San Francisco, Sep 9: As cities around the world accelerate efforts to meet their commitments to the Paris climate agreement, a new research on Sunday showed that ambitious urban climate policies can vastly reduce carbon emissions globally.

The research has been conducted by C40 Cities, The Global Covenant of Mayors for Climate and Energy and the NewClimate Institute.

Titled "Climate Opportunity: More Jobs; Better Health; Liveable Cities", the research estimates that by 2030 a boost in urban climate action can prevent approximately 1.3 million premature deaths per year, generate 13.7 million jobs in cities and save 40 billion hours of commuters' time plus billions of dollars in reduced household expenses each year.

Funded by Bloomberg Philanthropies, the report examines a number of effective urban solutions to climate change, including energy efficiency retrofits in buildings, enhanced bus networks and district-scale renewable energy.

It shows that these climate actions are strong drivers of positive public health and economic outcomes across countries and regions.

Its findings show investments in residential energy efficiency retrofits will result in a net creation of 5.4 million jobs in cities worldwide.

These investments will also result in significant household savings, as well as emissions reductions.

Improved bus services and more extensive networks can prevent the premature deaths of nearly one million people per year from air pollution and traffic fatalities worldwide.

It says district-scale renewable energy for heating and cooling in buildings can prevent a further 300,000 premature deaths per year by 2030, as well as create approximately 8.3 million jobs and contribute to significant emissions reductions.

Overall, climate action policies can have proportionally greater outcomes for lower income groups in developing cities, where populations have the most to gain from the introduction of new technologies.

"Climate Opportunity shows what the mayors of the world's great cities have known for a long time: climate, public health, and a strong economy are deeply connected," C40 Cities Executive Director Mark Watts said in a statement.

"We need cities around the world to implement the bold climate policies detailed in this report, if we are to avoid catastrophic climate change."

Thomas Day, partner at NewClimate Institute who led the research, said: "Cities account for 73 per cent of global greenhouse gas emissions, making large-scale climate action in urban areas an urgent focus of efforts to meet the highest goals of the Paris Agreement."

The release of the research comes just ahead of next week's Global Climate Action Summit in San Francisco, a global gathering of policymakers, scientists, businesses and activists committed to the goals of the Paris Agreement.

In the lead-up to the summit, C40 Cities and the Global Covenant of Mayors invited mayors to enhance their commitments to bold climate action, as part of the "One Planet Charter."

Mumbai (PTI): In view of Argentine superstar footballer Lionel Messi's visit to Mumbai on Sunday, the city police are implementing stringent security measures, like not allowing water bottles, metals, coins inside the stadiums and setting up watchtowers to keep an eye on the crowd, officials said.

The police also said taking extra care to avoid any stampede-like situation and to prevent recurrence of the chaotic situation that unfolded in Kolkata during Messi's visit on Saturday as thousands of fans protested inside the Salt Lake stadium here after failing to catch a clear glimpse of the football icon despite paying hefty sums for tickets.

Messi is expected to be present at the Cricket Club of India (Brabourne Stadium) in Mumbai on Sunday for a Padel GOAT Cup event followed by attending a celebrity football match. He is expected to proceed to the Wankhede Stadium for the GOAT India Tour main event around 5 pm.

"In view of Lionel Messi's visit to Mumbai, the police are geared up and have put in place a high level of security arrangements in and around the stadiums located in south Mumbai. Considering the chaos that prevailed in Kolkata and the security breach, we have deployed World Cup-level security arrangements at Brabourne and Wankhede stadiums," an official said.

Expecting heavy crowd near the stadiums during Messi's visit, the city police force has deployed more than 2,000 of its personnel near and around both the venues, he said.

As the Mumbai police have the experience of security 'bandobast' during the victory parade of ICC World Cup-winning Indian team and World Cup final match at the Wankhede Stadium, in which over one lakh cricket fans had gathered, we are prepared to handle a large crowd of fans, he said.

"We are trying to avoid the errors that occurred in the past," the official said.

There is no place to sneak inside the stadiums in Mumbai like the Kolkata stadium, according to him.

The police are also asking the organisers to provide all the required facilities to the fans inside the stadium, so that there will be no chaos, he said, adding the spectators have purchased tickets in the range of Rs 5,000 to 25,000. After paying so much of amount, any spectator expects proper services, while enjoying the event, he said.

The police are expecting 33,000 spectators at the Wankhede Stadium and over 4,000 at Brabourne Stadium. Besides this, more than 30,000 people are expected outside and around the stadiums just to have a glimpse of the football sensation, he said.

The organisers responsible for Messi's India visit recently came to Mumbai to discuss security arrangements. During the meeting, the Mumbai police asked them not to take the event lightly, according to the official.

After those requirements were fulfilled, the final security deployment was chalked out, he said.

Police has the standard procedure of the security arrangements inside the Wankhede Stadium, where people are barred from taking water bottles, metals objects, coins. Police are setting up watch towers near the stadiums and there will be traffic diversions, so that there is maximum space available to stand, according to the official.

Police are also appealing to the spectators to use public transport service for commuting and avoid personal vehicles to reach south Mumbai.

To avoid any stampede-like situation, police are also taking precautionary measures and will stop the fans some distance ahead of the stadium and public announcement systems will be used to guide the crowd. Barricades will be placed at various places to manage the crowd.

In case the crowd swells up beyond expectation, the police will divert people to other grounds and preparations in this regard underway, he said.

Additional police force has been deployed in south Mumbai to tackle any kind of situation, he said.
