With the latest round of global climate negotiations at an end, many countries, states, and cities around the world are taking action to reduce greenhouse gas (GHG) emissions through mitigation policies and goals. Decision-makers need to understand the emissions impacts associated with these initiatives in order to evaluate effectiveness, make sound decisions, and assess progress.

We are excited by the release of the first draft of the Global Protocol for Community-Scale GHG Emissions (GPC) to help cities around the world measure and report greenhouse gas (GHG) emissions using a more consistent protocol. Today begins a one-month public comment period on the protocol to ensure it will fit the needs of those who will be implementing it.

The Greenhouse Gas (GHG) Protocol recently partnered with the UNEP Finance Initiative in a critically important endeavor – developing guidance to help the financial sector measure its ”financed emissions” and track reductions. These types of emissions, which are associated with lending and investments, are the most significant part of a financial institution’s carbon footprint.

For the first time, leaders within the hotel industry are collaborating to reach a consensus on a single methodology for calculating carbon footprints and consistent metrics for communicating emissions.

I recently presented at the 7th Product Carbon Footprint (PCF) World Forum Summit, a gathering of experts brought together by Berlin-based think tank Thema1 “to foster and facilitate international discussion on how to assess, reduce, and communicate the impact of goods and services on the climate.”

Brazil’s farms are major, global producers of beef, soybeans, sugarcane, coffee, rice, and more. Yet they’re also major producers of greenhouse gas emissions. Two new resources aim to reduce the emissions intensity of Brazil’s agricultural sector.

At an official side event to the UNFCCC Bonn Climate Change Conference this week, C40 Cities Climate Leadership Group (C40), ICLEI– Local Governments for Sustainability, the World Resources Institute (WRI), and partners released Pilot Version 1.0 of the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC).

Thousands of companies have developed greenhouse gas (GHG) inventories in recent years as a crucial first step towards measuring and ultimately reducing their emissions. Agricultural emissions are a large part of many of those inventories: farming is currently responsible for between 10 and 12 percent of global GHG emissions. Globally, agricultural emissions are expected to increase by more than 50 percent by 2030, according to the UN Intergovernmental Panel on Climate Change (IPCC).

As India continues to experience the impacts of climate change in the form of changing rainfall patterns, heat waves, and coastal flooding, businesses are increasingly recognizing the need to mitigate and adapt. The problem is that many lack guidance on where to begin.

“To tell the story of the corporation is to tell the story of a grand bargain gone awry,” says Pavan Sukhdev in his new book, Corporation 2020: Transforming Business for Tomorrow’s World. It’s a bold statement, but he backs up his claim persuasively.

Facebook, a business that relies so heavily on people’s willingness to share information, took an important step recently by sharing some details of its own. The social networking company has, for the first time, released information about its greenhouse gas (GHG) emissions.

A report released by CDP in December 2013 on the use of internal carbon pricing by companies as an incentive and strat

Fossil fuel companies hold vast oil, gas and coal reserves that help determine their market value. These reserves are also the basis to understanding the potential climate risks of burning these fuels. Yet not a single fossil fuel company in the world discloses potential emissions from their reserves – and that is a big problem.

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.

The Greenhouse Gas Protocol launched a new guidance this week to help agricultural companies measure and manage their greenhouse gas (GHG) emissions from crop and livestock production. It is the first such international guidance for the sector, and will help underpin efforts to mitigate agriculture’s environmental impact.

Key environmental, sustainability and operational representatives from fourteen leading Indian businesses participated in the first ever GHG Clinic, i.e. capacity building and technical workshop on developing corporate inventories based on the GHG Protocol Corporate Standard and the Corporate Value Chain Standard.
