La fiscalidad medioambiental, aunque esencial en la transición ecológica, presenta efec-tos regresivos que impactan especialmente en los hogares vulnerables. Para compatibili-zar sostenibilidad y justicia social, se plantea reformular la justicia tributaria mediante medidas redistributivas, como el reciclaje fiscal de ingresos verdes inspirado en la teoría del doble dividendo ambiental. Este trabajo propone concretamente integrar políticas sociales en el sistema tributario mediante la introducción en el IRPF de una deducción reembolsable de carácter redistributivo cuyo diseño se detalla.
