hugo Barrantes, a Costa Rican bishop. It was argued that Barrantes' allegiance would lean towards the Vatican, and not the Costa Rican government, raising doubts about Castro's leadership concerning Costa Rica's foreign affairs.

Military invasion by the Nicaraguan Army to Calero Island 
On October 21, 2010, the Nicaraguan Army invaded the Costa Rican territory of Isla Calero, an islet located in the north-eastern end of the country, initiating a new chapter of the conflict between Costa Rica and Nicaragua. Castro's leadership at the head of the conflict has been defended and criticized. According to some critics, the policy of appeasement followed by Castro Salazar provoked an aggressive behaviour of the president of Nicaragua Daniel Ortega, who ordered to militarily take the territory in dispute. Castro has repeatedly responded to these criticisms in various national media. Under the direction of Foreign Minister Castro, a team of specialists in international law was formed, denouncing the invasion of Nicaragua before the International Court of Justice based in The Hague, obtaining a diplomatic victory in November 2013  when this court issued precautionary measures against Nicaragua, ordering the departure of civilians and soldiers who were illegally occupying the area within a period of no more than two weeks.
