The green economy model for India is a system dynamics model that has been customized to the national context in the structure of the model and input data. It also takes into account the key priorities for the country, incorporating primary and allied sectors affecting climate change at the national level. 

Tanzania has the sixth highest rate of urban population growth in the world, but so far it has been largely informal and unmanaged. This paper offers recommendations for managing Tanzania’s urban growth at the country level. 

This paper is a background review representing part of the initial phase of the Financing the Urban Transition work programme. The review builds on a growing body of research that highlights both the importance of national sustainable infrastructure and the need to develop more effective and efficient financing mechanisms for delivering compact, connected cities that meet the UN’s Sustainable Development Goals. While progress has been made in both these areas over the last five years, there remains a policy gap between the international/national level and the municipal level.

New mobility services could improve the lives of all urban inhabitants. This first ever global survey finds that applying three types of new mobility services – electric, on-demand minibuses, subsidized shared rides, and trip-planning and ticketing apps – can make public transport more affordable, accessible and sustainable, if integrated properly. 

Most developed countries now pursue policies that implicitly or explicitly aim at promoting compact urban form. This report analyses more than 300 academic papers that study the effects of compact urban form. 

Ethiopia has recognised the critical role that well-managed urbanisation will play in realising its ambition to achieve middle income status by 2025. Given the extended lifecycle of urban infrastructure, a small number of key decisions over the next five years will shape and lock in Ethiopia’s urban future for many decades to come. 

The report recommends that parties to the Montreal Protocol approve an amendment to phase down the production and use of HFCs. In addition, countries that are not already working to phase down HFCs should begin developing and implementing domestic regulations to do so, while also increasing their appliance energy efficiency standards. Incorporating HFC production and consumption into the Montreal Protocol would provide significant near-term gains to slow climate change and could lead to avoiding 1.1–1.7 GtCO2e of annual GHG emissions per year by 2030. 

This note describes the Commission’s assessment of future infrastructure investment needs. It presents projections for a baseline scenario, and the estimated incremental investment required for a low-carbon scenario. It sets out the sources used and provides an overview of the estimates and modelling undertaken by the New Climate Economy (NCE) network.
