The report and its recommendations should also be careful to not impinge upon areas that are still unfolding, such as the RST, crisis response, and CD provision, to avoid unnecessary duplication of efforts and ensure that a coherent and evenhanded framework is in place. I offer qualified and/or partial support to the recommendations, as discussed below, to serve better our SDS members.

Carbon pricing is considered the most efficient policy to reduce greenhouse gas emissions but it has also been conjectured that other policies need to be implemented first to remove certain economic and political barriers to stringent climate policy. Here, we examine empirical evidence on the the sequence of policy adoption and climate policy portfolios of G20 economies and other major emitters that eventually implemented a national carbon price. We find that all countries adopted carbon pricing late in their instrument sequence after the adoption of (almost) all other instrument types. Furthermore, we find that countries that adopted carbon pricing in a given year had significantly larger climate policy portfolios than those that did not. In the last part of the paper, we examine heterogeneity among countries that eventually adopted a carbon price. We find large variation in the size of policy portfolios of adopters of carbon pricing, with more recent adopters appearing to have introduced carbon pricing with smaller portfolios. Furthermore, countries that adopted carbon pricing with larger policy portfolios tended to implement a higher carbon price. Overall, our results thus suggest that policy sequencing played an important role in climate policy, specifically the adoption of carbon pricing, over the last 20 years.

Climate change is among humanity’s greatest challenges, and the Middle East and Central Asia region is on the frontlines of its human, economic, and physical ramifications. Much of the region is located in already difficult climate zones, where global warming exacerbates desertification, water stress, and rising sea levels. This trend entails fundamental economic disruptions, endangers food security, and undermines public health, with ripple effects on poverty and inequality, displacement, and conflict. Considering the risks posed by climate change, the central message of this departmental paper is that adapting to climate change by boosting resilience to climate stresses and disasters is a critical priority for the region’s economies.
Samoa is highly exposed to natural hazards such as tropical cyclones, earthquakes, tsunamis, droughts, and floods. These damage economic growth and impact debt sustainability adversely. Increasing frequency and intensity of coastal storms are likely to amplify damage to infrastructure and livelihoods. Slow-moving climate stresses such as sea level rise and increasing heat hazard are also likely to impact potential growth in the main economic sectors such as agriculture, fisheries, and tourism.

This paper discusses and analyzes various international mechanisms to scale up global action on climate mitigation and address the policy gap in this area. Despite the new commitments made at COP 26, there is still an ambition and a policy gap at the global level to keep temperature increases below the 2°C agreed in Paris. Avoiding the worst outcomes of climate change requires an urgent scaling up of climate policies. Recent policy proposals include the idea of common minimum carbon prices, which underlie the IMF’s international carbon price proposal (Parry, Black, and Roaf 2021) and the climate club proposal of the German government. While global carbon prices are not a new idea, the new elements are the use of carbon price floors—which allow countries to do more if they wish—and the differentiation of carbon price floors by level of development. In the absence of international coordination, countries with ambitious climate policies are considering introducing a border carbon adjustment mechanism to prevent domestic producers from being at a competitive disadvantage due to more ambitious domestic climate policies. An interesting question from the global perspective is whether border carbon adjustment would deliver substantial additional emissions reductions or incentivize other countries to join a carbon price floor agreement.

Natural disasters and climate change are existential threats to Grenada, with annual losses from these events estimated at 1.7 percent of GDP. Grenada has proactively pursued resilience-building, with its Climate Change Policy and National Adaptation Plan providing detailed roadmaps for policymakers. However, the challenges are increasing, including from slow-moving effects owing to the rising sea level, even as implementation capacity and resource constraints remain significant impediments. The COVID-19 pandemic has amplified those challenges by increasing risks and tightening Grenada’s fiscal space.
