Chapter IV also charges the government to develop/update a range of mitigation and adaptation policies and defines dedicated accountability relationships. Art 25 charges the State to prepare a national inventory of anthropogenic emissions by sources and removal by sinks of atmospheric pollutants (INERPA) ensuring public disclosure .

Chapter V on economic and financial instruments notably 1) details green fiscal principles (art 28) that include fossil-fuel curbing measures, 2) mandates the budget allocation for climate policy purposes to be consolidated in a State Budget account (art 29), 3) charges the government to create and implement a category of tax deductions — IRS Verde — under the Corporate Income Tax Code that benefits taxpayers who purchase, consume or use environmentally sustainable goods and services (art 30), 4) subjects petroleum and energy products to a carbon price to be "determined in accordance with good international practices and with a view to achieving climate goals", and 5) defines guiding principles on climate matters that public and private entities must adopt in their financial policies, financial management, support for capitalisation and borrowing (art 34).
