Environment and Energy Landscape in Latin America and the Caribbean: An Analysis of Trends 2020-2030

These mechanisms refer to alternatives, complements, or supplements to nature management that depend on market forces, financial mechanisms, or other economic instruments to align economic incentives with environmental outcomes. Payment for ecosystem services (PES) is a key market-based mechanism in LAC, where a beneficiary/user of an ecosystem service makes a payment to the provider of that service. PES programs have flourished in the region since the first national PES program was established in Costa Rica. These programs have mainly focused on local-level water solutions, with water funds leading the way in the region's use of PES. LAC is the leading region in the world on water-focused PES, with 25 funds created and 15 under development. PES programs have been shown to deliver a range of environmental, economic, and social benefits. Environmental benefits include decreased deforestation and degradation, improved water quality and availability, and reduced soil erosion. Economic benefits include increased income for smallholder farmers or landowners, although financial benefits are typically not enough to cover the opportunity cost of using natural resources for other productive purposes. Social benefits include expanded access to income and services for vulnerable populations, such as indigenous and Afro-descendant communities. Tradable permits and quotas (P&Q) are another market-based mechanism in LAC, where acquired rights are established to limit the use or exploitation of resources to a maximum level that represents an optimal usage level. P&Q have grown in the region, with up to 2017, the PINE database from OECD reporting 15 tradable permit systems. Mexico started piloting an emissions trading system in 2020, while Colombia, Chile, and Brazil have expressed interest in establishing one. Environmental taxes are a charge whose tax base is a physical unit that has a proven specific negative effect on the environment. Environmentally related tax revenues have slowly grown in the region, from 0.9% to 1.1% of GDP on average in 2018 in LAC, well below the OECD average of 2.3%. In the last six years, Mexico, Chile, Argentina, and Colombia have implemented carbon taxes, and Brazil has expressed interest, signaling the potential to increase. Green bonds are a type of loan allocated to environmental-related projects that companies, governments, and banks use to finance projects. From 2014-2019, the annual green bonds issuance volume in Latin America and the Caribbean grew 18-fold to $3.6 billion in 2019. Green bonds can be used to mobilize significant funds for large-scale projects and build on existing capital markets and finance ecosystems. Each of these market-based mechanisms has distinct advantages and challenges. PES makes the value of ecosystems explicit, enabling greater willingness to manage these assets optimally, but may require significant monitoring to ensure ecosystems are maintained as intended. Tradable P&Q limit the use or exploitation of resources to a maximum level, but establishing the appropriate cap may be difficult due to uncertainty or limited data. Environmental taxes generate revenue that can be used for positive purposes, but can be difficult to generate political support and/or to operationalize. Green bonds can be used to mobilize significant funds for large-scale projects, but dependence on underlying finance ecosystems means existing inequities and biases in these systems are likely to shape the green bond market as well. Overall, market-based mechanisms for environmental management and conservation have the potential to deliver significant environmental, economic, and social benefits in LAC. However, each mechanism has its own advantages and challenges, and careful consideration must be given to the design, implementation, and monitoring of these programs to ensure their effectiveness and sustainability.
