C-MACC Weekly Sustainability and Energy Transition Report
Water: The Unpriced Catalyst of Global Security
- 1st Topic of the Week: Water scarcity is no longer a distant threat—it’s a fast-emerging, systemic risk quietly reshaping agriculture, industry, infrastructure, and global capital flows in ways most still underestimate.
- 2nd Topic of the Week: China’s plunging electrolyzer costs and policy-backed PEM push are reshaping hydrogen economics, positioning it to outpace the West in scaling affordable, next-generation clean energy infrastructure.
- Otherwise – Clean tech investment remains uneven; carbon emissions demand a global lens; policy volatility is stalling circularity and renewables; and EV adoption is fracturing under economic and geopolitical strain.
Exhibit 1: Global freshwater availability is a small percentage of total water, and its market share is shrinking.
