This is another example of what we mean when we say "Standards are the seed corn for compliance revenue".

A change in the weather is sufficient to create the world and oneself anew.

—Marcel Proust, 1920


The Leonardo Academy Inc. (LEO), a non-profit, ANSI-accredited standards developer, proposes to new consensus product titled LEO 3000 Climate Accounting Standard.   An excerpt from the filing in ANSI’s Project Initiation Notification System* is shown below:

New Standard: LEO 3000-201x, Climate Accounting Standard (new standard)

Human-caused activities and emissions have altered the earth’s energy balance, leading to the trapping of excess energy in the atmosphere, which in turn is disrupting the climate and causing global temperatures to rise. Current accounting methods have only accounted for a portion of the total contributors to this excess trapped energy. “Radiative Forcing” is the universal metric that can be used to describe the degree to which any given emission, natural process, or activity contributes positively or negatively to this change in the energy balance. The IPCC has begun using this metric to project future climate change scenarios. By translating IPCC methods into an accounting protocol, it will be possible to more accurately and comprehensively assess the contribution of all climate pollutants, to determine the level of Radiative Forcing reduction required to stabilize climate, and to develop a roadmap toward climate stabilization that accomplishes the goal in a timely and cost-effective manner.  Stakeholders: Climate affects everyone and everyone affects climate through their actions and choices. The stakeholders for this standard include the consumers, government representatives, environmentalists, academics, businesses, and others.

This is a climate accounting standard. This specification standard will provide a radiative forcing-based climate accounting protocol, which is an application of IPCC consensus climate science presented in the Fifth Assessment Report (AR5), and used in subsequent reports, including the IPCC’s Special Report: Global Warming of 1.5°C. This protocol is intended to specify the methods for calculating climate footprints which include all known contributors to net positive radiative forcing, for determining the scale of radiative forcing reduction needed to stabilize climate, and for identify and supporting projects aimed at stabilizing the global climate system significantly below +1.5°C by 2030 and in decades to come. It will also specify the requirements for validation and verification of claims. Finally, it will describe potential funding mechanisms to achieve stabilization goals most cost effectively, including direct investments in eligible Radiative Forcing reduction projects and infrastructure, governmental and market incentives, and public mitigation exchange platforms.

No public comments are due at this time; though other ANSI-accredited standards developers may need to examine whether or not there is scope overlap.   Leonardo Academy’s standards development page is linked below:

This standard falls into a cross-disciplinary niche we identify as “Global Warming Engineering” but we will continue to keep it on the agenda of the traditional building service engineering.  We are happy to discuss this consensus product any day at 11 AM Eastern time.  We will place it on the agenda of our monthly Mechanical Engineering teleconference.  See our CALENDAR for the next online meeting; open to everyone.
