Environmental management plan
The Business Environmental Management Plan (PGA-E) is a tool that allows improving, in an organized manner, the environmental performance of the CNFL; since it guides and prioritizes the attention of all the significant environmental aspects, which have been identified in the different activities and productive processes of the company.
The PGAE is aligned with the strategic objective of the CNFL: "Consolidate the environmental sustainability of the company with a perspective of excellence in services and social responsibility".
The PGAE is aligned with the Environmental Policy of the CNFL and allows compliance with the provisions of Decree Nº36499-S-MINAET “Regulation for the elaboration of programs of institutional environmental management in the public sector of Costa Rica”.
The PGAE is composed of the environmental programs described below:
The C-Neutrality Program of the CNFL seeks to measure and disseminate, in a transparent manner, the emissions generated in the company's operating processes and be managed responsibly according to the different emission sources.
Key years to obtain C-Neutrality Recognition
The CNFL raised the objective of being a C-Neutral company in the 100% of its operations, to date we reiterate the commitment to maintain this certification granted by the Ministry of Environment and Energy (MINAE) within the Country Carbon Program Official Neutrality of the Government from Costa Rica.
In this way it seeks to optimize the use of natural resources and strengthen control of the risks inherent in changes in the climate system that affect the production and distribution of electricity (droughts, floods, tornadoes, thunderstorms).
The CNFL executes a series of actions to reduce the emissions generated in its operational processes, among which are:
The CNFL has a multidisciplinary team of internal verifiers, which annually identify opportunities for improvement within the C-Neutrality Program, prior to the verification process carried out by the competent Validation and Verification Body (OVV).
All the actions framed within the C-Neutrality Program allow us to offer our clients environmental benefits, a competitive business image according to the new demands of the national and regional market, with an effective participation in the mitigation of the effects of climate change, in accordance with the national policies of decarbonization of the economy and the international commitments acquired by our country in the Climate Change Summits.
As part of the commitment and actions developed by the CNFL, the removals in forest sinks located in the conservation areas of the company are calculated.
Forests are constituted by their nature and by the processes they develop, in one of the most important sinks of the planet and the CNFL has invested in the acquisition and conservation of approximately 2088 has under forest cover.
The quantification of the inventory of forest removals required the development of a robust methodology at the technical level, considering all the necessary elements to adequately estimate the total CO2 removed.
To quantify the removals, permanent measurement plots distributed within the company's properties were established, considering the life zone and the type of forest (primary and secondary).
For the year 2017, the inventory of forest removals quantified a total of 18.910,762 Ton / CO2.

Integral Water Management
The program was created with the objective of recording the consumption of drinking water of the company and implementing improvement opportunities that reduce the amount of water used and thus reduce the associated costs.
When comparing the annual consumption of drinking water registered in the 2008, with respect to the annual consumption of the 2017; It is observed that the CNFL has achieved in 10 years to reduce drinking water consumption by 47,6%.
This reduction is due to the implementation of improvements, addressed in rainwater harvesting activities (water harvesting):
|Dependence||Installed capacity (cubic meters)||Use of captured water|
|Transportation and Workshop Area (2013)||10||Carwash|
|Transformers Laboratory (2014)||10||Transformer washing|
|Central Valley Wind Farm (2015)||20||Food of administrative facilities|
|Sustainability Farm (2016)||36||Agricultural and forestry production|
|Civil Infrastructure Improvement Area (2017)||10||Construction|
