At WRI, we like to say that “you can’t manage what you can’t measure.” For managing and mitigating climate change, one of the most fundamental measurements is a periodic inventory of the problem’s root cause: greenhouse gas (GHG) emissions from human activities.
GHG emissions inventories are carried out at several levels, including corporate, city, and state. Measuring emissions for entire nations has its unique challenges, but it’s a critical first step for any country that wants to effectively manage its contribution to global climate change. National GHG inventories provide a baseline of data and, if regularly updated, a tracking mechanism for assessing how domestic policies impact emissions.
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). The release of the GPC Pilot Version 1.0 marks an unprecedented international consensus on the greenhouse gas (GHG) accounting and reporting framework for cities and communities. For the first time, cities around the world will be able to manage and reduce their GHG impacts through a method that’s both comprehensive and easy-to-use.
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).
There is much uncertainty about how agricultural emissions should be reported in GHG inventories, a situation that hinders measurement and reduction efforts in the sector. To address this issue, the Greenhouse Gas Protocol is developing industry-wide best practices for reporting agricultural GHG emissions.
Let me ‘fess up. The state of the environment sometimes gets me down. But to be fair, Earth’s vital signs would drive any respectable emergency room doctor into a state of utter panic. Globally, two thirds of ecosystem services, such as freshwater, pollination, natural hazard regulation, have been degraded in the past 50 years. Annual rates of growth in yields of many basic crops have declined over the past 20 years. The effects of global climate change are already being felt around the world.
But attending the Ceres annual conference this week gave me a refreshing dose of optimism. Ceres, a coalition of investors, environmental organizations, and other public interest groups, drew together hundreds of businesses, investors, and non-profits to share innovative approaches for corporate sustainability. Here are three rays of hope from the conference.
The 200 or so companies at the workshop generally seemed aware that value chains can offer the largest opportunities for emission reductions. Some have already set reduction targets, such as Walmart’s goal to eliminate 20 million metric tons of GHG emissions from its supply chain by 2015, but others were unsure even where to start.
What do Apple, HP and Dell have in common – apart from making computers? They all source electronics from Foxconn, the beleaguered Chinese company under fire for working conditions at its factories.
There is a clear lesson to be drawn from the ongoing Foxconn furor. Fortune 500 companies’ supply chains are increasingly under the microscope— by consumers, investors, and the media. This scrutiny benefits not just factory workers but also the environment. And while uncomfortable for companies caught in the spotlight today, in the longer-term it will help business, too. Here’s why.
Today the GHG Protocol launches two new global greenhouse gas accounting standards - for corporate value chains (scope 3) and product life cycle emissions. Janet Ranganathan, WRI's Vice-president for Science & Research, and Pankaj Bhatia, WRI’s Greenhouse Gas Protocol Director since 2004, describe the 12-year program's critical role in business and government efforts to address climate impacts.
