Measuring, Reporting & Verification

November 19, 2007

The Big Picture

As companies are becoming increasingly aware of climate change issues, many realize that managing greenhouse gases requires tracking company emissions accurately. Stakeholders also are increasingly interested in having a way to track companies’ performance in managing greenhouse gases. These internal and external needs have led to greater interest in standards for measuring emissions, and reporting mechanisms that are run or verified by third parties.

Strict standards should be used in measuring and reporting greenhouse gas emissions. This ensures a level of confidence in reported emissions as companies develop a climate strategy.

Key Players

There are several industry groups, government agencies, and nonprofit organizations that help companies measure and report emissions.

Standards and protocols. Several multi-stakeholder groups have been created to generate common standards that are generally accepted across companies, sectors, and geographic borders. These groups have created spreadsheets for measuring, along with documents explaining related issues.

The Greenhouse Gas Protocol Initiative is the largest international effort to create common measuring standards applicable to large and small companies. It is a multi-stakeholder initiative convened by the World Business Council for Sustainable Development and the World Resources Institute. The GHG Protocol Initiative is comprised of a wide range of businesses, nongovernmental organizations, and governments from around the world. The objective is to develop internationally accepted measuring standards for GHG emissions and to promote use in companies and other organizations.

Others have used the GHG protocols as a basis for creating geographic- or industry-specific reporting protocols, or simply as a starting point for helping companies with their climate efforts. For example, The US EPA’s Climate Leaders program is a partnership between government and industry that has adapted the GHG Protocol Initiative to create its own standards as well as developing additional tools and resources to help companies. EPA also offers technical assistance to companies and can help company programs with publicity.

Emissions registries. Companies may be interested in reporting their emissions through a registry, instead of relying solely on their own reports. Reporting through an established third-party registry adds credibility to company statements and can provide publicity and recognition to the company.

The California Climate Registry, for example, combines standards with a reporting function. Created by California statute as a non-profit voluntary registry, this program helps companies and organizations to establish GHG emissions baselines against future GHG emission reduction requirements that may be surface. Registry is accepted from a broad spectrum of participants, including utilities, businesses, industry, government agencies, educational institutions, nonprofit organizations and other entities. The registry has developed a set of measuring protocols that are aligned with the GHG Protocol Initiative, but adapted to California.

The U.S. Department of Energy (DOE) also runs a public emissions reporting program called the Voluntary Reporting of Greenhouse Gases Program, enabling any company, organization or individual to establish a public record of emissions, reductions, or sequestration achievements in a national database maintained by DOE.

Non-US measuring and reporting programs. Other countries have similar GHG reporting programs. One example is Canada’s Voluntary Challenge and Registry (VCR Inc.), a public-private partnership working across all sectors to get companies to voluntarily report and, eventually, reduce emissions. Another example is Britain’s Climate Change Projects Office, which works with companies in the U.K.

Corporate efforts. The Global Environmental Management Initiative (GEMI), a non-profit, works with existing measuring and reporting standards instead of developing its own protocols. GEMI helps its member companies understand how to measure emissions and then how to take action to reduce emissions. Information on the GEMI Web site is useful to non-member companies as well.

Many companies report emissions through annual reports, web sites, and other public records. BP, for example, reports its greenhouse gas emissions on its site. BP Amoco was the first major company committed to reducing its GHG emissions to a specified level, therefore setting a precedent for other companies to follow. The company also commissioned an auditing team that developed the first-ever industry GHG emissions audit process consistent with international financial and environmental auditing standards.

The Upside

There are numerous reasons for companies to be involved with measuring and reporting, including:

  • Identifying opportunities for cost and energy savings. Greenhouse gas emissions are closely linked to energy use, so measuring emissions can lead to identifying ways to reduce emissions, which can in turn lead to cost savings.
  • Protocol development. By becoming involved, a company can influence protocol development and become familiar with measuring and reporting methods, processes, and issues.
  • Ensuring the company is functioning within regulatory requirements. Accurate measurements, based on commonly agreed-upon standards, are a necessary first step towards such emissions trading and other regulatory changes. As government protocols emerge and develop, it becomes increasingly important for businesses to be aware of their emissions levels.

Reality Check

  • Complex questions. Measuring greenhouse gas emissions can be difficult. Questions of scope and boundaries exist (i.e. where and how far to draw the “bubble”), and despite the development of reporting protocols, some questions are ultimately judgment calls by the company.
  • Inexact data. Some information may have to be estimated. For example, a company that shares a building with others may not be able to accurately measure its energy consumption. Measurements would need to be estimated based on a number of variables.
  • Time, money, and other resources. The process of deciding how and what to measure can be difficult and time-consuming. The amount of time needed to develop measuring and tracking processes depends on the size and operations of a company, among other factors. Manufacturing companies will generally have more complicated emissions measurements than office-based organizations, but measurements can be complex for any company. However, tracking emissions can bring security to the company as protocols continue to develop. If measurements are taken regularly, it is easier to asses what must be done in order to meet upcoming regulations.

    Action Plan

    At a simple level, measuring emissions entails the following elements:

  • Determining boundaries. It is necessary to determine which activities should be included in the company’s measurements. For example, the GHG Protocol Initiative suggests inclusion of business travel. Companies might also want to take into consideration issues such as employee commute, supplier emissions and product transportation. Such questions demonstrate the challenges in drawing appropriate boundaries.
  • Identifying emissions activities. Once boundaries are established, the next step is to determine what emissions are generated within those boundaries. For example, a manufacturing process may burn fossil fuels on-site, and use electricity produced by a local utility. An office-based organization may generate emissions through heating and electricity use, production of paper-based reports, and employee travel.
  • Calculating emissions. The GHG Protocol Initiative provides emissions factors for many fuels, making it easy to calculate, for example, how much CO2 is produced by burning 100 gallons of gasoline, or how much CO2 is produced by using 1000 kilowatts of electricity in California.

    Leads
  • GHG Protocol Initiative is the source for information on the GHG Protocol work. The GHG Protocol Initiative is a partnership of numerous companies and organizations, led by the World Resources Institute and World Business Council for Sustainable Development.
  • World Resources Institute is a Washington D.C.-based nonprofit organization. A web page listing WRI’s climate work, which includes green power market development, the GHG Protocol Initiative, and other science and policy climate work, is at wri.igc.org/climate.
  • US EPA Climate Leaders program is a government-industry partnership in which companies work with EPA to measure, report, and reduce emissions. The EPA program has adopted and modified the GHG Protocol Initiative standards. EPA also provides technical assistance in conducting a greenhouse gas inventory and publicity opportunities for companies that seek it.
  • Global Environmental Management Initiative climate change Web site contains a good introductory section on measuring emissions. GEMI has not developed its own measuring protocol, but its introductory information can make existing protocols easier to understand and use.

    Bottom Line

    Be sure to manage what is measured. If a company is serious about developing a climate strategy, then the starting point is learning how to measure emissions. This commitment is the first step towards managing emissions, which can lead to immediate cost savings help in the protection against possible future regulatory costs.
