The policy brief argues that border carbon adjustments (BCAs) are a more effective tool for addressing emissions leakage than traditional 'behind the border' measures like free allowances. It outlines a specific six-step design process: determining scope and coverage, calculating embedded carbon, determining the adjustment level, deciding revenue use, establishing an expiration date, and ensuring a fair and transparent process. The authors recommend that BCAs focus on primary goods in high-carbon sectors, apply only to imports to avoid WTO subsidy issues, and exempt Least Developed Countries. Revenue generated should be used to support environmental objectives and benefit affected developing countries. The brief also notes that while BCAs have been proposed in the EU and US, they are rarely implemented.

The report details a whole-systems approach to data center design, focusing on reducing 'native loads' (CPUs and servers) to create compounding energy savings upstream in cooling and power systems. It proposes a 'Hyperserver' concept that reduces power from 128W to 21W, advocates for liquid cooling to replace inefficient fans, and recommends onsite AC power generation with the utility grid as backup. The document argues that current industry incentives, such as charging by square footage, are perverse and should be replaced by metrics based on power density and actual lifecycle costs.
