Bridging the Gap Between Energy and Climate Policies in Brazil: Policy Options to Reduce Energy-Related GHG Emissions

Brazil is facing a series of important policy decisions that will determine its energy future over the next several decades, with important implications for the country's economic competitiveness, the well-being of its citizens, and the global climate. The decisions concern the direction of approximately 0.5 trillion U.S. dollars of anticipated investment in energy infrastructure over the next decade -- which can either lock in carbon-intensive infrastructure, or advance Brazil's position as a leader in the low-carbon economy. This report examines Brazil's key energy-related GHG emitting sectors through a climate lens in order to offer recommendations for a more integrated approach that can more effectively reconcile energy and climate needs. It begins with an overview of Brazil's past energy and GHG emissions profiles, current pledges and future trends, and a discussion of the implications for a possible allocation of the remaining global carbon budget. Next, it reviews available scenarios for Brazil's energy-related GHG emissions in order to identify key drivers and results and compare them to a given allocation of the global carbon budget. It then focuses on the top emitting subsectors -- transport, industry, and power generation -- to identify key abatement opportunities. The report concludes with recommendations regarding a portfolio of policies and measures that could achieve both climate and energy objectives

Avoiding Carbon Lock-In: Policy Options for Advancing Structural Change

A major obstacle for the transformation to a low-carbon economy is the risk of a carbon lock-in: fossil fuel-based ('dirty') technologies dominate the market although their carbon-free ('clean') alternatives are dynamically more efficient. We study the interaction of learning-by-doing spillovers and the substitution elasticity between the clean and the dirty sector in an intertemporal general equilibrium model. We find that the substitution possibilities between the two sectors have an ambivalent effect: although a high substitution elasticity requires less aggressive mitigation policies than a low one, it creates a greater lock-in in the absence of regulation. The optimal policy response consists of a permanent carbon tax as well as a learning subsidy for clean technologies. A single policy instrument can also avoid high welfare losses, but a more stringent mitigation target can only be achieved at painful costs. We demonstrate that the policy implication of [Acemoglu et al. 2012] is limited in scope. Our numerical results also highlight that infrastructure provision is crucial to facilitate the low-carbon transformation.structural change, low-carbon economy, carbon lock-in, mitigation policies, learning-by-doing

Decentralization of Governance and Financing of Public Roads in the Philippines in the 1990s

A major theoretical as well as political approach to transport infrastructure investment and management is the idea that such services are public goods and should not be subject to private market considerations. However, from time to time, public provision seems to fail, which increases the importance of various forms of private sector participation. Assessing the impact of devolution on the country's road infrastructure, the author underscores the lack of coherence in the design and redistribution of resources and responsibilities, which resulted in a coordination gap between national government agencies and local government units. An important insight is that the private provision of a public good may be feasible, for as long as its consumer-beneficiaries can be made to pay a use price, such that the revenue stream to the private provider is greater than the cost of construction, administration, and upkeep of the public good.infrastructure, devolution, decentralization, private sector participation, local government code, road network, road infrastructure, decentralized governance
