The emissions data are available. The reported inventory is available every year. Emissions have fluctuated over the last several years. I believe the auditor's report does have a line graph. In the absence of policy, they are projected to increase going forward, but as you'll see in the auditor's report, in the commissioner's report, with our new policies they are projected to decrease quite significantly.
