Sustainability Assessment Methodology
Each year, ASLA will update its carbon calculation methodologies to
reflect the latest data, scientific advancements, and evolving
regulations, ensuring accurate and standardized greenhouse gas (GHG)
reporting across industries and regions. These updates incorporate
changes in energy use, fuel types, industry practices, and technological
advancements.
By regularly updating these
co-efficients, regulatory bodies ensure that carbon calculations remain
accurate, reflecting shifts in carbon intensity, energy efficiency, and
technological innovations. Globally, this process is overseen by national and international regulatory bodies such as the , the , and the . For example, the
is updated annually with the latest emission factors for electricity
generation in the U.S. while the EEA provides carbon co-efficients for
EU member states based on energy consumption and grid performance data.
Through its ,
the IPCC offers a global framework with standardized emission factors
that countries around the world use to align their carbon calculations
with the latest science.
Businesses and governments use these updated
emission factors to meet regulatory compliance and international climate
goals, such as those outlined in the Paris Agreement.
