Regulations.

Step 1: Understanding Emissions Reduction Policies There are several types of policies that can be used to encourage emissions reduction. These include taxes, subsidies, and tradable permits.

• Taxes on emissions can make it more expensive to pollute, thereby providing a financial incentive to reduce emissions.
• Subsidies can provide financial support to businesses or individuals that take steps to reduce their emissions.
• Tradable permits (also known as cap-and-trade systems) allow businesses that reduce their emissions to sell their unused emissions allowances to other businesses, providing a financial reward for emissions reduction.

Step 2: Identifying the Non-Rewarding Policy Regulations, on the other hand, do not reward emissions reduction in the same way. Regulations typically set mandatory standards for emissions and can impose penalties for non-compliance. While they can be effective in reducing emissions, they do not provide a financial reward for doing so.

So, the answer to the question "Which of the following does not reward emissions reduction?" is Regulations.
