Over 500 new city actions featured on UN Climate Ambition Portal100 Cities Join UN Climate-Ambition Portal

To coincide with Earth Day, over 500 new city climate actions are being featured on the UN-hosted Non-State Actor Zone for Climate Action (NAZCA) portal. The city data presented on the NAZCA platform was reported to ICLEI’s carbonn Climate Registry – a leading database of local and subnational climate action – and the CDP cities program. 

NAZCA demonstrates the sheer wealth of climate actions of key non-state actors including municipalities, regions and investors in order to inspire others to raise their ambition in support of the new universal climate agreement.

Actions and targets, communicated by cities ranging from Amsterdam, Rio de Janeiro to Yokohama, range from increases in energy efficiency and deployment of renewables to green procurement and adaptation action. 

Christiana Figueres, Executive Secretary of the the UN Climate Convention (UNFCCC), said: “Nations will come together to sign a universal agreement on climate change at the UN Climate Conference in Paris in December. By demonstrating action on NAZCA, cities can support and catalyze ever higher ambition by governments while signaling their determination to be part of the transformation towards a healthier, safer and more secure world".

Several of the cities who have submitted information to the portal are showing leadership in terms of what science says is required to curb emissions so that the world has a chance of staying below the internationally agreed limit of maximum 2 degrees C.

According to the best available climate science, the world needs to peak global emissions in the next decade to successfully address climate change, triggering a deep de-carbonization of the global economy.

For example, Seoul, South Korea aims to cut emissions 25% by 2020 and 40% by 2030 from 2005 levels, with a range of clean energy and transport policies.

Boston, USA intends to reduce community-wide CO2e emissions by 80% by 2050 over 1990 levels through building retrofits, renewable energy sources, on-site renewable energy installations and better waste and industrial pollution management.

Jakarta, Indonesia intends CO2 emissions from government operations by 30% from 2005 to 2030 through sustainable building standards and retrofits, energy efficient lighting, solar-powered streetlights, and landfill gas capture and power generation.

Malmo, Sweden aims to increase share of renewables in final energy mix for government operations to 100% by 2020 while Puebla, Mexico intends to reduce CO2 emissions from government operations by 99% by 2050 based on 2014 levels. 

The cities being featured are part of an ongoing and wider process to showcase climate actions from non-state actors. In the run-up to the UN climate change conference (COP 21) in Paris, information on climate actions from cities, businesses, investors and subnational regions will continuously be added to the NAZCA portal. 

Many of these actions are happening in partnership with governments, organizations and international bodies, including the United Nations. 
Two such actions joining NAZCA today are the Compact of Mayors and the Compact of States and Regions.

The agenda is designed to catalyze action on climate change by governments and non-state actors before 2020, when the new global agreement is to take effect, and after 2020. Many such cooperative initiatives emerged from the UN Secretary-General's Climate Summit last September.

These include the Low-Carbon Sustainable Rail Transport Challenge; Removing Commodity-Drive Deforestation from Supply Chains and the Global Energy Efficiency Accelerator Platform.

The Paris-Lima Action Agenda was agreed at the end of last year by the Peruvian COP 21 Presidency, the incoming French COP 21 Presidency, the office of the UN Secretary-General and the UNFCCC Secretariat.
