Cabo Verde faces development challenges from multiple structural factors, including insularity, territorial discontinuity, fragility of ecosystems, and scarcity of natural resources, namely water and arable land. Climate change implications are amplifying these challenges. As an island extension of the arid Sahel zone, Cabo Verde faces severe water shortage, which the country addresses more and more through energy intensive desalination, using electricity produced largely by thermal power plants, which depend entirely on imported fossil fuels. The resulting high energy prices directly impact the cost of water production. In conjunction with climate change induced aridity, the energy-water-climate nexus presents the core development challenge for the country.

The global energy transition is affecting fossil fuel exporters from multiple angles. It is adding to longstanding uncertainties on relative movements of fossil fuel demand and supply—which impact fossil fuel-related exports, fiscal flows, investment and subsequently external and fiscal accounts, economic growth, and employment. While policymakers are very familiar with these challenges, they now also face expectations of a permanent decline in the long-run global demand for fossil fuels. Key factors that could determine country-level impacts include (i) the type of fossil fuel a country exports (ii) extraction costs and (iii) country characteristics. The monitoring and mitigation of fiscal risks will need to be stepped up. Fiscal policy also has a role in reducing domestic emissions, encouraging adoption of low-carbon technologies, and helping those most vulnerable to changes from the transition. Broader macroeconomic risks can be reduced by accelerating ongoing structural reforms that support alternative engines of growth. Low- or zero-carbon emission energy industries could offer new avenues that build on existing fossil fuel knowledge and infrastructure. Concurrently, improved financial regulation and supervision could reduce financial sector exposures. Finally, international coordination on the design and implementation of climate policy as well as international transfer schemes (financing and capacity development) could reduce uncertainties surrounding the transition path and associated adverse economic consequences.

The IMF’s Macroeconomic Model for the Energy Transition (GMMET) is applied to assess the climate-related measures in the U.S. 2022 Inflation Reduction Act (IRA). Explicitly accouting for corporate income tax funding and assuming no permitting delays for energy-related investment, the measures are expected to cut annual greenhouse gas emissions by 710 MMT by 2030, predominantly driven by more electricity generation from renewables combined with a rising share of electric vehicles. Aggregate output and inflation are not impacted significantly, while the fiscal costs amount to about $700 billion through 2030 (another $120 billion of fixed grants and loans are not modelled). In the presence of investment delays from permitting, emission cuts would be reduced by about a third. We also show that the IRA leaves room for sizable additional emission abatement at very low costs; by targeting electricity generation from coal and methane emissions from oil and gas industries.
