Momentum for a low-carbon economy is building, but much more needs to be done. International partnerships can help catalyse the economic growth and emissions reduction to get us there. The Global Commission makes 10 key recommendations in which partnerships can help deliver better growth and a better climate. 

Global aviation and shipping together produce about 5% of global CO2 emissions, and by 2050 this is expected to rise to 10–32%. Yet these sectors offer some of the most cost-effective emission reductions available today, particularly through improved fuel efficiency. The Global Commission on the Economy and Climate recommends that emissions from the international aviation and maritime sectors be reduced in line with a 2°C pathway through action under the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). 

Strong, predictable and rising carbon prices send an important signal to markets and can reduce greenhouse gas emissions without harming the economy. Around 40 national jurisdictions and over 20 cities, states and regions, have adopted or are planning explicit carbon prices, covering about 12% of global GHG emissions.

This report finds that growth strategies which fail to tackle poverty or climate change will prove to be unsustainable, and vice versa. A common denominator to the success of both agendas is infrastructure development. 

About US$90 trillion in infrastructure investment is needed globally by 2030 to achieve global growth expectations, particularly in developing countries. To achieve this, infrastructure investment needs to be both scaled up and climate objectives need to be integrated due to climate risks. The Global Commission on the Economy and Climate recommends that G20 and other countries adopt key principles ensuring the integration of climate risk and climate objectives in national infrastructure policies and plans. 

The Global Commission on the Economy and Climate recommends that cities commit to developing and implementing low-carbon urban development strategies by 2020, using where possible the framework of the Compact of Mayors, prioritising policies and investments in public, non-motorised and low-emission transport, building efficiency, renewable energy and efficient waste management. The actions suggested could reduce annual greenhouse gas (GHG) emissions by 3.7 Gt CO2e by 2030. 

This report documents a wide range of projects, programmes and plans currently being pursued by African cities as part of a new mode of low-carbon urbanism that is simultaneously helping to realise virtuous cycles of local economic development and social inclusion, as well as climate risk reduction. 

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 New Climate Economy project has estimated the extent of greenhouse gas (GHG) emission reductions that could result by 2030 from undertaking some of the measures and actions discussed in our 2014 annual report Better Growth, Better Climate. We estimate the potential emission reductions of undertaking these measures that would narrow the gap between a baseline emissions pathway and one compatible with a two-thirds chance of keeping global average warming below 2°C by at least 50% in 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.
