Deep and Shallow Decarbonization in Supply Chains
No full textThis paper examines how suppliers adjust their decarbonization choices when major customers obtain validated emission-reduction targets. Using global supplier-customer links matched to firm-level emissions and project-level data from voluntary carbon registries, the analysis shows that downstream climate pressure elicits both real and symbolic responses, but in systematically different ways across suppliers. On average, treated suppliers become more likely to adopt climate targets of their own. High-emission suppliers subsequently reduce their emission intensity relative to comparable firms, indicating meaningful operational adjustments. Low-emission suppliers, by contrast, do not further reduce emissions; instead, they expand their use of carbon credits, sharply increasing offset intensity as a lower-cost alternative to additional physical abatement. These offsets disproportionately originate from lower-rated projects, suggesting that increased demand does not translate into pressure for higher-quality credits. Overall, downstream climate commitments induce a sorting in decarbonization strategies: high-emission suppliers undertake substantive reductions, while low-emission suppliers rely more heavily on market-based mechanisms to meet customer expectations

Services Competitiveness for Growth and Jobs in Indonesia
No full textIndonesia’s services sector has emerged as a key driver of economic growth and employment. Services have also been the driving force of global trade and investment. Advances in technology are expected to further improve the tradability of services, creating new opportunities for Indonesia. With the right policies, Indonesia can capitalize on the ongoing reconfiguration of global value chains (GVCs) and the increasing demand for services. Under the Job Creation Omnibus Law, Indonesia substantially opened services sectors to foreign investment. Significant barriers to services hinder Indonesia’s ability to compete in global markets and access to essential imports of services. Policies to shield key sectors and firms may have supported growth and job creation, but their effectiveness is approaching their limits. Addressing barriers to services will be crucial to achieving Indonesia’s development objectives and other national priorities. Looking ahead, Indonesia has set ambitious targets for the growth of services exports in its 2025-2029 Medium-Term National Development Plan. This report provides a first comprehensive assessment of the role of services and related policies in Indonesia’s economy, incorporating both backward- and forward-looking perspectives. Chapter 1 provides introduction. Chapter 2 looks back at the past decade to analyze how services contributed to value addition, job creation, domestic and foreign investment, and export revenues. Chapter 3 provides a systematic review of the regulatory framework, examining domestic and cross-border policies affecting the four modes of services delivery and within Indonesia’s trade agreements evaluates the restrictiveness of regulatory measures. Chapter 4 looks ahead, quantifying the impacts of various policy alternatives on Indonesia’s growth and development objectives. Finally, chapters 5 and 6 provide detailed deep dives into two key service sectors - information and communication services and transport services - both critical for enhancing Indonesia’s value addition, economic growth, and development

Urban Heat: Planning and Implementing Investments for Heat Resilience
No full textThis Technical Note builds directly on the Urban Heat Risk Assessment Technical Note, which focuses on diagnosing heat hazards, exposure, and impacts in urban areas. In many cities, the analytical understanding of extreme heat has advanced rapidly, supported by improved climate data, spatial analysis, and growing evidence on health, productivity, and infrastructure impacts. As a result, the nature and severity of urban heat risks are increasingly well documented. This note responds to a different, but closely related, challenge. Its purpose is not to further assess or quantify heat risks, but to support cities in translating existing evidence into concrete, investable actions and project concepts. It is intended for contexts where the need to act on heat is already recognized, but where the pathway from assessment to implementation remains unclear
Local Visibility vs. Global Integrity: Evidence from Corporate Carbon Offsetting
No full textAlthough the climate impact of carbon abatement is geographically invariant, this paper documents limited geographic fungibility in voluntary carbon markets. Firms disproportionately retire offsets in countries where they operate. The paper contrasts an Information Channel, whereby local presence improves project screening, with a Goodwill Channel, whereby supporting local projects enhances reputational visibility. The evidence supports the latter. Offsets retired within firms’ operational footprints exhibit systematically lower project quality than those sourced abroad, revealing a negative local quality gradient. This pattern persists with firm experience and generates equilibrium price-quality decoupling: in jurisdictions with concentrated local demand, prices become less responsive to project quality. The resulting distortions can generate a “market for lemons” dynamic, reallocating climate finance away from high-abatement-potential regions toward areas with greater multinational presence. Strategic corporate incentives thus weaken the allocative efficiency of voluntary carbon markets

Penerapan Irigasi Sprinkle untuk Efisiensi Penyiraman Lahan Hortikultura di Lereng Arjuno-Welirang
No full textDesa Sumbergondo di Kecamatan Bumiaji, Kota Batu, merupakan sentra pertanian hortikultura dengan topografi berbukit yang menghadirkan tantangan pada proses penyiraman. Sistem penyiraman manual yang masih digunakan petani membutuhkan waktu sekitar 4 jam untuk lahan seluas 3.200 m², menimbulkan beban fisik yang tinggi, serta menyebabkan distribusi air tidak merata antara lahan bagian atas dan bawah. Permasalahan tersebut berdampak pada rendahnya efisiensi kerja, kelelahan petani, serta pertumbuhan tanaman yang tidak optimal. Melalui program pengabdian masyarakat ini diterapkan teknologi tepat guna berupa sistem penyiraman berbasis sprinkle. Tahapan kegiatan meliputi survei kebutuhan lahan, perancangan sistem, instalasi pompa dan jaringan pipa, uji coba, serta evaluasi kinerja. Hasil implementasi menunjukkan adanya peningkatan efisiensi penyiraman yang signifikan. Jika sebelumnya penyiraman membutuhkan waktu minimal 4 jam, kini dapat diselesaikan dalam 1,5 jam, sehingga terdapat efisiensi waktu 62,5%–75%. Penggunaan pompa irigasi Tesla WP 20 CX dengan kapasitas 600 liter per menit dan enam titik sprinkle yang dapat dipindahkan memungkinkan distribusi air lebih merata hingga ketinggian 23 meter. Selain itu, beban fisik petani berkurang secara nyata, di mana 85% petani menyatakan penyiraman menjadi lebih ringan. Pengukuran kelembaban tanah menunjukkan distribusi air lebih homogen, dengan rata-rata 65%–72% pada berbagai zona lahan. Observasi awal memperlihatkan pertumbuhan tanaman yang lebih seragam dibandingkan kondisi sebelumnya. Dengan demikian, penerapan sistem sprinkle mampu menjawab permasalahan utama petani hortikultura terkait efisiensi waktu, beban fisik, dan distribusi air, serta berpotensi meningkatkan produktivitas hasil panen di lahan berbukit
The Global Sanitation Crisis: A Systems Approach to Resilient Citywide Inclusive Sanitation
No full textThis background paper highlights the urgent need for climate‑resilient sanitation systems as cities face increasing climate‑related pressures. The growing impacts of extreme weather events expose the deep interconnections between sanitation and other essential urban systems, including water supply, energy, transportation, stormwater, and solid waste management. Because these systems are tightly linked, the failure of one component can trigger cascading disruptions across multiple services, amplifying risks to public and environmental health. Sanitation failures can affect non‑sanitation sectors, just as breakdowns in other systems can compromise sanitation service delivery. These interdependencies underscore the importance of integrated resilience planning, where urban sanitation is recognized as a foundational element of overall city resilience. The paper also highlights the vital connection between sanitation and food systems through the safe reuse of wastewater and sludge, emphasizing the increasing relevance of circular economy approaches in fostering sustainable, climate‑adaptive transformations in the sector. With a primary focus on adaptation, the paper articulates why a systems‑based approach is essential for strengthening urban sanitation resilience and ensuring service continuity under climate variability and extreme events
From Training to Earning: The 7-Year Impact of Dual Apprenticeships on Youth Employment
No full textThis paper studies the long-term impacts of dual apprenticeships on youth employment in a high-informality labor market. A Randomized Controlled Trial in Côte d'Ivoire with four follow-up surveys collected over seven years shows that dual apprenticeships have sustained impacts: youth earnings increase by 14 to 20 percent two to five years after program completion. Gains are observed across the earnings distribution, and the share of youth in working poverty — with earnings below the minimum wage — decreases by 11 percent. Importantly, results highlight a distinct pathway whereby training raises earnings through self-employment, with no impact on access to wage employment. Youth perform more complex, non-routine tasks, consistent with improved technical skills and productivity. In a setting where formal wage jobs are rare, these findings show that dual apprenticeships constitute an effective and inclusive skilling model that raises earnings in self-employment and reduces working poverty
