Climate Change

The Special Report on Global Warming of 1.5°C identifies cities and urban areas as one of four critical global systems that can accelerate and upscale climate action, but recognizes this will require major transitions in how both mitigation and adaptation are undertaken. This C40 Summary for Urban Policymakers has been produced in discussion with city practitioners and policymakers, as well as leading city networks and non-governmental organizations.

An analysis of the contribution C40 cities can make to delivering the Paris Agreement objective of limiting global temperature rise to 1.5 degrees.

Each tier of government, including the national, regional and local levels, has a unique and potentially complementary role to play in delivering low emission and climate resilient development. This means that effectively coordinated multilevel action can help nations implement their Nationally Determined Contributions (NDCs). This joint policy briefing explores the need for enhanced multilevel governance to implement the NDCs.

This case study documents the recovery of the biogas generated in the wastewater treatment process and highlights its importance within the framework of the Local Strategy for Climate Change of the Municipality of Almada. As a coastal city, progressive water and wastewater management toward a carbon efficient urban water cycle is a priority for the City Council of Almada.

The third edition of the European Commission's guidance on implementing green public procurement. This version has been updated to reflect the updated 2014 Procurement Directives. The Handbook was compiled by ICLEI under a contract with the European Commission.

The local government plays a crucial role in defining and harnessing the benefits of urban low emission resilient development pathways for its community. However, this is also the level of government which has to deal with severe capacity constraints, both staff and financial, and faces conflicting priorities on a daily basis. This implies the need to optimize time and staff capacity wisely. The Solutions Gateway supports this view, to guide, showcase examples of good practice, with a focus on proven solutions for low emission and sustainable development.

Paris Agreement led onto the beginning of a new era where climate action is accelerated, coordinated and properly financed. It is clear that climate action at local level is critical to ensure bottom-up results are achieved, that in turn support accomplishment of international goals and target set in Paris Agreement.  Yet we also know that local governments cannot do this alone, they need support and engagement from all levels of government.

National, local and other subnational governments need to work together to track performance and implement effective, coordinated climate action, with the aim to progressively raise local, national and global ambitions. Linking national and subnational climate reporting is a key element for effective climate governance. This report is a snapshot of the targets, performance inventories, action plans and actions from the carbonn Climate Registry (cCR), of the most widely used subnational climate action reporting systems in the world.

This is a synthesis report of data from the carbonn Climate Registry. It looks at subnational alignment with the 1.5-degree target, key climate hazards and how two-way dialogue and data-sharing can raise climate ambitions. Special attention is given to the importance of integrated Measuring, Reporting and Verification (MRV) systems, and how such systems can help coordinate, target and build support for climate initiatives.
