Chengdu Development and Reform Commission developed its first greenhouse gas inventory in 2015 (based on 2010 data). This inventory revealed valuable insights about the sources of the city’s emissions. 

Rio de Janeiro is one of the world’s leading cities injecting sustainability into its planning. In 2011, Mayor Eduardo Paes enacted an ambitious climate change law, setting a goal to avoid 20 percent of its emissions by 2020, based on 2005 levels. There was only one problem: The city wasn’t sure just how much it was emitting, or where its emissions were coming from.

When the 2011 Newsweek Green Rankings were published, it came as a surprise to many that seven of the worst performing US companies were financial firms. The reason for such a poor performance was inadequate reporting of emissions in corporate supply chains; in the case of financial firms, emissions from their lending and investment portfolios.

A coalition of the world's biggest cities has launched an international tool that will for the first time allow many local authorities to measure their greenhouse gas emissions, providing them with a baseline...

Gujarat's 'solar city — Rajkot in Saurashtra — is being globally recognized as a case study for reducing carbon emissions. As per report by World Resources Institute (WRI), a US-based organization, presented at the UN Climate Change Conference in Peru, Rajkot will be able to reduce 14 per cent cent of its carbon dioxide emissions by 2016. 

Until now, there was no universal, comprehensive methodology for cities around the world to measure their emissions. One of the tool's creators explains its power in the fight against climate change.

Cities are not just where 3.5 billion of us live—they are where more than  half of humanity uses electricity, drives cars, and throws out garbage, among myriad other activities that emit greenhouse gases. Now, a global coalition has released the first standardized method for measuring and reporting a given city’s greenhouse gas emissions. 

With the Paris Agreement having come into force this year, 12 months after it was agreed, it is more important than ever for businesses to understand, report on, and reduce their carbon emissions.

Many financial institutions measure and report their own greenhouse gas emissions, but the real impact is in their value chains. To address this gap, the Greenhouse Gas Protocol and the United Nations Environment Programme Finance Initiative have begun developing guidance to help financial intermediaries assess the emissions from their lending and investments portfolios.

Today the World Resources Institute (WRI), C40 Cities Climate Leadership Group (C40) and ICLEI - Local Governments for Sustainability (ICLEI) launched the first widely endorsed standard for cities to measure and report their greenhouse gas (GHG) emissions at a COP20 event featuring mayors and officials from cities around the world. 

China just announced a mitigation goal to peak its emissions by 2030 or earlier, while the United States committed to reduce its national emissions by 26-28 percent below 2005 levels by 2025. And countless other cities and countries have set similar emissions-reduction targets.

More than half the world’s people live in cities, and cities are responsible for more than 70 percent of all energy-related carbon dioxide emissions on Earth. These dramatic statistics mean cities have a critical role to play in addressing climate change.

As home to 3.5 billion of the world’s population, cities and urban areas play a crucial role in combating global climate change. And today, many of their leaders are announcing steps to do just that.

Low-carbon development has become the core theme of China’s urbanization. In fact, it’s one of the country’s key strategies to achieve its target of reducing carbon intensity by 40-45 percent by 2020.

As corporate leaders track and set more ambitious targets for reducing GHG emissions—and take a broader look at Scope 3 emissions—many are looking for a way to find new opportunities to collaborate (internally and externally). Starting this month, WRI is inviting companies to road test a new collaboration tool developed as part of the Next Practice Collaborative.

On October 4th, 2011 business leaders from around the world will come together to see the new GHG Protocol standards unveiled for the first time. Simultaneous events in New York City and London will be first in a series of launch events around the world. Launch events are already planned for November 18th in Beijing and November 21st in Tokyo. These groundbreaking standards establish the first internationally agreed-upon approaches for measuring and reporting GHG emissions throughout product life cycles and corporate value chains.

A new journal, Greenhouse Gas Measurement & Management, focuses on the infrastructure to support future GHG mitigation policies by providing a scholarly forum for both academic researchers and GHG professionals.

The Philippines Greenhouse Gas Accounting and Reporting Program (PhilGARP) was officially launched at the Mandarin Oriental Hotel in Manila on November 30, 2006.

ICT companies and their customers will soon have common approaches and methodologies to calculate the carbon footprints of ICT products and services thanks to industry guidance due to be published at the end of the year.
