    The launch of Mission 2020 should be welcomed by everyone who understands why tackling climate change is humanity’s most urgent task. Its focus is getting us over the first hurdle in the race to exit the Fossil Fuel Age and move into a greener, cleaner, climate-safe era for humanity. C40, which launched its own ‘Deadline 2020’ program a few months ago, will certainly be getting right behind Mission 2020.

    Mayor of Paris and Chair of C40 Anne Hidalgo and Mayor of London Sadiq Khan today announced they’re working to create schemes to score new cars based on their real-world emissions and their impact on air quality. The schemes will help consumers make better informed choices about the environmental impact of the cars they drive and prevent car manufacturers from exploiting loopholes in existing labelling schemes.

    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. Gathered in Mexico City, mayors of the Steering Committee – C40’s elected leadership – voted unanimously to adopt a target of constraining global temperature rise to no more than 1.5 degrees Celsius above the pre-industrial average (the toughest goal of the Paris Climate Agreement), and to make it a condition of C40 membership that all cities have a plan to deliver their proportionate contribution towards this goal.

    During Climate Week NYC and the UN General Assembly in New York this week, the international community marks the ratification of the Paris Agreement by 60 countries. It now seems likely that the Paris Agreement will enter into force before the next major gathering of the UN on this issue, COP22 in Marrakesh. Nation states remain committed to delivering on their ambition to limit global warming to 1.5 degrees Celsius - and cities have a key role to play, as partners to nations and regions, as innovators, and as leaders.

    BY C40 EXECUTIVE DIRECTOR MARK WATTS: A few months ago I wrote about how mayors are changing the way we think about food. Mayors are leading a revolution to improve the systems of how food is procured, produced, distributed, while minimising and managing food waste; through C40, they are working together to share best practices and new strategies.

    This week, as the UN members gather for their General Assembly, I’m participating in a panel discussion on Urban Food Systems, hosted by our partners the EAT Forum, which continues to reinforce the effectiveness of global collaboration among cities. The message that I’ll be sharing is straightforward: climate change is the biggest issue facing us at this time, and cities offer a great platform to bring about change.
