Countries face February U.N. deadline to update climate

plans

Total of $31 trillion aligned to quest for zero emissions

LONDON, June 24 (Reuters) - Some of the world's biggest

companies, finance houses, cities and regions have joined forces

to urge governments to increase their climate ambition ahead of

a February 2025 deadline to deliver their emission-cutting plans

to the United Nations.

The group has signed up to a coalition named Mission 2025.

It is convened by Groundswell - a collaboration between

non-profits Global Optimism, Systems Change Lab, and the Bezos

Earth Fund.

Corporate backers include consumer goods company Unilever ( UL )

, the world's biggest furniture retailer IKEA and

British sustainable energy company Octopus EV. Others are

represented through groups such as the We Mean Business

Coalition.

While some fossil fuel companies have drawn criticism from

environmental campaigners, others in business are frustrated by

what they see as short-sighted governments reluctant to regulate

to bring about necessary change when the evidence climate change

is becoming more extreme is mounting.

Mission 2025 aims to reassure political leaders they have

powerful support for bold action.

It is spearheaded by Global Optimism's Christiana Figueres,

who oversaw the Paris Agreement in 2015 that produced the first

truly global agreement that countries would cut climate-damaging

emissions.

Ten years on from the Paris deal, the nearly 200 countries

who agreed to it have a deadline to put forward updated

Nationally Determined Contributions (NDCs) that lay out a

country's policies towards meeting the global goal of reducing

emissions.

More than two-thirds of annual revenues across the world's

biggest companies, totalling $31 trillion, was now aligned with

the quest to reach net-zero emissions, the coalition said in a

statement, citing data from the Energy & Climate Intelligence

Unit, an independent climate thinktank.

A U.N.-backed survey this month of the public's views on

climate change across 77 countries, meanwhile, showed 80% of

respondents want their governments to take stronger action even

though some governments, concerned about re-election and

economics, have retreated from previous pledges.

Figueres told Reuters a "lack of leadership" and political

noise were to blame for insufficient policy to drive the cleaner

technologies that have shown themselves to be cheaper,

better-performing, faster to construct and a safer investment

than their incumbent rivals.

"The political economy is very clear that the future is one

of decarbonisation," she said.

More clarity from governments over the direction of public

policy was needed to give confidence to companies and others in

the real economy to invest more in the transition to a

low-carbon economy over the period to 2035.

"We think that governments are still very timid about what

they're going to be including in their NDCs," she said, citing

opposition from companies and others tied to the fossil fuel

economy, which she said smacked of desperation.

UN Climate Change Executive Secretary Simon Stiell told

delegates at a climate conference in Bonn this month that the

NDCs needed to cover "every sector and all greenhouse gases". 

To help empower governments to go further, the Mission

2025 coalition would provide the data needed to justify the

policy changes, with a focus on the 20 largest economies,

responsible for the bulk of emissions, Figueres said.

"Those will be the ones that we will be focusing more on.

Not only because they have the capacity to shift more, but also

because they have the means to do it."
