Greenhouse gas emissions study

(a) No later than April 15, 2027, DOEE shall solicit proposals for the purpose of issuing a grant in the amount of $200,000 to an organization with expertise in attribution science to conduct a study on the total costs of greenhouse gas emissions in the District between the years of 1995 and 2024 and to compile the report described in subsection (c) of this section. (b) No later than June 15, 2027, DOEE shall select the grant recipient to conduct the study. (c) The grant recipient, alongside DOEE, shall compile a report detailing the findings of the study that shall include: (1) A summary of the various cost-driving effects of greenhouse gas emissions from the relevant time period on the District, including effects on public health, natural resources, biodiversity, agriculture, economic development, flood preparedness and safety, housing, and any other effect that the grantee and DOEE determine to be relevant; (2) A categorized calculation of the costs that have been incurred and costs that are projected to be incurred by the District and its residents for each effect identified under paragraph (1) of this subsection; (3) A categorized calculation of the costs that have been incurred and costs that are projected to be incurred by the District and its residents to adapt to the effects of covered greenhouse gas emissions during the covered period; and (4) An economic analysis to determine whether there would be a cost passed on to taxpayers as a result of requiring each fossil fuel company that has a sufficient nexus to the District and emitted more than 1 billion tons of greenhouse gas emissions globally between 1995 and 2024 to compensate the District for costs related to necessary adaptation to and disaster recovery from intensifying extreme weather. (d) The report shall be submitted by the grant recipient to the Mayor and the Council committee with jurisdiction over DOEE no later than June 15, 2028. (e) If requested, the grant recipient shall appear before the Council committee with jurisdiction over DOEE to report on the total assessed cost of greenhouse gas emissions in the District based on the findings of the study.
