NEW YORK, Sept 23 (Reuters) - Executives from several

major companies urged world leaders on Monday to follow through

on an international agreement, made at the COP28 summit in Dubai

last year, to triple renewable-energy capacity by 2030 to fight

climate change.

Companies including massive energy-user Amazon.com ( AMZN )

and power producers like Vestas and Iberdrola,

issued the statement at an event on the sidelines of United

Nations Climate Week in New York.

They called on countries to include quantifiable

renewable-energy capacity targets in their new national climate

plans to be submitted to the U.N. next February, and to outline

specific investment plans to ensure those goals are met.

Keeping countries focused on tripling renewable energy is

among the top themes at Climate Week and the U.N. General

Assembly, where world leaders, companies and NGOs hope to

reinforce international climate commitments.

Meanwhile, California announced on the sidelines of the

events on Monday that it had filed a lawsuit against oil giant

Exxon Mobil ( XOM ) over its alleged role in global plastic

waste pollution.

Attorney General Rob Bonta said the state decided to sue

Exxon after concluding a nearly two-year investigation that he

said showed Exxon was misleading the public about the

limitations of recycling.

Exxon rejects the claim.

The U.N. is in the midst of a slew of climate-related events

that kicked off on Sunday alongside the General Assembly.

In speeches on Sunday, some leaders warned of growing

mistrust between nations as climate-fueled disasters mount.

"International challenges are moving faster than our ability to

solve them," U.N. Secretary General Antonio Guterres told

leaders at the summit.

"Crises are interacting and feeding off each other - for

example, as digital technologies spread climate disinformation,

that deepens distrust and fuels polarization."

Prime Minister Mia Mottley of Barbados echoed Guterres'

warning and urged a "reset" in how global institutions are

governed so they can better respond to crises and serve those

most in need.
