Geopark Teskei in Kyrgyzstan is experiencing growing tourism demand. While tourism presents economic opportunities, continued expansion of conventional mass tourism risks increasing waste and wastewater pressures, degrading natural assets, and undermining the long-term value of the destination. 

The Nature-Based Infrastructure Global Resource Centre conducted a SAVi assessment to compare two tourism pathways over 25 years: a Conventional Tourism Scenario and a Sustainable Tourism Scenario centered on ecosystem protection and nature-based infrastructure. 

The sustainable pathway includes investments in improved waste and wastewater management systems, restoration of degraded landscapes, soil erosion control, biodiversity protection, and low-impact tourism infrastructure. 

The analysis finds that the sustainable pathway delivers significantly stronger economic performance over 25 years. It generates USD 250 million in net benefits, compared to USD 17.6 million under conventional tourism. For every USD 1 invested, sustainable tourism returns USD 8.88 in combined economic, social, and environmental value. 

This difference is driven by a shift in the tourism model. The sustainable pathway reduces reliance on high-volume, low-spending tourism and instead attracts visitors who generate higher value per trip. At the same time, investments in nature-based infrastructure, such as wetlands and native vegetation, reduce waste management costs and help prevent environmental degradation and infrastructure damage. 

The findings show that sustainable tourism delivers stronger long-term economic results than continued mass tourism.

The inventory provides relevant information on a variety of NbS projects in Belize, including the NbS approach taken, the climate and biodiversity risks addressed, the intended beneficiaries, and the ecosystems targeted. It provides a useful compilation of NbS projects for the Belizean government, protected area managers, adaptation and conservation practitioners, civil society organizations, communities, and funders to help them understand the landscape of implementation in Belize and facilitate further adoption and mainstreaming of NbS.

Johannesburg’s Jukskei River catchment is one of the city’s most degraded urban ecosystems. Rapid urbanization, informal settlements in riparian zones, invasive alien species, solid waste dumping, and aging infrastructure have intensified flooding, sewage contamination, and extreme heat. These pressures disproportionately affect vulnerable communities and place growing strain on public health systems and municipal budgets. 

The Scaling Urban Nature-based Solutions for Climate Adaptation in Sub-Saharan Africa (SUNCASA) project supports ecosystem restoration across the Jukskei River catchment. Implemented by the International Institute for Sustainable Development and the World Resources Institute, the project includes riparian restoration across 469 hectares, urban tree planting with 46,000 trees, removal of invasive alien species, solid waste management, and the development of multifunctional green infrastructure along the river corridor. 

The Nature-Based Infrastructure Global Resource Centre conducted a SAVi assessment to evaluate the full life-cycle costs and benefits of these interventions compared to a business-as-usual scenario. 

Over a 25-year period, the NbS interventions will generate USD 8.6 million in net benefits. For every USD 1 invested, Johannesburg will receive USD 3.06 in economic, social, and environmental returns, and the investment pays for itself within 7 years. 

The largest share of benefits comes from improved water quality. Avoided health costs linked to water pollution amount to USD 3.7 million over 25 years. Additional benefits include reduced flood damage, lower invasive alien plant management costs, carbon sequestration, and employment creation. 

This assessment shows that restoring the Jukskei River is not only an environmental intervention but a financially sound strategy that improves public health, reduces long-term municipal expenditure, and strengthens urban climate resilience in Johannesburg.

The EUDR is among the most ambitious environmental trade measures ever enacted, requiring that commodities like cocoa, coffee, and timber sold in the European Union are proven to be deforestation-free and legally produced. The EUDR’s reach is global, but its implications are particularly significant for Africa, which supplies a substantial share of the commodities in scope and where millions of producers depend on EU market access for their livelihoods. To help producers navigate these strict rules, new timelines offer a strategic window for preparation, with large companies needing to comply by late 2026 and smaller enterprises by mid-2027. This period is a vital opportunity for African exporters to strengthen their data systems and ensure their products can still reach European markets without disruption. 

Voluntary sustainability standards are essential tools in this transition. While certification alone cannot replace due diligence obligations, robust regional standards provide producers with the practical infrastructure they need: traceability frameworks that link products to specific plots of land, risk assessment systems, and verifiable documentation that European buyers now require. By using regional systems and sustainability standards that align with local laws and farming conditions, producers can manage compliance costs while providing the high-quality data and risk assessments that European buyers now demand. 

For Africa, this is where the ARSO comes in. As the continent's intergovernmental standard-setting body, ARSO is uniquely positioned to align African production systems with EUDR requirements in a way that reflects African legal contexts and farming realities. This paper benchmarks ARSO's agriculture and forestry standards against the EUDR to identify where alignment is strong, where gaps remain, and what targeted updates would allow ARSO standards to become a reliable, continent-led pathway to support compliance. This will support ARSO’s goal to protect market access for African farmers, ensuring that new environmental regulations support sustainable growth and inclusive trade across the continent.

From tracking microplastics through entire ecosystems to sending our team to the United Nations to shake up global policy, we’re making sure our data actually changes the world. 

We also went even more high tech, using artificial intelligence to predict lake thaws with crazy accuracy, while our oil-sniffing dogs proved they’re 100% reliable at detecting oil spills when they happen. From Indigenous partnerships to an upcoming ribbon cutting on the next Centre for Climate and Lake Learning, we’re not just studying the future of water. We are building it.

The ripple effect is just getting started...

Following our 2024 report, "Rethinking Investment Treaties: A roadmap", the International Institute for Sustainable Development launched a public consultation on this theme between June and September 2025, seeking input on policy priorities and design for investment treaties from policy-makers, investors, experts, academics, and other members of the investment community. 

The Rethinking Investment Treaties public consultation involved a two-part survey. The main survey asked the respondents to choose and rank what they considered to be the most pressing policy problems of investment governance, as well as questions about the best tools to address these issues and the potential role of treaties in solving them. The second survey was optional and designed to focus on more technical aspects of investment treaty reform.

The global transition away from fossil fuels (TAFF) has entered an implementation phase. While clean energy deployment continues to accelerate and investment increasingly flows toward renewables, electrification, and clean technologies, fossil fuel production and consumption plans remain misaligned with climate science and expose countries to growing geopolitical, economic, and fiscal risks. 

Political appetite for structured cooperation is evident. More than 80 countries endorsed the call for a global roadmap on transitioning away from fossil fuels at the 30th United Nations Climate Change Conference (COP 30), and 2026 presents multiple diplomatic and technical processes that can help translate commitment into delivery. The central challenge is no longer simply setting ambition, but ensuring coherence, coordination, and implementation across national plans, international coalitions, and sectoral initiatives. 

This paper focuses on the practical question of how to design effective roadmaps for transitioning away from fossil fuels—at both global and national levels. Its primary contribution is a structured review of selected case studies of existing initiatives, alliances, and national processes. These examples provide concrete lessons on what works, where gaps remain, and how principles such as scientific alignment, justice, national ownership, and coordinated international support can be operationalized. A detailed description of each case study can be found in the accompanying paper, Progressing the Transition Away From Fossil Fuels: Lessons from case studies. 

Drawing from these case studies, the report identifies core principles, essential planning elements, and international coordination needs that should underpin TAFF roadmaps. It aims to inform ongoing processes in 2026—including the Brazilian COP 30 Presidency’s global roadmap initiative—and beyond, and to support countries in developing coherent, whole-economy national TAFF roadmaps that are just, orderly, and aligned with science.

Various approaches have been proposed to address GDP’s limitations and introduce complementary metrics, such as those that measure the quality of life, environmental sustainability, inequality, labour, health, and social protection metrics. Yet even these systems often fail to fully recognize contributions that are vital to society, particularly those disproportionately carried out by women. 

This report explores the care economy and opportunities to integrate it into efforts to move beyond GDP. The authors summarize current approaches to measuring the contribution of care work, using examples from around the world and examining the level of integration of care work and its role in integrating human capital into alternative metrics. They also offer recommended next steps to meaningfully measure the care economy’s contributions within beyond-GDP frameworks.

Canada’s province of Alberta implemented North America’s first industrial carbon pricing system in 2007. In 2025, large industrial emitters in every region of Canada are covered by either a regional carbon pricing system or the federal system. This report examines the histories and designs of five major Canadian carbon pricing systems: Alberta’s Technology Innovation and Emissions Reduction regulation, British Columbia’s Output-Based Pricing System, Ontario’s Emission Pricing System, Québec’s Cap-and-Trade, and the federal Output-Based Pricing System. 

The report provides an overview of the industrial and emissions context for each system and outlines their approaches to benchmarking, compliance flexibility, stringency adjustments, and other key design parameters. It also reviews market outcomes, highlighting risks such as credit oversupply and uncertainty, and distills lessons learned from each system’s implementation.

Despite 2 decades of discussions, implementing community-based adaptation at scale remains a challenge. Community-level participatory climate vulnerability assessments provide the foundation for effective locally led adaptation by linking local insights on climate impacts and vulnerabilities with climate projections. They can offer a nuanced understanding of current and future risks to diverse genders, social groups, ecosystems, and livelihoods.

Along with three other international organizations—CARE, the Food, Agriculture and Natural Resources Policy Analysis Network, and the International Union for Conservation of Nature—and local partners, we applied participatory climate vulnerability assessment processes in nearly 100 communities in Mozambique, Zambia, and Zimbabwe from 2024 to 2025. This report identifies six takeaways:

1. Respectful community engagement should build on existing climate and vulnerability data, but reliable information is not always available or accessible.
2. Integrating community knowledge with scientific climate data requires a deep understanding of climate science and a focus on overcoming cognitive biases.
3. Involving local governments and other key actors at the outset and throughout the participatory climate vulnerability assessment process is essential to institutionalizing community-based adaptation.
4. Conducting a participatory climate vulnerability assessment during ongoing climate, biodiversity, political, and economic crises requires sensitive communication and effective expectation management.
5. Transparently communicating what participatory climate vulnerability assessment processes can and cannot achieve—and why—is essential to keep communities engaged.
6. Blending the approaches and expertise of diverse partners fosters a shared understanding and ownership across large consortia, ultimately bolstering the quality of the participatory climate vulnerability assessment process and results.

While these lessons may seem familiar, practitioners should not take them for granted—much remains to be done for community-based adaptation to realize its potential. This report provides detailed recommendations for each lesson, targeting adaptation and development practitioners interested in advancing community-based adaptation and community-level participatory climate vulnerability assessments.
