The Nicaragua office of Central American full-service law firm Arias offers a practice focused on energy, project development, and ESG. A key contact is Rodrigo Ibarra, who provides particular expertise in the energy transition and environmental law. 

The firm has experience advising a wide array of clients on their green projects, including investment management firms, agribusinesses, and sustainability-focused non-profit organisations. The firm’s work for such types of client includes advising on legal mechanisms for the development of renewable energy projects, the financing of sustainable resource extraction, and the structure of innovatively financed reforestation projects. 

With Nicaragua’s recent establishment of a National Committee for the Mitigation of Greenhouse Gas Emissions and a National Climate Change Policy, the firm has been active in publishing legal updates on emerging implications for environmental law, energy, and compliance. Alongside thought leadership on these broad legal developments, the firm has recently published sector-specific updates concerning tax incentives for renewable energy projects, electric mobility, reforestation and forest conservation, and ozone and single-use plastic regulation. Following the vision that they must not just inform clients but also educate legal staff, the team is also trained on these topics.

To complement the firm’s active commitment to pro bono work, the staff volunteered for soil and water conservation works during World Environment Day, assisting the construction of dams at the Montibelli Private Wildlife Reserve in order to reduce the risk of flooding.

DLA Piper


In Colombia, full-service law firm DLA Piper Martinez Beltrán has launched a dedicated environmental law and sustainable development practice, seeking to complement its demonstrable expertise in the energy transition by expanding its offering across climate change, sustainability, and ESG. 

José Miguel Mendoza, who co-leads DLA Piper’s regional ESG practice, advised renewable energy systems provider First Solar on the structuring and negotiating of an agreement to certify its products and begin operations in Colombia. The matter is crucial in expanding the renewable expertise available in the country, helping transition Colombia toward non-conventional energy. 

For energy construction group Powerchina, the firm is assisting on the permitting procedure, regulatory compliance, and execution of contracts for the development of the client’s 80 MW and 50 MW solar park projects. The firm also assisted the green transition of power generator Proelectrica, advising on the regulatory procedures necessary for grid interconnection within the structuring of the client’s 200 MW solar project. 

In a pioneering matter which supports a major Colombian electric utility in the provision of low-carbon electricity, Lucas Arboleda is acting for Air-e regarding the structuring and negotiating of an agreement with EDF Renewables for the co-development of wind-power projects, as will provide clean electricity to Air-e’s clients.  

Head of the firm’s environment and sustainable development practice Camila del Villar is advising Shell on the tax and legal structuring of its purchase of carbon offsets, consequentially supporting the financing of local forestry-based emissions removal projects.  

In a pro bono highlight for the Grantham Research Institute on Climate Change, the firm collaborated with DLA Piper UK to advise on best practices within domestic and international legal frameworks for preventing corruption within climate solutions. Additionally, the firm’s environmental magazine “Green Wise” provides clients pertinent information on local sustainability issues, including legislative environmental concerns and corporate best practices.


In December 2022, DLA Piper Chile received its ISO 14001 certification demonstrating its proactive commitment to sustainability and climate change mitigation. Its team provides legal counsel to both domestic and multinational clients in some of the most significant renewables deals in the country.

Halpern is widely recognised for his influence in the renewables sector.

In 2022, pro-bono clients included Africa Dream, which promotes sustainable solutions in sub-Saharan Africa and Chile with volunteer projects, and GSG Nab Chile, a corporation promoting awareness of impact investing.

The firm is also active in thought leadership, having recently collaborated with the Financial Market Commission (CMF) and the North American Chilean Chamber of Commerce of New York for a seminar to discuss the implications of CMF’s General Rule No. 461 which requires public companies and other entities supervised by CMF to report their ESG policies, practices, and goals.



Leading transactional Mexican law firm Galicia Abogados S.C.‘s ESG and sustainable finance practice, which was formalised in March 2021, is led by Carlos Escoto and comprises a multidisciplinary group of experts assisting clients with matters ranging from supply chain management to climate litigation. Escoto and other key contact Mariana Herrero regularly advise clients from a range of industries, identifying and assessing risks and providing counsel to improve environmental performance.

The firm has been at the forefront of significant sustainable financing deals in the country. Guillermo Pérez Santiago and his team advised a group of banks on the offering of the first sustainable notes by Comisión Federal de Electricidad to the amount of $1.75bn. The proceeds will be used in whole or part to finance new or existing eligible green projects, including renewable energy, energy efficiency, clean transportation, and green buildings projects. In another first, Perez Santiago provided counsel to Grupo Herdez as issuer and Casa de Bolsa BBVA México (Grupo Financiero BBVA México) as the underwriter for the $1.538bn sustainability-linked bond which marks the first bond of its kind by Grupo Herdez.

The team also supported the initial purchasers (a syndicate of banks) on the offer and sale by GCC, formerly known as Grupo Cementos de Chihuahua, of $500m due 2032. Significantly, the interest rate is subject to the company meeting the sustainability performance target which includes a reduction in specific net kilograms of CO2 emissions from direct operations. 

The firm’s sustainability committee led by founding partner Manuel Galicia deals with the firm’s internal ESG efforts and works closely alongside the pro bono committee, headed by Humberto Pérez Rocha. Since joining the UN Global Compact in 2021, the firm has strategically integrated international standards through its ‘Sustainability Model’. The firm’s robust pro bono practice continues to support initiatives such as Ecokali, which facilitates sustainable entrepreneurship among indigenous communities.

Its Environmental and Natural Resources practice, co-led by Rodrigo Fernandez and Rodolfo Vouga, works across the spectrum of sustainability with a strong focus on ESG, forestry, and sustainable finance.

In what is considered one of the first major policies in the country directly addressing climate change, Fernandez and Vouga are cooperating with the public authorities on the drafting of new national regulation aimed at reducing carbon emissions in line with the Paris Agreement goals.

In a significant matter in the forestry space, the duo is assisting a client with the legal structuring needed to receive foreign financing for obtaining future carbon credits arising from the forestation and conservation of native forest reserves in Paraguay. Together they have also continued to support Paracel with a range of legal matters, including the preparation and filing of several forestry permit applications for the forestation of lands totalling nearly 100,000 hectares in different parts of the Oriental Region of the country.

In another ongoing highlight, Fernandez is acting for Paresa, a Coca-Cola licensee, in setting up a joint venture consisting of a new factory to recycle plastic for PET bottles.

On a pro bono basis, the firm is also providing legal advice to Sistema B Paraguay, the NGO fostering and certifying B Corps in the country.

The team often publishes thought leadership pieces relating to sustainability, such as a recent article by Fernandez about new regulations on offences and sanctions in forestry .
