A joint op-ed by the Mayor of Amman and Secretary General of Dubai's Executive Council

2016 was a momentous year for action on climate change. More than 120 countries, including Jordan and the United Arab Emirates, ratified the Paris Agreement to limit global temperature rise to below 1.5 degrees Celsius. As the Mayor of Amman and the Secretary General of Dubai’s Executive Council, representing the most populous cities in our two countries, we understand the magnitude of this commitment by our national governments, and are ready to help turn the aspiration of the Paris Agreement into action on the ground.

A post from C40 Executive Director Mark Watts

Early in the new year the Guardian newspaper asked some of the world’s most prominent scientists if it was still possible to prevent catastrophic climate change. The bleak assessment from all but one respondent was that it is not. One called it “on the fanciful edge of implausible”. This not only made for depressing reading, but also provided a marked contrast to the sense of determined optimism that pervaded C40’s mayoral summit a few weeks earlier.

Through C40’s Private Building Efficiency Network, cities work together to improve the energy efficiency of existing commercial and residential buildings. In 2014 several cities, led by Tokyo, developed the report Urban Efficiency: a global survey of building energy efficiency policies in cities. The report incorporated best practices from around the world, including financial incentives, sectoral benchmarking, and building optimisation programmes into city energy plans and roadmaps. Other cities used it as an evidence base to push for the introduction of new, ambitious building energy policies or expand already successful schemes. We hope the next instalment of this report will prove just as valuable.

The Lord Mayor of Copenhagen, Frank Jensen, today officially opened C40’s permanent office in the city. Drawing on the unique expertise in sustainable urban development found in Copenhagen, the new C40 office will serve as a centre for the network’s global Business, Economy and Innovation Programme. By supporting greater cooperation between C40 cities and the private sector they will help to overcome one of the major barriers to mayors delivering on their ambitious climate change agendas.
