Cities, Businesses and Urban Citizens Can Save the Planet from Climate Change


PRESS RELEASE: Cities, Businesses and Urban Citizens Can Save the Planet from Climate Change

Research reveals the actions needed in the world’s cities, delivered by mayors, CEO’s and citizens, to make the ambition of Paris Agreement a reality

London, UK (01 June 2017) Cities, businesses and urban citizens are today looking to the most comprehensive roadmap available on how they can deliver their part of the Paris Agreement and prevent catastrophic climate change. According to research by C40 Cities, a network of 91 of the world’s great cities committed to action on climate change, action in the next four years will determine if it is possible to achieve the vital goal of limiting global temperature rise to below 1.5 degrees Celsius.

Deadline 2020: How Cities Will Get the Job Done, reveals that the world’s megacities must act to peak emissions by 2020 and then nearly halve carbon emissions for every citizen in a decade, from an average of 5 tons CO2e per capita today to 3 tons CO2e per capita by 2030. If all cities of 100,000 people or more act on the recommendations in the report, the world will achieve 40% of the emissions reductions necessary to avoid catastrophic climate change.

Fortunately, mayors, CEOs and citizens are working together as never before to drive climate action, slash greenhouse gas emissions, tackle toxic air pollution and create sustainable, equitable and prosperous cities for future generations. This is particularly true of US cities. The 12 US cities that are members of the C40 network have already taken nearly 2,400 individual actions to respond to climate change in the past decade. From retrofitting buildings in New York City to make them more energy efficient, to the rollout of thousands of LED streetlights in Los Angeles, US cities are getting the job done.

If all US cities follow the lead shown by these C40 cities and pursue deep, rapid emissions reductions, by 2025 cities would contribute more than 1/3 of the emissions reductions needed to meet the United States’ commitments to the Paris Agreement.

“No matter what decision is made by the White House, cities are honouring their responsibilities to implement the Paris Agreement,” said Mayor of Paris and Chair of C40, Anne Hidalgo. “There is no alternative for the future of our planet.”
