The Urban Nexus project started out as a bottom-up initiative operating primarily at the city level. GIZ and ICLEI provide customized technical assistance to cities depending on the thematic focus of the cities’ nexus pilot projects. However, national, regional and provincial-level legal, regulatory, and policy frameworks are crucial determinants for local decision-making with regard to the nexus sectors. As such, ICLEI is facilitating national – regional – local dialogues as a means to clarify issues impeding the implementation of proposed nexus pilot projects. National-local dialogues help bridge the gap across levels of government particularly in the areas of water including wastewater, energy, and land use as well as cascading finance to the local level. Iteration and continued follow-ups between the two levels of government further strengthens vertical integration. ICLEI also utilizes its various international events to further promote the nexus approach including cross-sectoral cooperation within local governments and across levels of government.

Water should be a priority in the EU policies due to its importance for the economy, environment, and quality of life of the European citizens. ICLEI has created an alliance with 25 cities to prepare a framework for European cities with the objective of achieving a more coherent and thus more effective representation and visibility for water at the EU level. ICLEI aims to achieve this by supporting the implementation of the European Union water policy and the SDGs through sustainable water management at local level.

Through CitiesWithNature (CWN), local and regional governments are able to enhance the potential of nature to provide essential ecosystem services and solutions for the overall health of human habitats and urban areas. Through this platform, cities can engage, connect, learn, share, act, and inspire each other in the way of biodiversity and urban nature. ICLEI enables its local and regional constituency to access and influence global biodiversity processes and provides a one-stop-shop, or “big tent” under which projects, initiatives, and programs aimed at enhancing nature can be celebrated, shared, and promoted. ICLEI develops strategic global partnerships and the ongoing and continuous development of the various components of the CWN platform. CWN is recognized by the SCBD as the official vehicle for local and subnational governments to report their commitments and ambitions for the post-2020 Global Biodiversity Framework.

ICLEI provides awareness raising and capacity building to all spheres of government in mainstreaming biodiversity, through guidance on vertical and horizontal integration to ensure successful implementation of biodiversity strategies and action plans (BSAPS); clarifies the role and contribution to be made at national, subnational and local level; and provide practical technical guidance to national, subnational and local governments in 13 areas of action to promote integration, coordination and cooperation in developing and implementing National Biodiversity Strategies and Action Plans under the Convention of Biological Diversity.

ICLEI supports the sub-national governments’ initiative on achieving Aichi Biodiversity Targets. Aichi Prefecture called for a group of leading sub-national governments showing significant efforts for achieving the Aichi Targets. The initiative was established during CBD-COP13 in Cancun, Mexico in 2016 and joined by a significant number of sub-national governments. ICLEI supported its launch and is contributing to develop their joint activities toward COP14 and beyond.

The goal of this project is to mainstream biodiversity, nature-based solutions and ecosystem management, seek recognition for these as cross-sectoral tasks and integrated them in subnational Biodiversity Strategy and Action Plans and sector plans in three model city-regions. ICLEI launched the four-year INTERACT-Bio project in three Global South countries: Brazil, India and Tanzania. ICLEI is using a co-creation and co-production approach to implement the project activities. Through the project, city-regions will align their planning with their National Biodiversity Strategy and Action Plans (NBSAPs), which are required by the Convention on Biological Diversity (CBD). Through strengthened cooperation between the different levels of government, subnational action in support of the NBSAPs is promoted and enabled. Such collaborative approaches will ultimately support nations to accelerate biodiversity goals.

Using empirical research, ICLEI is developing a framework and tools to assess changes in food-water-energy nexus, their related trade-offs and the building of innovative capabilities in cities for developing innovative solutions to the food, water and energy nexus and manage green and blue infrastructure at the urban level. ICLEI is supporting the development of frameworks and tools that guide urban governance on the food-water-energy nexus, delivering innovative solutions to mitigate climate change and biodiversity loss, while advancing development goals from food security to job creation across cities worldwide. The project assesses the changes in trade-offs of food-water-energy nexus (FWEN) in green and blue infrastructure (GBI) and their association with spatial planning and governance in eight cities using empirical cases. This will provide a better understanding of the barriers that hinder innovative and integrated FWEN approaches using GBI at different scales; and look for the common features of diverse interventions.

Since 2008, ICLEI’s Cities Biodiversity Center (CBC) has convened successive summits as official parallel events to the Conference on Biological Diversity COP, to enable local and subnational governments engagement. These Summits have resulted in strong political outcomes, including the Quintana Roo (2016) and Sharm El-Sheikh (2018) Communiques, Nagoya Plan of Action on Subnational Governments, Cities and Other Local Authorities for Biodiversity (2011 – 2020), adopted at COP 10 in 2010, and of many decisions on local and subnational governments. Through these outcomes, ICLEI CBC has shaped a global policy environment that supports local and regional governments in their efforts to scale up and mainstream nature in sustainable urban development worldwide. ICLEI has also developed a dedicated website for local and subnational governments to advance the Action Agenda for Nature and People and the post-2020 Global Biodiversity Framework and holds monthly informational webinars. The CBC supports the work of CitiesWithNature.

ICLEI is responsible for project implementation in all four partner cities, including preparation of Climate Resilient City Action Plan for four Indian partner cities – Coimbatore, Rajkot, Siliguri and Udaipur – that addresses both climate change adaptation and climate change mitigation using ClimateResilientCities methodology; strengthening the capacities of cities to identify, plan and implement measures for reducing greenhouse gas emissions and for enhancing resilience to climate change; implementation of quick win projects to showcase reduction of GHG emissions; identification and planning for bankable projects based on requirements of the cities for large scale implementation of climate resilience building activities; and peer learning and exchange. Measures developed as a result of this project are being integrated in municipal budget to mainstream climate resilience in city development.

ICLEI is the lead author, supported by groups of city and carbon accounting experts from various fields, in the development of industry standards for local government GHG emissions accounting in the US. The development of the U.S. Community Protocol, the Local Government Operations Protocol, and the Recycling and Composting Protocol positioned ICLEI as exclusive experts in local government carbon accounting. Recognizing this expertise, ICLEI was asked to contribute to the development of the Global Protocol for Community Scale GHG emissions (GPC) and is currently working on an update to the U.S. Community Protocol to better account for forestry and land use changes. ICLEI continues to provide technical guidance for the application of the protocols to cities and practitioners around the world.
