Energy and Climate Change (EC) Program for reducing greenhouse gas in Scope 1 Scope 1 : Direct Emissions• Stationary CombustionWalailak University has implemented a greenhouse gas emission reduction program under Scope 1 by replacing conventional diesel fuel with Diesel B7 in all backup generators across the campus. Diesel B7 contains up to 7% biodiesel derived from renewable biological sources, providing biogenic carbon that is part of the natural carbon cycle. This substitution significantly reduces the net carbon dioxide (CO₂) emissions from fuel combustion, as the biogenic portion of the carbon is considered carbon-neutral under international GHG accounting standards. In 2025, this transition resulted in an estimated reduction of 2.28 tCO₂e/year.

Energy and Climate Change (EC) Elements 4: Materials & Resources Environmental Quality Walailak University has adopted R-32 refrigerant as an alternative to conventional refrigerants such as R-22 and R-410A. Unlike R-22, which has ozone depletion potential (ODP > 0), and R-410A, which has a high global warming potential (GWP ≈ 2,088), R-32 offers significant environmental benefits. With zero ozone depletion potential (ODP = 0) and a much lower GWP (≈ 675), R-32 reduces the impact on climate change while maintaining high cooling efficiency and energy savings.
