Emisiones territoriales y fuga de emisiones : análisis del caso español

open access: yesRevibec: revista iberoamericana de economía ecológica, 2012
Habitualmente las estadísticas oficiales consideran exclusivamente las emisiones que un país produce en el interior de su territorio.

Environmentally adjusted productivity growth and shadow prices for dairy farms

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, Volume 74, Issue 2, Page 99-123, June 2026.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 783-791, May 2026.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

The Conditions for Emissions: Exploring the Dynamics of Carbon Policy Emissions Across the United States

open access: yesPolitics &Policy, Volume 54, Issue 2, April 2026.
ABSTRACT In this paper, we investigate the adoption of carbon pricing policies within the U.S. across states. While policymakers have many tools at their disposal, carbon pricing is a policy option that utilizes market theories to curtail harmful effects from emissions through pricing structures.
