Environmental economics is a branch of economics that focuses on the study of environmental problems and their relationship to economic activity. The goal of environmental economics is to analyze how the economic decisions of individuals, businesses and governments affect the environment and how policies and solutions can be designed to promote sustainable and equitable development.
Environmental economics uses economic tools, such as environmental valuation, internalization of environmental costs, and economic incentives, to promote efficiency in the use of natural resources and reduce negative externalities of economic activity, such as pollution and climate change.
Among the topics of interest in environmental economics are waste management, biodiversity conservation, water management, climate change mitigation and adaptation, energy and sustainable mobility, among others.
Environmental assessment
Environmental valuation is a technique used in environmental economics to assign a monetary value to environmental resources and services that do not have a formal market. It is a process that seeks to quantify the benefits that people derive from the environment and the costs associated with their degradation or loss in the environmental economy.
Environmental valuation is based on the idea that natural resources and environmental services, such as air quality, water and landscapes, have an intrinsic economic value that can be quantified and taken into account in economic decisions. This approach recognizes that the environment is an economic good that must be managed efficiently and sustainably.
There are different methods of environmental assessment, which vary according to the type of environmental resource or service to be assessed and the specific conditions of the context. Some of the most commonly used methods include:
Methods of revealed preferences, which analyze the behavior of consumers in the market and allow inferring their willingness to pay for an environmental resource or service.
Methods of declared preferences, which rely on surveys and questionnaires to determine people’s willingness to pay for an environmental resource or service.
Travel cost methods, which measure willingness to pay to visit a protected natural area or a specific tourist resource.
Contingent valuation methods, which directly ask people how much they would be willing to pay to protect an environmental resource or service.
Internalization of environmental costs
The internalization of environmental costs is a key concept in environmental economics that refers to the process of including in the prices of goods and services the environmental costs associated with their production and consumption. These costs include, for example, the costs of air and water pollution, deforestation, biodiversity loss, climate change and other environmental impacts.
The internalization of environmental costs seeks to make prices reflect the true costs of production and consumption, including
Economic incentives
Economic incentives are tools used in environmental economics to motivate companies and consumers to make decisions that promote the protection and conservation of the environment. These are mechanisms that seek to align economic interests with environmental objectives and encourage the adoption of sustainable practices.
Among the most widely used economic incentives in environmental economics are:
Environmental taxes
They are taxes that are applied to the production or consumption of goods and services that generate negative environmental impacts. For example, a greenhouse gas emission tax can incentivize companies to reduce their emissions.
Environmental subsidies
They are financial incentives given to businesses and consumers who adopt sustainable environmental practices. For example, a subsidy for the installation of solar panels can incentivize the adoption of renewable energy.
Emissions trading systems
They are mechanisms that allow companies to buy and sell permits to emit greenhouse gases. Emission limits are set at national or regional level, and companies can buy permits if they need to issue more than allowed or sell permits if they issue less.
Renewable Energy Certificates
They are certificates that are issued to companies that generate energy from renewable sources, such as solar or wind. These certificates can be sold to other companies that want to demonstrate their commitment to renewable energy.
Payments for environmental services
They are payments made to landowners or local communities for the provision of environmental services, such as biodiversity conservation or protection of water sources. These payments can be financed by the public or private sector.
Waste management
Waste management is a process that seeks to minimize the amount of waste generated, and properly manage the waste that is generated, to reduce its environmental impact and protect public health. This includes all stages of the waste life cycle, from its generation to its final disposal.
The main stages of waste management are:
Prevention and reduction
It consists of avoiding the generation of waste and reducing the amount of waste generated, through the implementation of sustainable production and consumption practices.
Reuse and recycling
It consists of reusing materials and products that are no longer needed for their original use, or recycling them to give them a new use. These practices make it possible to reduce the amount of waste generated and reduce the extraction of raw materials.
Treatment
It consists of processing waste to reduce its volume, hazardousness and / or polluting potential. Examples of treatments are composting, incineration, sterilization, among others.
Final provision
It is the stage in which waste that cannot be treated or recycled is deposited. Final disposal must be done properly to minimize its environmental impact and avoid contamination of soil, water and air.
Waste management is a complex issue that requires the participation of multiple actors, including governments, businesses, organizations and citizens. To achieve sustainable waste management, it is necessary to implement policies and programs that promote the reduction, reuse and recycling of waste, as well as the implementation of clean and safe technologies for its treatment and final disposal.
Biodiversity conservation
Biodiversity conservation is a set of actions and strategies aimed at protecting and preserving the biological diversity of the planet, including the variety of species, ecosystems and natural habitats. This is essential for human well-being and the balance of ecosystems, and its loss can have serious consequences for people’s health and livelihoods.
To achieve biodiversity conservation, it is necessary to implement measures at the local, national and international levels, which address the causes of biodiversity loss and promote the protection and sustainable management of natural resources. Some of the main strategies for biodiversity conservation are:
Creation of protected areas
The creation of protected areas, such as natural parks, biological reserves and wildlife sanctuaries, allows to protect the ecosystems and natural habitats of the species.
Habitat restoration
The restoration of degraded habitats, such as forests, wetlands and rivers, is essential to recover lost biodiversity and improve the quality of life of local communities.
Control of hunting and fishing
Overhunting and overfishing can have a negative impact on biodiversity. It is necessary to implement measures to control hunting and fishing, and promote sustainable practices.
Promoting sustainable agricultural and forestry practices
Agriculture and forestry are human activities that can have a negative impact on biodiversity. There is a need to promote sustainable practices that enable responsible food production and exploitation of forest resources.
Education and awareness-raising
Education and public awareness is essential to promote biodiversity conservation. There is a need to promote the understanding and appreciation of biodiversity and its importance for human well-being and ecosystem balance.
Water management
Water management is a set of measures and actions aimed at the planning, use and conservation of water resources, with the aim of guaranteeing their availability and quality for present and future generations. This is essential to ensure food security, public health, economic development and environmental protection.
Some of the main measures for water management are:
Integrated water resources planning and management
Integrated water resources planning and management involves the coordination of different water uses (agriculture, industry, energy, human consumption, among others) and the conservation of aquatic ecosystems.
